No. 23–3

COINBASE, INC., PETITIONER v. DAVID SUSKI, et al.

on writ of certiorari to the united states court of appeals for the ninth circuit

 Justice Jackson delivered the opinion of the Court.

 The parties in this case executed two contracts. The first contained an arbitration provision with a delegation clause; per that provision, an arbitrator must decide all disputes under the contract, including whether a given disagreement is arbitrable. The second contract contained a forum selection clause, providing that all disputes related to that contract must be decided in California courts. Coinbase insists that the first contract’s delegation clause established the terms by which all subsequent disputes were to be resolved, so the arbitrability of a contract-related dispute between these parties is a matter for the arbitrator to decide. But respondents maintain—and the Ninth Circuit held—that the second contract’s forum selection clause superseded that prior agreement. This case thus presents the following question: When two such contracts exist, who decides the arbitrability of a contract-related dispute between the parties—an arbitrator or the court?

 Basic legal principles establish the answer. Arbitration is a matter of contract and consent, and we have long held that disputes are subject to arbitration if, and only if, the parties actually agreed to arbitrate those disputes. Here,  then, before either the delegation provision or the forum selection clause can be enforced, a court needs to decide what the parties have agreed to—i.e., which contract controls. Accordingly, we affirm the judgment of the Ninth Circuit.

I

 Coinbase, Inc., operates a cryptocurrency exchange platform. Respondents are users of Coinbase. To buy and sell cryptocurrency on the platform, users create accounts.

 The first relevant contract is the Coinbase User Agreement that respondents agreed to when they created their accounts. The User Agreement contains a provision that the contract calls the Arbitration Agreement. 1 App. 218. The Arbitration Agreement includes a delegation clause:

“This Arbitration Agreement includes, without limitation, disputes arising out of or related to the interpretation or application of the Arbitration Agreement, including the enforceability, revocability, scope, or validity of the Arbitration Agreement or any portion of the Arbitration Agreement. All such matters shall be decided by an arbitrator and not by a court or judge.” Ibid. (emphasis added).

 Respondents each agreed to the User Agreement, complete with the above-quoted arbitration language. If that were the only contract at issue, we would not be deciding this case, since the Arbitration Agreement quite clearly sends to arbitration disputes between Coinbase and its users, including disputes about arbitrability.

 These parties, though, agreed to a second contract. Coinbase offered a sweepstakes that users could enter for a chance to win a cryptocurrency called Dogecoin. Respondents each submitted entries in June 2021, and in doing so, agreed to the Official Rules of the sweepstakes. Unlike the User Agreement, the Official Rules contained a forum selection clause, which provided:

 “The California courts (state and federal) shall have sole jurisdiction of any controversies regarding the [sweepstakes] promotion and the laws of the state of California shall govern the promotion. Each entrant waives any and all objections to jurisdiction and venue in those courts for any reason and hereby submits to the jurisdiction of those courts.” Id., at 108 (capitalization altered).

 Thus, after respondents entered the sweepstakes, the parties had executed two contracts: the User Agreement, which sent disputes about arbitrability to arbitration, and the Official Rules, which appeared to send disputes to California courts.

 Once the sweepstakes concluded, the conflict between these contracts came to a head. Respondents filed a class-action complaint in the U. S. District Court for the Northern District of California, alleging that the sweepstakes violated California’s False Advertising Law, Unfair Competition Law, and Consumer Legal Remedies Act. Invoking the User Agreement and its delegation clause, Coinbase moved to compel arbitration.

 The District Court denied Coinbase’s motion. It reasoned that deciding which contract governed was a question for the court; that the User Agreement’s arbitration provision conflicted with the forum selection clause in the Official Rules; and that, under California contract law, the Official Rules superseded the User Agreement. The District Court therefore determined that the Official Rules’ forum selection clause controlled, so the parties’ sweepstakes-related dispute was not subject to arbitration. The Ninth Circuit affirmed. 55 F. 4th 1227 (2022).

