Woofun AI reports that the CFTC has intervened in a dispute between a Michigan court and prediction market firm Kalshi, issuing an order prohibiting the company from canceling client transactions. The commission asserts exclusive regulatory authority over Kalshi as a Designated Contract Market, warning that reversing executed trades undermines contract certainty. This follows a June ruling by a Michigan district court ordering Kalshi to halt local sports betting operations. On July 2, Kalshi sought CFTC permission to refund affected users, but the regulator rejected the move as unprecedented.
