Kalshi Moves NY $36B Gambling Suit to Federal Court

Kalshi’s CEO invoked Nasdaq and even compared the fight to Uber and Airbnb as the prediction-market operator pushed back on a sweeping New York lawsuit that seeks at least $36 billion in damages and penalties. What happened - On July 31 New York Attorney General Letitia James sued Kalshi, accusing the platform of offering event contracts—covering pro and college sports, elections and entertainment—without a New York State Gaming Commission license and thereby violating state gambling laws. The state’s verified petition asks for a permanent injunction, an accounting of customer activity, restitution, disgorgement, civil penalties and $100,000 per alleged unauthorized sports wager. Those are allegations, not court findings. - About eight hours after the filing, Kalshi removed the case to the U.S. District Court for the Southern District of New York, arguing the Commodity Futures Trading Commission (CFTC) oversees the exchange and federal law preempts state regulation of derivatives. - New York Supreme Court Justice Melissa A. Crane then treated the state’s preliminary injunction request as moot because the case was no longer in state court, a procedural development noted by gaming-law attorney Daniel Wallach. That ruling did not resolve the merits; if a federal judge remands the case, the state could refile its injunction request. CEO’s defense and broader argument - Kalshi CEO Tarek Mansour, in a CNBC interview on Aug. 3, rejected New York’s characterization of the platform as an “unlicensed sportsbook.” He said Kalshi is a CFTC-registered designated contract market where users take opposing positions and trade with each other while Kalshi matches orders and collects transaction fees—similar, he argued, to how Nasdaq operates. Mansour suggested New York could “copy and paste” the lawsuit and file it against Nasdaq, extending Kalshi’s defense to a broader view of event contracts as financial instruments rather than conventional wagers. - He also likened the regulatory fight to earlier battles faced by disruptors like Uber and Airbnb, framing New York’s action as incumbents pushing back against a new competitor. New York’s position and contested issues - The AG’s petition says Kalshi’s contracts let customers risk money on events beyond their control, meeting New York’s legal definition of gambling, and points to fees charged by Kalshi. The state also alleges people aged 18–20 accessed the platform despite New York’s 21+ minimum for mobile sports betting, and stresses state interests in licensing, consumer protections, tax collection and underage access. - The petition cites company-reported figures—a reported $22 billion valuation and $178 billion annualized transaction volume—and Kalshi’s claim that New Yorkers earned more than $200 million on the platform in 2026 and that the company could generate nearly $10 billion in state tax revenue over five years. Those numbers came from the filings or the company and have not been verified by a court. Regulatory backdrop and prior rulings - This removal to federal court follows earlier mixed rulings around Kalshi and similar products. On July 7, U.S. District Judge Analisa Torres denied Kalshi’s request to block the New York State Gaming Commission from applying state gambling law to its sports contracts, finding at that preliminary stage Kalshi hadn’t shown federal law displaced the state rules. Kalshi’s emergency appeals there were rejected. - The CFTC has taken the opposite position in federal court, arguing Congress granted it exclusive authority over swaps and contracts traded on registered derivatives exchanges. States counter that they retain traditional authority to police gambling within their borders. - Courts nationwide have been split: a federal judge in Washington blocked Kalshi sports contracts based on state gambling law applicability, while a Minnesota federal judge temporarily blocked that state’s ban on prediction markets. What’s next - The SDNY will now determine whether the case belongs in federal court. If the case is remanded, New York can renew its injunction motion in state court; if it stays in federal court, the dispute will be resolved alongside other questions about CFTC authority and federal preemption—an outcome with broad implications for prediction markets, derivatives platforms and possibly crypto exchanges that offer event- or outcome-based contracts. Why it matters to crypto and markets - The suit tests where the line is drawn between gambling and regulated derivatives—an especially consequential issue for platforms that list outcome-based contracts and for crypto firms that operate similar products. A federal ruling favoring Kalshi’s view could reinforce CFTC preemption claims and give momentum to exchanges treating those instruments as financial products; a state victory could empower states to apply gambling laws to a broader set of online markets. Bottom line Kalshi has framed the fight as a defense of a federally registered derivatives marketplace; New York says the products are gambling and must follow state licensing, tax and consumer protection rules. The forum fight now moves to federal court, where the decision on jurisdiction will shape how and where the bigger legal question—whether event contracts are state-regulated gambling or CFTC-governed derivatives—is ultimately decided.
