       Andrew Alwert and Stanley Feldman (Plaintiffs) brought putative class actions

against Cox Communications, Inc. (Cox) claiming that it violated antitrust law by tying

its premium cable service to rental of a set-top box. The district court granted Cox’s

motions to compel arbitration. It then certified the orders compelling arbitration for

interlocutory appeal under 28 U.S.C. § 1292(b), and we granted Plaintiffs permission to

appeal. They argue that the arbitration order is improper because (1) the dispute is not

within the scope of the arbitration agreement, (2) Cox waived its right to invoke


                                             2
arbitration, and (3) Cox’s promise to arbitrate was illusory, so the arbitration agreement is

unenforceable. Exercising jurisdiction under 28 U.S.C. § 1292(b), we affirm. We hold

that the arbitration clause in Plaintiffs’ subscriber agreements with Cox covers the present

litigation and that Cox did not waive its right to arbitration. We do not resolve Plaintiffs’

argument that Cox’s promises were illusory because the argument amounts to a challenge

to the contract as a whole, which is a question to be decided in arbitration.

         I.   BACKGROUND

                  A. The Arbitration Agreement

       Plaintiffs are Cox premium-cable subscribers who pay a monthly rental fee for the

accompanying set-top box. They also subscribe to Cox’s high-speed Internet service and

have the identical Internet-subscriber agreement. Language in the second paragraph of

the Introduction to the agreement gives Cox the right to modify it as it chooses: “Cox

reserves the right to modify the terms of this Agreement and prices for the Service . . . .

Cox may discontinue or revise any or all other aspects of the Service, including features

or enhancements, in its sole discretion at any time by posting changes online.” Joint

App., Vol. II at 179 (Alwert), 255 (Feldman). On November 18, 2011, Cox modified the

agreements to add new dispute-resolution provisions that included an arbitration clause

covering all Cox goods and services (not just Internet services). The clause states:

       YOU AND COX AGREE TO ARBITRATE – RATHER THAN
       LITIGATE IN COURT – any and all claims or disputes between us
       (including any parents, subsidiaries, affiliates, officers, directors,
       employees, or agents of Cox) that arise out of or in any way relate to:
       (1) this Agreement; (2) services that Cox provides to you in connection
       with this Agreement; (3) products that Cox makes available to you; (4) bills
       that Cox sends to you or amounts that Cox charges you for services or


                                              3
       goods provided under this Agreement; and (5) any services or goods that
       Cox or any of its affiliated entities provide to you under any other
       agreement . . . .

(Alwert), 262 (Feldman). The new language also includes a provision allowing

a subscriber to opt out of the arbitration clause by sending notice to Cox within 30 days

of receipt.1 And it includes a class-action waiver and a choice-of-law provision stating:

“This Agreement is governed by the laws of the state in which your billing address in our

records is located, and applicable federal law.” 

–87 (Alwert), 262–63

(Feldman). Because Cox did not mail notice of the modified agreement to Plaintiffs until

March (Feldman) and April (Alwert) of 2012, Cox contends that the agreements did not

take effect until April and May 2012. Plaintiffs make no argument disputing this

analysis, so we adopt it. See Gen. Motors Corp. v. Urban Gorilla, LLC, 

,

1227 (10th Cir. 2007).

                 B. District Court Proceedings

       In 2009 Cox subscribers in several jurisdictions filed putative class-action suits

against Cox alleging illegal tying of its premium-cable service to rental of a set-top box.

See Gelder v. Coxcom Inc., 

, 968 (10th Cir. 2012) (per curiam). Neither

1
 This opt-out provision states:
       You may opt out of this dispute resolution provision (except for the jury
       trial waiver . . . above) by notifying Cox of that intent within 30 days of
       receipt of this Agreement by sending a letter stating your intent to reject
       this dispute resolution provision to Cox . . . . Exercising this right, should
       you choose to do so, will not affect any of the other terms of this
       Agreement or other contracts with Cox and you may remain a Cox
       customer. If you opt out of the dispute resolution provision, you will not be
       required to do so again if Cox modifies this section in the future or you
       agree to a new term of service.

its New Orleans market on September 27, 2012; and Feldman filed his complaint on

behalf of Cox subscribers in its Arizona market on October 15, 2012. The various

regional actions were again consolidated and transferred to the Western District of

Oklahoma. See

that appeal was pending, the district court lifted the stay on the cases before us. Cox

answered both complaints on September 25. Eighteen days later, Plaintiffs submitted

interrogatories and requests for production of documents. Three days later, on October

16, Cox, which had not sought discovery, moved to compel arbitration in both cases.

       The district court granted the motions. It held that the arbitration clauses covered

the present litigation, that Cox had not waived arbitration, and that the arbitration clauses

were supported by consideration, not illusory promises by Cox.

        II.   DISCUSSION

                  A. Scope of Arbitration Agreement

       “[T]he first task of a court asked to compel arbitration of a dispute is to determine

whether the parties agreed to arbitrate that dispute.” Mitsubishi Motors Corp. v. Soler

Chrysler-Plymouth, Inc., 

, 626 (1985); see also AT & T Techs., Inc. v.

Commc’ns Workers of Am., 

, 649 (1986) (“Unless the parties clearly and

unmistakably provide otherwise, the question of whether the parties agreed to arbitrate is

to be decided by the court, not the arbitrator.”) Plaintiffs contend that their dispute with

Cox concerning rental of cable-service set-top boxes does not come within the provision

in the Internet-subscriber agreement to arbitrate “any and all claims or disputes between

us . . . that arise out of or in any way relate to . . . (5) any services or goods that Cox or

any of its affiliated entities provide to you under any other agreement.” Because the

district court’s interpretation of the arbitration agreement’s scope was founded on “an

analysis of the [contractual] language . . . rather than upon the credibility of extrinsic

evidence,” our review of its decision is de novo. Milk ‘N’ More, Inc. v. Beavert, 

, 1345 (10th Cir. 1992) (internal quotation marks omitted); see also O’Connor v.

