Michigan Attorney General DANA NESSEL, acting on behalf of the state and the Michigan Gaming Control Board, secured a preliminary injunction against Kalshi on June 29, 2026. The order was issued by Ingham County Circuit Court Judge Rosemarie Aquilina. The available text does not specify the full scope of restrictions imposed beyond geofencing requirements.

State-level injunctions against CFTC-regulated platforms create a direct conflict between federal and state authority over event contracts, with implications for where Kalshi can operate and how other states may challenge similar platforms.
