Polymarket Given Deadline to Exit Michigan
The Michigan Gaming Control Board (MGCB) announced that Polymarket must cease offering sports event contracts in the state by the end of the day on November 25, 2026. The board described the agreement as a pivotal achievement for the regulator, marking the latest step in enforcing state gambling laws against prediction market platforms operating within its jurisdiction.
The MGCB alleged that Polymarket had been operating in violation of Michigan’s gambling laws. During the legal process, Polymarket US attempted to stop the state from applying its gaming laws but failed to argue its case successfully. The platform has now agreed to comply with the outcome of several court decisions. This includes a Sixth Circuit decision that upheld the lower court’s ruling regarding the application of gaming laws in the Great Lakes state.
Legal Precedent from Kalshi Injunction
This development follows a broader regulatory campaign that began with the MGCB securing a preliminary injunction against the platform Kalshi. The court ruling against Kalshi paved the way for the MGCB to push back against other companies operating in the same space. According to the regulator, the legal victory against Kalshi established a framework that allowed the board to pressure other operators to cease operations.
This approach resulted in agreements with major financial technology firms, including Coinbase and Robinhood, which had also been offering sports event contracts in Michigan. The sequential nature of these actions reflects a targeted strategy by the state to address unlicensed prediction market providers.
Sequential Withdrawals by Fintech Firms
Coinbase agreed to stop offering sports event contracts and completed the cessation of those operations on October 10. Similarly, Robinhood acquiesced to stop offering the contracts on September 9, with its trading on sports event contracts officially closing on October 9.
These actions have effectively cleared the market of several major unlicensed prediction market providers in Michigan. The MGCB’s strategy has focused on holding national sports betting entities accountable to state-specific licensing requirements, ensuring that gaming activities align with local legal standards.
State Officials Emphasize Regulatory Control
Dana Nessel, the Michigan Attorney General, emphasized the state’s commitment to protecting residents through licensed and regulated gaming. Nessel stated, “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.”
She added, “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.” These statements underscore the state’s position that only licensed operators should conduct sports-related gambling activities within its borders.
With the November 25 deadline approaching, Polymarket is required to fully withdraw its sports event contract offerings. The MGCB and the Attorney General’s office will monitor compliance with this final agreement to ensure the state’s gambling laws are upheld against all unlicensed operators.
Why It Matters
Michigan residents lose access to Polymarket's sports event contracts, joining similar withdrawals by Coinbase and Robinhood. The MGCB's enforcement strategy signals that unlicensed prediction market platforms cannot operate in the state without a license. This clears the market for licensed operators and establishes a legal precedent for regulating digital betting products in Michigan.
