The Commodity Futures Trading Commission has filed an amicus brief in the U.S. Court of Appeals for the Sixth Circuit arguing that prediction markets fall within the CFTC’s exclusive jurisdiction. The filing, in KalshiEx LLC v. Matthew T. Schuler, et al., says the federal regulatory framework established by Congress and implemented by the CFTC preempts state laws as applied to CFTC-regulated markets. The brief is part of the agency’s broader effort to oppose state regulation of prediction markets overseen by the CFTC. It asks the appeals court to reject what the Commission described as an unduly narrow view of its jurisdiction taken by a federal district court in Ohio. The CFTC also noted earlier lawsuits against Arizona, Connecticut, Illinois, New York, and Wisconsin, a preliminary injunction against state regulation of CFTC-regulated prediction markets in Arizona, and earlier amicus briefs filed in the U.S. Court of Appeals for the Ninth Circuit and the Supreme Judicial Court of Massachusetts.
