New York’s Suit Against Coinbase Over Prediction Markets

New York Attorney General Letitia James’s April 21, 2026 petition against Coinbase Financial Markets, Inc. represents a significant and deliberate escalation in the ongoing conflict between state gambling regimes and the emerging market for event-based derivatives. The State alleges that Coinbase offered New York residents the ability to trade contracts on sports, entertainment, and political outcomes through an unlicensed platform, including contracts involving New York college teams and access by users under the age of 21. The petition seeks injunctive relief, disgorgement, restitution, and civil penalties.
See Petition, People v. Coinbase Fin. Mkts., Inc. (N.Y. Sup. Ct. Apr. 21, 2026).

The immediate reaction from the media has been to ask why New York chose to sue Coinbase rather than Kalshi, the federally regulated exchange at the center of the prediction-market ecosystem. That framing, while intuitive, is incomplete.

New York is actually already engaged in a direct and active dispute with Kalshi. In October 2025, the New York State Gaming Commission issued a cease-and-desist letter to Kalshi concerning sports-related event contracts. Kalshi responded by filing suit in federal court, asserting that its contracts fall within the exclusive jurisdiction of the Commodity Futures Trading Commission (“CFTC”) and are therefore insulated from state gambling law. See Complaint, KalshiEX LLC v. N.Y. State Gaming Comm’n (S.D.N.Y. 2025). If you read our articles, you already know this.

That litigation squarely presents the core preemption question. The Coinbase action should therefore be understood as an expansion of the same dispute, not a deviation from it.

From Definition to Structure

The early debate over prediction markets focused on classification. Were these products gambling, or were they derivatives? That question remains relevant, but it is no longer sufficient.

The more consequential inquiry now concerns market structure. Regulators are increasingly focused on how these products are built and delivered, and on the distinct roles played by different actors within the ecosystem:

• The exchange (e.g., a designated contract market)

• The intermediary (e.g., broker, FCM, or platform provider)

• The retail interface (the product as experienced by users)

The Coinbase petition reflects this shift. New York has not abandoned its challenge to exchange-level activity. That challenge is already underway in the Kalshi litigation. Instead, the State has moved downstream, targeting the intermediary layer through which users access the market.

This is a materially different posture. It allows the State to frame the conduct in familiar state-law terms, grounded in licensing, consumer protection, and public policy, without immediately resolving the more complex federal preemption question.

New York State of Mind

The petition alleges that Coinbase launched its prediction-market offering nationwide in early 2026 and made those markets available to New York residents. It further alleges that the platform offered contracts tied to professional and collegiate sporting events, entertainment programming, and elections.

New York’s core argument is straightforward: regardless of how these products are labeled, they function as wagers.

The legal framework reflects that approach. The State invokes:

• The New York Constitution’s prohibition on unauthorized gambling, N.Y. Const. art. I, § 9

• Penal Law definitions of gambling, N.Y. Penal Law § 225.00(2)

• The Racing, Pari-Mutuel Wagering and Breeding Law governing sports wagering, N.Y. Racing Law § 1367

• The federal Wire Act, 18 U.S.C. § 1084

• Executive Law § 63(12) as the procedural vehicle

Taken together, these provisions allow the State to argue that Coinbase is operating an unlawful gambling business within New York, irrespective of any federal characterization of the underlying contracts.

The petition also emphasizes facts that reinforce this framing. It alleges that Coinbase:

• Permitted participation by individuals aged 18 to 20

• Offered contracts involving New York college teams

• Provided mobile access and facilitated participation within the State

These allegations serve to anchor the case in traditional state police powers, particularly those related to youth protection and regulation of in-state collegiate athletics.

Coinbase’s Position and the Federal Framework

Coinbase’s position reflects the prevailing industry approach. It has described its prediction markets as platforms for trading contracts on future events, with prices reflecting market-implied probabilities. This aligns with how the CFTC has characterized event contracts, which are typically structured as binary instruments with fixed payouts.

The Commodity Exchange Act (“CEA”) provides the statutory foundation for that position. The Act grants the CFTC exclusive jurisdiction over certain derivatives transactions, including swaps traded on registered entities.
See 7 U.S.C. § 2(a)(1)(A).

