Coinbase v. Michigan

For the states PI denied; appeal stayed; Coinbase agreed to halt Michigan sports contracts

Judge Shalina Kumar denied Coinbase a preliminary injunction on Aug. 7, 2026, finding sports-event contracts are not necessarily swaps and that complying with both federal law and Michigan's Lawful Sports Betting Act is feasible, calling Coinbase's impossibility arguments 'applesauce.' Coinbase filed parallel suits against Illinois and Connecticut in December 2025; a Sixth Circuit appeal has been reported (number not verified). Per the Michigan Gaming Control Board, Coinbase's Sixth Circuit appeal is stayed pending related appeals involving Robinhood, Polymarket and Kalshi. On Oct. 7, 2026 the state announced a stipulation under which Coinbase will stop offering new sports-related event contracts to Michigan customers (including those traded on Kalshi and other DCMs) and close open positions by 12:00 a.m. ET Oct. 10, 2026; Michigan will not take enforcement action while Coinbase complies and the appeals proceed. The stipulation preserves all parties' rights pending a final Sixth Circuit or Supreme Court ruling.
