Judge LEVAL concurs in a separate opinion.
DENNIS JACOBS, Circuit Judge:
This antitrust class action was brought on behalf of approximately 12 million merchants against Visa U.S.A. Inc. (‘Visa”) and MasterCard International Incorporated (“MasterCard”), which are the two largest credit card issuing networks in the United States, as well as against various issuing and acquiring banks (collectively with Visa and MasterCard, the “defendants”), alleging a conspiracy in violation of Section 1 of the Sherman Act. After nearly ten years of litigation, the parties agreed to a settlement that released all claims in exchange for disparate relief for each of two classes: up to $7.25 billion would go to an opt-out class, and a non-opt-out class would get injunctive relief. The district court certified these two settlement-only classes, and approved the settlement as fair and reasonable. On this appeal, numerous objectors and opt-out plaintiffs argue that this class action was improperly certified and that the settlement was unreasonable and inadequate. We conclude that the class plaintiffs were inadequately represented in violation of Rule 23(a)(4) and the Due Process Clause. Accordingly, we vacate the district court’s certification of this class action and reverse the approval of the settlement.
BACKGROUND
Detailed information about how the credit card industry operates is set out in [228]*228the district court opinion approving • the settlement in this case, In re Payment Card Interchange Fee and Merchant Discount Antitrust Litig. (“Payment Card I”), 986 F.Supp.2d 207, 214-15 (E.D.N.Y. 2013), and in our previous opinions dealing with past antitrust lawsuits against Visa and MasterCard, Wal-Mart Stores, Inc. v. Visa U.S.A., Inc., 396 F.3d 96, 101-02 (2d Cir. 2005); United States v. Visa U.S.A., Inc., 344 F.3d 229, 234-37 (2d Cir. 2003); In re Visa Check/MasterMoney Antitrust Litig. (“Visa Check”), 280 F.3d 124, 129-31 (2d Cir. 2001). This section of the opinion lays out only the facts and procedural history needed to explain our analysis and result.
In general terms, a Visa or MasterCard credit card transaction is processed as follows: the customer presents a credit card to pay for goods or services to the merchant; the merchant relays the transaction information to the acquiring bank; the. acquiring bank processes the information and relays it to the network (here, Visa or MasterCard); the network relays the information to the issuing bank; if the issuing bank approves the transaction, that approval is relayed to the acquiring bank, which then relays it to the merchant. If the transaction is approved, the merchant receives the purchase price minus two fees: the “interchange fee” that the issuing bank charged the acquiring bank and the “merchant discount fee” that the acquiring bank charged the merchant.
In a given transaction, the interchange fee that the acquiring bank pays (and is in turn paid by the merchant) varies depending on the credit card network and the type of credit card. Thus, the American Express credit-card network generally charges a higher interchange fee than the Visa or MasterCard networks. And Visa and MasterCard have different product levels within their credit card portfolios, such as cards that give consumers generous rewards, and typically charge a higher interchange fee than cards that offer few rewards or none. The difference in interchange fee between American Express and Visa or MasterCard is one at the brand level, while the difference between, e.g., a rewards card from Visa and a no-rewards card from Visa is one at the product level.
Plaintiffs are all merchants who accept Visa- and MasterCard-branded credit cards and are therefore bound by the issuers’ network rules. Plaintiffs challenge as anti-competitive several of the following ■ network rules (which are effectively identical as between Visa and MasterCard). The “default interchange” fee applies to every transaction on the network (unless the merchant and issuing bank have entered into a separate agreement). The “honor-all-cards” rule requires merchants to accept all Visa or MasterCard credit cards if they accept any of them, regardless of the differences in interchange fees. Multiple rules prohibit merchants from influencing customers to use one type of payment over another, such as cash rather than credit, or a credit card with a lower interchange fee. These “anti-steering” rules include the “no-surcharge” and “no-discount” rules, which prohibit merchants from charging different prices at the point of sale depending on the means of payment.
Plaintiffs allege that these Visa and MasterCard network rules, working in tandem, allow the issuing banks to impose an artificially inflated interchange fee that merchants have little choice but to accept. The argument is that the honor-all-cards rule forces merchants to accept all Visa and MasterCard credit cards (few merchants can afford to accept none of them); the anti-steering rules prohibit them from nudging consumers toward cheaper forms of payment; the issuing banks are thus free to set interchange fees at a supra-[229]*229competitive rate; and that rate is effectively locked in via the default interchange fee because the issuing banks have little incentive to deviate from it unless a given merchant is huge enough to have substantial bargaining power.
The first consolidated complaint in this action was filed in 2006. Developments since then have altered the credit card industry in important ways. Both Visa and MasterCard conducted initial public offerings that converted each from a consortium of competitor banks into an independent, publicly traded company. The “Durbin Amendment” to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 limited the interchange fee that issuing banks could charge for debit card purchases, and allowed merchants to discount debit card purchases relative to credit card purchases. Finally, pursuant to a consent decree with the Department of Justice in 2011, Visa and MasterCard agreed to permit merchants to discount transactions to steer consumers away from credit cards use. None of these developments affected the honor-all-cards or no-surcharging rules, or the existence of a default interchange fee.
