CFTC Chair Selig talks with all major US sports leagues to block prediction market insider trading
CFTC Chair Michael Selig disclosed that the agency is in talks with all major US professional sports leagues, including the NFL and NBA, to prevent insider trading on prediction markets through data-sharing arrangements. In remarks on Wednesday, May 13, Selig also insisted that sports betting and prediction markets are 'two separate things,' arguing that prediction market prices reflect real-time customer sentiment rather than traditional wagering dynamics. The comments come as the CFTC applies AI-driven surveillance tools to monitor Polymarket and other crypto-native platforms for illegal activity. Selig did not name specific enforcement mechanisms that might emerge from the league coordination, nor did he detail which leagues beyond the NFL and NBA are involved. The disclosure signals the agency is treating sports-linked event contracts as a priority supervisory area while it continues a broader rulemaking review.
Kalshi and Polymarket face a direct collision: Selig's league talks could produce data-sharing rules that restrict or reclassify their sports-linked contracts, while his 'separate things' framing offers no shelter from four leagues already formally opposing those same products.
Brings every major US sports league into the CFTC's oversight orbit alongside ongoing congressional pressure from Schiff and state-level bans in Minnesota, as Selig tries to thread a needle between federal event-contract approvals and league demands for restrictions.
