New York sues Kalshi for operating an unlicensed gambling platform

The New York State Office of the Attorney General filed suit on 31 July 2026 alleging that KalshiEX, LLC is operating an unlicensed gambling business in New York through its prediction-market platform. The filing brings the case under New York Penal Law § 225.00 et seq., framing the dispute as a state gambling enforcement action rather than a market-structure debate.

The complaint says Kalshi "launched in 2021 as a service that allowed users to bet money on the outcome of a wide range of future events". It alleges that, in 2025, the company launched sports "trading" while "claiming it offered legal sports betting markets, accessible to Americans in all 50 states, and encouraging bettors to wager on the outcomes of major sporting events". New York is treating the product as gambling under state law, not accepting the platform's own product label.

The pleading is direct on licensing. The attorney general's office said Kalshi "has failed to obtain a license from the New York State Gaming Commission (Gaming Commission), sidestepping its obligation to pay taxes like licensed casinos and mobile sports gambling platforms do". It also alleges an age-access issue, stating Kalshi's prediction markets are available to users aged 18 to 20 even though New York law requires a person to be at least 21 to participate in mobile sports betting.

According to the press release and complaint materials, the state is seeking a court order stopping Kalshi from operating as an unlicensed gambling business in New York, plus fines, forfeiture of "all illegal gains", and restitution to users. The office is asking the court to require Kalshi "to forfeit all illegal gains, distribute restitution to consumers who were harmed, and pay fines equal to three times the gains the company made through its illegal actions". For compliance teams at prediction-market platforms, the operational read is straightforward: state gambling licensing, tax treatment and age-gating are being pleaded together, which makes this a replicable state template for unlicensed gambling allegations.

Attorney General Letitia James said in the release that New York had sued Kalshi for "running an illegal gambling operation". The filing does not specify a hearing date or Kalshi's response deadline. The next step is docket movement in the New York court, including service, Kalshi's first response and any early application on injunctive relief.
