New York sues Polymarket as an illegal gambling site; licensed sportsbooks hand the state 51% of their take
The attorney general wants Polymarket US to forfeit its New York gains and pay triple fines. The state's own data shows what is at stake: licensed mobile sportsbooks sent $1.33 billion to education last fiscal year.
New York Attorney General Letitia James and Governor Kathy Hochul sued Polymarket's U.S. business on Thursday, saying its prediction market is an unlicensed gambling operation. The complaint targets QCX LLC, which does business as Polymarket US, and asks a court to stop it operating in the state without a license, according to the attorney general's office.
The state wants Polymarket to give up all gains from New York users, pay restitution, and pay fines equal to three times those gains. CNBC reported that the suit also seeks $100,000 for each attempt or offer of sports wagering in New York, along with an account of every trade placed, the money users lost and what Polymarket earned.
What the state says Polymarket did
The attorney general's case rests on three points. First, event contracts on uncertain outcomes meet New York's legal definition of gambling. Second, Polymarket never obtained a license from the New York State Gaming Commission, so it pays none of the gaming taxes that licensed sportsbooks pay. Third, the platform accepts users aged 18 to 20, while the state requires mobile sports bettors to be at least 21.
Polymarket US launched in December 2025 and is regulated by the Commodity Futures Trading Commission. Its chief legal officer, Neal Kumar, told CNBC the company has more than 350 employees in New York, called the filing a "copy/paste" of a recycled lawsuit and said, "we'll fight for our users."
This is New York's third case of the kind this year. The state sued Coinbase and Gemini over their prediction products in April and Kalshi in July. According to Cointelegraph, CFTC Chair Michael Selig has said the agency has "exclusive jurisdiction" over these platforms, and New Jersey has asked the U.S. Supreme Court to hear its own dispute with Kalshi.
The number behind the lawsuit: 51 cents of every dollar
The press release says the case is about the tax money that licensed operators pay. The Gaming Commission's monthly sports wagering report shows how much money that is.
| New York mobile sports betting | FY 2025-26 (Apr-Mar) | FY 2026-27 so far (Apr-Aug) |
|---|---|---|
| Amount wagered (handle) | $26.16 billion | $10.16 billion |
| Operator gross gaming revenue | $2.60 billion | $947.9 million |
| Sent to the state for education | $1.33 billion | $483.5 million |
That works out to about 51% of licensed sportsbooks' gross gaming revenue going to the state. Operators kept roughly 9.9 cents of every dollar wagered last fiscal year, and about half of that went to Albany. A platform with no license pays none of that. That gap is why states and the CFTC are fighting over these platforms, and it is the reason the state gave for bringing this case.
The state's data does not show prediction markets draining the licensed books so far. Handle from April through August 2026 was $10.16 billion, up 7.4% from $9.46 billion a year earlier. The months swing a lot: July wagers rose 34% from a year earlier, while August fell 15% to $1.73 billion. The report does not explain the changes, and one month is not a trend.
What traders and operators should watch
Polymarket users in New York face the most direct risk. According to Cointelegraph, the filing says the state could seek to block the platform for residents. Nothing in the release says New Yorkers must close accounts now, but a court order could change that.
Licensed sportsbooks have the opposite interest. Every state win keeps sports event contracts inside a system where the operator pays about half its gross revenue in tax. Anyone trading event contracts across platforms should know that the price of the same outcome can differ between a CFTC-regulated venue and a licensed book. Our sportsbook odds board shows the licensed side of that comparison.
The bigger question is which regulator wins. If the Supreme Court takes New Jersey's case, it could decide the issue for every state at once. Until then, each state lawsuit is another test of how far the CFTC's claim of exclusive jurisdiction reaches.
