19 million on Sweden to win and Japan not to win their match. The game ended 1-1, a result that paid out and earned the trader about $4.38 million.

The same trader then staked $2.26 million on Ecuador to beat Germany, with the combined day’s haul reaching $8.47 million.

Such figures aren’t really unusual, given that crypto-based prediction markets have turned into a high-stakes arena in recent months with matches resolving in real time and traders swinging millions on a single goal. Last week, one bettor using the handle “fishalive” turned a $400,000 bet into a $4.7 million payout by correctly wagering that Spain would not beat Cape Verde, an outcome priced at just 9% before kickoff.

The two sides played to a draw in what observers called one of the tournament’s most stunning results. On the flipside, a trader lost roughly $4.2 million across two positions in under 24 hours, first staking millions on the Netherlands to beat Japan, which ended 2-2, then on Belgium over Egypt, which slipped away on an own goal.

The same Cape Verde upset that minted fishalive’s profit cost another trader nearly $1 million on a single Spain wager. The Platform Behind the Boom Much of the World Cup action has concentrated on Polymarket, the largest onchain prediction market, where sports betting has become a major draw alongside politics and economics. The platform and rival Kalshi helped drive a record stretch for the sector earlier this year, with prediction markets logging tens of billions of dollars in monthly volume.

That visibility has been a double-edged sword, though, because the same week the World Cup trades drew attention, Polymarket revealed that hackers had stolen about $3 million from users through a compromised third-party vendor. The company said it had successfully contained the breach and is now actively refunding affected users. In any case, the World Cup continues to supply the kind of dramatic, publicly traceable trades that have made prediction markets a spectacle of their own.

Whether the $8.47 million day stands as a tournament high or is eclipsed by an even larger bet may come down to the next unexpected result.
