The Michigan Gaming Control Board (MGCB) has unveiled that Polymarket will stop offering sports event contract trading across the state by November 25, in exchange for state regulators agreeing to not file enforcement action so long as the operator remains compliant.
Polymarket now joins Robinhood and Coinbase in choosing to pull its sports event contracts out of Michigan, while Attorney General Dana Nessel managed to secure a preliminary injunction order against Kalshi as well.
Nessel spoke on Polymarket choosing to remove its sports event contracts out of Michigan, having 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.”
The prediction market operator will also close out any remaining open customer positions, with the agreement between Polymarket and the MGCB having been approved by the US District Court for the Western District of Michigan.
“Polymarket joining Kalshi, Robinhood and Coinbase in stepping back from these unlicensed sports contracts shows that Michigan’s approach is working,” MGCB Executive Director Henry Williams said.
“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.”
Despite the setback in Michigan, Polymarket recently expanded its presence across the US after forming a new partnership with the National Basketball Association (NBA), alongside Kalshi.
Under the deal, Kalshi and Polymarket gain access to official NBA data and the right to use the league’s marks and logos on their sites.
The NBA said the partnerships create an integrity framework that gives the league greater influence over the markets offered, along with information sharing and a memorandum of understanding with the Commodity Futures Trading Commission.
Polymarket appointed former White House employee Ryan Baasch as the operator’s new VP of Legal & Government Affairs on October 8, having previously served under President Donald Trump
