• New York Attorney General Letitia James has sued Coinbase and Gemini, accusing both crypto platforms of violating state gambling laws through their prediction markets offerings, citing breaches of state tax obligations and age restriction requirements
• James argues the platforms fall within New York's legal definition of gambling and are exposing residents under 21 to addictive platforms without adequate safeguards, stating that "gambling by another name is still gambling"
• Coinbase's chief legal officer Paul Grewal has pushed back, arguing prediction markets are federally regulated national exchanges under CFTC jurisdiction and that the issue is already being contested in New York federal court
• The CFTC has taken an increasingly assertive position in defence of the sector, with chair Michael Selig having argued the agency holds exclusive jurisdiction over prediction markets and the CFTC having sued Arizona, Connecticut and Illinois earlier this month over their own attempts to restrict the platforms
• The lawsuits follow both Coinbase and Gemini announcing pushes into prediction markets late last year, adding two of the crypto industry's most prominent names to a growing list of platforms facing state-level legal challenges

New York Has Opened a New Front in America's Prediction Markets War

New York Attorney General Letitia James has filed suit against Coinbase and Gemini, bringing two of the most recognisable names in the cryptocurrency industry into the centre of America's expanding legal battle over prediction markets. The lawsuits, filed on Tuesday, accuse both platforms of running illegal gambling operations in violation of New York state law, with James arguing that the prediction markets label does not change the fundamental nature of what the platforms are offering.

The legal basis of James's action rests on New York's definition of gambling and its associated regulatory framework. Both platforms are accused of breaching state tax obligations and, critically, of failing to apply New York's age restriction of 21 for gambling products. That second allegation adds a consumer protection dimension that goes beyond the jurisdictional dispute at the heart of most state-level prediction markets cases, framing the issue not just as a tax and licensing question but as a failure to protect young users from addictive products.

James was direct in her characterisation of the platforms, describing them as illegal gambling operations that lack the guardrails required of licensed gambling products in New York. The reference to addictive characteristics and inadequate consumer protections echoes the language France's ANJ used earlier this year when it warned that prediction market platforms amplify the addictive qualities of gambling without providing the protective mechanisms that licensed operators are required to maintain.

Coinbase's chief legal officer Paul Grewal responded quickly and forcefully, restating the industry's standard counter-argument: that prediction markets are federally regulated national exchanges operating under CFTC oversight, and that Congress intended federal rather than state jurisdiction to apply. Grewal noted the matter is already being litigated in New York federal court, signalling that Coinbase intends to fight the state action on jurisdictional grounds rather than engage with it on its merits.

Gemini had not issued a public response at the time of writing.

The timing of the New York action is notable given the CFTC's increasingly aggressive posture in defence of the sector. Chair Michael Selig has publicly argued that his agency holds exclusive jurisdiction over prediction markets, and the CFTC moved earlier this month to sue Arizona, Connecticut and Illinois over their own attempts to restrict prediction market platforms within their borders. That federal intervention in state regulatory efforts represents a significant escalation, and it sets up a direct confrontation between federal authority and state consumer protection powers that will ultimately need to be resolved at the highest levels of the American legal system.

Kalshi, which has been fighting state-level challenges across the country, previously sued New York over its own regulatory efforts against the platform. The addition of Coinbase and Gemini to the roster of companies facing New York action significantly raises the profile of the dispute and increases the commercial and political pressure on both sides to seek a definitive resolution.

New York's Entry Changes the Scale of This Battle

Most of the state-level prediction markets cases to date have involved regulators in markets that, while significant, are not the centre of American financial and legal gravity. New York is different. As the home of Wall Street, the country's most sophisticated financial regulatory environment and one of its largest consumer markets, a New York Attorney General action carries weight that a Nevada gaming board order or an Arizona misdemeanour charge simply does not. James's decision to target Coinbase and Gemini specifically, rather than prediction-market-native operators like Kalshi, also changes the political and commercial calculus. These are publicly listed, institutionally held companies with billions in market capitalisation, extensive legal resources and strong incentives to fight rather than settle. The prediction markets legal battle has just acquired two of its most formidable defendants.

The Age Restriction Argument Is the States' Strongest Card

Among the various legal theories being deployed against prediction markets at state level, the age restriction argument deserves particular attention. The jurisdictional dispute over whether the CFTC or state gambling regulators have authority over event contracts is a complex and genuinely contested legal question. But the argument that platforms are exposing under-21 users to gambling-like products without adequate age verification controls is more viscerally compelling and considerably harder for the industry to dismiss on technical grounds. If states can demonstrate that prediction market platforms are being accessed by minors without the safeguards required of licensed gambling operators, they shift the debate from abstract jurisdictional theory to concrete consumer harm. That is a much stronger position from which to seek judicial intervention, and it is one that even a pro-industry CFTC will struggle to defend against publicly.

The CFTC's Legal Offensive Against States Is a High-Stakes Gamble

The CFTC's decision to sue Arizona, Connecticut and Illinois over their prediction markets restrictions, and its broader assertion of exclusive federal jurisdiction, represents a bold strategic choice that could either definitively resolve the state versus federal question in the industry's favour or trigger a constitutional confrontation that sets the sector back significantly. Federal agencies do not typically sue states over regulatory jurisdiction without high confidence in their legal position, and Selig's public statements suggest the CFTC believes it is on strong ground. But the political environment surrounding prediction markets, particularly following the congressional hearing that exposed deep unease in Washington about insider trading and market integrity, means that a CFTC victory in court would not necessarily translate into political acceptance of the current regulatory framework. The industry needs both legal vindication and political legitimacy, and the two are not guaranteed to arrive together.
