A U.S. federal appeals court rejected Kalshi v. Polymarket's request to suspend state-level litigation.

According to Huoxun Finance, a U.S. federal appeals court ruled that enforcement lawsuits filed by Nevada and Washington states against prediction market platforms Kalshi and Polymarket can continue in state courts, rejecting the companies' requests to suspend the cases during their appeals. The court held that the two companies failed to demonstrate that the state court proceedings would cause irreparable harm, nor did they demonstrate a high probability of success for their claims of federal jurisdiction.