Notwithstanding these pro-merchant industry developments, the plaintiffs pressed on. Discovery included more than 400 depositions, 17 expert reports, 32 days of expert deposition testimony, and the production of over 80 million pages of documents. The parties fully briefed a motion for class certification, a motion to dismiss supplemental complaints, and cross-motions for summary judgment. Beginning in 2008, the parties participated in concurrent settlement negotiations assisted by well-respected mediators. At the end of 2011, the district judge and the magistrate judge participated in the parties’ discussions with the mediators. In October 2012, after several more marathon negotiations with the mediators (including one more with the district court and magistrate judges), the parties executed the Settlement Agreement. The district court granted preliminary approval of the proposed settlement on November 27, 2012, and final approval on December 13, 2013. Payment Card I, 986 F.Supp.2d at 213, 217.
The Settlement Agreement divides the plaintiffs into two classes: one — the Rule 23(b)(3) class — covers merchants that accepted Visa and/or MasterCard from January 1, 2004 to November 28, 2012; the other — the Rule 23(b)(2) class — covers merchants that accepted (or will accept) Visa and/or MasterCard from November 28, 2012 onwards forever. The former class would be eligible to receive up to $7.25 billion in monetary relief; the latter would get injunctive relief in the form of changes to Visa’s and MasterCard’s network rules. Because of the difference between Rule 23(b)(3) and Rule 23(b)(2), members of the first class (which receives money damages in the settlement) could opt out, but members of the second, forward-looking class (which receives only injunctive relief) could not.
The most consequential relief afforded the (b)(2) class was the ability to surcharge Visa- and MasterCard-branded credit cards at both the brand and product levels. That is, a merchant could increase the price of a good at the point of sale if a consumer presents (for example) a Visa card instead of cash, or a Visa rewards card instead of a Visa card that yields no rewards. The incremental value and utility of this relief is limited, however, because many states, including New York, California, and Texas, prohibit surcharging as a matter of state law. See, e.g., Expressions Hair Design v. Schneiderman, 808 F.3d 118, 127 (2d Cir. 2015) (upholding the New York ban on credit-card surcharges); Ro-[230]*230well v. Pettijohn, 816 F.3d 73, 80 (5th Cir. 2016) (upholding the Texas ban on credit-card surcharges). But see Dana’s R.R. Supply v. Attorney Gen., Florida, 807 F.3d 1235, 1249 (11th Cir. 2015) (striking down Florida ban on credit-card surcharges). Moreover, under the most-favored-nation clause included in the Settlement Agreement, merchants that accept American Express cannot avail themselves of the surcharging relief because American Express effectively prohibits surcharging, and the Settlement Agreement permits surcharging for Visa or MasterCard only if the merchant also surcharges for use of cards issued by competitors such as American Express.
Visa and MasterCard also agreed to modify their network rules to reflect that they will: negotiate interchange fees with groups of merchants in good faith, lock-in the benefits of the Durbin Amendment and Department of Justice consent decree, and permit a merchant that operates multiple businesses under different names or banners to accept Visa or MasterCard at fewer than all of its businesses.
The Settlement Agreement provides that all of the injunctive relief will terminate on July 20, 2021.
In return, the plaintiffs are bound by a release that waives any claims they would have against the defendants for: all of the conduct challenged in the operative complaint, all other policies and practices (concerning credit card transactions) that were in place as of November 27, 2012, and any substantially similar practices they adopt in the future. While the injunctive relief for the (b)(2) class will expire on July 20, 2021, this release has no end date. It operates in perpetuity, provided only that Visa and MasterCard keep in place the several rules that were modified by the injunctive relief provided to the (b)(2) class (including, inter alia, permitting merchants to surcharge), or impose rules that are substantially similar to the modified rules. That is, after July 20, 2021, for as long as Visa and MasterCard elect to leave in place their network rules as modified by the Settlement Agreement or adopt rules substantially similar thereto, the defendants continue to enjoy the benefit of the release as to all claims the plaintiffs potentially had against the defendants for any of the network rules existing as of November 27, 2012.
If, after July 20, 2021, the Visa or MasterCard networks rules are changed such that they are no longer substantially similar to their form as modified by the Settlement Agreement, then merchants are freed from the release as to claims arising out of that new network rule — but only as to such claims. For example, if Visa or MasterCard revert to their pre-Settlement Agreement rules by forbidding merchants from surcharging, then the release will not bar future merchants included in the (b)(2) class from bringing antitrust claims arising out of the prohibition on surcharging; but the rest of release would remain in effect, so that a suit by the future plaintiff could not challenge any of the unchanged network rules, such as the honor-all-cards rule or imposition of default interchange fees. In sum, regardless what Visa or MasterCard do with their network rules after July 20, 2021, no merchant will ever be permitted to bring claims arising out of the network rules that are unaffected by this Settlement Agreement, including most importantly, the honor-all-cards rule or existence of default interchange fees.
