Overview
- Major League Baseball named Polymarket its official prediction market partner, a deal the league says will help protect the integrity of the game.
- Prediction markets operate under the federal Commodity Exchange Act with CFTC oversight, which lets them run in all 50 states and accept users as young as 18 in ways state sports-betting rules often do not.
- Critics warn these markets are prone to insider trading, pointing to outsized wins tied to sensitive geopolitical moves, while Polymarket says it polices such abuse.
- Bipartisan lawmakers have introduced bills to bar sports-style contracts on federally regulated prediction platforms, a move that would directly undercut league deals like MLB’s.
- Reports say MLB’s agreement includes an opt-out if courts later block sports contracts and could pay the league up to $300 million over three years, reflecting both the legal risk and the financial lure.
