What happened
New York Attorney General Letitia James and Governor Kathy Hochul announced a lawsuit on September 24, 2026 against QCX LLC, which does business as Polymarket US. The state said Polymarket ran an illegal, unlicensed gambling operation in New York through its prediction market, without a license from the New York State Gaming Commission. Reuters reported that the suit was filed in a state court in Manhattan. The state also objected to the platform allowing users aged 18 to 20, when New York sets 21 as the minimum age for mobile sports betting.
The attorney general's office said the suit sought an order stopping the unlicensed operation in New York, forfeiture of illegal gains, restitution to consumers, and fines equal to three times the gains. Reuters reported that Polymarket sued the state in Manhattan federal court several hours later. Polymarket said the Commodity Futures Trading Commission has exclusive authority to regulate prediction markets, and asked for a declaration that New York cannot enforce its civil and criminal gambling laws against it. Reuters said New York described the value of Polymarket's business as reportedly exceeding $20 billion. Neither source reported a ruling.

Why it matters
The suit challenges whether Polymarket US can operate in New York without a state gaming license. The relief sought includes a stop order, forfeiture and fines of three times the gains, which bears on how a buyer would weigh the business in that state.
Polymarket argues the CFTC has exclusive authority, while the state treats the markets as gambling. The sources report no ruling, so the regulatory basis for operating in New York is unresolved.
