The 2026 FIFA World Cup is underway — and alongside it, prediction markets are handling volumes that would have been unthinkable three years ago.
Polymarket alone has recorded over $1.8 billion in World Cup-related trading volume, with more than 4,000 active sports markets on the platform. Kalshi has built out 424 World Cup markets covering everything from group stage outcomes to individual match results.
The 2024 US Presidential Election put prediction markets on the mainstream map — Polymarket processed over $3.7 billion in election-related trades. But elections happen once every four years. Sports happen every week. The World Cup — a tournament with a global audience of 5 billion — is the industry's first true demonstration of what scale looks like for sports markets.
Unlike political or economic prediction markets, sports markets are resolved in hours rather than months. That fast settlement cycle creates tighter bid-ask spreads, higher turnover per dollar of open interest, and a user demographic that includes active sports bettors migrating from traditional sportsbooks.
The CFTC's June 10 proposed rulemaking explicitly permits sports contracts tied to final scores, point differentials, and tournament advancement — precisely the markets generating the most World Cup volume. The regulatory clarity arrives at the right moment.