Event contracts traded on designated contract markets fall within this framework, subject to the CFTC’s oversight. The statute also includes a specific provision addressing event contracts, authorizing the CFTC to prohibit contracts that are contrary to the public interest, including those involving gaming or unlawful activity.
See 7 U.S.C. § 7a-2(c)(5)(C); 17 C.F.R. § 40.11.

This structure creates a critical tension. On one hand, the federal regime contemplates a centralized determination, by the CFTC, of which contracts may be listed. On the other hand, the statutory reference to “gaming” and unlawful activity preserves a role for public-policy considerations that have traditionally been addressed at the state level.

Coinbase’s argument, consistent with the federal position, is that Congress assigned that gatekeeping function to the CFTC, not to individual states. New York’s position is that the existence of federal regulation does not displace state authority over gambling, particularly where the activity at issue resembles wagering in substance.

The Kalshi Litigation

The Kalshi litigation represents the most direct and consequential articulation of this conflict.

Kalshi operates as a CFTC-regulated designated contract market. Its federal action against New York presents a clean legal question: whether state gambling laws can be applied to event contracts traded on such a platform.

Recent case law illustrates the uncertainty in this area.

In KalshiEX LLC v. Flaherty, the Third Circuit held that sports-related event contracts traded on a designated contract market qualified as swaps and that federal law preempted state regulation of those contracts. The court emphasized the CFTC’s exclusive jurisdiction and the need for a uniform federal framework.

By contrast, in KalshiEX LLC v. Moore, a federal district court in Maryland declined to grant preliminary injunctive relief, finding that Kalshi had not demonstrated a likelihood of success on its preemption claim. The court emphasized the presumption against preemption in areas of traditional state authority, including gambling regulation.

These decisions underscore that the law remains unsettled, particularly with respect to the intersection of federal derivatives regulation and state police powers.

Why Target Coinbase

Against that backdrop, New York’s decision to proceed against Coinbase reflects a set of strategic considerations.

1. Avoiding Duplication of the Kalshi Dispute

The central preemption issue is already being litigated in the Kalshi case. Bringing a parallel action against Kalshi would add little doctrinal value while increasing procedural complexity.

2. Leveraging a More Conventional Fact Pattern

The Coinbase petition is grounded in facts that are familiar to state courts: retail onboarding, age restrictions, mobile access, and specific wagers. These facts allow the State to frame the case as a straightforward enforcement action under existing gambling laws.

3. Preserving Arguments Against Intermediaries

Even if federal law ultimately preempts state regulation of exchange-traded event contracts, it does not necessarily follow that intermediaries are fully insulated. The Coinbase case tests whether state law may still apply to the retail-facing layer of the market.

This distinction may prove critical. It raises the possibility that different components of the same ecosystem could be subject to different regulatory regimes.

The Event-Contract Constraint

An additional layer of complexity arises from the CEA’s treatment of event contracts.

The statute and implementing regulations recognize that certain contracts, including those involving gaming or unlawful activity, may be contrary to the public interest. This creates a potential point of convergence between federal and state concerns.

New York is likely to argue that the contracts at issue fall within that category and should not be permitted under the federal framework in the first instance. The federal response is that the CFTC, not the states, is responsible for making that determination.

This issue goes to the heart of the dispute. It is not simply a question of whether federal law preempts state law. It is a question of who decides whether a given contract is permissible.

Implications for Market Participants

The Coinbase action highlights several important considerations.

First, regulatory risk extends beyond exchanges. Intermediaries and retail-facing platforms are likely to face increased scrutiny, particularly where their products resemble traditional wagering.

Second, federal regulatory status does not eliminate all state-law exposure. The interaction between federal and state regimes remains unresolved, and different layers of the market may be treated differently.

Third, litigation strategy will matter. The outcome of the Kalshi case will shape the legal landscape, but it will not necessarily resolve all questions concerning intermediaries.

Conclusion

New York’s suit against Coinbase is not a departure from its position on prediction markets. It is a continuation of that position, pursued through a different target.

The State is already engaged with Kalshi on the central preemption issue. The Coinbase action extends that challenge to the distribution layer, where the product is delivered to users and where state-law considerations are more readily framed.

The broader dispute will not be resolved in a single case. It is unfolding across multiple fronts, with different actors and different legal theories. The key question is no longer simply whether prediction markets are gambling or derivatives. It is whether a federally regulated market structure can coexist with state authority over activities that, in substance, resemble wagering.

That question remains open, but the defenses are strong.