Appellants, including those that opted out from the (b)(3) class and objected to the (b)(2) class, argue that the (b)(2) class was improperly certified and that the settlement was inadequate and unreasonable.
[231]*231DISCUSSION
Certification of a class is reviewed for abuse of discretion, be., whether the decision (i) rests on a legal error or clearly erroneous factual finding, or (ii) falls outside the range of permissible decisions. In re Literary Works in Elec. Databases Copyright Litig. (“Literary Works”), 654 F.3d 242, 249 (2d Cir. 2011). The district court’s factual findings are reviewed for clear error; its conclusions of law are reviewed de novo. Charron v. Wiener, 731 F.3d 241, 247 (2d Cir. 2013).
Class actions are an exception to the rule that only the named parties conduct and are bound by litigation. See Hansberry v. Lee, 311 U.S. 32, 40-41, 61 S.Ct. 115, 85 L.Ed. 22 (1940). “In order to justify a departure from that rule, a class representative must be part of the class and possess the same interest and suffer the same injury as the class members.” Wal-Mart v. Dukes, 564 U.S. 338, 131 S.Ct. 2541, 2550, 180 L.Ed.2d 374 (2011) (internal quotation marks and citations omitted). That principle is secured by Rule 23(a)(4) and the Due Process Clause. Rule 23(a)(4), which requires that “the representative parties ... fairly and adequately protect the interests of the class,” “serves to uncover conflicts of interest between named parties and the class they seek to represent,” as well as the “competency and conflicts of class counsel.” Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 625, 626 n. 20, 117 S.Ct. 2231, 138 L.Ed.2d 689 (1997). “[T]he Due Process Clause of course requires that the named plaintiff at all times adequately represent the interests of the absent class members.” Phillips Petroleum Co. v. Shutts, 472 U.S. 797, 812, 105 S.Ct. 2965, 86 L.Ed.2d 628 (1985). Class actions and settlements that do not comply with Rule 23(a)(4) and the Due Process Clause cannot be sustained.
We conclude that class members of the (b)(2) class were inadequately represented in violation of both Rule 23(a)(4) and the Due Process Clause. Procedural deficiencies produced substantive shortcomings in this class action and the settlement. As a result, this class action was improperly certified and the settlement was unreasonable and inadequate.
I
Under Rule 23(a)(4), “[a]dequacy is twofold: the proposed class representative must have an interest in vigorously pursuing the claims of the class, and must have no interests antagonistic to the interests of other class members.” Denney v. Deutsche Bank AG, 443 F.3d 253, 268 (2d Cir. 2006); see also Robinson v. Metro-North Commuter R.R. Co., 267 F.3d 147, 170 (2d Cir. 2001) (“Two factors generally inform whether class representatives satisfy the Rule 23(a)(4) requirement: ‘(1) absence of conflict and (2) assurance of vigorous prosecution.’ ”) To assure vigorous prosecution, courts consider whether the class representative has adequate incentive to pursue the class’s claim, and whether some difference between the class representative and some class members might undermine that incentive. Id. at 171. To avoid antagonistic interests, any “fundamental” conflict that goes “to the very heart of the litigation,” Charron, 731 F.3d at 249-50 (internal citations omitted), must be addressed with a “structural assurance of fair and adequate representation for the diverse groups and individuals” among the plaintiffs. Amchem, 521 U.S. at 627, 117 S.Ct. 2231. One common structural protection is division of the class into “homogenous subclasses under Rule 23(c)(4)(B), with separate representation to eliminate conflicting interests of counsel.” Ortiz v. Fibreboard Corp., 527 U.S. 815, 856, 119 S.Ct. 2295, 144 L.Ed.2d 715 (1999).
[232]*232“Adequacy must be determined independently of the general fairness review of the settlement; the fact that the settlement may have overall benefits for all class members is not the ‘focus’ in ‘the determination whether proposed classes are sufficiently cohesive to warrant adjudication.’ ” Denney, 443 F.3d at 268 (quoting Ortiz, 527 U.S. at 858, 119 S.Ct. 2295). The focus of the Rule 23(a) inquiry remains on “inequity and potential inequity at the pre-certification stage.” Ortiz, 527 U.S. at 858, 119 S.Ct. 2295. So when (as here) the district court certifies the class at the same time it approves a settlement, the requirements of Rule 23(a) “demand undiluted, even heightened, attention.” Am-chem, 521 U.S. at 620, 117 S.Ct. 2231.
A
The Supreme Court wrote the ground rules for adequate representation in the settlement-only class context in Amchem and Ortiz, two asbestos cases. Our recent decision in Literary Works contributed a gloss on the subject.