R.F. Lafferty & Co., 

, 901 (10th Cir. 1992).

       We begin with a strong presumption that the dispute is arbitrable. This

presumption is not based on contract law but on the Federal Arbitration Act (FAA), 9


                                               6
U.S.C. § 1 et seq. (1925), which creates the “federal substantive law of arbitrability,

applicable to any arbitration agreement within the coverage of the Act.” Moses H. Cone

Mem’l Hosp. v. Mercury Constr. Corp., 

, 24 (1983). The FAA provides that

arbitration agreements “shall be valid, irrevocable, and enforceable, save upon such

grounds as exist at law or in equity for the revocation of any contract.” 9 U.S.C. § 2.

The Supreme Court has described this section as “a congressional declaration of a liberal

federal policy favoring arbitration agreements.” Moses H. 

. In

particular, “any doubts concerning the scope of arbitrable issues should be resolved in

favor of arbitration, whether the problem at hand is the construction of the contract

language itself or an allegation of waiver, delay, or a like defense to arbitrability.” 

see United Steelworkers of Am. v. Warrior & Gulf Nav. Co., 

, 582–

83 (1960) (“An order to arbitrate the particular grievance should not be denied unless it

may be said with positive assurance that the arbitration clause is not susceptible of an

interpretation that covers the asserted dispute. Doubts should be resolved in favor of

coverage.”). “Thus, as with any other contract, the parties’ intentions control, but those

intentions are generously construed as to issues of arbitrability.” Mitsubishi 

. “In the absence of any express provision excluding a particular grievance

from arbitration, . . . only the most forceful evidence of a purpose to exclude the claim

from arbitration can prevail . . . .” Warrior & 

–85 (emphasis

added).

       This court has already construed language in a contract governed by the FAA that

is indistinguishable in the relevant respects from language in the agreement before us. In


                                               7
Zink v. Merrill Lynch Pierce Fenner & Smith, Inc., 

(10th Cir. 1993), the

plaintiff had purchased securities through the defendant 18 months before entering into an

agreement providing that “any controversy between us arising out of your business or

this agreement shall be submitted to arbitration.” 

(emphasis added). When the

plaintiff filed a lawsuit in connection with his original securities purchase, the defendant

moved to compel arbitration. See 

court found that the arbitration clause

covered the dispute, and we affirmed. See 

Noting the presumption in favor of

arbitration (though we also said that the arbitration language was “susceptible of only one

reasonable interpretation”), we held that the agreement was “clearly broad enough to

cover the dispute at issue despite the fact that the dealings giving rise to the dispute

occurred prior to the execution of the agreement.” 

the argument that the

agreement to arbitrate “must pre-date the actions giving rise to the dispute” as “contrary

to contract principles which govern arbitration agreements.” 

here is even

broader because it covers disputes that “arise out of or in any way relate to” any Cox

goods or services. Joint App., Vol. II at 186 (Alwert), 262 (Feldman) (emphasis added).

Following Zink, we hold that the language of the arbitration agreement encompassed

Plaintiffs’ antitrust claim even though it arises out of events that predated the agreement.

We interpret the arbitration agreement to require that for any dispute between Cox and a

customer, each must henceforth seek resolution of the dispute through arbitration rather

than filing suit.

       The authority relied on by Plaintiffs does not persuade us to the contrary. In

Russell v. Citigroup, Inc., 

(6th Cir. 2014) the court held that an arbitration


                                              8
agreement did not apply to litigation between the employee and employer that had

commenced before the agreement was executed. The agreement covered “employment-

related disputes . . . which . . . arise between” the employer and employee. In part the

court based its conclusion on the language of the agreement. It said that “[t]he use of the

present-tense ‘arise’ rather than the past-tense ‘arose’ or present-perfect ‘have arisen,’

suggests that the contract governs only disputes that begin—that arise—in the present or

future. The present tense usually does not refer to the past.” 

This analysis has

some force. But it cannot overcome our Zink precedent. What Russell says about arise

could also be said about the word arising in Zink (Russell distinguished have arisen, not

arising, from the word arise) and we said in Zink that the “only . . . reasonable

interpretation” of the arising language was that it applied to a dispute predating the

arbitration agreement. In any event, the agreement in Russell did not include the

language “or in any way relate to” that appears in the agreement here. And the word

relate does not have the same temporal connotation as arise; we can say that something

arises at a particular point in time; but relate is broader and includes a relationship in

subject matter that is independent of time.

       There was, however, extrinsic evidence in Russell that could well be the sort of

“forceful evidence” of the parties’ intent that can overcome the presumption in favor of

arbitrability: The plaintiff employee had already sued the defendant employer when he

signed the arbitration agreement. See 

There was no evidence that either the

plaintiff or the defendant had consulted with an attorney from that litigation before

executing the arbitration agreement. See 

The circuit court, in our view quite


                                               9
reasonably, thought that this failure by either party would be highly unlikely if they

understood the agreement to cover the dispute being litigated. See 

that Russell is persuasive here because they were prospective

plaintiffs in the putative national class action that had been filed before their arbitration

agreements became effective. Although the district court had rejected class certification

in December 2011, it was not until August 8, 2012 (after the effective dates of the

arbitration agreements) that this court refused to consider an appeal from that denial. See

–68. Thus, Plaintiffs still had a chance to become plaintiffs in

that lawsuit when they became bound by the arbitration clause. But prospective

plaintiffs—that is, unnamed members of a putative class—are not parties to class

litigation. See Smith v. Bayer Corp., 

, 2379–80 (2011) (unnamed member

of putative class was not a “party” to proceeding in which court denied class certification,

and unnamed member is not precluded by any judgment in that litigation). And the great

weight of authority, some of which we set out in a footnote, is that the attorneys in the

putative class action do not represent them as class counsel. 2 Plaintiffs have cited

nothing suggesting that the law of Louisiana or Arizona is otherwise.


