MLS Makes Polymarket Its Exclusive Prediction Market Partner

Even if you don’t actively use prediction markets, it’s hard to escape them right now. They keep popping up in headlines and across social media.

Polymarket has been especially visible, from gifting UFC fighter Paddy Pimblett a reported $500,000 chain ahead of his fight with Justin Gaethje, to making a similar splash with Anthony Joshua before his exhibition, I mean “professional” bout with Jake Paul.

At the same time, Polymarket has also drawn the attention of regulators. Portuguese authorities ordered the platform to stop offering services to their residents, pointing to the lack of a national gambling licence and the fact that betting on political events is prohibited under Portuguese law.

All of that context makes the timing of Major League Soccer’s latest move especially interesting.

MLS Confirms Polymarket as Its Exclusive Prediction Market Partner

Major League Soccer has named Polymarket its exclusive prediction market partner through a multi-year deal announced via Soccer United Marketing.

The partnership covers MLS competitions and marquee events, including the regular season, MLS Cup, the MLS All-Star Game, and Leagues Cup.

In practical terms, “exclusive” means Polymarket is the only prediction market allowed to use official MLS branding, marks, and data within that category.

It also signals that MLS is not treating prediction markets as a fringe experiment, but as something it wants formally integrated and controlled.

From a fan perspective, this isn’t about encouraging everyone to start trading markets. MLS has framed the partnership around engagement and insight rather than betting.

We’re likely to see Polymarket probabilities and market sentiment used as a way of showing how expectations shift before and during matches, much like live win-probability graphics used by broadcasters.

For fans who don’t touch prediction markets at all, this still matters. These probability-based insights are increasingly being used as content, not just wagering tools, and MLS clearly wants to be part of that trend rather than watching it happen elsewhere.

Integrity, Data, and Market Limits

This is arguably the most important part of the entire deal. MLS is not giving Polymarket free rein. Instead, the league has made it clear that only official MLS data can be used, alongside independent third-party integrity monitoring, as detailed in the official MLS–Polymarket partnership announcement.

The reasoning is straightforward. Certain markets are far more vulnerable to manipulation or insider knowledge than others.

Outcomes such as yellow cards, disciplinary actions, or similar in-game incidents are exactly the types of markets leagues want to avoid.

By placing clear limits on what can and cannot be offered, MLS is drawing a line between acceptable fan engagement and outcomes that could compromise match integrity.

Rather than allowing prediction markets to operate in a regulatory grey area around its product, MLS is signalling that if these markets exist, they must operate within strict guardrails, with transparency, oversight, and data control at the centre of the partnership.

MLSsoccer wrote: “The partnership includes safeguards designed to protect the integrity of MLS and Leagues Cup matches, including independent monitoring of trading activities and collaboration on MLS and Leagues Cup markets offered.”

Regulation and the Wider Backdrop

The Polymarket partnership doesn’t exist in a vacuum. Regulatory scrutiny surrounding prediction markets is ongoing, particularly when markets start to resemble traditional sports betting or political wagering. The situation in Portugal is a reminder that availability can change quickly depending on local law.

That uncertainty makes MLS’s approach notable. Rather than avoiding prediction markets altogether, the league appears to be leaning into a regulated, authorised-partner model, setting standards instead of ignoring the space.

Final Thoughts

From where we’re sitting, this feels less like a gamble and more like a calculated move by MLS. Prediction markets aren’t going away, and Polymarket is the most visible name in the business, for better or worse.

By making the relationship official, MLS gets data control, integrity protections, and a say in how these markets are presented to fans.

Whether other leagues follow the same path is the real question. If this partnership works without controversy, it’s easy to imagine prediction markets becoming a standard — and carefully managed — part of the modern sports ecosystem.
