Stunning World Cup upset! Cape Verde holds title favorite Spain to a draw, with a Polymarket account losing nearly $1 million.

```

Cape Verde and Spain drew in the World Cup group stage, causing a prediction market trader to lose nearly $1 million.

In the early hours of June 16 (Beijing time), during the first round of Group H in the 2026 North American World Cup, Cape Verde—making its finals debut and with a squad valued at less than €55 million—held world number two Spain, whose squad is worth €1.22 billion and is a hot favorite for the title, to a 0-0 draw.

This result completely disrupted the prediction market odds and resulted in significant losses for several traders heavily betting on Spain. Polymarket data shows that one trader betting on a Spain win lost nearly $1 million.

Million-Dollar Bet: The Failure of a "Certainty" Strategy with Low Returns

According to Polymarket’s public trading records, a trader with the username "betoor619" established a large long position close to $1.1 million when Spain's win probability was about 92%.

If Spain had won, this user would have earned only about $85,000—a typical "low risk, low reward" strategy: betting on high-probability events with large capital to gain small, steady returns.

But ultimately, this user ended up with a loss of nearly $1 million.

Records show the account was opened last October, and prior single-event losses or gains never exceeded $9,000. This bet was over a hundred times greater than any of its previous trades.

Other traders also made large bets on a Spain win, but most also carried out hedging transactions to partially offset their losses.

Polymarket allows large traders to act as market makers, holding both long and short positions in the same wager—similar in mechanism to Wall Street institutions earning spreads by trading the same stock.

Behind the Upset: Cape Verde’s 40-Year-Old Goalkeeper Saves the Day

Spain was widely regarded as the hottest contender for the World Cup title.

Wallstreetcn noted Goldman Sachs’ model gave Spain a 25% probability of winning, highest among all teams. For Cape Verde, not only is it their first World Cup appearance, their squad contains no recognized professional players.

The key figure responsible for the turnaround was goalkeeper Josimar José Évora Dias, nicknamed Vozinha. The 40-year-old veteran made seven crucial saves during the match and walked off the pitch in tears afterwards, earning the Man of the Match award.

Vozinha said after the game that visa issues prevented his mother from witnessing this historic moment in person. According to relevant regulations, visitors from some countries, including Cape Verde, must pay up to $15,000 in refundable bonds. He described the match as the goal he has strived for in his "entire career".

This draw was also one of several upsets in the opening days of the World Cup; on Sunday, Japan staged a comeback and tied the Netherlands in stoppage time.

Platform Expansion: The Mainstreaming of Sports Betting from Political Wagers

Prediction market platforms like Polymarket have quickly moved beyond niche circles in recent years. Previously known mainly as tools for betting on geopolitical and economic events, they have now become popular platforms for betting on major worldwide sporting events like the World Cup.

Platform users trade via cryptocurrency wallets and can operate anonymously, without disclosing their real identity or location. This mechanism has drawn criticism from some lawmakers, who argue platforms do not collect necessary user background information like traditional brokers or bookmakers.

Public trading records also provide an observation window for outsiders, revealing the large scale and high risk of user bets on these events. In just the match between Spain and Cape Verde on Monday, Polymarket users traded a total of $64 million.