2
  See Sheinberg v. Sorensen, 

, 132 (3d Cir. 2010) (“[A] district court’s
decision to certify a class must precede the appointment of class counsel.”); Schick v.
Berg, 

, 117 (2d Cir. 2005) (under Texas law, “[u]ntil a trial court determines
that all prerequisites to certification are satisfied, there is no class action, the case
proceeds as an ordinary lawsuit, and attorneys for named class members have no
authority to represent or otherwise act on behalf of the unnamed class members” (internal
quotation marks omitted)); Hammond v. City of Junction City, 126 F. App’x 886, 889
(10th Cir. 2005) (under the Kansas Rules of Professional Conduct, “there was no
attorney-client relationship between the attorney and [a city employee with management
duties who was a prospective class member] until the class was certified”); Restatement

                                              10
       Our case is therefore quite unlike Russell. In Russell the parties to the arbitration

agreement were a single employee and a single employer who were already actively

engaged in litigation when the arbitration agreement was executed. The Russell court,

exercising common sense, could infer that the parties would surely have consulted their

attorneys if they thought the arbitration agreement could possibly cover that litigation.

No similar inference regarding Plaintiffs is possible here. Plaintiffs had no counsel with

whom to confer; nor is there even any evidence that they thought they might have an

antitrust claim against Cox when the arbitration agreement went into effect. We see no

basis for an inference that Plaintiffs must have believed that the arbitration agreement did

not encompass a dispute over set-top boxes because otherwise they would have consulted

counsel. (Nor is there any reason to believe that Cox thought these cases would not be

covered; on the contrary, it seems likely that Cox, which was facing set-top-box antitrust

claims, thought that future lawsuits on the subject would be covered by the arbitration

agreement.)3


3
  In the section of their brief entitled, “The District Court Erred in Finding That Cox’s
Arbitration Agreement Applied to Pre-Existing Class-Action Litigation,” Plaintiffs also
argue that “Cox’s arbitration agreement should be interpreted to avoid raising highly
problematic issues under Rule 23 and thus to not apply to any claim pre-existing the
effective date of that agreement.” Aplt. Br. at 19. They cite two cases in which courts
said that defendants in putative class actions had improperly submitted arbitration
agreements to putative class members. Plaintiffs do not claim, however, that the
arbitration agreement (as interpreted by the district court) is unenforceable in whole or in
part because of some problem under Rule 23, perhaps because they did not raise that
argument below. Rather, they are saying that Rule 23 poses problems for the arbitration
agreement and we should interpret the agreement to avoid having to resolve any such
problems. This is an imaginative argument, a new one for us. Courts decide whether a
contractual provision is enforceable or not; but Plaintiffs have not directed our attention
to any authority, nor are we aware of any, suggesting that a court should construe
contracts to avoid the need to resolve an enforceability issue. To be sure, a court may
adopt an otherwise less attractive interpretation of a statute to avoid addressing a
constitutional question, see Commc’n Workers of Am. v. Beck, 

, 762 (1988);
but the institutional reasons for avoiding constitutional questions hardly apply to
questions of contract enforceability.

        Moreover, we doubt whether Rule 23 suggests any limitation on the scope of the
arbitration agreement. We recognize that courts can use Rule 23(d) to restrict
inappropriate communications from counsel to putative class members. The Supreme
Court stated in Gulf Oil Co. v. Bernard, 

, 100–01(1981), “Because of the
potential for abuse, a district court has both the duty and the broad authority to exercise
control over a class action and to enter appropriate orders governing the conduct of
counsel and parties,” but such an order “should be based on a clear record and specific
findings that reflect a weighing of the need for a limitation and the potential interference
with the rights of the parties”. See Fed. R. Civ. P. 23(d); Manual for Complex Litigation
(Fourth) § 21.12, at 247 (2004) (“Rule 23(d) authorizes the court to regulate
communications with potential class members, even before certification.”). In this case,
however, we are aware of no district-court findings or any order indicating that Cox had
improperly submitted the arbitration agreement at issue. And we question whether there
was any impropriety. When Cox submitted the arbitration agreement to Plaintiffs, the
only filed antitrust case in which they were potential parties was moribund, awaiting a
decision by this court whether even to consider an appeal from the district court’s denial
of class certification. In that situation, to require Cox either to refrain from submitting
the arbitration agreement or to alert Plaintiffs that there may be subsequent class actions

                                             12
       At oral argument Plaintiffs argued that the arbitration clause should be construed

against the drafter, Cox, and that the district court’s ruling was contrary to the policy

behind the Supreme Court’s holding in American Pipe and Construction Co. v. Utah, 

, 554 (1974), which said that the statute of limitations for putative class members

is tolled during the pendency of a class action. But a contention first raised at oral

argument is not properly preserved. See Bronson v. Swensen, 

, 1104 (10th

Cir. 2007) (“[W]e routinely have declined to consider arguments that are not raised, or

are inadequately presented, in an appellant’s opening brief.”).

                  B. Waiver

       Plaintiffs also argue that Cox waived its right to arbitration. Our review of the

district court’s decision rejecting the waiver argument is de novo, except that we review

the factual findings underlying the decision for clear error. See In re 

–16.

       We have recognized two forms of waiver. The first is based on a party’s intent. A

party can “subjectively” waive its right to arbitration if it intentionally relinquishes or

abandons that right; once it has done so, it has no right to demand arbitration later. See

Hill v. Ricoh Americas Corp., 

, 773 (10th Cir. 2010). Second, and much


in which they could become parties, would be breaking new ground. Plaintiffs have not
presented any authority, or even argued, that a person proposing an arbitration agreement
must alert the other contracting person about litigation that might be filed in the future
that could come under the agreement. We need not decide whether failure to alert the
other person about pending litigation may foreclose application of the arbitration
agreement to that previously filed case, as in In re Currency Conversion Fee Antitrust
Litig., 

(S.D.N.Y. 2005) and Long v. Fid. Water Sys., Inc., No. C-97-
20118 RMW, 

(N.D. Cal. May 26, 2000).

