Coinbase loses Michigan bid over sports prediction markets
Coinbase Financial Markets lost its bid for preliminary relief in Michigan on Aug. 6 after U.S. District Judge Shalina Kumar refused to block state officials from enforcing sports betting laws against the companys event contracts. The order leaves Coinbase without the injunction it sought as its challenge continues. Coinbase sued Michigan Attorney General Dana Nessel, arguing that event contracts offered through federally regulated prediction markets fall under the Commodity Exchange Act and the Commodity Futures Trading Commissions exclusive jurisdiction.

Judge rejects Coinbases preemption case Kumar concluded that Coinbase had not shown a likelihood of success on its federal preemption claims, a requirement for preliminary relief. The judge rejected Coinbases argument that sports event contracts necessarily qualify as swaps under the Commodity Exchange Act and therefore sit beyond Michigans gambling authority. The court also rejected Coinbase‘s claim that compliance with federal derivatives law and Michigan’s Lawful Sports Betting Act would be impossible. Kumar wrote that Coinbases assertions were “applesauce,” adding that higher costs or operational difficulty do not establish legal impossibility. The ruling addresses preliminary relief rather than a final judgment. New: District court judge denies Coinbase motion for a preliminary injunction against Michigan. One of my favorite
