N.Y. attorney general sues Kalshi over illegal gambling markets
New York Attorney General Letitia James sued Kalshi on July 31, asserting the prediction market operates as an unlicensed gambling platform in violation of state law. The suit alleges underage access and lack of proper licensing, not wildfire betting markets, which Kalshi prohibits. James seeks to shut down Kalshi's New York operations. The case is part of a broader state-by-state challenge to the federal preemption argument that CFTC-registered platforms have relied upon.
New York's suit forces Kalshi and Polymarket into the same binary choice already imposed by Wisconsin, Utah, Connecticut, and Washington: geofence the state or risk voiding open contracts under local gambling law. Traders face contract validity that depends on geography, not federal label. The CFTC's emergency order keeps New York contracts live for now, but a permanent state injunction would void trades retroactively.
Legal spend now stacks across parallel cases in five jurisdictions and counting. New York joins Wisconsin and Utah in rejecting the preemption argument. Only Minnesota has recently sided with the platforms' federal-shield claim. The Second Circuit appeal remains the only path to a uniform national standard.
