A Polymarket trader known as “fishalive” turned approximately $428,000 into more than $4.7 million in just 90 minutes after betting against Spain winning its FIFA World Cup match against Cabo Verde. The trade was placed ahead of Spain’s June 15 World Cup fixture, where prediction markets gave the European side roughly a 90% chance of victory. Instead of backing the favorite, the trader purchased shares in the “No” outcome, effectively wagering that Spain would fail to win. When the match ended in a surprise scoreless draw, the position paid out at full value, generating more than $4 million in profit from a single market. According to data shared by Arkham Intelligence , ‘fishalive’ bought millions of shares in the outcome that Spain would not win. The market was priced at around $0.09 per share before kickoff, reflecting the low probability assigned to the result. Crypto trader World Cup 2026 prediction.
