Spain's 92% "Sure Thing" Turns Into a $9 Million Polymarket Heist 🐟

A days-old Polymarket wallet called "fishalive" turned roughly $4 million into a profit of more than $9 million in a matter of hours on Monday after FIFA World Cup debutants Cabo Verde held tournament favorite and European champions Spain to a 0-0 draw at Mercedes-Benz Stadium in Atlanta. The match had started with Spain priced at about 92% on the prediction market, implying 1:10 odds against the island nation ranked 67th in the FIFA standings.

According to on-chain analytics firm Lookonchain, the fishalive account placed two bets against Spain: that Spain would not win outright and that Cabo Verde would stay within a 2.5-goal spread. When the final whistle confirmed a 0-0 scoreline, the wallet redeemed about $4,738,433.49 on the Spain "No" market and roughly $8.5 million on the spread, per Polymarket's public trading record. The user's profile, which joined the platform in June 2026 with just two total predictions, had bought more than 4.7 million "No" shares at an average price of 9¢ each, a position that priced Spain's chances of losing or drawing at around 9%. The profit on the day came to about $4.3 million on the head-to-market alone, with the spread leg lifting the combined gain to roughly $9 million.

On the other side of the ledger, a Polymarket trader using the name "betoor619" lost close to $1 million. The bettor had put almost $1.1 million on a Spain win at 92% implied odds, for a potential payout of only about $85,000, the thin reward typical of backing near-certain outcomes. Polymarket Sports flagged the wager before kickoff, noting the position would have returned $1,085,943.48. The bettor's account had never won or lost more than $9,000 on a single event before, according to the platform's history.

Cabo Verde's 40-year-old goalkeeper Josimar Évora, known as Vozinha, was named player of the match after finishing with eight saves, including a stop on a Ferran Torres shot in the corner and a push of a Mikel Oyarzabal header over the crossbar. Torres also struck the crossbar from what ESPN described as Spain's best chance of the game, while star Lamine Yamal was unable to break through. The final shot count read Spain 27, Cabo Verde 6, a disparity that did not translate onto the scoreboard.

Cabo Verde had advanced through Confederation of African Football (CAF) qualifying with seven wins, two draws and a single defeat, avoiding the inter-confederation playoffs entirely. Vozinha, a veteran of the Portuguese league, anchored a defense that neutralized a Spain side that had beaten England, France and Germany in recent memory. The result immediately drew comparisons to the biggest upsets in World Cup history, and memes referencing the "surest bet in sports" circulated on X within minutes of the final whistle.

Polymarket operates as a prediction market where users trade shares tied to real-world outcomes, with prices acting as implied odds and settlement in USDC. The fishalive and betoor619 trades now rank among the most extreme single-match outcomes recorded on the platform this tournament, underscoring both the leverage available to anonymous onchain bettors and the risk that heavy favorites can carry when priced near certainty.
