delivered the opinion of the Court.
In this case, we are asked to decide whether respondents can be compelled to arbitrate claims arising under the Racketeer Influenced and Corrupt Organizations Act (RICO), 18 U. S. C. § 1961 et seq., notwithstanding the fact that the parties’ arbitration agreements may be construed to limit the arbitrator’s authority to award damages under that statute.

Respondents are members of a group of physicians who filed suit against managed-health-care organizations including petitioners PacifiCare Health Systems, Inc., and Pacifi-Care Operations, Inc. (collectively, PacifiCare), and United-Healthcare, Inc., and UnitedHealth Group Inc. (collectively, United). These physicians alleged that the defendants unlawfully failed to reimburse them for health-care services that they had provided to patients covered by defendants’ health plans. They brought causes of action under RICO, the Employee Retirement Income Security Act of 1974 (ERISA), and federal and state prompt-pay statutes, as well as claims for breach of contract, unjust enrichment, and

quantum meruit. In re: Managed Care Litigation,
Of particular concern here, PacifiCare and United moved the District Court to compel arbitration, arguing that provisions in their contracts with respondents required arbitration of these disputes, including those arising under RICO.
Ibid.
Respondents opposed the motion on the ground that, because the arbitration provisions prohibit an award of punitive damages, see App. 107, 147, 168, 212, respondents could not obtain “meaningful relief” in arbitration for their claims under the RICO statute, which authorizes treble damages, 18 U. S. C. § 1964(c). See
Paladino
v.
Avnet Computer Technologies, Inc.,
The District Court denied petitioners’ request to compel arbitration of the RICO claims.
II
Petitioners argue that whether the remedial limitations render their arbitration agreements unenforceable is not a question of “arbitrability,” and hence should have been decided by an arbitrator, rather than a court, in the first in *404 stance. They also claim that even if this question is one of arbitrability, and is therefore properly within the purview of the courts at this time, the remedial limitations at issue do not require invalidation of their arbitration agreements. Either way, petitioners contend, the lower courts should have compelled arbitration. We conclude that it would be premature for us to address these questions at this time.
Our decision in
Vimar Seguros y Reaseguros, S. A.
v.
M/V Sky Reefer,
Notwithstanding Vimar’s insistence that the arbitration agreement violated federal policy as embodied in COGSA, we declined to reach the issue and held that the arbitration clause was, at least initially, enforceable. “At this interlocutory stage,” we explained, “it is not established what law the arbitrators will apply to petitioner’s claims or that petitioner *405 will receive diminished protection as a result. The arbitrators may conclude that COGSA applies of its own force or that Japanese law does not apply so that, under another clause of the bill of lading, COGSA controls.” Id., at 540. We farther emphasized that “mere speculation that the foreign arbitrators might apply Japanese law which, depending on the proper construction of COGSA, might reduce respondents’ legal obligations, does not in and of itself lessen liability under COGSA §3(8),” nor did it provide an adequate basis upon which to declare the relevant arbitration agreement unenforceable. Id., at 541 (emphases added). We found that “[wjhatever the merits of petitioner’s comparative reading of COGSA and its Japanese counterpart, its claim is premature.” Id., at 540.
The case at bar arrives in a similar posture. Two of the four arbitration agreements at issue provide that “punitive damages shall not be awarded [in arbitration],” App. 107, 147; one provides that “[t]he arbitrators . . . shall have no authority to award any punitive or exemplary damages,”
id.,
at 212; and one provides that “[t]he arbitrators . . . shall have no authority to award extra contractual damages of any kind, including punitive or exemplary damages
... ,” id.,
at 168. Respondents insist, and the District Court agreed,
Our cases have placed different statutory treble-damages provisions on different points along the spectrum between purely compensatory and strictly punitive awards. Thus, in
Vermont Agency of Natural Resources
v.
United States ex rel. Stevens,
In light of our case law’s treatment of statutory treble damages, and given the uncertainty surrounding the parties’ intent with respect to the contractual term “punitive,”
1
the application of the disputed language to respondents’ RICO claims is, to say the least, in doubt. And
Vimar
instructs that we should not, on the basis of “mere speculation” that an arbitrator might interpret these ambiguous agreements
*407
in a manner that casts their enforceability into doubt, take upon ourselves the authority to decide the antecedent question of how the ambiguity is to be resolved.

It is so ordered.
Notes
Contrary to respondents’ contention, the prohibition in Dr. Manual Porth’s contract against an arbitrator’s awarding “extracontractual” damages is likewise ambiguous. This language might mean, as respondents would %ave it, that an arbitrator is prohibited from awarding any damages other than for breach of contract. Brief for Respondents 20-21. But it might only mean that an arbitrator cannot award noneconomic damages such as punitive or mental-anguish damages. See 3 D. Dobbs, Law of Remedies: Damages-Equity-Restitution § 12.1(1), p. 8 (2d ed. 1993) (“Punitive damages and mental anguish damages are thus considered ‘extra-contractual,’ and usually denied in pure contract cases”).
If the contractual ambiguity could itself be characterized as raising a “gateway” question of arbitrability, then it would be appropriate for a court to answer it in the first instance. But we noted just this Term that “the phrase ‘question of arbitrability’ has a ... limited scope.”
Howsam
v.
Dean Witter Reynolds, Inc., 537
U. S. 79, 83 (2002). Indeed, we have “found the phrase [question of arbitrability] applicable in the kind of narrow circumstance where contracting parties would likely have expected a court to have decided the gateway matter, where they are not likely to have thought that they had agreed that an arbitrator would do so, and, consequently, where reference of the gateway dispute to the court avoids the risk of forcing parties to arbitrate a matter that they may well not have agreed to arbitrate.”
Id.,
at 83-84. Givedn our presumption in favor of arbitration,
