The 2026 FIFA World Cup generated $20 billion in prediction market volume, with more than 400,000 wallets placing on-chain bets on the tournament, according to blockchain analytics firm Chainalysis. The US and China contributed the largest country-level flows, and World Cup markets accounted for roughly 63% of all prediction market activity during the event.
A Global Betting Frenzy
Daily betting volume jumped to around $250 million once the tournament started on June 11. The final match day alone drove over $300 million in wagers. One novelty market — whether Cristiano Ronaldo would cry after his last World Cup campaign — pulled in $49 million. The numbers underscore how quickly decentralized prediction platforms have become a major venue for sports-related speculation.
Winners and Losers
Chainalysis found that 55% of participants ended the tournament in profit. But the gains weren't evenly spread: 79% of those winners were experienced prediction market users. Newcomers largely lost money. The data suggests that while the market is accessible, expertise still matters.
Illicit Activity in the Mix
Not all the money was clean. Chainalysis identified roughly 3,700 wallets — under 1% of bettors — with histories of illicit transactions. The largest single source of those funds was Huobi/HTX, which sent at least $5.4 million into World Cup betting wallets. Scam-linked wallets added another $2 million. The figures highlight the ongoing challenge of policing decentralized platforms.
FIFA's Own Blockchain Play
FIFA itself ran an on-chain experiment on Avalanche, collecting $24 million from NFT collectors between May 2025 and the tournament's end. The organization also earned at least $6 million from secondary sales of its NFTs. The move put FIFA directly in the crypto space, even as it oversaw a tournament that drew billions in prediction market bets.
The data raises questions about how regulators will approach the growing intersection of sports and decentralized prediction markets, especially given the illicit flows identified. No major enforcement actions have been announced yet.
