The lawsuit follows a comprehensive investigation conducted by the Office of the Attorney General, which concluded that the speculative markets hosted on Polymarket satisfy New York’s strict legal definition of gambling. According to state investigators, users on the platform stake digital assets on uncertain future outcomes that they cannot control or influence, characteristics that align squarely with traditional forms of wagering rather than recognized financial investments.
Furthermore, the complaint alleges that Polymarket has consistently operated without obtaining the mandatory licenses from the New York State Gaming Commission. By failing to secure proper state authorization, the platform has allegedly bypassed the regulatory oversight and tax obligations that traditional, brick-and-mortar casinos and licensed mobile sports betting operators are legally required to fulfill. In New York, tax revenues generated from legal gaming activities are earmarked to support vital public programs, including public schools, local youth sports initiatives, and specialized treatment programs for problem gambling.
The legal showdown arrives at a critical juncture for the digital asset and derivatives industries. Federal financial regulators, including the Securities and Exchange Commission and the Commodity Futures Trading Commission, have increasingly turned their attention toward crypto-powered prediction markets, seeking to establish clear regulatory frameworks for decentralized and blockchain-based financial tools.
At the heart of the broader industry debate is a fundamental disagreement over how these platforms should be classified. Polymarket and its primary competitor, Kalshi, have consistently maintained that they are not gambling websites at all. Instead, they position themselves as federally regulated exchanges that offer "event contracts"—a specialized form of financial derivative. Under this legal theory, the companies argue they should fall exclusively under the jurisdiction of the Commodity Futures Trading Commission rather than being subjected to patchwork state gaming laws.
The Commodity Futures Trading Commission has largely aligned itself with the platforms’ perspective in this ongoing turf war. Demonstrating the gravity of the federal dispute, the CFTC took the unprecedented step of suing nine individual states earlier this year, asserting that federal law grants the agency exclusive nationwide authority over the event contract industry, thereby preempting state-level enforcement efforts.
Despite the federal friction, New York officials are pressing forward with local enforcement, emphasizing the specific risks posed to younger demographics. Thursday’s court filing explicitly highlights that Polymarket’s platform has remained accessible to individuals aged 18 to 20. This practice directly conflicts with New York state law, which mandates that participants in mobile sports betting and commercial gaming must be at least 21 years old.
In announcing the lawsuit, Attorney General James sharply criticized the platform’s accessibility and operational model. By skirting New York’s laws, James asserted, Polymarket is directly targeting the most vulnerable populations. Governor Hochul echoed these sentiments, stating that the company had knowingly violated established state laws and recklessly put underage users at financial and personal risk.
Through the lawsuit, the state of New York is petitioning the court to issue a permanent injunction barring Polymarket from operating any unlicensed gambling operations within the state. Additionally, the state is demanding that the company forfeit all illegal gains amassed from New York users, pay full restitution to harmed consumers, and face severe financial penalties amounting to triple the value of the platform’s ill-gotten gains.
This legal action represents only the latest maneuver in an aggressive, sustained campaign by New York authorities against crypto and gambling-adjacent platforms operating within state lines. Earlier this summer, in July, James and Hochul filed a similar lawsuit against rival prediction market Kalshi. Prior to that, in April, the Attorney General targeted major digital asset exchanges Coinbase and Gemini over separate regulatory compliance claims. Continuing the enforcement sweep earlier this month, James successfully secured an $8 million financial settlement from the leading operator of sweepstakes casinos in the state.
Polymarket officially launched its operations in the United States in December 2025. Initially, the platform rolled out features allowing domestic users to place bets on various sporting events, with broader strategic plans to expand its offerings into prediction markets covering a wide array of political, economic, and cultural topics. As the legal battle in New York unfolds, the outcome threatens to establish a critical precedent for how prediction markets and decentralized exchanges navigate state versus federal regulatory boundaries nationwide.
