New York officials sued prediction market platform Kalshi for potentially billions of dollars on Friday, calling it an “illegal, unlicensed gambling operation” that includes sports wagering as the state seeks to halt its operations and force the company to forfeit its profits.
New York joins a growing number of states filing lawsuits against Kalshi and other companies in a dispute with President Donald Trump’s administration over who regulates the fast-growing prediction market. Kalshi and other platforms argue they are federally licensed and regulated, and states have no authority to govern them.
“It’s sad to see this type of political theater from the leadership in our own state,” Elisabeth Diana, a spokesperson for New York-based Kalshi, said in a statement. “States can’t just shut down a federally licensed exchange. This would also hurt New Yorkers, who would be driven offshore. We love New York, we love New Yorkers, and New Yorkers love our product.”
Prediction market platforms like Kalshi and Polymarket allow trading on the likelihood of a wide range of events such as sports, politics, news and even the weather.
