The 2026 FIFA World Cup has closed the books as the largest sports betting event in US history, according to figures now emerging from the best sports betting sites and prediction market apps across the country. The tournament wrapped up over the weekend with Spain topping Argentina 1-0 in the final held in New Jersey, capping a 104-match run that marked the first time the World Cup expanded to a 48-team field.

Neil Walsh, Senior Vice President at Hard Rock Bet, described the scale of the action in blunt terms, saying the tournament amounted to roughly ten Super Bowls' worth of betting activity and noting that a sport once considered a tough sell to American audiences had become a defining moment for the industry.

Exact figures vary by source since not every operator has disclosed its totals, but analysts at the Action Network estimate that legal US sportsbooks processed between $2.8 billion and $4.3 billion in wagers over the roughly five and a half weeks of competition. That dwarfs the estimated $1.7 billion wagered through licensed books during this year's Super Bowl matchup between Seattle and New England.

Prediction markets provided some of the clearest numbers. Kalshi alone processed $12 billion in tournament-related bets, with more than $1.5 billion of that riding on the outright champion, compared with roughly $900 million wagered on that same market during the Super Bowl.

The World Cup outright winner contract became Kalshi's largest single market to date, edging out betting tied to the 2024 presidential race.

Prediction markets cemented their place

That surge in outright market volume reflects a broader shift in the industry, with prediction platforms accounting for about 27% of all legal sports betting activity tied to the World Cup, up sharply from roughly 9% at the start of the year. The estimate comes from H2 Gambling Capital and covers public wagering data collected during the tournament's opening month.

Kalshi, the largest platform in the space, broke its own internal trading records several times throughout the event, at one point trading at nearly ten times the pace it saw earlier in 2026. App tracking firm Apptopia found that Kalshi pulled in more daily users during the tournament than either DraftKings or FanDuel, the two biggest traditional sportsbook apps in the country. Kalshi also clocked three million new users during the tournament.

An analyst at Bernstein said the growth puts pressure on legacy sportsbooks to build out similar offerings of their own. The tournament gave both Kalshi and Polymarket a high-profile stage to demonstrate how far that landscape has shifted, with federal oversight from the Commodity Futures Trading Commission allowing them to roll out new betting products while fending off legal challenges from state regulators.