                                              13
more commonly, a party’s conduct in the course of litigation can foreclose it from the

right to switch to arbitration, regardless of its intent. If it has proceeded too far in the

litigation, so that switching to arbitration could create significant inefficiencies in the use

of both the court and arbitrators or could prejudice opposing parties, we say that allowing

the party to demand arbitration would be “improperly manipulating the judicial process.”

Id.; see 

       We have found it useful to examine the following six factors in assessing whether

there has been a waiver of the right to arbitration:

       (1) whether the party’s actions are inconsistent with the right to arbitrate;
       (2) whether the litigation machinery has been substantially invoked and the
       parties were well into preparation of a lawsuit before the party notified the
       opposing party of an intent to arbitrate; (3) whether a party either requested
       arbitration enforcement close to the trial date or delayed for a long period
       before seeking a stay; (4) whether a defendant seeking arbitration filed a
       counterclaim without asking for a stay of the proceedings; (5) whether
       important intervening steps (e.g., taking advantage of judicial discovery
       procedures not available in arbitration) had taken place; and (6) whether the
       delay affected, misled, or prejudiced the opposing party.

, 467–68 (10th Cir. 1988) (internal

quotation marks omitted and brackets replaced by parentheses). The Peterson factors are

not exclusive; the list “was not intended to suggest a mechanical process in which each

factor is assessed and the side with the greater number of favorable factors prevails.”

. Rather, the analysis must be tethered to the fundamental reasons

for finding waiver. 

of persuasion lies with the party claiming that the right to demand

arbitration has been waived.” 

(“A party asserting a



                                               14
waiver of arbitration has a heavy burden of proof.”). We resolve any doubts in favor of

arbitration. See Moses H. 

–25 (the presumption in favor of

arbitration applies to “an allegation of waiver, delay, or a like defense to arbitrability”

(emphasis added)); 

.

        Applying the Peterson factors to Cox’s conduct, we hold that it did not waive its

right to arbitration. Regarding factor (1), its actions in these two cases were consistent

with an intent to arbitrate: it moved to compel arbitration just three weeks after

answering the complaints and three days after receiving discovery requests from

Plaintiffs. Indeed, the district-court order granting Cox’s motion to compel arbitration

noted that the parties had anticipated Cox’s seeking to enforce the arbitration agreement.

Similarly, factors (2) and (3) do not support waiver because Cox initiated no discovery

and moved to compel arbitration shortly after Plaintiffs made discovery requests, so it did

not substantially invoke the litigation machinery or request enforcement of the arbitration

agreement close to trial. Nor did Cox’s answers to Plaintiffs’ complaints include any

counterclaims (factor (4)). As for factor (5), there were no “important intervening steps”

other than filing answers in these two cases between the filing of suit and the arbitration

demand, and even if we consider the Healy litigation, Plaintiffs have failed to point to

any advantage that Cox would obtain over Plaintiffs in these two cases from the

proceedings (including discovery) in Healy. Finally, Plaintiffs have failed to explain how

they would have been better off if Cox had moved to compel arbitration earlier (factor

(6)).




                                              15
       Plaintiffs invoke our waiver ruling in Healy, the bellwether case in the Cox

multidistrict litigation, as support for waiver here. In Healy we agreed with the district

court (1) that Cox’s failure to inform the district court about the arbitration agreements

until after class certification and its moving for summary judgment the same day it

moved to compel arbitration were inconsistent with an intent to arbitrate, see In re 

; (2) that Cox had substantially invoked the litigation machinery through

numerous briefs and motions, including an appeal of class certification to this court, see

id.; (3) that Cox did not move to compel arbitration until close to trial, see id.; (4) that the

parties made ample use of discovery, which is more limited in arbitration, see 

and (5) that not only did Healy suffer prejudice from Cox’s delay because, among other

things, it would be necessary to reexamine class certification if a large percentage of class

members had to arbitrate their claims, but also the court was prejudiced by having spent

judicial resources on the class-certification analysis and adjudication of motions and

discovery disputes, see 

affirmed the district court’s ruling that Cox had

waived its right to compel arbitration. See 

       The facts here are quite different. The district court (with the same judge as in

Healy) said:

       While certainly there is some overlap in the nature of the claims, the cases
       are distinct. As Defendant notes, as a result of the agreed stay, there has
       been little if any work conducted in this case. Finally, none of the actions
       taken by Cox in the Healy case on which the Court based its finding of
       waiver have occurred in this case.

Joint App., Vol. IV at 651 (Feldman), 656 (Alwert).




                                              16
       As we understand Plaintiffs’ briefs, they are basing their waiver argument on

Cox’s agreement to stay Plaintiffs’ litigation while the Healy bellwether case proceeded.

They seem to be contending that Cox had indicated its preference for litigation over

arbitration by proceeding in court in Healy, but that Cox, now unhappy with adverse

rulings in Healy, is seeking a new forum to resolve this related litigation without

suffering any consequences of those rulings—thus prejudicing both Plaintiffs and the

judicial process.

       We reject Plaintiffs’ argument. We fail to see how a party that has yet to begin

litigating a pending claim can waive its right to arbitrate that dispute by having

participated in earlier litigation of a distinct claim against a different party. With respect

to subjective waiver, people frequently change their minds after a negative experience.

The fact that a party wants to litigate one case does not mean that it will want to litigate a

future case if its litigation experience convinces it that arbitration would be preferable. In

any event, Plaintiffs have not argued such subjective waiver by Cox, and the record

would not support it.

       As for waiver by conduct, a party cannot be said to manipulate the judicial process

by seeking to arbitrate a claim unless the party has litigated the same claim. If the present

claim has not been litigated, the parties are still going to have to go to some forum—

arbitration or litigation—to resolve it. And if the party now seeking arbitration has done

nothing in the earlier litigation beyond what was appropriate in that litigation, its conduct

in that litigation could hardly be an improper imposition on the court or opposing parties

in the pending dispute. Whatever happened in the other litigation was going to happen


                                              17
regardless of whether the pending claim is arbitrated or litigated. In short, the party

seeking arbitration cannot be accused of imposing a burden on the court or opposing

parties by seeking arbitration of the present claim after litigating a different claim earlier.