The single-class proposed settlement in Amchem potentially encompassed millions of plaintiffs who had been exposed to asbestos, without distinction between those who had already manifested asbestos-related injuries and sought “generous immediate payments,” and those who had not manifested injury and sought “an ample, inflation-protected fund for the future.” Amchem, 521 U.S. at 626, 117 S.Ct. 2231. A single class representative could not adequately represent both interests. The two subgroups had “competing interests in the distribution of a settlement whose terms reflected ‘essential allocation decisions designed to confine compensation and to limit defendants’ liability.’ ” Literary Works, 654 F.3d at 250 (quoting Amchem, 521 U.S. at 627, 117 S.Ct. 2231). The antagonistic interests were so pronounced, on an issue so crucial, that the settlement required a “structural assurance of fair and adequate representation for the diverse groups and individuals.” Amchem, 521 U.S. at 627,117 S.Ct. 2231.
Two years later, the Supreme Court again considered a settlement-only class action that joined present and future claimants in a single class, and emphasized: “it is obvious after Amchem that a class divided between holders of present and future claims ... requires division into homogenous subclasses under Rule 23(c)(4)(B), with separate representation to eliminate conflicting interests of counsel.” Ortiz, 527 U.S. at 856, 119 S.Ct. 2295. A second fatal deficiency in the Ortiz settlement was that all present claimants were treated equally, notwithstanding that some had claims that were more valuable. “It is no answer to say ... that these conflicts may be ignored because the settlement makes no disparate allocation of resources as between the conflicting classes” for the “very decision to treat them all the same is itself an allocation decision with results almost certainly different from the results that [the disparate claimants] would have chosen.” Id. at 857, 119 S.Ct. 2295. These fault lines between present and future plaintiffs, and among plaintiffs with differently valued claims, were so fundamental that they required “structural protection” in the form of subclasses with separate counsel. Id-
Literary Works contained the same “ingredients of conflict identified in Amchem and Ortiz.” Literary Works, 654 F.3d at 251. The settlement divided class claims into three categories, capped defendants’ overall liability at $18 million, and used a formula for splitting this amount. The settlement was less generous to the third category, and required the holders of those claims to exclusively bear the risk of over-subscription, he., their recovery alone [233]*233would be reduced to bring the total payout down to $18 million. The class representatives of the single class included individuals with claims in each category; nevertheless, we held that (at a minimum) class members with claims only in the third category required separate representation because their interests were antagonistic to the others on a matter of critical importance — how the money would be distributed. Id. at 254.
Since some named representatives held claims across all three categories, the class did not encompass mutually exclusive groups as in Amchem; still, each imper-missibly “served generally as representative for the whole, not for a separate constituency.” Id. at 251 (quoting Amchem, 521 U.S. at 627, 117 S.Ct. 2231). Class representatives with claims in all three categories naturally would want to maximize their overall recovery regardless of allotment across categories, whereas class members with claims only in the third category would want to maximize the compensation for that category in particular. A great risk thus arose that class representatives would sell out the third category of claims for terms that would tilt toward the others. As it transpired, the resulting settlement awarded the third category less, and taxed that lesser recovery with all the risk that claim would exceed the liability cap.
We did not conclude that the third category’s “inferior recovery [w]as determinative evidence of inadequate representation.” Id. at 253. The claims in third category were objectively the weakest. “The problem, of course, [wa]s that we ha[d] no basis for assessing whether the discount applied to Category C’s recovery appropriately reflected] that weakness.” Id. We could not know the right value of the category C claims “without independent counsel pressing its most compelling case.” Id. While the settlement “was the product of an intense, protected, adversarial mediation, involving multiple parties,” including “highly respected and capable” mediators and associational plaintiffs, these features of the negotiation could not “compensate for the absence of independent representation” because there could be no assurance that anyone “advanced the strongest arguments in favor” of the disfavored claims. Id. at 252-53. The eventual settlement proved that “[o]nly the creation of subclasses, and the advocacy of an attorney representing each subclass, can ensure that the interests of that particular subgroup are in fact adequately represented.” Id. at 252. Divided loyalties are rarely divided down the middle.
B
Like the settlement-only classes in Amchem, Ortiz, and Literary Works, the unitary representation of these plaintiffs was inadequate. Class representatives had interests antagonistic to those of some of the class members they were representing. The fault lines were glaring as to matters of fundamental importance. Such conflicts and absence of incentive required a sufficient “structural assurance of fair and adequate representation,” Amchem, 521 U.S. at 627, 117 S.Ct. 2231, but none was provided.
