Michigan didn’t send a strongly worded letter. It sent a judge, a fourteen-day order, and a fine that started at $120,000 a day and grew from there. Every other Kalshi state page on this site describes an argument still underway — a lawsuit filed, a hearing scheduled, a bill introduced. Michigan is the one where a court has already ordered the sports-contract product turned off, at least for now, and the fight since then has been about whether Kalshi will actually comply.

The Order That Actually Stuck

Michigan has run licensed online sports betting since January 2021 under the Lawful Sports Betting Act, which Gov. Gretchen Whitmer signed in December 2019. The Michigan Gaming Control Board licenses around a dozen online sportsbook apps and taxes them at 8.4% of adjusted gross receipts. Kalshi has never applied for an MGCB license and doesn’t list sports contracts under one — it operates under its federal CFTC designation instead, the same argument it makes in every state. Attorney General Dana Nessel wasn’t satisfied with that answer. Her office sued Kalshi in March 2026, and on June 29, Ingham County Circuit Judge Rosemarie Aquilina granted a temporary restraining order: stop offering, advertising, or facilitating sports-related event contracts to anyone in Michigan, or pay $120,000 for every day the state has to keep asking.

The Michigan timeline, in order:

  • March 2026 — AG Dana Nessel sues Kalshi over unlicensed sports betting
  • June 29, 2026 — Judge Rosemarie Aquilina grants a TRO blocking sports contracts, $120,000/day fine for noncompliance
  • July 2026 — MGCB quits the National Council on Problem Gambling over its ties to Kalshi; CFTC issues an emergency order telling Kalshi to keep serving Michigan trades anyway
  • Order extended — geofencing deadline set for August 12, 2026, fine raised to $500,000/day for a miss
  • Kalshi says it dissolved pending Michigan trades to comply with the state order despite the CFTC’s directive

A Federal Agency Told Kalshi to Ignore the State Order

This is the part that doesn’t happen in the other states. After Judge Aquilina’s order, the CFTC didn’t just file a brief supporting Kalshi — it issued its own emergency order directing Kalshi to keep honoring Michigan trades, on the theory that a state court can’t reach into a federally designated exchange’s obligations to its users. Judge Aquilina’s order takes the opposite position, finding that Kalshi can follow both the state order and federal law at the same time without conflict. Kalshi, caught in the middle, told the court it dissolved the pending Michigan sports trades anyway. Two regulators, one company, one weekend’s worth of contracts, and no agreement between Washington and Lansing about who’s actually in charge.

Is Kalshi Legal in Michigan Right Now?

For sports event contracts specifically: no, not under the current order. The TRO is still a temporary order tied to ongoing litigation, not a final ruling that Michigan’s gambling law preempts Kalshi’s federal designation for good — but it’s an order with teeth, an August 12 compliance deadline, and a fine that quintupled once Michigan extended it. Kalshi’s non-sports markets (weather, economics, culture) aren’t named in the order, so the honest answer splits by product rather than covering the whole platform.

Don’t assume the geofence is live. An August 12, 2026 deadline is not the same as confirmed compliance by that date. Check the Michigan Gaming Control Board’s current public statements before assuming either that Kalshi has blocked Michigan or that it hasn’t — this is the fastest-moving legal status on this site.

What This Means If You’re in Michigan

Michigan already has a real, licensed, taxed sportsbook market — a dozen apps under the MGCB, running since 2021. Kalshi is the exchange a state court has ordered to stop offering sports contracts to Michigan residents while a federal agency tells it to keep going. That’s not a stable place to put money you care about, regardless of which regulator eventually wins. Trading event contracts isn’t a way to make income, and a contract can expire worthless no matter how the jurisdiction fight ends. 21+ only, and if it stops feeling like a choice, 1-800-GAMBLER is free and confidential.
