SHORT ANSWER

Contested. Kalshi publishes no state list that names Montana, and none of the sources we checked bars it there. Montana has acted against Kalshi: d. Mont. (Judge Molloy) denied Kalshi's motion for a preliminary injunction without prejudice and lifted the stay in KalshiEX v. Knudsen (6:26-cv-28).
