The blockchain analytics firm finally put a number on what football fans already suspected. Crypto turned the 2026 world cup into its biggest live betting event yet.
According to the analytics firm the World Cup acted global participation with an estimated $20 billion in on-chain prediction market volume tied to the tournament, $5.7 billion of that wagered during the five-week competition itself and 63% of all prediction market activity in that window.
Nearly 400,000 wallets took part, led by American and Chinese users, with Canada, Thailand and the UK rounding out the top five.
Kalshi separately disclosed $22.42 billion in World Cup-specific volume on its own platform alone, while Polymarket's international exchange confirmed a record $10.8 billion for June.
Combined prediction market activity across the tournament topped $50 billion dwarfing the $2.8-4.3 billion U.S. legal sportsbooks were projected to handle across all 104 matches.
The human cost was included inside those totals. A Polymarket trader known as gud.hl staked an estimated $1.23 million on Argentina across 28 trades, built largely from an earlier $1.9 million win trading TRUMP tokens, according to wallet tracing by Bubblemaps.
At one point the position was worth over $5 million on paper. Then Ferran Torres scored in the 106th minute, Spain won 1-0, and the entire stake went to zero one of the largest single losses of the tournament, flagged in real time by on-chain sleuths at Arkham on X.
The compliance angle from Chainalysis checks out too as Less than 1% of wallets tied to World Cup prediction markets showed links to illicit activity, although roughly $5.4 million still passed through sanctioned addresses. FIFA Collect, meanwhile, recorded $24 million in NFT trading, with sanctioned wallets making up under 0.01% of its user base. According to Chainalysis, those identity checks appear to be doing their job.
More than anything the World Cup confirmed that prediction markets aren't just a niche experiment anymore. Kalshi picked up 3 million users in just five weeks. Polymarket saw a record number of contracts traded on a single match. And traders like gud.hl make it pretty clear that the appetite for volatile, highly liquid markets, the same one that once powered memecoins and NFTs frenzies hasn't disappeared, it has simply moved to the next liquid, fast-moving market.
