An anonymous Polymarket trader known as “fishalive” booked a roughly $9 million profit on about $4.2 million of bets against Spain on Monday, cashing in on one of the biggest upsets in World Cup history.
Spain came in as the reigning European champion and a tournament favorite, priced near 92% to beat Cabo Verde on Polymarket and given a 26% chance to lift the trophy by a Goldman Sachs model.
Cabo Verde, an archipelago of about half a million people off the coast of West Africa, had never before qualified for a World Cup and fielded no stars.
The debutants held the champions to a scoreless draw.
