Major League Baseball (MLB), one of the “Big 4” U.S. sports leagues, has made Polymarket its official exclusive prediction market partner in a multi-year agreement. The deal gives Polymarket exclusive rights to MLB branding and official data for its U.S. platform.
Exclusive Partnership Grants Branding and Data Access
While MLB did not officially disclose financial details, sources familiar with the matter estimate the agreement is worth roughly $300 million over three years.

Polymarket will gain access to official MLB data via league partner Sportradar. The platform will be able to integrate team and player information into its prediction markets, allowing users to place bets on game outcomes, series winners, and other league events.
The partnership also includes marketing rights, giving Polymarket visibility across MLB digital channels and fan-facing content. The deal could significantly expand the platform’s user base, particularly among sports fans who may not have previously engaged with cryptocurrency products.
MLB and CFTC Sign First-of-Its-Kind Memorandum
As part of the agreement, MLB Commissioner Rob Manfred signed a memorandum of understanding with the Commodity Futures Trading Commission (CFTC). The memorandum establishes a framework for information-sharing to maintain the integrity of the league and its events.
Polymarket will implement integrity controls to restrict high-risk markets, including bets on individual pitches, managerial decisions, or umpire performance. The platform is required to adhere to U.S. regulatory rules, ensuring consumer protections and compliance with federal law.
Implications for Crypto and Sports Markets
The MLB deal represents one of the largest partnerships between a professional sports league and a blockchain-based prediction market.
It follows similar agreements in the NHL, Major League Soccer (MLS), and UFC, signaling a growing trend of sports organizations integrating tokenized and crypto-driven products into fan engagement strategies.
The upcoming MLB regular season, combined with the high-stakes World Series and a growing range of player prop markets, is expected to drive billions of dollars in projected trading volume on Polymarket.
Despite the major MLB-Polymarket partnership announcement on March 19, the market has reacted calmly so far. Trading volumes on the Polymarket remain steady without any dramatic spike in the hours after the news.
Why This Matters
The Major League Baseball and Polymarket partnership marks a major step in mainstream adoption of crypto-based prediction markets, giving it exposure to millions of sports fans. It also signals regulatory acceptance, as MLB and the CFTC establish oversight frameworks.
