Polymarket and Major League Soccer (MLS) announced a multi-year, exclusive partnership that designates the prediction-market platform as the league’s official and exclusive prediction-market partner. The agreement spans MLS regular season matches, the MLS All-Star Game, the MLS Cup presented by Audi, and the Leagues Cup, and it grants Polymarket Authorized Gaming Operator status.
The partnership is designed to integrate real-time prediction markets into live and second-screen fan experiences in order to surface collective sentiment during matches. Certain elements are expected to run through at least the 2028 season, and the rollout is explicitly positioned to put MLS in front of the 2026 FIFA World Cup attention cycle.

Product Integration and Content Rights
The agreement formalizes Polymarket as a licensed content and market partner, including access to proprietary league data and rights to use official MLS branding. This structure turns Polymarket into a sanctioned distribution channel for prediction markets that are built directly on official league content and data.
Polymarket plans to list markets tied to granular in-game events and broader season outcomes, with market pricing intended to reflect aggregated fan forecasts in real time. Examples cited include next goal scorer, penalty outcomes, the number of corner kicks in a half, and season-long outcomes such as the league champion, all framed as a new engagement layer around match viewing.
MLS and Soccer United Marketing described the collaboration as an innovation play that adds a data-driven overlay to broadcast and digital content. By converting fan predictions into a quantifiable signal, the partnership is positioned as a mechanism to deepen engagement rather than a standalone betting product.
Financial terms, including any revenue-sharing model, were not publicly disclosed. The absence of disclosed economics means stakeholders will need to evaluate performance through observable engagement and integrity outcomes rather than contract-level revenue metrics.
Integrity Controls and Regulatory Context
The partnership includes integrity and compliance mechanisms intended to reduce manipulation and align the product with regulated gaming practices. A central control is that players, coaches, staff, owners, and referees are explicitly barred from trading on soccer-related markets.
MLS retains the ability to veto or remove markets it believes are vulnerable to manipulation or could compromise competitive integrity. This league-level control over market design is framed as a governance backstop that prioritizes integrity over product breadth.
The announcement also cited third-party monitoring, with independent firms contracted to monitor trading patterns for suspicious activity and support investigations when needed. External surveillance is positioned as a credibility lever designed to strengthen enforcement beyond internal platform monitoring alone.
On the enforcement side, Polymarket’s U.S. application will apply restricted individuals lists tied to identified users. That restriction layer is presented as a practical mechanism to operationalize eligibility rules and reduce prohibited participation risk.
The use of official MLS data for settlement was highlighted as another safeguard that improves settlement accuracy and transparency. Proprietary feeds are framed as a way to reduce disputes and tighten the audit trail around outcome resolution.
These measures sit against ongoing legal scrutiny for prediction markets across several U.S. states and a fragmented regulatory environment. By operating under the Authorized Gaming Operator framework and layering third-party oversight, the partners are attempting to navigate state-level distinctions between prediction markets and traditional gambling even as the landscape remains unsettled.
Supporters view the deal as a legitimization step for prediction markets in mainstream sports, while critics raise ethical concerns about blending fandom with wagering primitives and the potential for gambling-related harm. MLS’s controls are presented as an attempt to address these concerns through limits on participation, stronger transparency, and tighter monitoring of market design and trading behavior.
Investors, compliance teams, and product leads will be tracking engagement and integrity signals as markets roll into broadcasts and digital experiences. Commercial outcomes will hinge on user activity, monitoring robustness, and how regulators and state authorities interpret the Authorized Gaming Operator model through the 2026 season and into the contract period running through at least 2028.