The conflict is clear between merchants of the (b)(3) class, which are pursuing solely monetary relief, and merchants in the (b)(2) class, defined as those seeking only injunctive relief. The former would want to maximize cash compensation for past harm, and the latter would want to maximize restraints on network rules to prevent harm in the future. Amchem tells us that such divergent interests require separate counsel when it impacts the “essential allocation decisions” of plaintiffs’ compensa[234]*234tion and defendants’ liability. Amchem, 521 U.S. at 627,117 S.Ct. 2231. The Settlement Agreement does manifest tension on an “essential allocation decision”: merchants in the (b)(3) class would share in up to $7.25 billion of damages, while merchants in the (b)(2) class would enjoy the benefit of some temporary changes to the defendants’' network rules. The same counsel represented both the (b)(3) and the (b)(2) classes. The class counsel and class representatives who negotiated and entered into the Settlement Agreement were in the position to trade diminution of (b)(2) relief for increase of (b)(3) relief. However, “it is obvious after Amchem that a class divided between holders of present and future claims ... requires division into homogenous subclasses ... with separate representation.” Ortiz, 527 U.S. at 856,119 S.Ct. 2295.
Moreover, many members of the (b)(3) class have little to no interest in the efficacy of the injunctive relief because they no longer operate, or no longer accept Visa or MasterCard, or have declining credit card sales. By the same token, many members of the (b)(2) class have little to no interest in the size of the damages award because they did not operate or accept Visa or MasterCard before November 28, 2012, or have growing credit card sales. Unitary representation of separate classes that claim distinct, competing, and conflicting relief create unacceptable incentives for counsel to trade benefits to one class for benefits to the other in order somehow to reach a settlement.
Class counsel stood to gain enormously if they got the deal done. The (up to) $7.25 billion in relief for the (b)(3) class was the “largest-ever cash settlement in an antitrust class action.” Payment Card I, 986 F.Supp.2d at 229. For their services, the district court granted class counsel $544.8 million in fees. In re Payment Card Interchange Fee and Merchant Discount Antitrust Litig. (“Payment Card II”), 991 F.Supp.2d 437, 440 (E.D.N.Y. 2014). The district court calculated these fees based on a graduated percentage cut of the (b)(3) class’s recovery; thus counsel got more money for each additional dollar they secured for the (b)(3) class. But the district court’s calculation of fees explicitly did not rely on any benefit that would accrue to the (b)(2) class, id. at 442 n. 4, and class counsel did not even ask to be compensated based on the size or significance of the injunctive relief. Id. The resulting dynamic is the same as in Ortiz. As the Supreme Court recognized in that case: when “the potential for gigantic fees” is within counsel’s grasp for representation of one group of plaintiffs, but only if counsel resolves another group of plaintiffs’ claims, a court cannot assume class counsel adequately represented the latter group’s interests. Ortiz, 527 U.S. at 852, 119 S.Ct. 2295. We expressly do not impugn the motives or acts of class counsel. Nonetheless, class counsel was charged with an inequitable task.
The trouble with unitary representation here is exacerbated because the members of the worse-off (b)(2) class could not opt out. The (b)(2) merchants are stuck with this deal and this representation. We do not decide whether providing these class members with opt out rights would be a sufficient “structural assurance of fair and adequate representation,” Amchem, 521 U.S. at 627, 117 S.Ct. 2231, to overcome the lack of separate class counsel and representative. Cf. Visa Check, 280 F.3d at 147. It is enough to say that this feature of the Settlement Agreement compounded the problem.
One aspect of the Settlement Agreement that emphatically cannot remedy the inadequate representation is the assistance of judges and mediators in the [235]*235bargaining process. True, “a court-appointed mediator’s involvement in pre-cer-tification settlement negotiations helps to ensure that the proceedings were free of collusion and undue pressure.” D’Amato v. Deutsche Bank, 236 F.3d 78, 85 (2d Cir. 2001). But even “an intense, protected, adversarial mediation, involving multiple parties,” including “highly respected and capable” mediators and associational plaintiffs, does not “compensate for the absence of independent representation.” Literary Works, 654 F.3d at 252-53. The mission of mediators is to bring together the parties and interests that come to them. It is not their role to advance the strongest arguments in favor of each subset of class members entitled to separate representation, or to voice the interests of a group for which no one else is speaking.
Nor is the problem cured by the partial overlap of merchants who get cash as members of the (b)(3) class and become members of the (b)(2) class as they continue to accept Visa or MasterCard. The force of Amchem and Ortiz does not depend on the mutually exclusivity of the classes; it was enough that the classes did not perfectly overlap. We held as much in Literary Works, reasoning that named plaintiffs with claims in multiple subgroups cannot adequately represent the interests of any one subgroup because their incentive is to maximize their own total recovery, rather than the recovery for any single subgroup. Amchem observed that “where differences among members of a class are such that subclasses must be established, we know of no authority that permits a court to approve a settlement ... on the basis of consents by members of a unitary class, some of whom happen to be members of the distinct subgroups.” Amchem, 521 U.S. at 627, 117 S.Ct. 2231 (quoting In re Joint E. and S. Dist. Asbestos Litig., 982 F.2d 721, 742-43 (2d Cir. 1992), modified on reh’g, 993 F.2d 7 (2d Cir. 1993)).
