Is Polymarket US legal in Michigan?
Yes, today. Polymarket US is available in Michigan, but Michigan has acted over its sports event contracts: a court case over them is ongoing. Polymarket US told us in writing on October 23, 2026 that it is available in every state except Nevada. No order currently blocks access in Michigan; that could change. This page reports what Polymarket US and the state have done; it is not a legal conclusion, and courts are still deciding how state law applies to event contracts.