 We granted certiorari to answer the question of who—a judge or an arbitrator—should decide whether a subsequent contract supersedes an earlier arbitration agreement that contains a delegation clause. 601 U. S. ___ (2023).

 II

 The Federal Arbitration Act (FAA) “reflects the fundamental principle that arbitration is a matter of contract.” Rent-A-Center, West, Inc. v. Jackson, 561 U. S. 63, 67 (2010). As a result, arbitration agreements are “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. If a court is “satisfied that the making of the agreement for arbitration . . . is not in issue,” it must send the dispute to an arbitrator. §4. “The FAA thereby places arbitration agreements on an equal footing with other contracts.” Rent-A-Center, 561 U. S., at 67.

 Given that arbitration agreements are simply contracts, “ ‘[t]he first principle that underscores all of our arbitration decisions’ is that ‘[a]rbitration is strictly a matter of consent.’ ” Lamps Plus, Inc. v. Varela, 587 U. S. 176, 184 (2019) (quoting Granite Rock Co. v. Teamsters, 561 U. S. 287, 299 (2010); some alterations in original). Arbitration is “a way to resolve those disputes—but only those disputes—that the parties have agreed to submit to arbitration.” First Options of Chicago, Inc. v. Kaplan, 514 U. S. 938, 943 (1995). Consequently, the first question in any arbitration dispute must be: What have these parties agreed to?

 As relevant here, parties can form multiple levels of agreements concerning arbitration. At a basic level, parties can agree to send the merits of a dispute to an arbitrator. They can also “agree by contract that an arbitrator, rather than a court, will resolve threshold arbitrability questions as well as underlying merits disputes.” Henry Schein, Inc. v. Archer & White Sales, Inc., 586 U. S. 63, 65 (2019). An agreement to allow an arbitrator to decide whether a dispute is subject to arbitration—i.e., its arbitrability—“is simply an additional, antecedent agreement . . . , and the FAA operates on this additional arbitration agreement just as it does on any other.” Rent-A-Center, 561 U. S., at 70.

 From these different kinds of agreements, it follows that  parties can also have different kinds of disputes. A contest over “the merits of the dispute” is a first-order disagreement, First Options, 514 U. S., at 942 (emphasis deleted), the resolution of which depends on the applicable law and relevant facts. The parties may also have a second-order dispute—“whether they agreed to arbitrate the merits”—as well as a third-order dispute—“who should have the primary power to decide the second matter.” Ibid. (emphasis deleted). Under contract principles, these second- and third-order questions are also matters of consent. “Just as the arbitrability of the merits of a dispute depends upon whether the parties agreed to arbitrate that dispute, so the question ‘who has the primary power to decide arbitrability’ turns upon what the parties agreed about that matter.” Id., at 943 (citations omitted).

  We ask who has the power to decide arbitrability because “a party who has not agreed to arbitrate will normally have a right to the court’s decision about the merits of its dispute.” Id., at 942. Thus, we have explained that “[c]ourts should not assume that the parties agreed to arbitrate arbitrability unless there is ‘clea[r] and unmistakabl[e]’ evidence that they did so.” Id., at 944 (quoting AT&T Technologies, Inc. v. Communications Workers, 475 U. S. 643, 649 (1986); some alterations in original). “[B]efore referring a dispute to an arbitrator,” therefore, “the court determines whether a valid arbitration agreement exists.” Henry Schein, 586 U. S., at 69.

III

 In prior cases, we have addressed three layers of arbitration disputes: (1) merits, (2) arbitrability, and (3) who decides arbitrability. This case involves a fourth: What happens if parties have multiple agreements that conflict as to the third-order question of who decides arbitrability? As always, traditional contract principles apply.