Moreover, whatever overlap presently exists is partial and shrinking with time. As of the September 12, 2013 fairness hearing, class counsel reported that the class was composed of about 12 million merchants. That figure of course does not include merchants that have come into being since then, or those that will come into being in the future, all of whom will be members of only the (b)(2) class. The membership of the (b)(3) class, on the other hand, is fixed and finite. Over time, the initial overlap will be reduced, and the gap between the interests of the (b)(3) and (b)(2) classes will continue to widen.
None of this is to say that (b)(3) and (b)(2) classes cannot be combined in a single case, or that (b)(3) and (b)(2) classes necessarily and always require separate representation. Problems arise when the (b)(2) and (b)(3) classes do not have independent counsel, seek distinct relief, have non-overlapping membership, and (importantly) are certified as settlement-only. The requirements of Rule 23(a) are applied with added solicitude in the settlement-only class context because “the certification of a mandatory settlement class ‘effectively concludes the proceeding save for the final fairness hearing,’ and there is thus a heightened risk of conflating the fairness requirements of Rule 23(e) with the independent requirement of ‘rigorous adherence to those provisions of the Rule designed to protect absentees,’ such as Rules 23(a) and (b).” Charron, 731 F.3d at 250 (quoting Ortiz, 527 U.S. at 849, 119 S.Ct. 2295). As in Amchem, Ortiz, and Literary' Works, settlements that are approved simultaneously with class certification are especially vulnerable to conflicts of interest because the imperatives of the settlement process, which come to bear on the defendants, the class counsel, and even [236]*236the mediators and the court itself, can influence the definition of the classes and the allocation of relief. For this reason, we scrutinize such settlements more closely.
Of course we have blessed multi-class settlements that were the product of unitary representation, but those were entered into after class certification. For example, we approved a settlement negotiated by unitary counsel in Charron; but before doing so, we “note[d] that unlike the situation in Amchem, Ortiz, and Literary Works, the settlement here was not being approved at the same time that the class was being certified.” Charron, 731 F.3d at 250. Accordingly, we were more skeptical of allegations that subclass conflicts required separate representation. Id. True, Charron observed “[a]ll class settlements value some claims more highly than others, based on their perceived merits, and strike compromises based on probabilistic assessments,” id. but that observation has less force in the settlement-only context. Charron also spoke of counsel trading one claim for another (which may be permissible); in the settlement-only class action, we are concerned that counsel will trade the interests of one class for another (which is not).
We have reason to think that that occurred here. Structural defects in this class action created a fundamental conflict between the (b)(3) and (b)(2) classes and sapped class counsel of the incentive to zealously represent the latter. Apparently, the only unified interests served by herding these competing claims into one class are the interests served by settlement:' (i) the interest of class counsel in fees, and (ii) the interest of defendants in a bundled group of all possible claimants who can be precluded by a single payment. This latter interest highlights the next problem with the Settlement Agreement.
II
This opinion already concludes that class plaintiffs were inadequately represented. Accordingly, the settlement and release that resulted from this representation are nullities. See Stephenson v. Dow Chem. Co., 273 F.3d 249, 260 (2d Cir. 2001), aff'd in part by an equally divided court and vacated in part, 539 U.S. Ill, 123 S.Ct. 2161, 156 L.Ed.2d 106 (2003) (“Res judica-ta generally applies to bind absent class members except where to do so would violate due process” and “[d]ue process requires adequate representation at all times throughout the litigation.”). This outcome is confirmed by the substance of the deal that was struck. Like the Supreme Court in Amchem, we “examine a settlement’s substance for evidence of prejudice to the interests of a subset of plaintiffs” when “assessing the adequacy of representation.” Literary Works, 654 F.3d at 252. Here, the bargain that was struck between relief and release on behalf of absent class members is so unreasonable that it evidences inadequate representation.
“It is familiar doctrine of the federal courts that members of a class not present as parties to the litigation may be bound by the judgment where they are in fact adequately represented by parties who are present” consistent with “the requirements of due process and full faith and credit.” Hansberry, 311 U.S. at 42-43, 61 S.Ct. 115 (emphasis added); see also Stephenson, 273 F.3d at 261 (“Part of the due process inquiry (and part of the Rule 23(a) class certification requirements) involves assessing adequacy of representation and intra-class conflicts.”). Similarly, “[p]lain-tiffs in a class action may release claims that were or could have been pled in exchange for settlement relief’; but this authority “is limited by the ‘identical factual predicate’ and ‘adequacy of representation’ [237]*237doctrines.” Wal-Mart Stores, 396 F.3d at 106. “[W]here class plaintiffs have not adequately represented the interests of class members,” any “[c]laims arising from a shared set of facts will not be precluded.” Id. at 108.
As discussed above, Literary Works concluded that inadequate representation was demonstrated by the relief afforded to a subset of the class. Similarly, the release in Stephenson was itself proof of inadequate representation, wheras the release in Wal-Mart Stores did not impugn the class’s representation. Considered together, these cases illustrate when the tradeoff between relief and release as applied to a class member can violate due process.
