MLB Taps Polymarket for Exclusive Prediction Markets in Multiyear Pact

Major League Baseball signed a multiyear deal making Polymarket the exclusive MLB prediction-market partner, allowing use of team logos though terms were not disclosed (some reports suggest a sizable, multi‑hundred‑million figure). The agreement follows similar moves by the NHL and MLS and includes coordination with the CFTC to protect game integrity by restricting markets tied to pitches, manager decisions, or umpire calls. Sportradar remains MLB’s data distributor, and Polymarket and Kalshi are drawing significant investment as the broader prediction-market sector grows.
