Coinbase Loses Michigan Prediction Markets Legal Battle

Coinbase suffered a setback in court on Thursday when a federal judge ruled that Michigan can enforce its sports betting laws against event contracts offered on the exchange. Judge Shalina D. Kumar dismissed the central legal argument from Coinbase, calling the claims applesauce in a strongly worded 47 page opinion. The exchange had sued Michigan, Illinois, and Connecticut in December, arguing that federal commodities law gave regulators exclusive jurisdiction over these markets and blocked state action.

Judge Kumar rejected the theory that sports event contracts qualify as swaps under federal law, putting her decision at odds with a recent ruling from the Third Circuit. She noted that complying with state rules alongside federal oversight might be expensive and challenging, but that high costs do not make compliance impossible. The court did dismiss the state gaming control board itself due to immunity, but the lawsuit remains active against the board directors and the state attorney general.

This ruling deals a blow to the expansion of crypto prediction markets as exchanges push to offer event contracts nationwide. Coinbase faces similar ongoing legal battles in Illinois and Connecticut, while facing a separate state court suit in Nevada. Traders and market watchers should keep an eye on how these remaining state cases unfold, because conflicting federal and state court decisions will likely force a final showdown in higher courts.