       Thus, the circuits to address the issue have said that waiver cannot be based on

prior litigation unless the litigation was between the same parties and involved essentially

the same claim as the one to be arbitrated. See Doctor’s Associates, Inc. v. Distajo, 

, 132–34 (2d Cir. 1997); Microstrategy Inc. v. Lauricia, 

, 250 (4th

Cir. 2001); Subway Equipment Leasing Corp. v. Forte, 

, 328–29 (5th Cir.

1999); see also Grumhaus v. Comerica Securities, Inc., 

, 652 (7th Cir.

2000) (“We agree that different claims may arise from a common factual basis, and that

in one claim, a party may wish to waive arbitration while preserving that right in the

other. [But] when the same issues are presented, a party may not escape the effect of its

waiver by minimally restyling the claim and presenting it for arbitration.”)

       Agreeing with those circuits, we hold that there was no waiver here. First, the

claim in Healy is not the same as Plaintiffs’ claims. The three cases alleged antitrust

violations in three different markets: Healy in Oklahoma, Alwert in Louisiana, and

Feldman in Arizona. The very reason the district court rejected a national class to

challenge Cox’s conduct was that the different markets raised different factual issues.

Second, the parties are different. Plaintiffs are not parties in Healy. The difference in

parties is dispositive. In Doctor’s Associates the court “easily dispose[d]” of the claim

that a party had waived its right to arbitrate claims against a party that it had not litigated

against; it noted its prior decision that a party “obviously had not waived its right to


                                              18
arbitrate claims brought by franchisees against whom [the party] had never instituted

(internal quotation marks omitted).

       Plaintiffs offer only one case to support their claim that Cox waived its right to

arbitrate in this case by participating in the Healy litigation: PPG Indus., Inc. v. Webster

Auto Parts, Inc., 

(2d Cir. 1997). But that decision concerned two cases

consolidated before the same court that involved the same parties and, for the most part,

the same claims. Further, the court noted that in Case 1 the party seeking arbitration of

Case 2 had pursued discovery relevant only to a claim in Case 2 that was not presented in

Case 1. 

We note that PPG was decided by the same court that decided

Doctor’s Associates and in no way suggested any criticism of its earlier decision.

       We recognize that Plaintiffs’ suits and Healy were consolidated in part for

multidistrict litigation. But “[c]ases consolidated for MDL pretrial proceedings

ordinarily retain their separate identities.” Gelboim v. Bank of Am. Corp., 

,

904 (2015) (dismissal order was final, appealable judgment despite pendency of other

cases in the MDL).4 Consolidation does not “meld [one] action and others in the MDL

into a single unit.” 

Plaintiffs have not pointed to anything relevant to waiver

that would distinguish the situation before us from one with no MDL consolidation.


4
  Gelboim recognized, however, that some cases (unlike the ones before us) may lose
their separate identities in MDL pretrial proceedings. See 

at 904 n.3. If
the parties “elect to file a ‘master complaint’ and a corresponding ‘consolidated answer,’
which supersede prior individual pleadings . . . , the transferee court may treat the master
pleadings as merging the discrete actions for the duration of the MDL pretrial
proceedings.” 

no merger, however, if these pleadings are not meant to have
legal effect but serve only administrative convenience by summarizing the claims of all
plaintiffs. See 

recognize that Plaintiffs alleged that permitting arbitration would prejudice

them in three ways: (1) during the stay, while the bellwether litigation in Healy

continued, Cox was able to learn about Plaintiffs’ theories by obtaining discovery in the

Healy litigation from the same experts that Plaintiffs would use in these cases; (2) if

Plaintiffs had known that Cox would later try to arbitrate the claims, they would not have

agreed to the stay but would have pursued their claims through arbitration; and (3) by

staying these cases during Healy, Cox could wait to see what the rulings would be in that

litigation and then decide whether litigation or arbitration would be more advantageous to

Cox in Plaintiffs’ cases. We are not persuaded that Plaintiffs were prejudiced in these

respects. They benefited at least as much as Cox by the Healy discovery (which did not

include any discovery from Plaintiffs). They have presented nothing to suggest that they

would have wished to arbitrate their claims sooner if they had thought that arbitration

would be demanded by Cox later. And the whole purpose of bellwether litigation, such

as Healy, is to enable other litigants to learn from the experience and reassess their tactics

and strategy (and, hopefully, settle).5 To complain that an opposing party made an

 See Manual for Complex Litigation (Fourth) § 22.315, at 360 (2004) (“[Bellwether]
cases should produce a sufficient number of representative verdicts and settlements to
enable the parties and the court to determine the nature and strength of the claims,
whether they can be fairly developed and litigated on a group basis[,] and what range of
values the cases may have if resolution is attempted on a group basis.”); Eldon E. Fallon,
Jeremy T. Grabill, & Robert Pitard Wynne, Bellwether Trials in Multidistrict Litigation,
82 Tul. L. Rev. 2323, 2338 (2008) (“First, bellwether trials allow coordinating counsel to
hone their presentation for subsequent trials and can lead to the development of ‘trial
packages’ for use by local counsel upon the dissolution of MDLs. Second, and perhaps
more importantly, bellwether trials can precipitate and inform settlement negotiations by
indicating future trends, that is, by providing guidance on how similar claims may fare
before subsequent juries.”); Duke Law Ctr. for Judicial Studies, Standards and Best

unwelcome decision based on bellwether litigation (surely the Plaintiffs could increase

their settlement demands) is to attack the bellwether process itself.

