Why New York Says This Betting Site Is Illegal Gambling
New York sued Polymarket on Sept. 24, 2026, at 10:20 a.m. EDT for alleged illegal gambling. Gov. Kathy Hochul and Attorney General Letitia James announced the case together.
The company sued is QCX LLC, which does business as Polymarket US. The case was brought in New York. The state says the company ran illegal gambling in New York through its prediction market, a website where people put money on what will happen in the future. The Governor's news page lists it under the headline "Lawsuit Against Illegal Gambling" Governor's news page.
The announcement did not say what penalty the state wants. That will be spelled out in the court papers themselves.
This case follows a separate case against Kalshi. According to a July 31, 2026 release, Hochul and James announced New York has sued Kalshi OAG announcement. In that case, the state asked the court to make Kalshi give up money made illegally and pay money back to users.
On July 8, 2026, Hochul and James said they "will continue to hold all gambling platforms, including prediction markets, accountable to the law." On April 24, 2026, James and Hochul defended enforcement actions against prediction markets OAG release. On that same date, James joined other states in defending state gambling laws.
On Aug. 7, 2026, the New York Post published an article by Charles Gasparino about Hochul and James going after Kalshi but not Polymarket Post report. The Sept. 24 announcement came after that article. Two prediction-market operators are now being challenged in the same state.
Massachusetts Attorney General Campbell also sued Kalshi over illegal and unsafe sports betting. That office says Kalshi's sports operation skips safety rules that licensed betting companies must follow.
On Jan. 20, 2026, Campbell won a court order that will block Kalshi from offering unlawful sports bets in Massachusetts Massachusetts order. The office said Kalshi has neither applied for nor received a sports betting license from the MGC, as required by law. Think of it like a driver's license: you cannot legally drive without one, even if you know how to drive.
On May 1, 2026, New Jersey Attorney General Davenport led other attorneys general in asking the CFTC, the federal agency that oversees trading markets, to respect state power over sports prediction markets Coalition letter. The letter was a reply to a CFTC request for public comments on proposed rules for prediction markets.
What this means for your money is simple. If courts call these trades gambling, the business changes from collecting small fees to possibly giving up profits, paying users back, and being ordered to stop.
The bigger fight here is over who sets the rules. States say sports bets need a state license, age checks, and safety rules, no matter what screen they are sold on. They are making that case in court and in letters to federal regulators.
In my view, the next questions are narrow. Which bets does New York say count as gambling. How will the court tell the difference between market research and betting on an outcome. And how much will the state court listen to federal market rules. The answers will turn on licenses and legal definitions, not on who predicts best.
