Detroit Lawyers Join Michigan's Legal Push Against Coinbase
Detroit's decision to file an amicus brief, a "friend of the court" filing from a party not directly involved in the case, carries unusual weight. The city is home to all three of Michigan's commercial casinos, giving it a direct financial interest in how the state regulates gambling-adjacent products.
Those three casinos generated over $200 million in revenue during January and February 2026 alone, contributing more than $24 million in state taxes over the same period. If prediction markets expand without state oversight, Detroit stands to lose a share of that revenue to unregulated competitors.

Revenue generated by Detroit's 3 commercial casinos, yielding $24M+ in state taxes — the financial stake behind Detroit's amicus brief supporting Michigan's bid to block Coinbase prediction markets.
Detroit is the first U.S. city to formally enter the growing legal dispute over prediction markets by filing an amicus brief. The move could set a precedent, potentially encouraging other gambling-dependent cities like Las Vegas or Atlantic City to file similar briefs in their respective states.
