MGCB highlights enforcement against unlicensed sports-contract platforms in Michigan
Michigan's Gaming Control Board joined the International Association of Gaming Regulators' illegal-gambling awareness week, running November 9–13, and highlighted state enforcement against unlicensed sports-contract platforms. The board said Polymarket US agreed on October 28, with federal court approval, to stop offering new sports contracts in Michigan and close residents' existing contracts by November 25; the Attorney General's office secured a preliminary injunction against Kalshi in September.
Operators offering sports event contracts in Michigan face restrictions when they lack state authorisation.
