An Ingham County court granted Michigan Attorney General Dana Nessel a preliminary injunction against Kalshi, announced on 2 September 2026. It requires Kalshi to maintain geofencing that keeps Michigan residents and anyone inside the state away from its sports contracts, with a $500,000 fine for each day of violation. A temporary restraining order had already halted the sports markets in June.
