MLB names Polymarket exclusive prediction‑market partner and strikes CFTC info‑sharing pact to safeguard integrity
Major League Baseball has designated Polymarket as its exclusive prediction market partner and established a first‑of‑its‑kind information‑sharing arrangement with the U.S. derivatives regulator.
Major League Baseball has named Polymarket its exclusive prediction market partner, granting the platform rights to use MLB branding, official statistics and promotional opportunities across league functions [1] [2] [3].
The agreement is paired with a memorandum of understanding between MLB and the U.S. Commodity Futures Trading Commission (CFTC) that creates information‑sharing protocols intended to protect market integrity around betting and prediction markets [4] [3].
MLB said the move comes as the league responds to betting‑related integrity concerns, including recent criminal indictments tied to alleged pitch‑fixing involving Cleveland Guardians pitchers, which have prompted heightened scrutiny of wagering and market activity [3].
League and regulator statements describe the Polymarket partnership and the CFTC MOU as a novel framework to support oversight and data sharing for prediction markets connected to MLB events [1] [4] [3].
