Prediction Markets Set New Records During FIFA World Cup as Sportsbooks Also See Massive Handle

The 2026 FIFA World Cup became a landmark event not only on the pitch but also across betting and prediction markets. While Spain’s 1-0 victory over Argentina in the championship match capped an expanded 48-team tournament, the biggest financial story may have been the unprecedented amount of money wagered through both federally regulated prediction markets and traditional sportsbooks.

According to Yahoo Finance, Kalshi and other prediction market operators processed nearly $40 billion in World Cup-related trading volume during the tournament. The World Cup final alone generated nearly $6 billion in trading activity across Kalshi and Polymarket, according to reports, making it one of the largest event-contract markets ever recorded.

The numbers illustrate just how quickly prediction markets have evolved from niche financial products into a major player in sports forecasting.

Prediction Markets Reach a New Milestone

The World Cup represented a breakthrough moment for event-contract trading platforms. Throughout the month-long tournament, users traded contracts on match winners, tournament champions, Golden Boot races, individual player performances, and other outcomes.

Unlike traditional sportsbooks, prediction markets allow traders to buy and sell positions before an event settles, creating a marketplace that resembles financial exchanges.

Yahoo Finance reported that Kalshi’s World Cup markets accounted for nearly $40 billion in total trading volume, with billions of dollars changing hands during the knockout rounds and championship match. The final itself reportedly attracted almost $6 billion in volume across Kalshi and Polymarket.

The tournament also brought millions of new users to prediction platforms, reinforcing sports as the primary driver of recent growth in the sector.

Sportsbooks Also Report Strong World Cup Betting

Traditional sportsbooks like BetMGM and FanDuel experienced one of their busiest soccer events ever.

Operators across regulated U.S. markets benefited from the expanded tournament schedule, additional knockout-round matches, and growing interest in live betting.

Industry analysts had projected approximately $4 billion in legal sportsbook wagers across the United States before kickoff, with the expanded tournament expected to significantly exceed betting totals from the 2022 World Cup.

The championship match between Spain and Argentina generated the largest single-game betting handle of the tournament for many sportsbooks, with money flowing into:

• Match winner markets
• Moneyline wagering
• Both teams to score
• Total goals
• Player props
• Same-game parlays
• Live in-play betting

Many sportsbooks also reported increased wagering on futures markets throughout the tournament as favorites changed following each knockout round.

Championship Game Drives Record Interest

The Spain-Argentina final became one of the most heavily wagered soccer matches in North American history.

Sportsbooks saw substantial action on Spain’s moneyline after reaching the final with victories over Portugal and France, while Argentina attracted significant public support behind Lionel Messi’s final World Cup appearance.

Prediction markets mirrored that interest, with billions of dollars in contracts trading before kickoff and continuing through live markets during the match.

The combination of legal sportsbooks, prediction markets, and exchange-style trading created an unprecedented betting ecosystem around the championship game.

A Growing Debate Over Regulation

The rapid rise of sports event contracts has also intensified regulatory scrutiny. Congress recently held hearings examining whether sports-related prediction contracts should be regulated like traditional sports betting.

Supporters argue these products function as federally regulated financial markets, while critics contend they closely resemble sportsbook wagering and should remain under state gaming oversight.

That debate is expected to continue as prediction markets expand into additional sporting events following the success of the World Cup.

Betting Takeaway

The FIFA World Cup demonstrated that sports betting continues to evolve beyond traditional sportsbooks. Legal operators produced another strong tournament thanks to futures, live betting, and same-game parlays, while prediction markets established themselves as a major force by generating nearly $40 billion in trading volume.

With the 2026 NFL season approaching and other major global sporting events on the calendar, both sportsbooks and prediction markets appear positioned for continued growth as bettors seek new ways to participate in live sporting events.
