New York Sues Polymarket; Company Files Federal Challenge
New York seeks gambling penalties against Polymarket US as the company brings the dispute into federal court.
New York sues Polymarket over alleged illegal gambling in a civil petition filed September 24, 2026, seeking to stop the company’s U.S. platform from operating in violation of state law. Polymarket responded by moving the enforcement case to federal court and filing a separate lawsuit to block New York’s action.
KEY FACTS AT A GLANCE
- Filed: September 24, 2026, in New York State Supreme Court, New York County.
- Defendant: QCX LLC, doing business as Polymarket US.
- State’s allegation: The platform offers gambling without a New York license.
- Company’s response: Removal to federal court and a separate federal challenge.
- Relief sought: An injunction, consumer restitution and financial penalties; the petition gives no aggregate amount.
Why New York sued Polymarket US
Attorney General Letitia James brought the proceeding on behalf of the People of the State of New York. Governor Kathy Hochul joined the announcement. The petition alleges that Polymarket’s event contracts amount to gambling and that the company lacks the New York State Gaming Commission license needed to offer it.
An event contract lets a customer take a position on whether a specified outcome will occur, with a payout determined by the result. The state challenges contracts tied to sports, elections and entertainment. Its case therefore reaches beyond the sports markets that have driven much of the wider prediction-market dispute.
New York also alleges gaps between Polymarket’s rules and the safeguards required of licensed mobile sportsbooks. According to the petition, the platform allows users aged 18 to 20, while New York requires mobile sports bettors to be at least 21. The petition also challenges wagers involving New York college teams, which it says state law prohibits.
“Our gambling laws exist to protect New Yorkers.”
— New York Attorney General Letitia James
The petition brings eight civil causes of action through Executive Law Section 63(12), including alleged violations of state gambling laws and the federal Wire Act. Those claims are allegations awaiting a court’s decision. This proceeding seeks civil relief and does not establish a criminal conviction.
The action follows New York’s earlier gambling case against Kalshi. It also adds to the state challenges facing prediction-market operators, including Wisconsin’s lawsuit naming Polymarket and other platforms.
What New York wants the court to order
The petition asks for a permanent injunction against the alleged unlawful conduct, an accounting of the money involved, restitution for consumers, disgorgement of gains and damages. These requests would address both future operations and money associated with past activity if the court grants them.
New York also requests a penalty equal to three times the gains from the alleged unlawful conduct and $100,000 for each unauthorized sports wagering offer or attempt, according to its petition. It separately seeks $2,000 in costs and prejudgment interest. The filing states no aggregate monetary demand, so those provisions do not establish a total bill.
Polymarket takes two different routes into federal court
Polymarket’s response created two proceedings in the U.S. District Court for the Southern District of New York. Keeping them separate is necessary to understand what a later filing or order would actually decide.
First, QCX filed a notice of removal on September 24. Removal transfers a proceeding from state court to federal court; the enforcement case now carries the caption James v. QCX LLC and number 1:26-cv-08338. QCX invokes federal-question and federal-officer grounds for removal. That filing is the company’s jurisdictional position, and moving the case does not dismiss New York’s claims.
Second, QCX filed its own federal lawsuit that day against James and New York gaming officials. The separate case, QCX LLC d/b/a Polymarket US v. James, is numbered 1:26-cv-08345. It asks for a declaration and preliminary and permanent injunctions preventing the state’s enforcement against the exchange.
That challenge rests on federal preemption: the argument that the Commodity Exchange Act displaces the state laws New York is seeking to enforce. For Polymarket, obtaining an injunction would provide protection against enforcement while the underlying dispute proceeds.
“We believe in New York and we’re staying here.”
— Neal Kumar, Polymarket chief legal officer, in a statement reported by Front Office Sports
Why CFTC registration has not resolved the dispute
The Commodity Futures Trading Commission’s registry lists QCX LLC, using the assumed name Polymarket US, as a designated contract market, with a designation date of July 9, 2025. That is its federal exchange status. It is central to the company’s defense and to the structure behind Polymarket’s U.S. return.
The contested question is what that status means for state gambling enforcement. New York seeks to apply its licensing and consumer-protection rules to the activity described in the petition. Polymarket argues that federal commodities oversight prevents the state from doing so. Each position has a practical consequence: whether the exchange must accommodate New York’s gambling restrictions or can operate under the federal framework it invokes.
The CFTC has also asserted federal authority through litigation. It sued New York on April 24, 2026, seeking to block state gambling enforcement against federally regulated prediction markets, part of its broader legal challenge to state regulation. The agency’s lawsuit states its position; it does not by itself settle which laws control.
Appellate decisions in other states show why a categorical answer would be premature. On April 6, the Third Circuit affirmed preliminary protection for Kalshi against New Jersey enforcement, accepting its likelihood of success on preemption. On August 28, the Ninth Circuit affirmed the dissolution of preliminary protection for Kalshi’s sports-event contracts in Nevada. Those decisions concern different proceedings and provide differing appellate analyses; neither is a judgment in New York’s Polymarket case.
What happens next for the cases and users
The immediate issues to watch are the federal court’s handling of the removed enforcement case and any decision on Polymarket’s request for preliminary protection in its separate lawsuit. A dispute over the proper forum, an interim injunction and a final decision on the claims would answer different questions. Each future order needs to be read for its actual scope.
No judicial order was identified in the public court feed checked on September 25, 2026, at 18:07 UTC. The lawsuit itself does not establish a court-ordered shutdown, a refund award or a finding that Polymarket violated the law. The available court records also do not verify every user’s current access to products or withdrawals.
For customers, the restitution request matters because it seeks money back for affected New Yorkers. It has not created an automatic refund entitlement or a claims process. Any eventual remedy would depend on what the court orders, including the conduct, customers and time period it covers.
Frequently asked questions
Why did New York sue Polymarket?
New York alleges that Polymarket US offers gambling without the required state license. Its civil petition challenges sports and other event contracts and alleges that the platform allows people aged 18 to 20 to participate despite New York’s 21-year minimum for mobile sports wagering.
Has a court banned Polymarket in New York?
New York has asked for an injunction. No judicial order was identified in the public court feed checked on September 25, 2026, at 18:07 UTC. That bounded check does not establish whether every product or account remains available.
Why are there two federal cases?
Polymarket removed New York’s enforcement proceeding to federal court, where it is James v. QCX LLC, case 1:26-cv-08338. It also filed a separate federal challenge, case 1:26-cv-08345, seeking to prevent New York officials from enforcing state gambling laws against it.
Does CFTC registration settle whether Polymarket can operate in New York?
QCX LLC is listed as a CFTC-designated contract market. Polymarket argues that federal commodities law prevents New York from applying its gambling laws to the exchange. New York disputes that position, and registration alone does not resolve the litigation.
Does the lawsuit target Polymarket US or its international platform?
The named defendant in New York’s petition is QCX LLC, doing business as Polymarket US. The case should be read as an action against that U.S. entity; its claims and procedural status should not automatically be applied to every Polymarket service worldwide.
Will New York users automatically receive refunds?
The petition requests restitution, which could involve returning money to affected consumers if ordered. Filing that request does not establish a refund entitlement or claims process. No restitution award was identified in the public court feed checked for this article.
