New York Attorney General Letitia James and Governor Kathy Hochul sued Polymarket’s U.S. business on Thursday, alleging it operates an unlicensed gambling business in the state. The lawsuit targets QCX LLC, which does business as Polymarket US, and asks a court to block the platform from operating without a gambling license.
The state is also seeking restitution for customers, forfeiture of alleged illegal gains and financial penalties equal to three times those gains. New York argues that Polymarket’s contracts on sporting events amount to gambling because users put money on uncertain outcomes. The state also alleges that the platform allows users ages 18 to 20 to participate, below New York’s 21-year minimum for mobile sports betting.
Why it matters
The case adds to a widening jurisdictional fight over prediction markets. Companies including Polymarket and Kalshi argue that event contracts are financial products subject to federal oversight by the Commodity Futures Trading Commission. States have countered that sports-related contracts function as bets and must comply with state gambling laws.
Polymarket returned to the U.S. market in December 2025 with sports markets and said it planned to expand into other categories. New York has separately sued Kalshi, seeking as much as $36 billion in penalties and disgorgement. Several disputes have moved through appeals courts, including a Kalshi case involving New Jersey that has reached the U.S. Supreme Court.
Market impact
The immediate risk is operational and legal rather than a token-price event. A court order could restrict Polymarket’s U.S. sports offering in New York and increase compliance costs for prediction-market operators. The broader outcome will help determine whether sports event contracts are treated as federally regulated products or state-regulated gambling.
