Summary
Michigan’s attorney general Dana Nessel announced that a state court issued a preliminary injunction against prediction markets platform Kalshi, blocking it from offering event contracts to Michigan residents. The injunction followed a lawsuit alleging Kalshi violated state sports gambling laws. Kalshi disagrees with the ruling and plans to contest it in court. Meanwhile, New Jersey officials have petitioned the U.S. Supreme Court to weigh in on whether prediction markets fall under federal or state jurisdiction.
Why it matters
This development highlights ongoing legal conflicts over the regulatory authority of prediction markets in the U.S., specifically around whether the Commodity Futures Trading Commission (CFTC) or individual states have jurisdiction. The Supreme Court petition from New Jersey could resolve these competing legal theories, potentially impacting how prediction markets are regulated nationwide. The source does not elaborate further on the broader market or user implications.
Key context
Michigan previously issued a temporary restraining order in June forbidding Kalshi from offering sports betting, which the CFTC opposed, instructing Kalshi to continue operating, thus placing the company in a challenging legal position. Similar lawsuits targeting platforms like Polymarket have occurred across multiple states. U.S. lawmakers have also proposed legislation to prohibit CFTC-registered platforms from listing contracts resembling sports bets, directing regulatory authority to states.
Key numbers and entities
The Michigan court could fine Kalshi up to $500,000 per day for violations. Key entities include Kalshi, Michigan Attorney General Dana Nessel, the 30th Judicial Circuit Court in Ingham County, the CFTC, New Jersey state officials, Senators Adam Schiff and John Curtis, and legal expert Melinda Roth.
What remains unclear
The source does not specify how Kalshi is complying with the injunction or the timeline for anticipated court proceedings. It also does not clarify whether the Supreme Court is likely to accept New Jersey’s petition or what impact Congressional legislation might have on the ongoing cases. The exact nature of the contracts Kalshi offers and their classification remain outlined but not detailed.
