Overview
Michigan’s Attorney General sued Kalshi on behalf of the Gaming Control Board in Ingham County. Judge Rosemarie Aquilina granted a temporary restraining order in June 2026, and on September 1, 2026 replaced it with a preliminary injunction that runs until final judgment. The order bars Kalshi from offering internet sports betting contracts to people in Michigan — expressly including “functionally similar” products such as parlays, moneylines, over-unders, in-game and prop contracts — and from taking deposits, advertising or opening accounts for them. It requires an MGCB-licensed geolocation provider, raises the penalty for failing that requirement to $500,000 a day from the TRO’s $120,000, and made Kalshi send the order within three business days to every futures commission merchant that offers its sports contracts.
The injunction is preliminary, not a merits judgment. The case was briefly in federal court: Kalshi removed it, Judge Paul L. Maloney remanded it on June 25, 2026, and Kalshi’s appeal of that remand order is in abeyance at the Sixth Circuit. (Caption confirmed via the filed complaint: Dana Nessel, Attorney General … on behalf of the People of the State of Michigan and the Michigan Gaming Control Board v. KalshiEX LLC, Ingham County 30th Judicial Circuit No. 26-1087-CZ.)

Ruling
Judge Aquilina replaced Michigan’s TRO with a preliminary injunction that runs to final judgment: sports contracts barred, a $500,000-a-day penalty for failing licensed geolocation, and notice to every broker that offers Kalshi’s sports contracts.
AG Dana Nessel sues Kalshi in Ingham County Circuit Court seeking a permanent injunction.
June 2026
Judge Aquilina grants a TRO with $120,000/day fines; CFTC directs Kalshi to honor pending Michigan trades.
September 1, 2026
Judge Aquilina replaces the TRO with a preliminary injunction: $500,000-a-day geolocation penalty, and notice to every FCM offering Kalshi’s sports contracts.
What's next: The state case proceeds in Ingham County under the injunction; no appeal of it has been reported. Kalshi’s separate appeal of the remand order (6th Cir. No. 26-1639) was held in abeyance pending the Tennessee/Ohio appeal, which the Sixth Circuit decided against Kalshi on September 25, 2026 — so a status report and the end of the abeyance come next. This injunction is also the trigger in Robinhood’s and Coinbase’s Michigan standstill orders.
