Major League Baseball has announced that it has named Polymarket its official prediction market exchange and signed a memorandum of understanding with federal regulators. The partnership includes exclusive rights to use team logos and marks as part of a partnership that also includes an agreement with the Commodity Futures Trading Commission (CFTC). The social media backlash was swift and negative, with some users calling the partnership "dislatised" and "dissatisfied". The agreement includes a comprehensive integrity framework to restrict markets that present integrity risks. While Polymarket holds exclusive rights as MLB's official predictions market exchange, the league intends to establish integrity relationships with all other prediction market exchanges offering baseball contracts.
