Polymarket has signed a multi-year deal with Major League Soccer to become the exclusive prediction market partner for the league and its flagship tournament, the Leagues Cup.
The partnership will see Polymarket and MLS develop new fan engagement tools, including second-screen experiences that integrate real-time data, statistics and predictive markets around matches and season narratives.
“As soccer’s audience continues to grow and evolve in the US, fans are looking for new ways to engage more deeply with the game,”
Said Polymarket founder and chief executive Shayne Coplan.
The companies said the deal comes as soccer interest builds ahead of the FIFA World Cup being hosted in North America later this year, underscoring sustained momentum for the sport.
MLS and Polymarket said the agreement includes safeguards to protect match integrity, such as independent monitoring of trading activity linked to MLS and Leagues Cup events.
The announcement comes as prediction market volumes continue to hit records, with platforms such as Kalshi and Polymarket benefiting from clearer regulatory signals from the Commodity Futures Trading Commission.
However, prediction markets face ongoing legal challenges, as several US states argue sports-related contracts amount to unlicensed betting, a claim the platforms dispute by asserting exclusive CFTC oversight.
