MLB Selects Polymarket as Exclusive Prediction Market Partner

💬 The US Major League Baseball, with 30 clubs and $11 billion in annual revenue, has chosen a decentralized crypto platform as its official betting partner. This is not advertising – this is integration.

The US Major League Baseball (MLB) announced a partnership with Polymarket, the largest decentralized prediction platform on the blockchain. Under the terms of the agreement, Polymarket becomes the exclusive official partner of MLB in the “prediction markets” category.Fans will have access to official betting markets – from individual match outcomes to the championship – directly through the league’s app and website.Integration will start with the opening of the 2026 season.This is the largest sports license in the history of the blockchain industry – and the first such agreement with a league at the level of MLB, NFL, NBA or NHL.

What is Polymarket and why MLB chose it

Polymarket is a decentralized platform based on Polygon, where users bet real money (in USDC) on the outcome of events: elections, sports, crypto, geopolitics.In 2025-2026, the platform gained mass popularity due to its accuracy in predicting the US presidential elections – its forecasts were ahead of traditional polls. Monthly trading volume reached $564 million in March 2026. Unlike traditional bookmakers, Polymarket operates without a centralized counterparty – users trade directly with each other using the AMM mechanism.MLB was attracted to this transparency. Traditional bookmakers in the US operate in a regulatory gray area, with their margins hidden in the odds. Polymarket is a public smart contract: every transaction is visible on the blockchain, market manipulation is technically almost impossible. For a league that actively fights against match-fixing, this is a fundamental argument.

What is changing for the crypto market

MLB has 30 clubs, about 73 million stadium visits per year, and a television audience of hundreds of millions of people. The partnership means millions of fans who have never interacted with crypto before will open a USDC wallet for the first time to participate in official betting on their favorite team.This is one of the largest potential onboarding channels for stablecoins and Web3 applications in the history of the industry.📌 Key facts