       In any event, the prejudice claimed by Plaintiffs is not the type of prejudice that

we consider in assessing whether a party has waived by conduct its right to demand

arbitration. As stated in Doctor’s 

, “[P]rejudice . . . refers to

the inherent unfairness—in terms of delay, expense, or damage to a party’s legal

position—that occurs when the party’s opponent forces it to litigate an issue and later

seeks to arbitrate that same issue.” Accord Subway 

. Cox is

seeking to arbitrate the claims raised against it by Plaintiffs, which have not previously

been litigated.

       We agree with the district court that Cox has not waived its right to demand

arbitration against Plaintiffs.

                  C. Illusory Contract

       The FAA provides that arbitration agreements “shall be valid, irrevocable, and

enforceable, save upon such grounds as exist at law or in equity for the revocation of any

contract.” 9 U.S.C. § 2 (emphasis added). Plaintiffs contend that Cox’s arbitration

clause is not enforceable because Cox’s promises under the clause are illusory. They rely

on language in the introduction of their Internet-subscriber agreement:

       Cox reserves the right to modify the terms of this Agreement and prices for
       the Service . . . . Cox may discontinue or revise any or all other aspects of

Practices for Large and Mass-Tort MDLs, 21 (2014) (“Bellwether trials may provide
useful information to the parties regarding the likely outcome of other cases at trial, such
as: (a) how well or poorly the parties’ fact and expert witnesses perform in a trial setting;
and (b) decisions on key legal issues and the admissibility of key evidence.”).

                                             21
       the Service . . . in its sole discretion at any time by posting changes online.
       Your continued use of the Service after changes are posted constitutes your
       acceptance of this Agreement as modified by the posted changes. The
       updated, online version of this Agreement shall supersede any prior version
       of this Agreement . . . .

Joint App., Vol. II at 179 (Alwert), 255 (Feldman) (emphasis added). The term

“Agreement” refers to the Internet-subscriber agreement as a whole. See 

this language to mean that Cox may modify the Agreement’s terms at any time.

And because its terms include the arbitration clause, that clause may also be unilaterally

modified at any time. Plaintiffs argue that this right to modify makes the arbitration

clause unenforceable.

       Plaintiffs may be correct. But that is an issue for the arbitrator, not the district

court or this court. As we will explain more fully below: (1) Under the FAA, unless the

arbitration provision states otherwise, the question of the enforceability of a contract as a

whole is a matter for the arbitrator. Only if an enforceability argument applies only

specifically to the arbitration provision (such as a claim that the provision is

unconscionable or that a party was defrauded into agreeing to the arbitration provision) is

enforceability to be decided by the court. (2) Although Plaintiffs frame their “illusory”

argument as directed at the arbitration provision of the Internet-service agreement,

general contract law does not permit such an argument on a provision-by-provision basis.

This proposition follows once one understands the basis of an “illusory” argument. An

illusory promise is not a real promise, although it may appear to be one. Whereas a real

promise can be consideration for a contract, an illusory promise cannot. If all the

consideration given by one party to a contract consists of illusory promises, then the party


                                              22
has provided no consideration and cannot enforce the contract. But an illusory promise

in just one provision does not make the contract unenforceable. Consideration may

appear in a separate provision. Therefore, Plaintiffs must show that nowhere in the

service agreement has Cox provided consideration, and that showing goes to the

enforceability of the contract as a whole. (3) General contract law may not apply here if

the law of Arizona (for Feldman) or Louisiana (for Alwert) does not follow that law. It is

conceivable that a state’s contract law could require consideration in each provision of

the contract. But Plaintiffs have not shown that to be the case. We now turn to each of

these three matters.

       First, almost 50 years ago the Supreme Court held that the arbitrator, not a court,

should determine whether a contract including an arbitration provision is enforceable.

See Prima Paint Corp. v. Flood & Conklin Mfg. Co., 

(1967). Prima Paint

had contracted to purchase the paint business of Flood & Conklin (F&C). See 

The contract had an arbitration clause. See 

Shortly after Prima Paint’s first

payment was due, it complained that F&C had falsely represented that it was solvent and

asserted that F&C had breached the contract. See 

a notice of intent to

arbitrate and Prima Paint filed suit to rescind the contract for fraudulent inducement. See

to stay the action pending arbitration. See 

It argued that “the

issue presented—whether there was fraud in the inducement of the consulting

agreement—was a question for the arbitrators and not for the District Court.” See 

court agreed, and so did the Supreme Court. The Supreme Court held that

the issue of arbitrability was resolved by § 4 of the FAA, which provides that a court


                                             23
shall order arbitration after determining that “the making of the agreement for arbitration

or the failure to comply with the arbitration agreement is not in issue.” 

(brackets and internal quotation marks omitted). Thus, it said, “if the claim is fraud in the

inducement of the arbitration clause itself—an issue which goes to the ‘making’ of the

agreement to arbitrate—the federal court may proceed to adjudicate it. But the statutory

language does not permit the federal court to consider claims of fraud in the inducement

of the contract generally.” 

–04 (footnote omitted). “[I]n passing upon [an]

application for a stay while the parties arbitrate, a federal court may consider only issues

relating to the making and performance of the agreement to arbitrate.” 

Because the plaintiff had claimed fraudulent inducement of the entire contract rather than

only the arbitration agreement, arbitration of the dispute was required. See 

       Prima Paint was recently endorsed in Buckeye Check Cashing, Inc. v. Cardegna,

(2006). The plaintiffs had entered into contracts under which they received

cash in exchange for a personal check made out for the amount of the cash plus a finance

charge. See 

They brought a class action in Florida state court, arguing that

because the contract violated state lending and consumer-protection laws, it was void for

illegality. See 

Invoking the contract’s arbitration clause, the defendant moved

to compel arbitration. See 

state supreme court held that because the contract

was unlawful the arbitration provision could not be enforced. See 

States

Supreme Court reversed. Holding that Prima Paint’s rule applies to state-court

proceedings, the Court reaffirmed that “a challenge to the validity of the contract as a

whole, and not specifically to the arbitration clause, must go to the arbitrator.” 

