The biggest match of the 2026 FIFA World Cup so far isn’t just a football story. It’s a crypto prediction market story. France and Spain meet in the semifinal on July 14 at AT&T Stadium in Arlington, Texas, and the real scoreboard worth watching might be the one tracking billions in prediction market volume.
Polymarket, the Polygon-based prediction platform that became a household name during the 2024 US election cycle, has France trading at roughly 60 cents, implying a 60% probability to advance past Spain. Spain sits at 41 cents. For those keeping track, yes, that adds up to more than 100%, which is how prediction markets bake in their margin.
The numbers behind the noise
Polymarket alone has seen approximately $2 billion in trading volume on the overall World Cup winner market. Combine that with activity on other major prediction platforms, and the total approaches $3 billion. That figure had already been building by mid-June 2026, weeks before the tournament’s later stages even kicked off.
To put that in perspective, Polymarket’s total volume across all markets during the entire 2024 US presidential election was widely reported in the single-digit billions. A single sporting event is now generating comparable interest.
