Michigan sports betting at a glance

Sports betting law in Michigan

Governor Gretchen Whitmer signed the Lawful Sports Betting Act and the Lawful Internet Gaming Act in December 2019. Retail sportsbooks opened at the three Detroit casinos in March 2020, and online sports betting, casino and poker all went live on January 22, 2021.

Each Detroit casino and each federally recognized tribe can run one online platform, and the Michigan Gaming Control Board authorizes them. Operators pay 8.4% of sports betting revenue in tax, and a proposed per-bet fee was left out of the July 2026 budget. Hard Rock Bet joined in December 2025 and bet365 in April 2026, bringing the count to 13 sportsbooks. In 2026 the state also went after prediction markets, winning an injunction against Kalshi and agreements that ended sports contracts from Robinhood, Coinbase and Polymarket US.
