New York Sues Polymarket Over Alleged Unlicensed Betting Operation

New York has sued Polymarket, accusing the prediction-market app of running an unlicensed betting business and exposing users in the state, including people aged 18 to 20, to activities that New York says are illegal sports wagering. For payment providers in high-risk verticals, the case is another reminder that prediction markets are being treated less like a neat regulatory gray area and more like a jurisdiction fight with real licensing and age-verification consequences.

1. According to the New York Attorney General, Polymarket is “an illegal, unlicensed operation.” The state says the platform offers event contracts that, in the case of sports outcomes, amount to sports betting under New York law.
2. The lawsuit asks the court to block Polymarket from operating as a sports betting business and to impose penalties, including forfeiture of profits and restitution to users. In practice, that is the sort of relief that can quickly get a payments stack very uncomfortable.
3. New York argues that Polymarket’s products meet the legal definition of gambling because the outcomes are “uncertain and beyond the control of the bettor, or depend on chance.” The state also says Polymarket does not have a license from the State Gaming Commission.
4. The complaint says the platform is available to users aged 18 to 20, while New York law requires at least 21 years old to participate in mobile sports betting. That age gap matters because it turns a product issue into a compliance issue for onboarding, KYC, and transaction monitoring.
5. New York also says Polymarket is avoiding taxes that would fund public schools, youth sports programs, and gambling education and treatment programs. The Attorney General’s office has taken similar action this year against Kalshi, Coinbase, and Gemini.

The timing is not incidental. At the end of August, a U.S. appeals court said states have authority to regulate prediction markets, which weakened the sector’s argument that these products sit mainly under federal rules. For PSPs, acquirers, and banking partners, that means the licensing map is getting drawn state by state, and New York is not being subtle about where it stands.
