US Court Blocks Kalshi Tribal Bets

A federal appeals court blocked Kalshi from offering sports event contracts on tribal lands in the United States, handing the prediction market platform its second legal defeat in a month. The 3-0 ruling by the 9th U.S. Circuit Court of Appeals upholds tribal sovereignty over gaming regulations. The decision heightens regulatory uncertainty for electronic brokerages like Robinhood Markets Inc - A, which routes customer event trades through Kalshi.
