Sen. Blackburn leads Senate hearing on sports betting and prediction market rules
Sen. Marsha Blackburn (R-Tenn.) chaired a Senate Committee hearing Wednesday on sports betting and prediction market regulations, raising concerns about allegations of insider trading within prediction markets. Blackburn referenced Tennessee and Saturdays at Neyland Stadium as context for local sports betting activity. The hearing occurred as lawmakers continue examining federal oversight of prediction markets and sports wagering. No witness testimony details, specific legislative proposals, or committee votes were reported from the session. The event marks ongoing congressional scrutiny of the sector as multiple committees pursue parallel inquiries.
Kalshi and Polymarket must now monitor five parallel congressional threats rather than a single committee track. Any insider-trading or KYC mandate that survives markup becomes an immediate compliance burden across both platforms.
Joins four other Senate Commerce hearings this week targeting prediction market advertising, KYC, and sports event contracts as Congress builds multi-track pressure on Kalshi, Polymarket, and Crypto.com ahead of possible markup.
