MLB bets on prediction markets with Polymarket partnership

Major League Baseball is partnering with Polymarket on a multi-year prediction-market venture (reported around $300 million) to offer baseball-related contracts, while working with the CFTC to guard game integrity by restricting high-risk markets and sharing data to detect suspicious activity; the deal underscores a broader regulatory debate over prediction markets and includes plans to pursue integrity partnerships with additional exchanges, with Minor League Baseball excluded from the deal.