Literary Works held that class members with claims in one of the categories were inadequately represented not only because they did not receive separate representation, but also because they solely bore the risk that the total amount claimed would exceed a preset liability cap. We observed that this feature of the settlement could not be justified by the relative weakness of those claims because that fact was already accounted for. Literary Works, 654 F.3d at 253. We could discern no reason for subjecting the single category of claims to the whole risk of over-subscription; nor could the settlement’s proponents. Id. at 254. When “one category [of class members are] targeted for [worse treatment] without credible justification” it “strongly suggests a lack of adequate representation for those class members who hold only claims in this category.” Id.
In Stephenson, we considered a collateral attack on a class action that had established a settlement fund for individuals injured by exposure to Agent Orange. The underlying litigation provided compensation only for those who discovered their injury before 1994, yet released all future claims. Two individuals who fell within the class definition of individuals injured by Agent Orange, but who learned of their injury after 1994, challenged the release as applied to them. Analogizing the case to Amchem and Ortiz, we concluded that the two individuals were inadequately represented in the prior litigation because the settlement purported to resolve all future claims but “the settlement fund was permitted to terminate in 1994” and “[n]o provision was made for post-1994 claimants.” Stephenson, 273 F.3d at 260-61. The two challengers could not have been adequately represented if their class representative negotiated a settlement and release that extinguished their claims without affording them any recovery. The result violated due process; the plaintiffs could not be bound by the settlement release. Id. at 261.
A similar challenge was raised to the settlement release in Wal-Mart Stores, which foreclosed all claims arising from the same factual predicate as that alleged in the complaint. Objectors argued that they were inadequately represented because class representatives did not pursue certain claims as vigorously as others. We rejected this basis for objection because “adequate representation of a particular claim is determined by the alignment of interests of class members, not proof of vigorous pursuit of that claim.” Wal-Mart Stores, 396 F.3d at 113. Stephenson was “not directly on point” because in the Agent Orange settlement (as in the Am-chem and Ortiz settlements) “future claims had not been considered separately from claims involving current injury” despite these two groups having clearly divergent interests. Id. at 110. The objectors in Wal-Mart Stores did not allege divergent interests; they had disagreements about which claims were most valuable and what relief [238]*238was adequate. Moreover, the settlement in Wal-Mart Stores covered only a past, finite period and did not preclude future suits over conduct post-dating the settlement. Id. No future claimants or claims were covered by the Wal-Mart Stores settlement or release. Finally, every claimant from the objecting groups benefitted from the settlement. Id. at 112.
Merchants in the (b)(2) class that accept American Express or operate in states that prohibit surcharging gain no appreciable benefit from the settlement, and merchants that begin business after July 20, 2021 gain no benefit at all. In exchange, class counsel forced these merchants to release virtually any claims they would ever have against the defendants. Those class members that effectively cannot surcharge and those that begin operation after July 20, 2021 were thus denied due process.
No one disputes that the most valuable relief the Settlement Agreement secures for the (b)(2) class is the ability to surcharge at the point of sale. To the extent that the injunctive relief has any meaningful value, it comes from surcharging, not from the buying-group provision, or the all-outlets provision, or the locking-in of the Durbin Amendment and DOJ consent decree. For this reason, it is imperative that the (b)(2) class in fact benefit from the right to surcharge. But that relief is less valuable for any merchant that operates in New York, California, or Texas (among other states that ban surcharging), or accepts American Express (whose network rules prohibit surcharging and include a most-favored nation clause). Merchants in New York and merchants that accept American Express can get no advantage from the principal relief their counsel bargained for them.
It may be argued that the claims of the (b)(2) class are weak and can command no benefit in settlement. However, that argument would seem to be foreclosed because other members of the same class with the same claims — those that do not take American Express and operate in states that permit surcharging — derive a potentially substantial benefit. There is no basis for this unequal intra-class treatment: the more valuable the right to surcharge (a point the parties vigorously dispute), the more unfair the treatment of merchants that cannot avail themselves of surcharging.
This is not a case of some plaintiffs forgoing settlement relief. A significant proportion of merchants in the (b)(2) class are either legally or commercially unable to obtain incremental benefit from the primary relief negotiated for them by their counsel, and class counsel knew at the time the Settlement Agreement was entered into that this relief was virtually worthless to vast numbers of class members. Alternative forms of relief might have conferred a real and palpable benefit, such as remedies that affected the default interchange fee or honor-all-cards rule. This is not a matter of certain merchants (e.g., those based in New York and those that accept American Express) arguing that class counsel did not bargain for their preferred form of relief, did not press certain claims more forcefully, or did not seek certain changes to the network rule books more zealously. This is a matter of class counsel trading the claims of many merchants for relief they cannot use: they actually received nothing.
