Michigan's iGaming market has grown to become the second-largest in the U.S. with 15 licensed commercial and tribal online casino operators. Michigan joined the Multi-State Internet Gaming Agreement (MSIGA) in 2022, enabling shared player liquidity for online poker with New Jersey, Delaware, and Nevada. West Virginia subsequently joined the agreement, and Pennsylvania joined the MSIGA on April 27, 2025, expanding the shared pool to six states: Michigan, New Jersey, Delaware, Nevada, West Virginia, and Pennsylvania. In November 2024, the MGCB authorized BetMGM to enable shared liquidity for multi-state internet poker games.
