Under the new agreement, Polymarket and its brokers gain access to official MLB data, logos, and more|@Polymarket|X
Major League Baseball has named Polymarket its exclusive prediction market partner, marking another progress in the rapidly growing event-based trading sector.
Under the new agreement, Polymarket and its brokers gain access to official MLB data and logos, as well as “brand exposure” across league events.
To address regulatory concerns, the MLB also signed a memorandum of understanding with CFTC Chairman Michael Selig to establish a data-sharing framework aimed at protecting the game’s integrity.
MLB’s move follows similar ventures by the NHL and Major League Soccer, signaling a broader trend of professional sports leagues embracing prediction markets.
However, the partnership also comes amid heightened scrutiny regarding sports betting, particularly after several NBA players were arrested on illegal gambling-related cases in 2025.
