Michigan Judge Blocks Kalshi Sports Event Contracts

Key Highlights

A Michigan judge’s ruling has initiated another setback for prediction market platforms, further muddying the waters on their legality at the state level.

Michigan Court Halts Kalshi Sports Bets

On June 29th, Ingham County Circuit Court Judge Rosemarie Aquilina blocked Kalshi from allowing residents to trade on event contracts related to sporting outcomes in Michigan. The decision aligns with the argument held by many prominent state officials, who claim that Kalshi’s sports markets function like online sports betting, even though the company describes them as financial event contracts.

The ruling also carries a major financial warning. Kalshi could face a $120,000 fine for each day the site offers online betting in Michigan, adding immediate pressure for the company to comply with the court’s order.

Kalshi lets users buy and sell contracts based on whether real-world events will happen. In sports, those contracts can be tied to outcomes similar to what consumers would find on a sportsbook, including game results or other sports-related events. It is regulated by the federal Commodity Futures Trading Commission, but Michigan officials contend the platform must follow the state’s sports betting rules and obtain approval from the Michigan Gaming Control Board.

State Officials Challenge Event Contract Model

Building on the argument held by several other states, Michigan’s claim is that Kalshi is effectively providing unlicensed internet sports betting to residents. The case centers on whether Kalshi’s products should be treated as regulated financial contracts or sports wagers subject to state gaming law.

Michigan’s biggest concern is that Kalshi’s platform gives users a way to wager on sports while avoiding requirements imposed on licensed sportsbook operators. Those rules are intended to oversee online sports betting, protect consumers, and keep gambling activity within Michigan’s legal framework.

Kalshi has pushed back against similar claims in other jurisdictions by arguing that its contracts are regulated financial products, not state-regulated sports wagers.

Ruling Adds Pressure Across States

The Michigan ruling adds to the regulatory pressure facing Kalshi and other prediction market operators as they expand into sports-related contracts. State officials across the country have pushed back on the notion that these products are regulated financial contracts, especially when they involve teams, game results, or player-related outcomes. In May, Minnesota became the first state to ban prediction markets, which drew quick reaction from the CFTC in the form of a federal lawsuit. 

Kentucky also recently sued Kalshi and Polymarket, citing concerns similar to those in Michigan and Minnesota, among other states.

For the time being, Kalshi cannot continue to offer sports-related markets in Michigan under the model being challenged. The case also gives state regulators another court decision to cite as they argue that sports event contracts should fall under their gambling oversight.
