Is Polymarket legal in New York?

Is Polymarket legal in New York
New York sued Polymarket US nine months after it launched. Polymarket sued back within hours.
Short answer: Contested, and still running. On September 24, 2026 Attorney General Letitia James and Governor Kathy Hochul sued QCX LLC, the CFTC-designated exchange that trades as Polymarket US, in New York County Supreme Court for operating an unlicensed gambling business. Later the same day Polymarket sued James and other state officials in Manhattan federal court, asking a judge to declare that the Commodity Exchange Act puts its contracts beyond state gambling law. Neither court has ruled as of November 6, 2026, no injunction requires a geofence, and Polymarket US is available to New Yorkers aged 18 and over. The state’s parallel case against Kalshi is further along and has gone badly for the exchange: a federal judge rejected Kalshi’s preemption argument in July and the Second Circuit refused to intervene on November 3. Polymarket is making the same argument to the same courts.

Which Polymarket we are talking about

Two products carry the name. The original Polymarket settles in USDC on the Polygon blockchain and has been closed to US residents since its January 2022 settlement with the CFTC. The product New York sued is Polymarket US, which runs on QCX LLC, a designated contract market the CFTC designated on July 9, 2025 and Polymarket acquired later that year. Polymarket US launched in December 2025, according to the Attorney General’s release, and offers dollar-denominated event contracts, including sports, to US adults aged 18 and over. Our guide to Polymarket’s US legality covers the split in detail; this page is about New York’s response to the regulated version.

What New York filed

The petition, filed in New York County Supreme Court on September 24, 2026, names QCX LLC d/b/a Polymarket US and alleges that its markets are gambling under state law because the outcome is uncertain, outside the user’s control or dependent on chance; that Polymarket holds no licence from the New York State Gaming Commission and avoids the taxes licensed operators pay; and that it lets users aged 18 to 20 trade when New York’s mobile sports betting age is 21. The state asks for an order stopping Polymarket from operating as an unlicensed gambling business in New York, fines of three times the gains from the alleged conduct, forfeiture of those gains and restitution to users. Sports Betting Dime reports the petition also seeks $100,000 per offering or attempted offering.

James framed it as the same case she brought against Kalshi: “Our gambling laws exist to protect New Yorkers.” Hochul added that “nobody is above the law in our state.” The release points to Polymarket’s US marketing promise of “sports, followed by markets on everything.” The suit is the fourth New York has brought against a prediction market operator in 2026, after Coinbase and Gemini in April and Kalshi in July, and Hochul signed an executive order in April banning state employees from insider trading on platforms including Polymarket.

What Polymarket filed back

Hours later Polymarket sued James and other New York officials in Manhattan federal court, seeking declaratory and injunctive relief, including a preliminary and permanent injunction against enforcement of state civil and criminal gambling laws. Its argument is the industry’s standard one: QCX is a CFTC-designated exchange, the Commodity Exchange Act gives the Commission “exclusive jurisdiction” over contracts traded there, and Congress therefore preempted states from treating those contracts as bets. Polymarket’s counsel told the court that enforcement would expose it to “real and imminent risk” of civil and criminal liability and force it to stop operating in New York. No judge had ruled on the motion as of November 6, 2026, and the state case had produced no injunction.

Why the Kalshi file matters more than Polymarket’s own

Polymarket is the second exchange to make this argument to these courts, and the first did not win. Kalshi sued New York for a preemption injunction before the state sued it; Judge Analisa Torres of the Southern District denied the motion in July 2026, finding that New York’s gambling laws as applied to sports event contracts are not preempted by the CEA. New York then filed its $36 billion suit on July 31. In August the CFTC issued an emergency order under Section 8a(9) telling Kalshi to keep operating, which the Attorney General’s office called “irrelevant” in its filings. On November 3, 2026 a Second Circuit panel heard argument from Kalshi, Coinbase, the CFTC and counsel for New York and Connecticut, and the same day denied Kalshi and Coinbase an injunction pending appeal, saying they had “failed to make the required showing.” The merits appeal continues, but New York is free to pursue its state case in the meantime. Our Kalshi in New York page follows that case.

Polymarket’s federal suit sits in the same district under the same circuit precedent. Unless the Second Circuit reverses Torres on the merits, a different judge is unlikely to grant Polymarket what Kalshi was refused. The practical sequence to watch is therefore the Second Circuit’s merits decision, then whether New York moves for an injunction in the state court against Polymarket, as the state has been positioned to do against Kalshi.

The federal counterweights

Three federal moves cut the other way, none of them decisive yet. The CFTC sued New York in April 2026 seeking a declaration that it alone regulates event contracts on registered exchanges. New Jersey’s petition in New Jersey v. Kalshi, Supreme Court docket 26-299, asks the justices to resolve the split between the Third Circuit, which ruled for Kalshi, and the Ninth and Sixth Circuits, which ruled for the states; New York signed the 39-state brief urging the Court to take it. And on November 5, 2026 the CFTC issued an interpretation of its impartial access rule stating that exchanges may not restrict US traders by state and giving them 30 days to stop or explain; our report explains why that collides with court-ordered geofences rather than lifting them. If New York eventually wins an order requiring Polymarket US to block the state, the exchange will be caught between that order and its federal regulator, exactly where Kalshi already stands in Nevada, Michigan and Washington.

What this means in practice

A New Yorker aged 18 or over can open a Polymarket US account today, and a New Yorker aged 21 or over can bet with the state’s licensed mobile sportsbooks, which pay a 51 percent tax on revenue that Polymarket does not. Neither fact is a legal opinion. The first could change on any business day if the state court grants New York an injunction or the federal court denies Polymarket one and the company chooses to withdraw. Polymarket US also faces state pressure elsewhere, including Missouri cease-and-desist letters in September 2026 that named QCX among six operators, so a New York loss would not be an isolated event. Every dated action is in the change log, and the current map is in the state tracker. This page describes the regulatory position. It is not legal advice and not a recommendation to trade or wager anything.

Frequently asked questions

Is Polymarket legal in New York?

Contested. Attorney General Letitia James and Governor Kathy Hochul sued QCX LLC, which trades as Polymarket US, in New York County Supreme Court on September 24, 2026, alleging an unlicensed gambling business. Polymarket sued the state in Manhattan federal court the same day. As of November 6, 2026 no court has ordered Polymarket US to stop serving New York, so the app remains available.

What does New York accuse Polymarket of?

Running an illegal, unlicensed gambling operation: offering sports event contracts without a Gaming Commission licence, avoiding the taxes licensed operators pay, and letting users aged 18 to 20 trade when the mobile sports betting age is 21. The state seeks an order stopping the business, fines of three times the gains, forfeiture and restitution.

What is Polymarket’s defence?

That QCX LLC is a CFTC-designated contract market and the Commodity Exchange Act gives the CFTC exclusive jurisdiction over contracts traded on it, so New York’s gambling laws are preempted.

How is this different from the Kalshi case in New York?

New York sued Kalshi first, on July 31, 2026, seeking at least $36 billion. Kalshi lost its preemption motion before Judge Analisa Torres in July and on November 3, 2026 the Second Circuit refused Kalshi and Coinbase an injunction pending appeal. Polymarket’s federal case makes the same argument in the same district.

Is the original Polymarket available in New York?

No. The crypto-settled platform has been closed to US residents since a 2022 CFTC settlement. The only Polymarket product for New York users is Polymarket US, the entity New York sued.
