The Commodity Futures Trading Commission has moved to intervene in the U.S. District Court for the District of Rhode Island to stop the state from applying gambling laws to CFTC-registered contract markets. The agency framed the filing as a defense of its exclusive jurisdiction over event contracts and prediction markets, arguing that the Commodity Exchange Act preempts state laws that purport to regulate designated contract markets. The filing follows a complaint brought late the previous week by a CFTC-registered designated contract market that said it faced imminent unlawful state enforcement. Rhode Island then filed its own complaint in a parallel state case seeking significant civil penalties and demanding that prediction markets cease operations and disgorge profits. The CFTC described the Rhode Island matter as the latest in a series of state challenges to its jurisdiction, following litigation in Arizona, Connecticut, Illinois, New York, and Minnesota.
