New York Attorney General Letitia James has sued QCX LLC, doing business as Polymarket US, alleging that the federally regulated prediction-market operator is running an illegal gambling business in the state. The September 24 action seeks to stop Polymarket from offering unlicensed wagering in New York and recover restitution, disgorgement and substantial penalties. The case adds Polymarket to an expanding state-level challenge against prediction markets operating under federal commodities regulation.
According to New York’s official Polymarket petition, the state argues that event contracts involving sports, elections and other contingent outcomes satisfy its statutory definition of gambling because customers risk value on events outside their control. New York alleges that Polymarket operates without a Gaming Commission license despite offering products the state considers wagering. The complaint also invokes state penal and racing laws and alleges violations of the federal Wire Act.
New York Seeks Injunctions and Treble Penalties
The remedies extend well beyond a licensing order. The state asks the court to permanently bar unlicensed operations, require an accounting of wagers and customer losses, order restitution and disgorgement, and impose a penalty equal to three times Polymarket’s alleged gains. The petition separately seeks $100,000 for each unauthorized offer or attempted offer of sports or mobile sports wagering in New York.
Age restrictions form another part of the case. The Attorney General says Polymarket permits customers aged 18 to 20, while New York requires participants in mobile sports wagering to be at least 21. That allegation turns the dispute into both a jurisdictional question and a state consumer-protection case. Similar issues have already surfaced as Kalshi tightened its age-verification controls and New York previously brought prediction-market cases against Coinbase and Gemini.
Polymarket disputes the state’s legal theory. In a separate federal action filed the same day, the company argued that event contracts offered through its CFTC-regulated structure fall under exclusive federal oversight and that applying New York gambling law would conflict with the Commodity Exchange Act. Polymarket is asking a federal court to prevent state officials from enforcing those gambling provisions against its federally regulated activities.
Federal Preemption Becomes the Central Legal Question
The dispute reaches beyond whether particular contracts resemble conventional bets. The central legal question is whether federal commodities law preempts state gambling restrictions when a CFTC-regulated venue lists event contracts. Federal appellate courts have reached differing conclusions in related prediction-market litigation, increasing the significance of how courts treat the overlap between state gaming authority and federal derivatives regulation.
That tension has become increasingly visible across the sector. The CFTC continues to regulate market integrity at federally supervised venues, including recent guidance on manipulation risks in prediction-market “mention contracts”, while individual states are asserting separate authority over gambling access, licensing and age restrictions. Federal supervision and state gambling enforcement are therefore addressing different legal questions even when they apply to the same product.
Polymarket itself has been expanding its compliance infrastructure as it returns to the U.S. market, including tighter geographic restrictions documented in its recent geoblocking and KYC changes. Those controls do not resolve the underlying preemption dispute, because New York’s case challenges whether the products can lawfully be offered in the state at all without a gaming license.
The next concrete milestone will be the courts’ treatment of New York’s enforcement claims and Polymarket’s federal preemption request. No court has yet determined in these September 24 cases that Polymarket’s contracts are either illegal gambling under New York law or immune from state regulation under federal law. Until that happens, the filings establish competing legal positions rather than a settled regulatory boundary.
