Major League Soccer has signed a multi-year agreement naming Polymarket its official and exclusive prediction market partner in the United States. The deal covers MLS, the MLS All-Star Game, MLS Cup, and the Leagues Cup, which MLS runs with Mexico’s Liga MX.
Soccer United Marketing, MLS’s commercial arm, announced that Polymarket will use official league data to provide real-time market expectations for key matches and moments. MLS leaders say this move places the league among the first global soccer competitions to weave prediction markets into the fan experience.
How Polymarket Prediction Markets Will Work for Fans
Polymarket allows users to trade on the outcomes of yes-or-no events, including sports matches. For MLS, markets may focus on match winners, tournament champions, and season storylines, with second-screen experiences that update as games unfold.
Fans will view real-time market data that shows what everyone expects, such as who will progress in the Leagues Cup or win the MLS Cup. In contrast to just watching a static broadcast, this configuration seeks to transform match viewing into a more dynamic, data-driven experience.
Safeguards and the Regulatory Context
According to MLS and Polymarket, the collaboration includes integrity protections, including impartial oversight of trade activities on the Leagues Cup and MLS markets. Referees, owners, players, and league and club employees will not be permitted to trade on associated markets lower the possibility of insider knowledge.
The deal comes as US prediction markets are expanding due to recent regulatory approvals, even as some states continue to oppose them. Unlike traditional sports betting, prediction markets may operate under other legal frameworks, making them accessible in places where traditional sports betting is prohibited.
MLS presents the Polymarket agreement as part of a broader initiative to innovate ahead of the 2026 FIFA World Cup in North America. Younger, tech-savvy fans who anticipate engaging digital sports experiences are the target audience, according to league executives.
By partnering with a cryptocurrency-based prediction market, MLS also ties up with the expanding convergence of digital assets and popular sports. Through this relationship, the league intends to increase fan engagement throughout the season as they follow more than just the final scores; they monitor changing probabilities.
