The agreement with Michigan’s gambling regulator stays any enforcement action against the prediction markets platform
Polymarket is withdrawing its sports-related event contracts from Michigan under an agreement with the state’s gambling regulator.
Under the terms of the court-approved agreement with the Michigan Gaming Control Board (MGCB), Polymarket will cease to offer new sports event contracts in Michigan and close out all existing contracts by November 25.
In exchange, the state has agreed not to take enforcement action against the company so long as it remains in compliance.
The gambling regulator said that the agreement with Polymarket, which is similar to recent agreements with Coinbase and Robinhood, continues its action against “sports wagering products disguised as federally regulated prediction markets”.
Michigan also has a preliminary injunction to prevent Kalshi from offering sports event contracts in the state.
“Polymarket joining Kalshi, Robinhood, and Coinbase in stepping back from these unlicensed sports contracts shows that Michigan’s approach is working,” said MGCB executive director Henry Williams. “We expect all operators to respect Michigan’s regulatory framework. If you want to offer sports wagering to Michigan residents, you need a Michigan license.”
Polymarket sued state officials in federal court in March 2026, seeking to block Michigan from enforcing its gambling laws on prediction markets. The court denied Polymarket’s request for a temporary restraining order in March and its motion for a preliminary injunction in June.
Polymarket’s appeal of that ruling is pending before the Sixth Circuit.
Michigan Attorney General Dana Nessel said: “One by one, from Kalshi to Robinhood and Coinbase, and this latest agreement with Polymarket, we’re holding the national sports betting industry accountable to Michigan law. Alongside the MGCB, we’re protecting Michigan residents by ensuring gaming in our state occurs in licensed and regulated ways, and under the protections and safeguards afforded by the law.”
