Kalshi Hit With Michigan Injunction and $500K Daily Penalty

Kalshi’s position in Michigan has gone from restricted to locked down. Attorney General Dana Nessel has secured a preliminary injunction against Kalshi, and the Michigan order forces the prediction market platform to keep blocking residents of the state from its sports event contracts. Breaking it carries a penalty of $500,000 per day. The order replaces the temporary restraining order issued in June and stays in force until the case reaches final judgment.

That last detail matters as much as the dollar figure. A temporary order expires on a calendar date, so a company can plan around it and wait it out. The Michigan injunction against Kalshi has no expiry date, and only a final judgment will lift it.

What Michigan’s Injunction Against Kalshi Blocks

The order covers the products the court treats as functionally identical to online sportsbook wagers. Moneyline contracts fall under it, along with parlay-style contracts, in-game markets and proposition-based contracts. If a licensed Michigan sportsbook would need approval to offer it, Kalshi cannot list it for anyone inside the state.

The restrictions reach well past the trading screen. Kalshi cannot accept deposits from Michigan residents or open accounts for users located there. It also cannot promote these products through applications, push notifications, influencers, affiliates or paid placements. That last clause pulls the affiliate and creator layer into the order, not just the platform.

Michigan Sets the Technical Standard

Geoblocking sits at the centre of the ruling, and the court did not leave the method up to the company. Kalshi has to use a third-party geolocation provider licensed by the Michigan Gaming Control Board, and that provider must meet the board’s technical requirements. Building something in house is off the table. The injunction leaves Kalshi one route to compliance in Michigan, and the state defined it.

Nevada showed why that specificity counts. Regulators there watched investigators log in from inside the state and buy restricted contracts months after a court had told the company to stop. Michigan wrote its order so compliance has a yes or no answer instead of an argument attached to it.

The Judge’s Reasoning

Judge Rosemarie Aquilina found that the state and its vulnerable residents faced immediate harm, describing the platform as a sports betting operation dressed up as an investment opportunity. Her order pointed to the gap in age limits as one concrete example. Michigan requires sports bettors to be at least 21, while Kalshi accepts users from 18.

The court also found that the company’s operations could sidestep consumer protections built into the regulated system. That includes the funding mechanisms routing gambling revenue back into schools, tribes and community programmes. Nessel echoed the point, saying the order protects residents from unlicensed practices and that her office will keep enforcing the state’s gaming laws.

Her March lawsuit set all of this up. It argues that Kalshi breached the Lawful Sports Betting Act by offering wager-like contracts without approval from the Michigan Gaming Control Board. The state’s case has never turned on what the company calls its products, only on how they behave.

Kalshi Lost the Venue Fight First

Before any of this, the company tried to change courtrooms. Kalshi moved to transfer the lawsuit to the U.S. District Court for the Western District of Michigan, where its federal argument would carry more weight. Nessel challenged the move, her motion to remand succeeded, and the case landed back in Ingham County Circuit Court.

That procedural loss shaped everything after it. State judges apply state gambling statutes, and Michigan’s are written broadly enough to capture contracts that function as bets. The Michigan injunction against Kalshi followed, so the company has now lost on the venue question and the substance of the case in the same courtroom.

A Fight With No Settled Answer

Kalshi’s defence has not shifted. The company maintains its contracts are financial products under Commodity Futures Trading Commission oversight, which in its view puts them beyond the reach of state gambling law. Courts elsewhere have split on that reasoning, and no ruling has settled the question yet.

This latest injunction adds weight to one side of the ledger without ending the argument. Kalshi keeps its federal case alive while absorbing the cost of a state order it cannot route around. Half a million dollars a day makes the choice between compliance and defiance simple to calculate, and other attorneys general now have a working figure to point at.
