Michigan Scores Major Victory Against Prediction Platforms

Michigan Attorney General Dana Nessel has secured a preliminary injunction against prediction platform Kalshi, forcing the company to stop offering sports-related prediction contracts in the state. The ruling adds fresh fuel to the ongoing clash between prediction markets and state regulators, as the legal status of sports prediction contracts continues to be hotly debated.

Kalshi Must Stop Offering Sports Contracts in Michigan

The court order blocks Kalshi from offering what Nessel has described as illegal online sports betting. Under the injunction, the platform must use geofencing technology to prevent anyone in Michigan from accessing the disputed contracts. If Kalshi violates the order, it could face fines of up to $500,000 per day.

Nessel welcomed the decision, saying Kalshi had tried to bypass Michigan’s gaming regulations.

“Kalshi long attempted to pass itself off as a legitimate gaming operation in our state, and I am relieved that this order further protects Michigan residents from its predatory, unlicensed practices.” — Dana Nessel, Michigan Attorney General

Michigan has regulated online sports wagering since 2021, and operators must be approved by the Michigan Gaming Control Board before offering such services. The state’s case against Kalshi hinges on the platform’s lack of a state license.

Why Michigan Calls It Illegal Betting

Nessel argues that Kalshi’s sports prediction contracts are essentially a form of wagering, even though the platform presents them as financial instruments. According to the lawsuit, customers place money on the outcome of sports events and receive payouts if their prediction proves correct. Michigan contends that this is indistinguishable from sports betting.

Kalshi disagrees, maintaining that its products are regulated at the federal level and therefore fall outside state authority. That argument has not prevented legal action in multiple states, making the Michigan case just one piece of a much larger national dispute.

This injunction is the latest development in an ongoing legal fight. In June, Nessel secured a temporary restraining order that stopped Kalshi from operating or marketing its sports contracts in Michigan. The company later tried to move the case from state court to the U.S. District Court for the Western District of Michigan, but Nessel objected, and the lawsuit stayed in Ingham County Circuit Court.

The outcome could have implications far beyond Michigan. Prediction market operators want to expand into every U.S. state and broaden their product offerings, pushing the boundaries between financial markets and state-controlled gambling. State authorities, however, have little reason to welcome companies that offer sports contracts without the licensing, taxation, and consumer protections required of sportsbooks.

What’s Next for Prediction Markets?

Despite Michigan’s legal victory, the future of prediction markets in the state remains uncertain. Courts in different jurisdictions have issued conflicting rulings, and the question of who has the authority to regulate sports prediction contracts is still unresolved.

New Jersey has asked the U.S. Supreme Court to step in and deliver a definitive answer. While there is no guarantee the Supreme Court will rule in favor of the states, a final decision would at least remove the uncertainty that currently surrounds prediction platforms.
