Prediction market operator Kalshi faces at least US$36 billion in requested damages and penalties in a lawsuit filed by New York.
New York alleges Kalshi offered event contracts without a state gaming licence, including markets covering sports, elections and entertainment.
“You could copy and paste that lawsuit and file it against Nasdaq,” said Kalshi CEO Tarek Mansour.
New York also seeks US$100,000 per alleged unauthorised sports wagering offer, alongside restitution, disgorgement and civil penalties.
Kalshi moved the case to federal court about eight hours after filing, with the next dispute focused on federal jurisdiction.
Mansour claimed New Yorkers earned more than US$200 million on Kalshi in 2026, although he provided no supporting calculations.
A federal judge previously rejected Kalshi’s request to block New York gambling laws, while the CFTC supports federal oversight of registered derivatives exchanges.
A coalition of 38 state attorneys general has backed a lawsuit against Kalshi, arguing the platform violates state gambling laws by offering unlicensed sports betting contracts.
Massachusetts Attorney General won approval to file an amended lawsuit against Kalshi, adding allegations that the prediction markets platform targeted users under 21 while offering sports event contracts without a state licence.
