Michigan Judge Denies Polymarket and Robinhood Injunctions, Says Sports-Event Contracts Likely Are Not Swaps

A federal judge in Michigan has denied preliminary injunction requests filed by Polymarket and Robinhood, concluding that sports-event contracts are unlikely to qualify as regulated swaps under federal law. The ruling also found insufficient evidence that Congress intended to preempt state gambling laws through federal derivatives regulation.

The case centers on the classification of prediction market contracts and whether they fall under Commodity Futures Trading Commission (CFTC) jurisdiction as swaps. The judge's reasoning suggests that sports-event prediction contracts may operate outside federal derivatives frameworks, potentially leaving them subject to state gambling law rather than federal financial regulation. This distinction carries significant implications for the legal status and operational requirements of prediction market platforms.

The decision represents a setback for platforms seeking federal regulatory clarity and protection from state gambling enforcement. However, it does not resolve the underlying legal questions definitively, as further appeals and litigation remain possible. The ruling highlights ongoing uncertainty around prediction markets' regulatory classification and the tension between federal financial regulation and state gambling law—a dynamic that will likely shape the industry's legal landscape for years to come.
