Major League Baseball has entered into a partnership with Polymarket, designating the blockchain-based prediction platform as its Official Prediction Market. The news broke on Thursday in conjunction with a companion agreement involving the CFTC.
According to industry sources quoted by Front Office Sports, the partnership carries a valuation ranging from $150 million to $300 million across a potential three-year term.
Under the terms of the agreement, Polymarket and its affiliated brokers will gain exclusive rights to utilize MLB trademarks and logos. Additionally, the Polymarket brand will receive prominent placement across MLB’s digital platforms and at official league events.
The partnership provides Polymarket with access to official league data through Sportradar. This arrangement mirrors the framework typically seen in conventional league sponsorship agreements.
MLB maintains current partnerships with FanDuel, DraftKings, and BetMGM. The Polymarket agreement expands the league’s expanding collection of betting-related partnerships by introducing a prediction market component.
CFTC and MLB Establish Integrity Framework for Baseball
As part of the announcement, MLB Commissioner Rob Manfred and CFTC Chair Michael Selig formalized a memorandum of understanding. The agreement centers on maintaining the integrity of professional baseball within prediction market environments.
“We’ve committed to work together to protect the integrity and resilience of prediction markets relating to professional baseball,” Selig said in a statement.
Manfred characterized the agreements as “imperative steps in proactively managing the new and rapidly growing prediction market space.” He emphasized that safeguarding the game’s on-field integrity continues to be the league’s paramount concern.
The partnership didn’t come as a complete surprise. Manfred hinted at this development in February when speaking to reporters. He revealed that prediction markets were discussed during owners meetings, particularly in connection with a betting scandal involving Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz.
Manfred clarified that the league wanted ownership to grasp the distinctions between prediction markets and conventional sports wagering. He indicated that the league recognized opportunities in collaborating with prediction markets to enhance its integrity safeguards.
Major Sports Organizations Embrace Prediction Market Platforms
MLB now stands as the largest American sports organization to form an alliance with a prediction market. However, it wasn’t the pioneer in this space.
The NHL established licensing partnerships with both Polymarket and Kalshi in October. Polymarket has also secured marketing arrangements with MLS and UFC.
Although Polymarket’s US platform hasn’t completely rolled out, sports event contracts are currently accessible on the application. The MLB logo appears on the platform, though baseball-specific markets haven’t been activated at this time.
The NFL and NBA represent the two remaining major American leagues without prediction market alliances. At February’s All-Star festivities, NBA Commissioner Adam Silver indicated that the league approaches prediction markets with the same scrutiny it applies to sports betting operators.
The NFL subsequently moderated previous statements from Executive VP Jeff Miller regarding the fan engagement advantages of prediction markets.
Prediction markets function on blockchain infrastructure and enable users to trade shares based on real-world event outcomes. They’ve attracted significant interest from cryptocurrency enthusiasts and traditional financial sectors alike.
The CFTC maintains regulatory authority over these markets at the federal level. The agency’s participation in the MLB partnership demonstrates an ongoing commitment to supervising prediction market activities connected to professional sports.
MLB’s Polymarket partnership, reported at $150-300 million across three years, represents one of the most substantial prediction market sponsorship arrangements in professional sports history.
