New York’s attorney ​general sued Polymarket on Thursday, escalating her ‌battle against prediction markets, an industry that she says violates state laws against illegal gambling.

Attorney General Letitia James ​filed her petition nearly two months after ​bringing a similar case against Polymarket rival Kalshi. ⁠She filed similar petitions in April against two other ​prediction market operators, Coinbase Financial Markets and Gemini ​Titan.

James’ case against Polymarket is the latest effort by US states to crack down on an industry that has ​soared in popularity since faring better than ​pollsters in predicting that Republican Donald Trump would beat Democrat Kamala Harris ‌in ⁠the 2024 presidential election.

Those states are also at odds with the Trump administration, with the Commodity Futures Trading Commission claiming exclusive authority to regulate ​prediction markets.
