Michigan joins states warning sportsbooks against prediction markets

Summary

The Michigan Gaming Control Board (MGCB) has sent a memo to licensed sportsbooks warning that offering sports event contracts — commonly called prediction markets — could put their licence at risk. The move follows similar actions by other state regulators, including cease-and-desist letters and lawsuits from Ohio, Arizona and the Massachusetts Attorney General.

Despite federal oversight of event trading platforms by the Commodity Futures Trading Commission (CFTC), states are pursuing enforcement and litigation to argue prediction markets may amount to illegal sports betting. Key industry players such as FanDuel (via a tie-up with CME Group), Underdog and DraftKings have signalled or begun moves into prediction products, while platforms like Kalshi and Robinhood are expanding offerings. The MGCB also reminded licensees they must notify the agency before offering sports event contracts as it evaluates ongoing suitability for licensure.

Key Points

The MGCB warned sportsbooks that involvement in sporting event contracts could jeopardise their Michigan licence.
State regulators (Ohio, Arizona) and attorneys general (Massachusetts) have issued warnings, cease-and-desist letters or lawsuits against prediction-market operators.
The CFTC regulates event trading at the federal level, but legal disputes continue over whether prediction markets constitute state-regulated sports betting.
Major operators and platforms (FanDuel, DraftKings, Underdog, Kalshi, Robinhood) are expanding into event-based prediction products, raising compliance questions.
Regulatory scrutiny is escalating nationwide, increasing legal and operational risk for operators that move quickly into these products without regulatory clearance.

Why should I read this

Short and blunt: if you work in sports betting, compliance or product at an operator or platform — don’t sleep on this. States are lining up, lawsuits are live and regulators are signalling enforcement. Jump into prediction markets without thinking it through and you could be looking at serious trouble for your licence. This tells you where the immediate risk is and who’s already getting dragged into court.

Author note (punchy)

This matters now. Regulators are tightening the screws while big firms test the waters — the next few months will shape whether prediction markets become a mainstream regulated product or a litigation hotspot.

Context and Relevance

The story highlights a growing regulatory clash: federal oversight (CFTC) versus state-level gambling laws. For anyone building products, drafting compliance policies or advising on US market entry, this is a live regulatory trend that affects product design, licensing strategy and legal risk. It also signals that even well-capitalised operators may face sudden enforcement actions or requirements to adjust offerings depending on state responses.
