Traders on Polymarket have poured more than $2.6 billion into a single market betting on which nation lifts the 2026 World Cup trophy, the platform's largest sports wager ever.
Key Points:
- Polymarket's World Cup Winner market has drawn over $2.6 billion in trades during the group stage.
- France leads the field near 18 percent, while Spain sits second after a flat draw with Cape Verde.
- Combined with Kalshi, prediction-market volume on the tournament neared $4.8 billion within two days of kickoff.
Polymarket Volume Tops $2.6B
The milestone surfaced Thursday, when tallies reported across sports media showed the World Cup Winner contract clearing $2.6 billion midway through the group stage. The contract has run since July 2025. It now towers over anything the platform has hosted outside a national election.
France leads the field near 18 percent, the equivalent of about 18.5 cents per share. The 2018 champion opened with a 3-1 win over Senegal and meets Iraq next week, leaving it a clear path to the round of 32.
Spain tells a different story.
The Euro 2024 winner sits second around 14 percent after a flat 0-0 draw with Cape Verde, a result that cooled the favorites and handed bargain hunters a cheaper entry, with live prices still posted on the platform's market page. Argentina, the defending champion, and England round out the top tier, while Brazil hovers as a long shot near 7 cents.

Prediction Markets Rival Sportsbooks
Brokerage Bernstein tracked combined World Cup volume on Polymarket and Kalshi rising from $2.2 billion on Jun. 11 to $4.8 billion a day later. The pace cleared Super Bowl prediction-market activity within 48 hours.
Kalshi alone logged a record week near $7 billion across all its markets, a rise of roughly 13 percent that the tournament largely drove. The two venues now anchor a betting boom fed by an expanded 48-team field, a slate of 104 matches and kickoffs that fall during peak US viewing hours.
Regulated sportsbooks across the country could handle as much as $4.3 billion before the final.
The climb has been steady through the group stage. Individual nation contracts have each drawn tens of millions, and one trader staked more than $3 million on the Netherlands to beat Japan, a wager that pushed that match past $26 million on its own.
Daily volume around marquee fixtures has at times cleared $100 million, a scale that frames the World Cup as Polymarket's biggest event short of a presidential race.
