Kalshi and Polymarket fail to stop lawsuits in Nevada and Washington that classify them as gambling

Kalshi and Polymarket have lost their bid to block gambling-related lawsuits filed by the states of Nevada and Washington. A panel of the U.S. Ninth Circuit Court of Appeals stated that federal derivatives regulation does not automatically shield prediction market platforms from enforcement of state gambling laws.The appeals court rejected the companies' request to halt the remand of the disputes back to state courts, with the judge stating that Kalshi and Polymarket failed to prove their claim that the cases fall under federal jurisdiction. This ruling deepens the legal divide over whether sports event contracts offered by prediction market companies are federally regulated derivatives or illegal gambling products under state law.