Another fault line within the (b)(2) class runs between merchants that will have accepted Visa or MasterCard before July 20, 2021, and those that will come into being thereafter. The former are at least guaranteed some form of relief, while the [239]*239latter are at the mercy of the defendants to receive relief because the Settlement Agreement explicitly states that the defendants’ obligation to provide any injunctive relief terminates on July 20, 2021. Like the servicemen with latent injury in Stephenson, the post-July 20, 2021 merchants are future claimants who had their claims settled for nothing. There is no evidence to suggest that merchants operating after July 20, 2021 would have, weaker'claims than those operating before July 20, 2021; yet, the Settlement Agreement consigns the former to an unambiguously inferior position. As in Literary Works, we conclude that such arbitrary harsher treatment of class members is indicative of inadequate representation.
Merchants that cannot surcharge, and those that open their doors after July 20, 2021, are also bound to an exceptionally broad release. The Settlement Agreement releases virtually any claim that (b)(2) class members would have had against the defendants for any of the defendants’ thousands of network rules. And unlike the relief, which expires on July 20, 2021, the release operates indefinitely. Therefore, after July 20, 2021, the (b)(2) class remains bound to the release but is guaranteed nothing. This release permanently immunizes the defendants from any claims that any plaintiff may have now, or will have in the future, that arise out of, e.g., the hon- or-all-cards and default interchange rules. Even if the defendants revert back to all their pre-Settlement Agreement practices, the release continues to preclude any claim based on any rule that was not altered by the Settlement Agreement! The defendants never have to worry about future antitrust litigation based on their honor-all-cards rules and their default interchange rules.
That is because the only claims that merchants post-July 20, 2021 may have are ones relating to those network rules that are explicitly changed by the injunc-tive relief in the Settlement Agreement. Those claims will become actionable only if the defendants elect to revert to their pre-Settlement Agreement rules. Of course, it remains to be seen how much the mandated rules will cost the defendants or benefit the merchants, but either way, the defendants win. If the defendants see that permitting surcharging had little effect on their business, they can decide to maintain the rules changes provided for in the in-junctive relief so that only merchants that do not accept American Express and do not operate in states like New York, California, and Texas will be able to avail themselves of that limited relief. On the other hand, if the defendants observe that surcharging took a significant toll on their business, they can revert to prohibiting surcharging and expose themselves to lawsuits that are limited to challenging the surcharging ban. In all events, merchants that cannot surcharge receive valueless relief while releasing a host of claims of unknown value.
This bargain is particularly unreasonable for merchants that begin accepting Visa or MasterCard after July 20, 2021. They will be deemed to have released all of their claims pertaining to a whole book of rules, including (perhaps most importantly) the honor-all-cards and default interchange rules, and in return have the chance that the defendants will permit surcharging. In substance and effect, merchants operating after July 20, 2021 give up claims of potential value and receive nothing that they would not otherwise have gotten. Since there was no independent representation vigorously asserting these merchants’ interests, we have no way to ascertain the value of the claims forgone. See Literary Works, 654 F.3d at 253.
[240]*240In sum, this release has much in common with the releases in Stephenson, Am-ehem, and Ortiz. Like those, this release applies to future claims and claimants, and disadvantaged class members are bound to it. The Settlement Agreement waives any claim any (b)(2) merchant would have against any defendant arising out of any of the current network rules, or those imposed in the future that are substantially similar thereto. The (b)(2) class had no notice and no opportunity to opt out of this deal. (At least the authors in Literary Works could opt out from their inadequate representation.) This Settlement Agreement is also distinguishable from releases that have passed muster. For example, the settlement release in Wal-Mart Stores (another merchant class action against Visa and MasterCard) did not bind future claimants and did not preclude new suits for similar conduct in the future. Wal-Mart Stores, 396 F.3d at 110, 113. And our approval of the Charron settlement release explicitly distinguished it from those in Amchem, Ortiz, and Literary Works on the ground that it did not extinguish claims other than those that were the subject of relief in the settlement. Charron, 731 F.3d at 252.
Merchants that cannot surcharge (by reason of state law or rules of American Express) and those that begin operating after July 20, 2021 suffer an unreasonable tradeoff between relief and release that demonstrates their representation did not comply with due process. We of course acknowledge that “[bjroad class action settlements are common, since defendants and their cohorts would otherwise face nearly limitless liability from related lawsuits in jurisdictions throughout the country.” Wal-Mart Stores, 396 F.3d at 106. And it is true that “[pjarties often reach broad settlement agreements encompassing claims not presented in the complaint in order to achieve comprehensive settlement of class actions, particularly when a defendant’s ability to limit his future liability is an important factor in his willingness to settle.” Literary Works, 654 F.3d at 247-48. But the benefits of litigation peace do not outweigh class members’ due process right.to adequate representation.
CONCLUSION
For the foregoing reasons, we vacate the district court’s certification of the class, reverse approval of the settlement, and remand for further proceedings not inconsistent with this opinion.
