New York Attorney General Letitia James filed a verified petition in New York County Supreme Court on July 31, 2026, seeking penalties and other remedies from KalshiEX LLC that could total $36 billion, plus a court order blocking the prediction-market exchange from operating in the state. The case escalates the fight over whether federally regulated event-contract exchanges must also comply with state gambling laws.
The filing followed U.S. District Judge Analisa Torres’ July 7, 2026 ruling in KalshiEX LLC v. Williams that New York gambling laws, as applied to Kalshi’s sports-event contracts, are not preempted by the Commodity Exchange Act. The Commodity Futures Trading Commission is separately pressing its own federal challenge to New York’s authority over CFTC-regulated prediction markets, a case the agency filed on April 24, 2026.
What did New York accuse Kalshi of doing?
New York’s petition names KalshiEX LLC as a defendant and accuses the company of operating an unlicensed gambling business in violation of the New York Constitution and state law. The state’s central theory is that Kalshi lets customers risk money on uncertain events outside their control, which New York says falls within its legal definition of gambling.
The petition alleges that Kalshi has not obtained a license from the New York State Gaming Commission, has not paid taxes associated with state-regulated wagering, and has allowed users ages 18 to 20 to trade on the platform even though New York requires mobile sports-betting participants to be at least 21. Those allegations put the case at the intersection of financial-market regulation, sports betting, consumer protection and federal preemption.
James framed the suit as an enforcement action against an operator that New York views as functionally equivalent to a gambling platform. In an April 24 statement joining an amicus brief in the Massachusetts case against Kalshi, the New York Attorney General’s office said Kalshi’s sports event contracts should be subject to state gambling laws. After the July 7 ruling against Kalshi in federal court, James and Governor Kathy Hochul said in a joint statement that New York would continue to hold prediction markets accountable under state gambling rules.
How does the $36 billion demand work?
The $36 billion figure reflects the remedies New York is seeking, not a damages award already entered by a court. The Associated Press reported that James’ office is seeking repayment to customers, disgorgement of gains tied to New York activity, and civil penalties tied to allegedly illegal bets. The Wall Street Journal also reported that the state’s requested penalties could reach $36 billion.
That amount would make the New York case one of the largest state-level enforcement threats yet facing the prediction-market industry. It also broadens the practical risk for exchanges beyond sports contracts alone. The petition seeks a court order against Kalshi’s operations in New York, while the state’s earlier October 2025 cease-and-desist letter to Kalshi, cited in Judge Torres’ July order, focused on an unlicensed mobile sports-wagering platform connected to sports events.
The size of the request does not decide the legal question. Kalshi can contest liability, the availability of particular remedies and the measure of any penalties. For the industry, the more important issue is whether New York can use gambling law to restrict a CFTC-designated contract market’s event contracts inside the state.
What did Judge Torres rule on Kalshi’s preemption argument?
Judge Torres denied Kalshi’s request for a temporary restraining order and preliminary injunction on July 7, 2026, in KalshiEX LLC v. Williams, case number 25 Civ. 8846 in the Southern District of New York. The amended opinion and order, posted by the court on July 13, said Kalshi had not shown a likelihood of success on its claim that the Commodity Exchange Act preempts New York’s gambling laws as applied to its sports-event contracts.
The court described Kalshi as a CFTC-certified designated contract market and noted that Kalshi began listing several sports-event contracts on January 22, 2025. The order also cited the New York State Gaming Commission’s October 24, 2025 letter directing Kalshi to stop operating, advertising or otherwise making available an unlicensed mobile sports-wagering platform in New York in connection with sports events.
Kalshi argued that its contracts are subject to exclusive federal oversight because they trade on a CFTC-regulated exchange. New York argued that sports-event contracts fall within the state’s gambling authority. Judge Torres sided with New York at the preliminary-injunction stage, writing that New York gambling laws, as applied to Kalshi’s sports-event contracts, are not preempted by the CEA.