                                             24
Of particular importance in this circuit, the Court distinguished, without endorsing, our

decision in Spahr v. Secco, 

(10th Cir. 2003), in which we departed from

Prima Paint. In that opinion we held that, despite Prima Paint, a court can refuse to

enforce an arbitration clause in a contract if the contract as a whole is unenforceable

because of mental incapacity of a party. See 

Buckeye treated Spahr as

addressing not whether an agreement was enforceable, but “whether any agreement

between the alleged obligor and obligee was ever 

n.1 (citing

Spahr and opinions involving “whether the alleged obligor ever signed the contract” or

“whether the signor lacked authority to commit the alleged principal”).

       We now must consider whether Plaintiffs’ “illusory” argument challenges just the

arbitration provision of the Internet-service agreement or the entire agreement. We hold

that it is a challenge to the entire agreement, because the arbitration provision would be

unenforceable only if the entire agreement is unenforceable. As the Restatement

(Second) of Contracts explains, the notion of an illusory promise is simply part of the

doctrine of consideration. “Words of promise which by their terms make performance

entirely optional with the ‘promisor’ do not constitute a promise. . . . Where the apparent

assurance of performance is illusory, it is not consideration for a return promise.”

Restatement (Second) of Contracts §77 cmt. a (Am. Law Inst. 1981); see Floss v. Ryan’s

Family Steak Houses, Inc., 

, 315 (6th Cir. 2000) (“[A] promise may in effect

promise nothing at all. Such an illusory promise arises when a promisor retains the right

to decide whether or not to perform the promised act.”). It is important to keep in mind,

however, that a contract may be supported by adequate consideration, and hence be


                                             25
enforceable, even if one of the promises by a party is illusory. If that party provides other

consideration, such as a nonillusory promise, the fact that one promise is illusory is

immaterial. That consideration may appear in a totally distinct provision of the contract

as a whole. “A single performance or return promise may . . . furnish consideration for

any number of promises.” Restatement (Second) of Contracts § 80 cmt. a; see 

(“There is consideration for a set of promises if what is bargained for and given in

exchange would have been consideration for each promise in the set if exchanged for that

promise alone.”); Edwards v. First Am. Corp., 

, 1182 (9th Cir. 2015)

(“[T]he law does not require every term of the contract to have a separately stated

consideration.”). In particular, “where the agreement to arbitrate is integrated into a

larger unitary contract, the consideration for the contract as a whole covers the arbitration

clause as well.” Doctor’s Associates, Inc. v. Distajo, 

, 453 (2d Cir. 1995)

(internal quotation marks omitted) (applying Connecticut law). Further, it is undeniable

that Plaintiffs’ “illusory” argument attacks the entire Internet-service agreement, rather

than just the arbitration provisions, because the argument is based on language outside

those provisions. It is in the “Introduction” to the agreement that we find the language

“Cox reserves the right to modify the terms of this Agreement and prices for the Service

. . . [and] Cox may discontinue or revise any or all other aspects of the Service… in its

sole discretion at any time by posting changes online.” Joint App. Vol. II at 179

(Alwert), 255 (Feldman).

       We therefore conclude that Plaintiffs’ “illusory” argument, which can prevail only

as an attack on the Internet-service agreement as a whole, must be resolved by the


                                             26
arbitrator. See Lawrence v. Comprehensive Bus. Servs. Co., 

, 1164 (5th

Cir. 1987) (“Whatever inequalities exist [in the contract] could only establish non-

mutuality of obligation in the contract as a whole, not in the arbitration clause. And

Prima Paint requires that disputes concerning the contract, as opposed to the making of

the arbitration clause, be referred to the arbitrator.”).

       We recognize that this court has previously resolved whether an arbitration

agreement was unenforceable because one party’s promise was illusory. See Hardin v.

First Cash Fin. Servs., Inc., 

(10th Cir. 2006) (reversing denial of motion to

compel arbitration) and Dumais v. American Golf Corp., 

(10th Cir. 2002)

(upholding denial of motion to compel arbitration). But in Hardin it appears that the only

contract at issue was a distinct contract to arbitrate, so what we did was fully consistent

with Prima Paint. And neither opinion considered, or even cited, Prima Paint or

Buckeye (which postdated Dumais). An opinion is not binding precedent on an issue not

addressed in the opinion. See Planned Parenthood of Kansas & Mid-Missouri v. Moser,

, 830–35 (10th Cir. 2014) (distinguishing precedents which do not consider

the disputed issue). Therefore, we are free to follow the clear commands of the Supreme

Court and leave to the arbitrator to resolve Plaintiffs’ “illusory” argument.

       This leaves just one loose end to tie up. In addressing the law regarding illusory

promises, we have relied on widely accepted principles of contract law. But Feldman’s

contract is governed by Arizona law and Alwert’s by Louisiana law. What if Arizona or

Louisiana has not followed those principles? When the FAA states that arbitration

agreements “shall be valid, irrevocable, and enforceable, save upon such grounds as exist


                                               27
at law or in equity for the revocation of any contract,” 9 U.S.C. § 2, it is referring to the

law of the state that governs the contract, see Perry v. Thomas, 

, 492 n.9

(1987). It is possible that under the law of Arizona or Louisiana each provision of a

contract must be supported by consideration expressed in that provision. If so, then

Plaintiffs’ “illusory” argument could apply to the arbitration agreement alone and this

court would not be precluded by Prima Paint from addressing the argument. Plaintiffs

have not shown, however, that in either state the relevant general contract law requires a

different result. We first address Arizona before turning to Louisiana.

