Woofun AI reports that Polymarket has processed $3.3 billion in trading volume for the World Cup, a figure that exposes a critical structural anomaly known as the longshot trap within modern prediction markets. This surge demonstrates how event-based trading has rapidly migrated into major global sports, leveraging soccer's extensive international reach to create a runway far exceeding the scope of a single championship game. The phenomenon is not isolated to one platform; Kalshi and other prediction-market venues are simultaneously recording heavy activity linked to match results, tournament outcomes, and specific soccer-related contracts. On the Polymarket board, France is currently priced at a 23% chance of winning the tournament, while Argentina follows closely at 21%, leaving the two finalists from the 2022 World Cup nearly level at the top of the leaderboard. Spain occupies the third position at 11%, England sits fourth at 10%, and Brazil trails in fifth at 6%. This specific pricing structure suggests traders are increasingly positioning for the possibility of a repeat France-Argentina final, four years after the Messi-led Argentine squad secured the trophy in Qatar. The trading volume surrounding these leading teams further reflects this intense concentration of market attention. Argentina has drawn approximately $81 million in winner-market trading, while France has attracted about $77 million. Portugal has seen roughly $76 million in activity, Spain about $68 million, and England about $61 million. These figures clearly indicate robust demand for the favorites, yet they fail to explain the most significant imbalance currently visible on the board. Approximately $1.6 billion has been traded on teams with an implied winning probability of 1% or less. This staggering figure accounts for roughly two-thirds of the total trading on the winner market, even though those teams are priced as having little realistic path to the title. Several of these heavily traded longshots still demonstrate massive historical volume despite their low odds. Ivory Coast has drawn about $101 million, Mexico has moved about $97 million, and Egypt has attracted roughly $90 million. Cape Verde is near $87 million, while Morocco has seen about $82 million in trading activity.

Additionally, some positions may be tied to longshot speculation, fan-driven buying, hedges, parlays, or trades that users have not yet closed. This dynamic leaves certain markets appearing far more active than current probabilities would logically suggest. The underlying mechanism is that money can remain attached to teams even after the market has largely moved on from them. Unlike a traditional sportsbook, where odds can reset around new betting lines, prediction-market contracts continue trading until settlement or until users explicitly exit their positions. The effect is especially clear when compared with the leading group of contenders. A basket comprising France, Argentina, Spain, England, and Portugal costs about 72 cents combined at current prices. If any one of those five teams wins the tournament, the position pays $1. This trade structure reflects how concentrated the market's confidence has become, even as billions in historical volume remain scattered across outsiders. In that sense, the World Cup board is not just a ranking of who is most likely to win; it is also a record of how traders moved through the tournament, where they entered early, which tickets became stale, and where liquidity has failed to unwind fully. Wall Street brokerage firm Bernstein projects that World Cup-related trading could ultimately surpass $10 billion in total wagers before the tournament concludes on July 19. This sporting catalyst is also having a measurable spillover effect on non-sporting contracts. According to the firm, this non-sports volume alone is now larger than the total aggregate volume of all prediction markets recorded just one year ago. In July 2025, weekly non-sports volume hovered near the $200 million mark, representing an 18-fold increase over the past 12 months.

Woofun AI data shows that for Polymarket, the investigation adds uncertainty after the platform resumed limited US operations last year. The company had previously been barred from serving US customers following a 2022 enforcement action. The timing is notable because it comes as prediction markets are posting record volumes, just as regulators are taking a closer look at how the sector operates, how consumers are protected, and where the line should be drawn between regulated event contracts and gambling.