The ruling did not end the case. It denied emergency relief and allowed New York’s position to stand while the litigation continues. For other prediction-market operators, the order matters because it rejected a broad preemption theory that exchanges have also raised in fights with other state gaming regulators.
What is the CFTC’s separate case against New York?
The CFTC filed a federal lawsuit against New York on April 24, 2026, seeking to assert the agency’s jurisdiction over prediction markets. Bloomberg Law reported that Governor Hochul was named as a defendant in that action, which is part of a wider CFTC campaign against state attempts to regulate event contracts through gambling law.
The agency described that campaign in an April 28, 2026 statement announcing a separate lawsuit against Wisconsin. The CFTC said Congress gave it exclusive jurisdiction over derivatives including event contracts traded on designated contract markets. The agency said some states had tried to regulate prediction markets through state gambling laws and said it had filed lawsuits against Connecticut, Illinois and New York, along with other filings in appellate courts.
That federal position is broader than Kalshi’s own dispute with New York. If courts accept the CFTC’s view, state gaming regulators would have less room to enforce sports-betting or gambling rules against federally registered prediction-market exchanges. If courts reject it, exchanges may need to navigate both CFTC oversight and state gambling regimes, especially for sports contracts.
How did Kalshi respond to New York’s lawsuit?
Kalshi rejected New York’s theory and defended its federal status. Elisabeth Diana, Kalshi’s head of communications, told the Associated Press that states cannot shut down a federally licensed exchange. That response tracks the legal argument Kalshi has made in court, namely that CFTC registration limits state authority over event contracts listed on its exchange.
The company’s position carries a clear commercial stake. Kalshi’s model depends on being able to list event contracts nationally under federal commodities law. State-by-state gambling enforcement would make that model more fragmented, especially in large sports-betting markets with active gaming regulators.
New York’s position carries its own state-law stakes. The state argues that platforms taking money on sports and other uncertain events should follow the same licensing, age, tax and consumer-protection rules that apply to regulated gambling businesses. That is why the case has moved beyond a narrow dispute about one company’s product design and into a larger test of who sets the rules for retail event contracts.
Why does the sports-contract fight matter beyond New York?
Sports contracts are the pressure point because they look most like the activity state gambling laws already regulate. Judge Torres’ July order focused on Kalshi’s sports-event contracts and New York’s authority over sports wagering, while the attorney general coalition that James joined in April argued that states are best positioned to regulate sports betting and related consumer risks.
The broader prediction-market industry has grown around the claim that event contracts are financial instruments traded on regulated exchanges, not wagers booked by sportsbooks. State regulators have challenged that framing when contracts reference sports outcomes, arguing that the economic substance is betting even if the market structure differs from a conventional sportsbook.
That distinction will matter for other platforms as well. The CFTC’s April 28 Wisconsin release said the state had sued Kalshi, Polymarket, Crypto.com, Robinhood and Coinbase in connection with prediction-market activity. The agency’s decision to sue multiple states signals that it sees the issue as an institutional challenge to federal derivatives oversight, not only as a dispute over Kalshi.
Which court milestone matters next?
The next meaningful milestone is how courts reconcile the July 7 Southern District of New York ruling with the CFTC’s April 24 federal lawsuit against New York. Judge Torres has already rejected Kalshi’s preemption argument at the preliminary-injunction stage in KalshiEX LLC v. Williams. The CFTC is asking federal courts to endorse a broader jurisdictional theory that would restrict state enforcement against CFTC-regulated prediction markets.
For Kalshi, the immediate risk is state enforcement in New York while its federal litigation continues. For the CFTC, the risk is a patchwork of state rulings that weakens its claimed authority over event contracts. For New York, the case is a test of whether its gambling laws can reach a federally regulated exchange when the contracts resemble sports betting or other wagers offered to retail customers.
The outcome will shape more than one company’s access to one state. It will help determine whether prediction markets can scale under a primarily federal rulebook, or whether sports and other event contracts must be built around state-by-state gaming law in the same way online sportsbooks operate today.
