World Cup Betting Shock: Trader Loses $1 Million on Spain Draw as Another Wins $4.7 Million

The 2026 FIFA World Cup has already delivered its share of surprises, but few have had a bigger impact on bettors than Spain’s stunning 0-0 draw against tournament newcomer Cape Verde.

The result was one of the biggest upsets of the opening week and produced both a seven-figure loss and a multi-million-dollar win on prediction market platform Polymarket. Spain entered the match as one of the favorites to win the World Cup and was listed as roughly a 92% favorite against Cape Verde, making the draw one of the most unexpected outcomes of the tournament so far.

Cape Verde’s defensive effort, led by veteran goalkeeper Vozinha, frustrated Spain throughout the match. Despite dominating possession and generating numerous scoring opportunities, Spain could not find a breakthrough, allowing one of the tournament’s most memorable underdog stories to unfold.

The $1 Million Loss

The most publicized betting loss of the tournament came from a trader who wagered approximately $999,000 on Spain to defeat Cape Verde. Because Spain was such a heavy favorite, the bettor stood to make a relatively modest profit compared to the size of the wager, with a potential return of roughly $85,000. Instead, the draw wiped out the entire position.

The loss quickly became one of the most discussed betting stories of the World Cup. Spain entered the match unbeaten in major competition for more than two years and was widely considered one of the strongest teams in the tournament. Cape Verde, meanwhile, was making its World Cup debut and entered as a massive underdog.

Compounding the frustration for Spain supporters, the match statistics overwhelmingly favored the European champions. Spain controlled possession, outshot Cape Verde by a wide margin, and generated significantly more expected goals but still failed to score.

The $4.7 Million Winning Bet

While one trader suffered a devastating loss, another enjoyed one of the biggest wins of the tournament. A Polymarket user reportedly wagered $427,000 on Spain not to win the match, a position that paid out more than $4.7 million after the final whistle.

The trade represented the opposite side of the same market and demonstrated how prediction markets can generate enormous payouts when unlikely outcomes occur. Some reports estimated the profit exceeded $4 million in less than two hours as Cape Verde held on for the historic result.

The outcome immediately became a showcase example of the risk and reward associated with prediction-market trading, particularly during global events such as the World Cup.

World Cup Betting and Prediction Market Growth

The Spain-Cape Verde result highlights the enormous amount of money flowing into both traditional sportsbooks and prediction markets during the World Cup. Industry analysts have projected that legal betting handle in the U.S. alone could exceed several billion dollars during the tournament, while global wagering is expected to reach tens of billions.

Prediction-market operators such as Polymarket and Kalshi have also seen significant trading volume tied to match results, group winners, Golden Boot races, and outright championship markets.

The expanded 48-team format has created additional betting opportunities and increased interest in underdog markets. Early draws involving Spain, Belgium, Brazil, Uruguay, and the Netherlands have demonstrated how quickly futures markets and group odds can shift during the opening stages of the tournament.

As the World Cup moves deeper into the group stage, bettors and traders will continue looking for value opportunities. If the opening week is any indication, surprises remain plentiful, and the next major prediction-market windfall could be just one unexpected result away.
