US court rules that Kalshi and Polymarket cannot suspend state-level litigation

According to the ruling of the US Federal Court of Appeals, the enforcement lawsuits against Kalshi and Polymarket in Nevada and Washington can continue to be pursued in state courts, rejecting the two companies' requests to suspend the case. The court held that the two companies failed to prove that the state court lawsuit would cause irreparable damage, nor did they prove that their claims of federal jurisdiction had a high likelihood of winning.
