NY sues Kalshi over alleged unlawful playing operation as prediction market warfare heats up

New York on Friday sued Kalshi, accusing the federally regulated prediction market operator of running an illegal gambling business in the Empire State in the latest legal challenge to at least one of the nation’s hottest startups.

As The Post completely reported Friday, the rivalry between the two firms has become increasingly vicious behind the scenes, with Polymarket CEO Shayne Coplan allegedly referring to Kalshi as a “copycat,” circulating unsubstantiated private rumors about Kalshi co-founders Tarek Mansour and Luana Lopes Lara and rising more and more annoyed as Kalshi surpassed Polymarket in trading quantity.

“States can’t just shut down a federally licensed exchange. This would also hurt New Yorkers, who would be driven offshore.”

Gov. Kathy Hochul and James countered that Kalshi has ignored New York’s gaming legal guidelines by failing to acquire a license from the New York State Gaming Commission while sidestepping taxes and shopper safety guidelines that apply to casinos and cell sportsbooks.

The criticism follows a separate setback for Kalshi earlier this month, when a New York choose ruled the company couldn’t block state gaming regulators from overseeing its sports activities prediction markets, even as the company has scored victories elsewhere arguing that federal law preempts state playing laws.
