Two lawsuits, one day, two completely opposite legal theories: on September 24, 2026, two separate complaints landed in Manhattan courts within hours of each other – one from New York against Polymarket, the other from Polymarket against New York. The Polymarket New York lawsuit is escalating into one of the most consequential legal test cases yet for the future of prediction markets in the United States.
New York Attorney General Letitia James and Governor Kathy Hochul accuse the platform of running an unlicensed gambling business for years, without the required license from the New York State Gaming Commission and without enforcing the age controls the state mandates for sports betting [1]. Polymarket, in turn, considers itself a federally regulated trading venue and is fighting back with its own federal lawsuit against exactly that interpretation [3].

Key Takeaways
- On September 24, 2026, New York sued QCX LLC (Polymarket US) in Manhattan State Court over unlicensed gambling [1].
- The state is seeking a shutdown of operations in New York, disgorgement of illegal profits, full user restitution, and penalties of up to three times those profits, plus up to $100,000 per sports contract [2][3].
- New York also alleges Polymarket allowed users aged 18 to 20 access to sports markets, even though the minimum age for mobile sports betting in New York is 21 [1].
- Polymarket Chief Legal Officer Neal Kumar called the lawsuit a “recycled lawsuit” and pointed to the company’s more than 350 employees in New York [2].
- The lawsuit is part of a broader New York campaign that already targeted Kalshi, Coinbase Financial Markets, and Gemini Titan; in parallel, the CFTC is suing New York to establish federal jurisdiction over event contracts.
What Exactly Is Polymarket Accused Of
At its core, New York alleges that Polymarket’s so-called “event contracts” – bets on the outcome of uncertain events like elections, sports results, or economic developments – are legally nothing more than classic gambling. Calling them a “prediction market” doesn’t change that, according to the complaint [4].
The central allegations can be summarized as follows:
- Missing license: Polymarket never obtained a license from the New York State Gaming Commission, even though one is mandatory for operating betting offerings in New York [1].
- Tax avoidance: Because the company operates unlicensed, the state is being denied tax revenue that licensed casinos and mobile sports betting operators must pay – funds that, according to officials, support public schools, youth sports programs, and problem gambling treatment [1][3].
- Access for minors: Users aged 18 to 20 reportedly had access to sports-related markets, even though the legal minimum age for mobile sports betting in New York is 21 [1].
James’ office describes the situation as exposing New Yorkers to “serious personal and financial risk,” because unlicensed platforms bypass the consumer protection mechanisms that apply to regulated sports betting providers [1].
The Demands in Detail
The complaint filed in Manhattan State Court seeks several court orders at once. The table below summarizes the main demands:
| Demand | Description |
|---|---|
| Operating ban | Court order for immediate cessation of business in New York |
| Profit disgorgement | Full surrender of all profits deemed illegal |
| User restitution | Full repayment to affected New York users |
| Civil penalty | Up to three times the illegal profits |
| Additional fines | Up to $100,000 per individual unauthorized sports contract offering [2][3] |
This combination of an operating ban, restitution, and potentially very high fines makes clear that New York isn’t just sending a symbolic signal – it intends to actually stop a business model that officials say systematically violates existing gambling law.
Polymarket’s Response: Recycled Lawsuit and Its Own Federal Suit
Polymarket Chief Legal Officer Neal Kumar responded immediately and firmly. He stressed that the company was founded in a small New York City apartment and now employs more than 350 people in the city. He said the company would “fight for our users” and called the lawsuit a “recycled lawsuit” – a repeat of a legal pattern New York had already applied against other platforms [2].
“We were founded in a tiny NYC apartment and now employ more than 350 people in New York.” – Neal Kumar, Chief Legal Officer, Polymarket [2]
Notably, Polymarket didn’t stop at defense. On the same day, the company filed its own lawsuit in federal court in Manhattan, directed at Attorney General James and other representatives of New York State. The goal of this countersuit is to prevent the state from regulating Polymarket’s U.S. prediction market business at all. The argument: the platform is an exchange subject to the federal Commodity Exchange Act and therefore falls primarily under the oversight of the Commodity Futures Trading Commission (CFTC), not the gambling laws of individual states.
