Michigan Orders Kalshi to Geofence Sports Bets or Face Fines

An Ingham County judge has given prediction-market operator Kalshi until the end of 12 augusti 2026, to wall Michigan off from its sports contracts — or start paying $500,000 for every day it fails to comply. The order sharply escalates a penalty that began at $120,000 a day and cements Michigan as the second state, after Nevada, to force Kalshi’s sports markets offline.

Judge Rosemarie Aquilina of the Ingham County Circuit Court extended the temporary restraining order she first signed on 29 juni 2026, when she ruled that Kalshi’s sports event contracts amount to unlicensed sports betting under Michigan law. Rather than let the two-week ban lapse, she kept it in force and gave Kalshi a 30-day window to install geolocation controls, warning that progress has to be steady rather than saved for the final days.

The stakes for Kalshi run well beyond one state. The company’s business depends on broad national access and deep liquidity, and a state-by-state wall chips away at both. If Michigan makes its ban stick, other states weighing the same fight get a working template.

Why geofencing is the pressure point

Geofencing is the crux because it is the step Kalshi has resisted hardest. After the June ruling, the court briefly let the company block Michigan customers by account address while it argued its case. That lighter measure left an obvious gap: someone who registered out of state can still trade sports contracts while physically inside Michigan.

At the recent hearing, Kalshi’s lawyers said true geolocation is a heavy lift. They argued that the work with location provider GeoComply requires extensive testing to satisfy federal rules and could not give the court a firm completion date. The state was unconvinced. Assistant Attorney General Lauren Fitzsimons argued that Kalshi has a financial reason to stall, pointing to roughly $30 billion in trading volume over the previous 30 days as the FIFA World Cup drove record activity.

A GeoComply executive told the court that geofencing projects are usually finished in one to two weeks, with most of the wait sitting on the customer’s side. Aquilina settled on 30 days as the balance between that technical reality and consumer-protection concerns, and made clear the ban itself was not up for debate. As she put it, “Gambling regulation is within the realm of Michigan,” adding that Kalshi could follow both state and federal law and simply had not complied with the state’s.

How Michigan got here

The case traces back to mars 2026, when Michigan Attorney General Dana Nessel sued Kalshi on behalf of the Michigan Gaming Control Board, alleging the New York company was running an online sportsbook dressed up as event trading without a state license. Kalshi tried to move the fight to federal court; Nessel won a motion sending it back to state court, and then secured the restraining order in late June.

The Gaming Control Board has framed the dispute as consumer protection rather than turf. In its response to the order, the board said licensed Michigan sportsbooks must verify that bettors are at least 21, offer self-exclusion and deposit limits, and protect customer funds — safeguards it says Kalshi provides none of. Executive Director Henry Williams argued that whether the product is called an event contract or a trade, it is a sports wager offered to residents without a license.

A widening front against prediction markets

Michigan is one battle in a national fight over who regulates prediction markets. Kalshi and rival platforms argue their contracts are federally regulated financial products overseen by the Commodity Futures Trading Commission, putting them beyond the reach of state gambling law. States counter that a sports wager is a sports wager whatever it is called. Courts have split, and the question is widely expected to reach the U.S. Supreme Court.

That pattern is now visible across the map. In Nevada, regulators say Kalshi relied on address-based blocking and later its own geolocation system, which they argue still lets residents through, and they have asked a court to hold the company in contempt. In Massachusetts, a ban is on hold while Kalshi appeals. A federal judge in New York recently declined to shield Kalshi from that state’s gambling laws. The pushback also reaches overseas, where the Czech Republic just blocked rival Polymarket as unlicensed gambling.

For now, the ban holds and the clock runs. The parties are due back before Aquilina for a status update, and a later hearing will decide whether the restrictions harden into a longer-term injunction. If Kalshi does not have Michigan geofenced by the deadline, the fines jump to $500,000 for every day it stays out of compliance.
