The U.S. Commodity Futures Trading Commission has ended the public comment period on its proposed prediction market event contract rule after receiving more than 1,500 submissions. The responses showed continued disagreement over how these products should be regulated. Polymarket and Kalshi supported a unified federal framework, while some participants and state gambling regulators called for stricter enforcement, including stronger action against insider trading and illegal betting. Earlier feedback also included Coinbase’s call for the CFTC to keep prediction markets under existing derivatives rules rather than creating a separate regime.
