Major League Baseball (MLB) has announced agreements with Polymarket, the official prediction market exchange, and the Commodity Futures Trading Commission, aimed at combating threats to the sport's integrity. The deals include exclusive rights to use MLB marks and logos on Polymarket's platform and official data to help resolve markets. The league also announced an information sharing agreement with the CFTC, which oversees the growing prediction market industry. The partnership aims to establish an integrity framework, including restrictions on markets vulnerable to manipulation. This announcement comes after the attorney general of Arizona filed criminal charges against Kalshi, another leading prediction market, for operating an illegal gambling business.