 Coinbase says the User Agreement’s delegation clause  controls. Respondents counter that the Official Rules’ forum selection clause superseded that agreement. If Coinbase is right that the User Agreement’s delegation clause was meant to govern all agreements moving forward, then the parties agreed to arbitrate all subsequent arbitrability disputes. If respondents are correct that the Official Rules’ forum selection clause superseded the User Agreement’s delegation clause, then the parties meant to send sweepstakes disputes—including those over arbitrability—to California courts.

 Thus, the question whether these parties agreed to arbitrate arbitrability can be answered only by determining which contract applies. In other words, “the substance of the parties’ supersession dispute is ‘whether there is an agreement to arbitrate.’ ” Field Intelligence Inc. v. Xylem Dewatering Solutions Inc., 49 F. 4th 351, 356 (CA3 2022). When we home in on the conflict between the delegation clause in the first contract and forum selection clause in the second, the question is whether the parties agreed to send the given dispute to arbitration—and, per usual, that question must be answered by a court.

 Coinbase seems to concede this point. See Reply Brief 12 (“Coinbase agrees that the Court can and should assess whether the official rules displaced the parties’ consent to have an arbitrator decide arbitrability”). Nevertheless, it offers a slew of reasons why we should revisit the Ninth Circuit’s bottom-line conclusion. None of these reasons persuades us to do so.

 First, Coinbase invokes the so-called severability principle. Under the severability principle, “an arbitration [or delegation] provision is severable from the remainder of the contract,” and “unless the challenge is to the arbitration [or delegation] clause itself, the issue of the contract’s validity is considered by the arbitrator in the first instance.” Buckeye Check Cashing, Inc. v. Cardegna, 546 U. S. 440, 445– 446 (2006). Coinbase argues that, pursuant to this principle, the Ninth Circuit should have isolated the User Agreement’s delegation provision and considered only arguments specific to that provision.

 Assuming without deciding that the severability principle is implicated here, it is nonetheless satisfied. The severability principle establishes that a party seeking to avoid arbitration must directly challenge the arbitration or delegation clause, not just the contract as a whole. But this rule does not require that a party challenge only the arbitration or delegation provision. Rather, where a challenge applies “equally” to the whole contract and to an arbitration or delegation provision, a court must address that challenge. Rent-A-Center, 561 U. S., at 71. Again, basic principles of contract and consent require that result. Arbitration and delegation agreements are simply contracts, and, normally, if a party says that a contract is invalid, the court must address that argument before deciding the merits of the contract dispute. So too here. “If a party challenges the validity . . . of the precise agreement to arbitrate at issue, the federal court must consider the challenge before ordering compliance with that [arbitration] agreement.” Ibid. (emphasis added).¹*

 Next, Coinbase contends that, as a matter of California  law, the Ninth Circuit was wrong to hold that the Official Rules’ forum selection clause superseded the User Agreement’s delegation provision. That issue is outside the scope of the question presented, and we do not address it. We took this case to decide whether, under the FAA, a court or an arbitrator decides which of the two contractual provisions controls. We decline to consider auxiliary questions about whether the Ninth Circuit properly applied state law.

 Finally, Coinbase contends that our approach will invite chaos by facilitating challenges to delegation clauses. We do not believe that such chaos will follow. In cases where parties have agreed to only one contract, and that contract contains an arbitration clause with a delegation provision, then, absent a successful challenge to the delegation provision, courts must send all arbitrability disputes to arbitration. But, where, as here, parties have agreed to two contracts—one sending arbitrability disputes to arbitration, and the other either explicitly or implicitly sending arbitrability disputes to the courts—a court must decide which contract governs. To hold otherwise would be to impermissibly “ ‘elevate [a delegation provision] over other forms of contract.’ ” Ibid. (quoting Prima Paint Corp. v. Flood & Conklin Mfg. Co., 388 U. S. 395, 404, n. 12 (1967)).

*  *  *

 We conclude that a court, not an arbitrator, must decide whether the parties’ first agreement was superseded by their second. The Ninth Circuit’s judgment is affirmed.

It is so ordered.
