New York has sued Polymarket, accusing the prediction-market operator of running an unlicensed gambling business and asking a state court to stop the company from operating in New York unless it obtains the required gaming licenses.
Attorney General Letitia James and Governor Kathy Hochul announced the action on September 24 against QCX LLC, which operates as Polymarket US. The New York Attorney General’s office alleges that Polymarket’s event contracts meet the state’s legal definition of gambling because users stake money on uncertain future events outside their control.
The lawsuit seeks an injunction preventing Polymarket from continuing to operate an unlicensed gambling business in New York, along with restitution, disgorgement and financial penalties. The state is also seeking penalties equal to three times the gains it alleges Polymarket generated through unlawful activity and $100,000 for each unauthorized offer or attempted offer of sports wagering in the state.
The complaint argues that Polymarket has marketed sports contracts to New Yorkers while lacking a license from the New York State Gaming Commission. It cites markets involving professional sports, college games, elections and entertainment events.
New York also alleges that the platform is available to customers between 18 and 20 years old, while state law requires participants in mobile sports betting to be at least 21.
James said the state’s gambling rules are intended to protect consumers and provide tax revenue for public programs. Hochul separately accused Polymarket of putting younger users at risk by operating outside the state’s licensed gambling framework.
Those are allegations made by New York and have not been established by a court.
Polymarket has rejected the state’s characterization. Chief Legal Officer Neal Kumar said the company had attempted to engage directly with officials and described the decision to sue as disappointing. He said Polymarket intends to fight for its users and remains willing to discuss consumer protections with the attorney general’s office.
Polymarket Is Federally Regulated, but New York Says That Is Not Enough
The lawsuit goes directly to the central legal dispute surrounding U.S. prediction markets: whether federally regulated event contracts fall primarily under the Commodity Futures Trading Commission or can also be subjected to state gambling laws.
QCX LLC, operating as Polymarket US, is a CFTC-designated contract market. That federal status sits at the center of the industry’s argument that prediction markets are derivatives exchanges rather than conventional sportsbooks.
States increasingly disagree.
New York sued Kalshi in July over similar allegations and previously brought actions against prediction-market offerings from Coinbase and Gemini. Elsewhere, courts have reached conflicting conclusions over how far federal commodities law prevents states from enforcing their own gambling rules.
The divide became particularly visible when Kalshi lost a major Nevada appeal in August. The Ninth Circuit concluded that Kalshi had not shown that federal law prevented Nevada from applying its gaming laws to sports contracts. That decision conflicted with an earlier Third Circuit ruling that had favored Kalshi in its dispute with New Jersey.
The CFTC itself has pushed back against state intervention in some cases. Dave Finances previously reported how the CFTC challenged Michigan’s effort to interfere with Kalshi contracts, illustrating how aggressively the federal-state jurisdictional dispute has developed.
The conflicting rulings mean the broader question remains unresolved and could ultimately require Supreme Court review.
New York Is Targeting the Sportsbook-Like Side of Polymarket
The details of New York’s complaint matter because Polymarket increasingly looks different from the crypto-native prediction platform that first became prominent through election and political markets.
Its U.S. expansion has pushed heavily into sports.
Polymarket has built partnerships with major sports-data providers and leagues, adding live data, streaming and market-integrity infrastructure. A recent expansion of its Sportradar partnership extended coverage across more than 20 leagues and competitions involving roughly 300,000 matches annually.
That commercial strategy is attractive because sports provide a constant stream of events and repeat trading opportunities. It also makes the distinction between a prediction exchange and a sportsbook harder to explain to state regulators.
New York’s argument is essentially functional: if customers are putting money on whether one team beats another and receiving a payout based on the result, the state says the activity falls under gambling law regardless of whether the product is described as an event contract.
Polymarket and the wider prediction-market industry take a different view, emphasizing that these products trade as federally regulated contracts on CFTC-supervised exchanges.
This Case Could Change the Economics of Prediction Markets
The immediate risk for Polymarket is straightforward. If New York succeeds, the company could be forced to stop serving users in one of the largest U.S. markets unless it complies with the state’s gambling regime.
The bigger risk is precedent.
The prediction-market business model becomes much more complicated if federal exchange registration does not provide a single nationwide regulatory framework. Conventional sportsbooks already operate state by state, dealing with separate licenses, tax rates, age restrictions and product rules.
Prediction exchanges have potentially avoided much of that fragmentation by operating within federal commodities regulation.
If more courts accept the states’ position, that advantage could narrow considerably.
It would affect more than legal expenses. State gaming taxes can be substantial, product availability can differ by jurisdiction and compliance systems must determine exactly where users are located and which contracts they are allowed to trade.
For a platform trying to build national liquidity, fragmented access is particularly awkward. Prediction markets become more useful as more traders participate in the same contracts. Breaking that liquidity into different state regimes can make pricing less efficient and increase operating costs.
Polymarket’s Growth Makes Regulatory Friction More Expensive
The legal challenge arrives while Polymarket is expanding quickly and attracting significant institutional attention.
That growth has also brought operational scrutiny. Earlier this month, Dave Finances reported that Checkout.com rejected more than 80% of Polymarket deposits during a February fraud attack, after criminals allegedly attempted to use stolen debit cards to fund accounts.
The company subsequently strengthened fraud controls, but the episode illustrates why regulatory questions become more consequential as a financial platform scales.
For Polymarket, the New York lawsuit now adds state gambling law to a growing list of issues that management must address while expanding its U.S. business.
The important question is no longer simply whether prediction markets can attract users. They clearly can.
The question is which regulatory structure will govern them once they become large enough to compete directly with sportsbooks, exchanges and other established financial platforms.
New York’s case will not settle that national debate on its own. Different courts are already producing different answers, while the CFTC continues to assert a significant federal role.
But the lawsuit raises the stakes. If New York can successfully treat Polymarket’s sports contracts as gambling despite the platform’s federal exchange status, other states will have a stronger model for pursuing similar cases.
If Polymarket successfully defeats the challenge, prediction exchanges would gain support for the argument that a federally regulated market can operate without rebuilding the traditional sportsbook licensing structure state by state.
That is why this lawsuit matters beyond Polymarket. The eventual outcome could help determine whether U.S. prediction markets develop as a national derivatives industry or as something much closer to the fragmented state-by-state sports betting market they have spent years arguing they are not.
