New York state filed a lawsuit on Thursday against Polymarket, a popular prediction market platform, accusing it of operating an unlicensed gambling business and seeking a court order to block it from the state. Governor Kathy Hochul said the company had "put New Yorkers at risk," particularly minors vulnerable to problem gaming, and officials are pursuing fines and user restitution. Polymarket — which allows users to trade contracts tied to the outcomes of events such as elections and sports, similar in structure to financial markets — has vowed to fight the case, with its chief legal officer stating the company believes in New York and intends to stay.
