Polymarket US Pulls Sports Event Contracts From Michigan

• Polymarket has pulled its sports event contracts from Michigan
• The Michigan Gaming Control Board and Polymarket negotiated the decision
• All open contracts will be closed by Nov. 25 in the state

Polymarket US has joined Robinhood and Coinbase in its decision to pull its sports event contracts from Michigan.

The Michigan Gaming Control Board today announced the prediction market company’s decision. All sports event contracts will be pulled and any remaining open customer positions will be closed by Wednesday, Nov. 25, 2026.

“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 in a release. “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.”

Similar Deal to Kalshi, Robinhood, and Coinbase

Polymarket’s deal with the Michigan Gaming Control Board is similar to those the board reached with Robinhood and Coinbase. Polymarket will pull its sports event contracts out of the state and close all open positions by Nov. 25, in exchange for the state not taking any enforcement action against the company as long as they remain in compliance of the agreement.

Michigan Circuit Court for the 30th Judicial Circuit of Ingham Country ordered Kalshi to pull its sports event contracts from the state in September.

“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,” said Attorney General Dana Nessel said. “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.”

Polymarket filed a lawsuit against Michigan in federal court in 2026, seeking a preliminary and permanent injunction against the state from enforcing its gambling laws against its sports event contract markets. However, the federal court ruled in favor of the state.

Polymarket filed an appeal of the decision in the Sixth Circuit, which is still pending. Kalshi and Robinhood filed similar appeals as well.

Fourth Operator to Cease Contracts

Polmarket is now the fourth prediction market company to cease offering sports event contracts in Michigan. Earlier this month, Coinbase agreed to cease contracts in a similar deal with the Wolverine State.

It closed out its open contracts on Saturday, Oct. 10. Robinhood, additionally, closed its open positions the day before on Friday, Oct. 9.

Michigan secured a preliminary injunction against Kalshi in early September. Michigan Circuit Court for the 30th Judicial Circuit of Ingham County granted the state a preliminary injunction which requires Kalshi to utilize a third-party geolocation service to block sports event contracts in the state until the court grants the final order on the case.

Any failure to do so will result in a fine of $500,000 per day.
