A Michigan judge rejected Coinbase's request to block the state government from enforcing contracts related to sporting events

A federal judge in Michigan rejected Coinbase's request for a preliminary injunction to block state enforcement of sports event contracts. U.S. District Judge Shalina Kumar of the Eastern District of Michigan ruled on Thursday that Coinbase failed to demonstrate that its claims were likely to succeed on the merits of the case, namely that federal law takes precedence over Michigan's jurisdiction.

The cryptocurrency exchange sued the state of Michigan in December 2025, claiming that prediction markets fall under the exclusive jurisdiction of the Commodity Futures Trading Commission (CFTC) under the Commodity Exchange Act (CEA), rather than state regulatory agencies.

Coinbase specifically sought to provide access to event contracts issued by Kalshi for customers on its platform, including those in Michigan. According to the complaint, the exchange claimed that Michigan's laws constitute a "conflict of priority," as these laws undermine Congress's efforts to establish a unified federal regulatory framework.
