Ninth Circuit: Prediction Markets Not Exempt from State Gambling Laws

The Ninth Circuit Court of Appeals ruled against prediction market platforms Kalshi and Polymarket, stating that federal derivatives oversight does not exempt them from state gambling laws. This decision significantly impacts the operational legality of crypto-centric prediction markets, particularly those offering event-based contracts. It clarifies that states can pursue enforcement actions against these platforms, potentially limiting their offerings or forcing them to exit certain jurisdictions. Investors should monitor how this ruling influences the regulatory landscape for decentralized prediction markets and the broader crypto derivatives space, as it could lead to increased state-level scrutiny and compliance costs.

This ruling highlights the ongoing tension between federal and state regulatory bodies in the digital asset space. It underscores the fragmented legal environment crypto companies operate within, particularly for novel financial products. This jurisdictional uncertainty will likely suppress innovation and institutional adoption in the prediction market sector.

The Ninth Circuit said federal derivatives oversight does not shield prediction market firms from state gaming enforcement.
