Detroit city and Michigan state officials initiated legal action against Coinbase on June 22, 2023, accusing the cryptocurrency platform of running an illegal prediction market within the state. The lawsuit contends that Coinbase’s recently launched prediction market platform constitutes unauthorized betting and lottery activity under Michigan law. Officials are seeking a court injunction to prohibit Coinbase from offering or promoting its prediction market services to Michigan residents. Coinbase had publicly rolled out its prediction market feature earlier in June 2023, enabling users to speculate on political outcomes and economic indicators. The legal challenge highlights ongoing regulatory scrutiny around crypto-based betting and gaming products in the United States, with state authorities asserting that such platforms must comply with local gambling laws. This case could set important precedents regarding how prediction markets operated by crypto exchanges are treated under state regulatory frameworks.
