Prediction Market Laws. (2026, November 7). Michigan v. Kalshi Injunction (Sept. 1, 2026): The Order and Its $500,000-a-Day Penalty. https://predictionmarketlaws.com/documents/mi-v-kalshi-preliminary-injunction-order
Judge Rosemarie E. Aquilina barred Kalshi from offering or facilitating internet sports betting contracts to anyone in Michigan until the case is decided. The order also bans marketing those contracts to Michigan residents, requires geofencing through a provider licensed by the Michigan Gaming Control Board, and makes Kalshi send the order to every futures commission merchant that offers its sports contracts.
What the court decided
- No sports contracts. Kalshi may not offer, list, match, execute, clear, settle or otherwise facilitate internet sports betting contracts for anyone in Michigan or on any platform reachable from Michigan.
- No money or accounts. Kalshi may not take deposits or fees tied to those contracts from people in Michigan, or open, verify, fund or maintain accounts for trading them.
- No marketing. The ban covers websites, apps, email, push notifications, social media, influencers, affiliates and paid placements aimed at Michigan.
- No look-alikes. Kalshi may not launch functionally similar products, and the order lists single-game bets, parlays, teasers, moneylines, over-unders, in-game and proposition bets.
- Geofencing. Kalshi must use a third-party geolocation provider licensed by the Gaming Control Board that meets its 2024 technical standard, and owes $500,000 for each day the court finds it out of compliance.
- Notice to brokers. Within three business days Kalshi must give the order to every futures commission merchant offering its sports contracts.
Why it matters
Michigan's Attorney General moved on Sept. 29, 2026 to hold Kalshi in civil contempt over sports promotions sent to Michigan users after the order. A show-cause hearing is set for Nov. 24, 2026.
