MLB Taps Polymarket as Official Prediction Markets Partner

MLB just handed Polymarket the keys to its data vault. The league has named the event-prediction platform its official prediction markets partner, complete with exclusive data access through a new licensing agreement.

The deal comes as MLB approaches opening day — and tries to shake off the shadow of a recent betting scandal. Polymarket, for its part, will restrict contracts that could pose an "integrity risk" to the sport.

It's a fascinating move. A major sports league is embracing prediction markets rather than fighting them, but with guardrails. Polymarket gets legitimacy and proprietary data. MLB gets a controlled environment for fan engagement around game outcomes.

The partnership signals that prediction markets are moving from crypto-native curiosity to mainstream sports infrastructure. Whether the integrity safeguards hold up under pressure remains the real bet.
