The U.S. Commodity Futures Trading Commission (CFTC) signs a memorandum of understanding (MOU) with the National Hockey League (NHL) as prediction markets linked to sports continue to grow in popularity. The Block reports that the agreement reflects the spread of sports-based prediction markets into mainstream use. Cointelegraph adds that the CFTC has recently worked on similar arrangements, including an MOU with Major League Baseball (MLB) in March. Beyond cooperation with major leagues, both outlets indicate the CFTC also remains focused on enforcement and regulatory actions. Cointelegraph notes that the agency continues to file lawsuits involving state authorities that have targeted prediction market platforms connected to sports betting. Taken together, the reporting describes a parallel track: the CFTC is both establishing frameworks for engagement with major sports organizations through MOUs and pursuing legal action where it believes platforms operate outside applicable regulatory boundaries. The NHL MOU is presented as another step in this broader effort to address and manage the rapid expansion of sports-related prediction markets.
