Coinbase will discontinue sports prediction markets for Michigan users effective 12 a.m. ET on October 10, according to an agreement announced by the Michigan Gaming Control Board on October 7. The platform will stop offering new sports-related event contracts and close out remaining customer positions by that deadline.
Michigan Attorney General Dana Nessel said the action reflects ongoing efforts to bring sports betting into compliance with state law. "Our efforts, alongside the Gaming Control Board, are making a clear impression on the executives of the illegal sports betting industry," Nessel stated. "Whether by agreement or court order, we intend to bring all sports betting into compliance with the law."
Henry Williams, executive director of the Gaming Control Board, noted that operators are "halting these activities because they face significant legal consequences for continuing to offer them in our state."
Coinbase is the third major platform to suspend such offerings in Michigan. Robinhood agreed in September to stop new sports contracts and close positions by October 9. Kalshi operates under a state-court preliminary injunction requiring it to geofence Michigan users, with violations subject to a $500,000 daily fine.
As part of the agreement, Michigan has agreed not to take enforcement action against Coinbase during compliance and while related appeals proceed at the Sixth Circuit Court. A federal judge denied Coinbase a preliminary injunction against Michigan in August, with an appeal currently on hold.
Coinbase faces similar regulatory pressure in other states. Ohio's Casino Control Commission issued a cease-and-desist letter directing Coinbase to confirm within 14 days that it has stopped operating online sports gaming. A Connecticut judge denied Coinbase's injunction bid in August, though a federal judge in Chicago blocked portions of Illinois' gambling law on October 2 in a case led by Coinbase.
