New York Attorney General Letitia James sued Kalshi on July 31, 2026, arguing the federally regulated prediction-market exchange is operating an illegal gambling platform in the state. The case puts a central industry question before the courts: whether event contracts listed on a CFTC-regulated exchange are derivatives protected by federal law or wagers subject to state gambling enforcement.
The lawsuit, filed in state court in Manhattan, seeks to block Kalshi’s New York operations and obtain restitution, forfeiture of profits and civil penalties. The Associated Press and The Block reported that New York court filings put the state’s claim at more than $36 billion, a figure that would create extraordinary exposure for a CFTC-registered prediction-market operator if the state prevails.
The New York case follows a separate federal ruling against Kalshi’s bid for early relief from state gambling regulators. In KalshiEX LLC v. Williams, No. 1:25-cv-08846, U.S. District Judge Analisa Torres denied Kalshi’s motion for a preliminary injunction on July 7, 2026. The ruling allowed the New York State Gaming Commission to continue treating Kalshi’s sports-related event contracts as subject to state gambling rules while the federal case proceeds.
What is New York alleging against Kalshi?
James’s petition alleges that Kalshi is offering event contracts that function as gambling products under New York law. Reuters reported that the attorney general’s office is targeting contracts tied to future events, including sports and elections, and is seeking an order that would stop Kalshi from offering those products in New York without state authorization.
New York’s theory is that users are risking money on uncertain outcomes outside their control, a structure the state says can fall within gambling law even when the contracts are listed on a federally regulated exchange. Reuters reported that James said the products can encourage problem gambling, including among people under 21. CNN reported that the attorney general’s office alleges Kalshi’s platform is open to users younger than New York’s legal age for mobile sports betting.
The attorney general’s case is separate from the New York State Gaming Commission dispute in federal court, but both proceedings turn on the same practical question. Kalshi says its contracts are regulated derivatives listed on a designated contract market overseen by the Commodity Futures Trading Commission. New York officials say federal registration does not turn sports and election event contracts into lawful gambling products under state law.
How did Judge Analisa Torres rule in Kalshi’s federal case?
Judge Torres’s July 7 order denied Kalshi’s request for a preliminary injunction against New York gaming officials. That did not decide the final merits of Kalshi’s preemption argument, but it kept state enforcement pressure in place while the case moves forward.
The New York Attorney General’s office and Gov. Kathy Hochul described the ruling on July 8 as a court victory against Kalshi. For state officials, the order supported their position that New York may continue applying gambling law to sports-related event contracts while the broader legal fight continues. For Kalshi and the prediction-markets industry, the ruling underscored the risk that state regulators can constrain access before appellate courts or the CFTC settle the national-market question.
The procedural posture matters. A preliminary-injunction ruling asks whether a plaintiff has met the standard for early court intervention, not whether the plaintiff will ultimately win. Still, in a fast-moving market, interim access decisions can shape the business reality long before a final judgment arrives.
What is the CFTC’s position on state gambling laws?
The CFTC has taken the position that state gambling regulators cannot force a registered derivatives exchange to violate federal obligations under the Commodity Exchange Act. The agency’s clearest recent action came on July 14, 2026, when it used Section 8a(9) authority after a Michigan state court order directed Kalshi to cancel certain executed trades involving Michigan residents.
In its July 14 release, the CFTC said Kalshi had to fulfill open trades under its normal practices. The commission cited the Commodity Exchange Act’s national-market structure and rules requiring transparent, nondiscriminatory access to designated contract markets. CFTC Chairman Michael Selig said then that “a state cannot force a DCM to violate its obligations, and federal law does not permit a DCM to discriminate against a state’s residents.”
That Michigan order did not resolve New York’s case, but it shows how the federal regulator is framing the broader dispute. The CFTC’s position is that a federally registered exchange cannot be required to deny access to residents of a particular state when doing so would conflict with federal derivatives law. States are pressing the opposite view: that federal derivatives registration is not a national sports-betting license.
Which states are involved in the preemption fight?
The Kalshi dispute has expanded well beyond New York. In its July 14 release, the CFTC said it had filed lawsuits against Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island and Wisconsin to protect the jurisdiction Congress assigned to the agency. The commission also said it had filed amicus briefs in the U.S. Court of Appeals for the Sixth Circuit, the U.S. Court of Appeals for the Ninth Circuit and the Massachusetts Supreme Judicial Court.
State attorneys general have pushed back in parallel. In an April 24 statement about a 38-attorney-general amicus brief supporting Massachusetts against Kalshi, James said Dodd-Frank was designed to regulate financial instruments, not authorize sports gambling nationwide. That argument has become the central state-law counterweight to the CFTC’s preemption theory.
The legal question is narrow but consequential: whether the Commodity Exchange Act preempts state gambling enforcement against event contracts listed by CFTC-regulated designated contract markets. If courts accept the CFTC’s view, exchanges such as Kalshi would have a stronger route to nationwide access. If states prevail, event-contract platforms may face state-by-state gambling restrictions even when their markets are listed under federal derivatives rules.
How does the New York City Council probe fit in?
Kalshi is also facing political scrutiny in New York City. The Wall Street Journal reported on August 13, 2026, that the New York City Council opened an investigation into Kalshi, Polymarket, Coinbase and Gemini Titan over marketing practices tied to prediction-market products.
The council inquiry is separate from James’s state-court lawsuit and from Kalshi’s federal case against New York gaming officials. According to the Wall Street Journal report, Council Speaker Julie Menin sent letters seeking information about the companies’ operations, earnings, marketing practices and compliance with consumer-protection laws. The New York Post also reported that the letters asked about New York-based users, revenue and advertising practices.
The city probe does not carry the same legal force as the attorney general’s lawsuit or a court injunction. It does, however, widen the political pressure on prediction-market operators at a time when state officials are arguing that the products resemble gambling and should be regulated under gambling law.
What happens next?
The immediate question is whether Kalshi can continue serving New York users while the state’s gambling-law claims and the federal preemption case proceed. The July 31 petition puts James’s illegal-gambling theory before a Manhattan state court. The federal docket, KalshiEX LLC v. Williams, No. 1:25-cv-08846, remains the main New York case testing whether state gambling rules must yield to the Commodity Exchange Act.
For the prediction-markets industry, the stakes reach beyond Kalshi. A ruling for New York would strengthen state efforts to police sports and election event contracts under gambling statutes. A ruling for Kalshi or the CFTC’s broader preemption theory would strengthen federally registered exchanges’ claim that event-contract markets should operate under one national derivatives framework rather than a patchwork of state gambling rules.
