Michigan court issues preliminary injunction against Kalshi, $500K daily fine

This formalization of the temporary order signals a hardening regulatory posture toward prediction markets at the state level, even as federal momentum shifts. The substantial daily fine escalates operational risk for platforms relying on broad U.S. access, potentially forcing geo-fencing strategies that could become a template for other states. The key tension to watch is whether this state-level resistance spreads or remains isolated, and how platforms balance compliance costs against market liquidity. This is less about the specific contracts and more about the legal fragmentation that could define the sector's near-term operating environment.
