World Cup Prediction Markets Create Million-Dollar Winners & Losers

The 2026 FIFA World Cup is proving to be a massive event not only on the pitch but also across prediction markets, where traders have collectively wagered billions of dollars on tournament outcomes. As the group stage enters its final stretch, a series of stunning upsets has produced both enormous profits and painful losses for bettors using platforms such as Polymarket and Kalshi.

The World Cup has generated unprecedented activity in prediction markets. More than $5 billion has reportedly been traded across World Cup-related contracts on Polymarket and Kalshi, making it one of the largest prediction-market events ever recorded. The expanded 48-team tournament has created dozens of additional betting opportunities ranging from individual match results to group winners and outright champions.

The volatility has been a reminder of soccer’s unpredictability. Portugal’s surprising 1-1 draw against DR Congo and Spain’s stalemate against Cape Verde created massive swings in betting markets and generated several seven-figure payouts. Tuesday’s action saw another major loss for a soccer prediction market trader.

Huge Loss on England-Ghana Draw

Massive Prediction Market Losses Highlight World Cup Risk

Yahoo Finance highlighted how quickly fortunes can change in World Cup prediction markets this week. One trader reportedly lost nearly $1 million after backing Spain to defeat Cape Verde, a match that finished in a surprising 0-0 draw. Spain entered as one of the tournament favorites and was heavily favored in both traditional sportsbooks and prediction markets, making the result one of the biggest shocks of the group stage.

The losses extended beyond a single match. According to reports, another high-profile Polymarket trader lost approximately $4.2 million in less than 24 hours after placing massive positions on the Netherlands to beat Japan and Belgium to defeat Egypt. Both matches ended in draws, wiping out positions worth millions of dollars. One Belgium backer reportedly risked more than $8 million on a victory that never materialized.

These outcomes underscore a key difference between prediction markets and traditional investing. Heavy favorites may appear to offer low-risk returns, but even a draw can result in a complete loss on contracts tied to a specific match winner.

The World Cup’s group stage has already produced several surprising results, including Spain-Cape Verde, Portugal-DR Congo, Netherlands-Japan, and Belgium-Egypt, creating major swings in market prices and trader portfolios.

The volatility has not slowed interest in the market. Industry analysts estimate billions of dollars have already been traded on World Cup-related contracts across platforms, making the 2026 tournament one of the largest sporting events ever for prediction markets.