This dual litigation strategy – defense in state court plus a counterattack in federal court – shows that Polymarket deliberately wants to elevate the conflict to a fundamental jurisdictional question, rather than merely defending against individual allegations.
Part of a Bigger Campaign: New York’s Crackdown on Prediction Markets
The Polymarket New York lawsuit is by no means an isolated case. It’s the latest piece of a systematic campaign by the state against providers of event contracts and prediction markets. The timeline shows a clear pattern:
- April 2026: New York sues Coinbase Financial Markets and Gemini Titan over similar allegations related to prediction market offerings.
- July 2026: New York files suit against Polymarket’s direct competitor Kalshi, on the same legal grounds later used against Polymarket [2].
- September 2026: Lawsuit against QCX LLC / Polymarket US over unlicensed gambling.
This sequence makes clear that New York is pursuing a consistent legal theory: regardless of the marketing language – “event contract,” “prediction market,” or “derivative” – these are bets on uncertain events, subject to classic gambling law and therefore requiring a Gaming Commission license [3][4].
The Counterweight: CFTC vs. New York in Federal Court
While New York pursues individual platforms at the state level, the Commodity Futures Trading Commission (CFTC) is pursuing the opposite strategy at the federal level. Since April 2026, the CFTC has been suing New York State in the U.S. District Court for the Southern District of New York.
The CFTC’s goal is to have a court declare that exclusive federal jurisdiction applies to event contracts. This is meant to prevent individual states from enforcing their own gambling laws against exchanges already registered with the CFTC. CFTC Chairman Michael S. Selig described this as an “onslaught of state lawsuits” – a wave of state litigation that, in his view, undermines uniform federal regulation of derivatives markets.
This creates an unusual situation: two levels of government – a state and a federal agency – are suing each other over the basic question of who has jurisdiction at all, while private companies like Polymarket and Kalshi get caught in the crossfire.
Why This Dispute Goes Beyond a Single Case
The significance of the Polymarket New York lawsuit lies less in the specific fine amounts than in the fundamental legal question it raises: are prediction markets financial instruments subject to federal CFTC oversight, or are they functionally gambling offerings subject to the individual laws of U.S. states?
The answer determines whether platforms like Polymarket or Kalshi can operate across all 50 states under a single federal authorization in the future, or whether they must obtain licenses state by state, like traditional sports betting operators. For the entire prediction markets industry, which has grown rapidly since Polymarket’s U.S. platform launched in December 2025, this is an existential question.
For observers in Germany following the regulation of crypto-adjacent financial products, the case is a vivid example of just how unsettled the legal classification of new digital market formats in the U.S. remains – similar to the failed Clarity Act crypto regulation in the U.S. Senate – and how much this ambiguity depends on which level of jurisdiction ultimately has the final word.
What Happens Next
As of September 24-25, 2026, both lawsuits – New York’s state case and Polymarket’s federal suit in Manhattan federal court – are newly filed and unresolved. No court has yet ruled on whether Polymarket must actually cease operations in New York or apply for a state gambling license.
Observers expect the further development to depend heavily on how the federal court rules in the CFTC’s case against New York. If that court rules in favor of clear federal jurisdiction over event contracts, it could strengthen Polymarket’s position in its own federal lawsuit. Conversely, a ruling favoring the states would bolster New York’s position in its case against Polymarket and could encourage other states to take similar action.
Conclusion: A Precedent With an Open Outcome
The Polymarket New York lawsuit is more than a single legal dispute between a state and a crypto-adjacent company. It exemplifies the unresolved jurisdictional conflict between state gambling law and nationwide financial market regulation in the U.S. As New York consistently continues its campaign against prediction market providers – after Coinbase, Gemini, and Kalshi, now also Polymarket – the CFTC is simultaneously fighting to establish uniform federal jurisdiction over event contracts.
For readers in Germany following the European crypto and financial markets, the case offers a vivid illustration of how fragmented and fluid the regulation of new digital market formats in the U.S. remains. Anyone following prediction markets closely should watch the development of this case, along with the parallel CFTC case against New York, closely in the coming months, since both decisions could have signal effects far beyond the Polymarket case for the entire industry.
