The city of Detroit is preparing to join Michigan’s legal dispute with Coinbase over prediction market regulation, signaling a growing conflict between state authorities and digital trading platforms. Lawyers representing Detroit plan to file an amicus brief supporting Michigan officials in their lawsuit against the crypto exchange as the case moves forward in federal court.

A judge in the US District Court for the Eastern District of Michigan approved Detroit’s request to participate, granting the city until April 3 to submit its filing. The case stems from Coinbase’s challenge against Michigan regulators ahead of launching prediction market services on its platform.
Coinbase Challenges State Authority Over Prediction Markets
Coinbase filed lawsuits against Michigan and gaming regulators in Connecticut and Illinois in December, arguing that prediction markets should be regulated at the federal level rather than by individual states. The company maintains that such markets fall under the jurisdiction of the Commodity Futures Trading Commission (CFTC) instead of state gambling authorities.
The legal dispute reflects broader tensions as multiple states pursue enforcement actions against platforms offering event-based contracts.
Legal Uncertainty Could Shape Future Prediction Market Oversight
Legal experts suggest the outcome could influence nationwide regulation of prediction markets. Some believe the issue may ultimately reach the US Supreme Court, referencing the 2018 Murphy v. NCAA decision, which granted states authority to regulate sports gambling.
Meanwhile, Detroit’s casino sector remains economically significant, with local casinos generating over $200 million in revenue during January and February and contributing more than $24 million in taxes to the state.
