New York Sues Coinbase, Gemini Over Prediction Market Offerings
New York Attorney General Letitia James filed suit against Coinbase and Gemini on 21 April 2026, accusing the cryptocurrency exchanges of operating unlicensed prediction markets that New York law classifies as illegal gambling. The action targets both platforms' event-based trading offerings, with the attorney general's office alleging that contracts touching on sports, entertainment, and other real-world outcomes constitute unlawful wagering under the state's gambling statutes. The suit adds New York to a growing list of state regulators moving against prediction market operators over the past twelve months.
Prediction markets allow users to buy and sell contracts tied to the outcomes of events — election results, earnings reports, sporting contests — with prices fluctuating based on collective expectations about what will occur. Platforms argue the markets serve a legitimate informational function, aggregating dispersed knowledge into price signals that can function as forecasting tools. The attorney general's office rejected that framing in its complaint, characterizing the products as gambling operations dressed in financial language. "Gemini and Coinbase's so-called prediction markets are just illegal gambling operations," James's office stated in the filing, without distinguishing between the two respondents.
What the state alleges
The core of New York's case turns on whether prediction market contracts satisfy the legal definition of a wager under the state's penal code. New York law defines gambling broadly: any scheme where consideration is paid for the opportunity to win a prize based, in whole or in part, on chance constitutes an illegal lottery. The attorney general's office has apparently concluded that prediction market contracts — where users stake money on uncertain future events — fit that definition regardless of how platforms label them. The suit names the platforms directly and seeks injunctive relief prohibiting further operation of the relevant products in New York.
The sources do not specify whether the complaint names individual contracts, named market events, or particular dollar volumes at issue. What is clear is the legal theory: New York views these instruments as wagering instruments subject to the state's gambling licensing regime, which imposes strict requirements on operators seeking to conduct gaming activity legally within the jurisdiction. The attorney general's office is seeking to shut the products down rather than negotiate a licensing pathway, at least in the initial filing.
The companies' likely response
Neither Coinbase nor Gemini has issued a full response to the complaint as of the filing date, though both companies have histories of regulatory engagement that suggest the litigation will be contested rather than settled quietly. Gemini, founded by Cameron and Tyler Winklevoss, has navigated prior Securities and Exchange Commission actions and has maintained that its offerings are structured to comply with applicable law. Coinbase, the larger and more litigation-experienced of the two, has spent years pushing for regulatory clarity from federal authorities and has publicly argued that prediction markets should be treated as financial instruments rather than gaming products. Both companies are likely to argue that the element of skill and information analysis involved in forecasting real-world events distinguishes their markets from pure chance gambling, and that applicable law does not clearly cover their structures.
That counterargument cuts both ways. If prediction markets are sophisticated forecasting tools rather than games of chance, the question becomes who should regulate them — and on what timeline. Federal oversight by the Commodity Futures Trading Commission has covered some prediction market contracts, particularly those involving commodity prices, but the CFTC has not issued comprehensive guidance on event-based markets tied to sports, entertainment, or elections. Congress has not passed legislation specifically addressing the category. That regulatory gap is precisely what New York is now exploiting, using state gambling law to fill the vacuum.
A broader enforcement pattern
New York is not acting in isolation. Multiple states have moved against prediction market operators over the past year, with a consistent legal theory: event-based trading contracts that allow users to stake consideration on uncertain outcomes constitute gambling regardless of the platforms' self-characterization. The enforcement pattern has created a de facto national policy on prediction markets — one driven by state attorneys general rather than federal legislation or agency rulemaking. The result is a fragmented regulatory landscape where the legality of operating a prediction market depends heavily on where users are located.
The structural question this litigation surfaces is whether prediction markets are more like casinos or more like financial exchanges. That classification determines which regulatory apparatus applies: gambling law, which is state-level and designed around consumer protection in games of chance, or securities and commodities law, which is federal and calibrated toward information-efficient markets. The stakes of that distinction are considerable for an industry that Pitchbook estimated had grown to approximately $8 billion in notional volume by late 2025. If prediction markets are classified as gambling, operators face state licensing requirements that few have sought and that carry substantial compliance costs. If they are financial instruments, federal frameworks offer a clearer pathway to legitimacy — one that Coinbase, in particular, has long argued should apply.
Stakes and what happens next
If New York prevails at the trial court level, the practical consequences for Coinbase and Gemini would be significant. An injunction shutting down prediction market products in New York would remove a meaningful segment of their user base from a product generating substantial activity. The companies could comply and restructure their offerings, attempt to geo-block New York users from the relevant markets, or appeal. A loss on the underlying legal question — whether prediction market contracts constitute gambling under New York law — would create precedent that other state regulators could cite in analogous enforcement actions.
The companies' strongest substantive argument may be that the markets they operate reward analysis and information aggregation rather than pure chance — that participants who correctly forecast outcomes are compensated because they identified genuine probability, not because luck broke their way. Courts have grappled with similar distinctions in other gambling-related cases, sometimes distinguishing games of pure chance from games where skill is a material factor. Whether that distinction saves Coinbase and Gemini's products under New York's specific gambling statutes remains genuinely open. The complaint does not suggest the attorney general's office found that argument persuasive in drafting the suit.
The sources do not provide a trial date, a hearing schedule, or the specific contractual terms New York is challenging. What is clear is that the attorney general has made a decision: these products violate state law, the companies should stop operating them, and litigation is the appropriate mechanism to enforce that view. The next several months will determine whether the courts agree.
This publication covered the New York attorney general's filing as an enforcement action under state gambling statutes, foregrounding the specific legal theory rather than treating the suit as a generalized regulatory threat. The dominant wire framing emphasized the crypto angle; the structural question of whether federal or state frameworks should govern prediction markets received more column inches here.
