Polymarket’s $3.3B World Cup boom exposes the longshot trap inside prediction markets

An important story is making waves across the blockchain ecosystem. Prediction markets are drawing one of their largest sports audiences yet from the World Cup, but the surge is creating an unusual picture beneath the headline numbers. World Cup-linked contracts on Polymarket have generated more than $3. 3 billion in trading volume, a level that puts the tournament well ahead of this year’s Super Bowl, which drew about $1.

4 billion in prediction-market trading. The comparison reflects how quickly event-based trading has moved into major sports, with soccer’s global reach giving platforms a much larger and longer runway than a single championship game. Meanwhile, the boom is not limited to Polymarket.

Market Dynamics

Kalshi and other prediction-market venues are also seeing heavy activity tied to match results, tournament outcomes, and related soccer contracts. Yet the trading activity is not flowing cleanly toward the teams most likely to win. As the tournament moves into the Round of 32, prediction markets are showing two stories at once: a narrow race between the top contenders and a large amount of capital still attached to teams priced as extreme longshots.

France and Argentina set the pace France has become the market’s narrow favorite to win the 2026 FIFA World Cup, with Argentina close behind. On Polymarket, France is priced at a 23% chance of winning the tournament. Argentina follows at 21%, leaving the two finalists from the 2022 World Cup almost level at the top of the board.

Spain is third at 11%, England is fourth at 10%, and Brazil is fifth at 6%. World Cup Winner Bets on Polymarket (Source: Polymarket)The same pattern is visible in the market for teams to reach the final. France leads that contract with a 39% implied chance, while Argentina is second at 38%.

Market Impact

Spain follows at 23%. That positioning suggests traders are increasingly preparing for the possibility of another France-Argentina final, four years after the Messi-led Argentine team lifted the trophy in Qatar. The volume around the leading teams also reflects that concentration of attention.

Argentina has drawn about $81 million in winner-market trading, while France has attracted about $77 million. Portugal has seen roughly $76 million, Spain about $68 million, and England about $61 million. Those numbers show a clear demand for the favorites, but they do not explain the largest imbalance on the board.

Longshots carry billions in volume About $1. 6 billion has been traded on teams with an implied winning probability of 1% or less. That figure accounts for roughly two-thirds of the trading on the winner market, even though those teams are priced as having little realistic path to the title.

Crypto markets are watching this development closely as investors weigh its potential impact on prices.