       At first blush, Arizona law may appear to be nonstandard. An Arizona appellate

decision states that an arbitration clause must be supported by consideration independent

of the consideration supporting the contract as a whole. See Stevens/Leinweber/Sullens,

Inc. v. Holm Dev. & Mgmt., Inc., 

, 1313 (Ariz. Ct. App. 1990)

(“Because . . . the arbitration provision is an independent and separate agreement, [the

defendant] cannot ‘borrow’ consideration from the principal contract to support the

arbitration provision.”). But that opinion does not purport to state a general rule of

contract law, only a rule applicable to arbitration clauses. (It appears to have relied on a

misreading of Prima Paint, but the source of its ruling is irrelevant for our purposes.)

Such arbitration-specific law is not the sort of general state law applicable under 9 U.S.C.

§ 2 of the FAA. As stated in Perry:

       A state-law principle that takes its meaning precisely from the fact that a
       contract to arbitrate is at issue does not comport with . . . § 2. A court may
       not . . . in assessing the rights of litigants to enforce an arbitration
       agreement, construe that agreement in a manner different from that in
       which it otherwise construes nonarbitration agreements under state law.


                                              28
       Nor may a court rely on the uniqueness of an agreement to arbitrate as a
       basis for a state-law holding that enforcement would be unconscionable, for
       this would enable the court to effect what we hold today the state
       legislature 

n.9 (citations omitted); see Doctor’s Assocs., Inc. v. Casarotto, 

, 687 (1996) (“Congress precluded States from singling out arbitration provisions for

suspect status, requiring instead that such provisions be placed upon the same footing as

other contracts.”); Southland Corp. v. Keating, 

, 16 n.11 (1984) (rejecting

application of California Franchise Investment Law that barred enforcement of an

arbitration agreement because the statute is “not a ground that exists at law or in equity

‘for the revocation of any contract’ but merely a ground that exists for the revocation of

arbitration provisions”). Thus, a federal district court in Arizona correctly refused to

follow Stevens. In Diversified Roofing Corp. v. Pulte Home Corp., No. CV12-1880 PHX

DGC, 

, at *4 (D. Ariz. Dec. 19, 2012), the plaintiff argued that

Arizona law required separate consideration to support an arbitration clause. But the

court held that Stevens was inapplicable “because the FAA applies state law only to the

extent that it is not hostile to arbitration.”

  Feldman’s reliance on Coup v. Scottsdale Plaza Resort, LLC, 

, 950
(D. Ariz. 2011), is misplaced. In that case the magistrate judge ordered arbitration. See

And the court recognized that “so long as a contract is supported by sufficient
consideration there is no requirement of equivalent promises or mutuality of obligation.”

(internal quotation marks omitted). It cited Stevens only for the proposition
that Arizona will ordinarily follow the Restatement (Second) of Contracts; and we are not
persuaded by any dictum in the opinion that might be read to adopt Stevens’ departure
from the Restatement as a matter of general contract law.

                                              29
       As for Louisiana, it follows civil law, see Duckworth v. La. Farm Bureau Mut. Ins.

Co., 

, 1064 (La. 2012), which does not incorporate the notion of

consideration, see Aaron & Turner, L.L.C. v. Perret, 

, 915 (La. Ct. App.

2009) (“Louisiana does not follow the common law tradition that requires consideration

to effect an enforceable contract. Rather, the mere will of the parties will bind them,

without what a common law court would consider to be consideration to support a

contract, so long as the parties have a lawful ‘cause.’”). Alwert nevertheless relies on

Simpson v. Grimes, 

(La. Ct. App. 2003), to argue that the arbitration

clause is unenforceable. The plaintiffs in Simpson sued to recover losses to an individual

retirement account (IRA) based on an alleged breach of fiduciary duty, among other

claims. See 

The defendants invoked the arbitration clause in the IRA

application. See 

court of appeals held that it was unenforceable because the

defendants had retained the unilateral right to modify the agreement and thereby created

an “escape hatch” from its promise to be bound to arbitrate disputes. 

The

court concluded that the defendants’ right to modify resulted in a lack of mutuality,

rendering the agreement unconscionable and unenforceable. See 

       But to the extent that Simpson held that a unilateral right to modify made an

arbitration clause unenforceable, it was subsequently overruled by the Louisiana Supreme

Court in Aguillard v. Auction Mgmt. Corp., 

(La. 2005), which granted

certiorari to resolve a split in Louisiana’s lower courts (specifically mentioning Simpson)

“regarding the enforceability of arbitration agreements in consumer standard form

contracts under a ‘contract of adhesion’ analysis,” 

The Aguillard plaintiff


                                             30
entered into a contract with an auctioneer that provided the auction’s terms and

conditions. See 

The contract contained an arbitration clause as well as a

provision stating that “[a]ll announcements from the Auction Block will take precedence

over all previously printed materials and other oral statements made.” 

of

appeals had held that this provision gave the auctioneer “the unilateral power to change

any or all parts of the contract, including the arbitration clause, simply by verbal

announcement at the auction block,” making the arbitration clause unenforceable because

it was adhesionary and lacking in mutuality. 

But the Louisiana Supreme Court

held that the arbitration clause was enforceable. See 

We need not review the

particulars of Louisiana law on which the court relied. The essential point is that the

unilateral power to revise the contract did not make the arbitration provisions

unenforceable.

       Plaintiffs argue that “[t]here is no indication in Aguillard that the Louisiana

Supreme Court would validate an arbitration provision that truly lacked mutuality

because one party maintained the unilateral right to modify it at will.” Aplt. Br. at 21 n.6.

But to the contrary, the Aguillard court recognized that the contract provided the

defendant with a unilateral right to modify it via announcements from the auction block.

(“the terms . . . provided the defendants with the right to make

announcements from the Auction Block that would take precedence over all previously

printed materials”). Perhaps the court left open the possibility that an arbitration

provision in a contract containing a clause giving one party the unilateral right to modify

could be unenforceable if there are other circumstances that would indicate


                                             31
unconscionability. See 

rather than confronting Aguillard’s holding and

trying to distinguish the facts here, simply misstate that holding. Because the issue was

not briefed, we need not address whether such other circumstances are present here. See

      III.    CONCLUSION

       We AFFIRM the district court’s orders compelling arbitration.
