Spain was held to a draw by Cape Verde, Jucom predicts the market will witness the biggest upset in history

On June 16, Beijing time, the first round of Group H in the 2026 FIFA World Cup™ saw the biggest upset since the tournament began. The title favorite, Spain, was held to a 0-0 draw by World Cup debutants Cape Verde despite dominating the match with 27 shots and a 74% possession rate. This was also the first match of the tournament to end with no goals.

Before the match, global prediction markets overwhelmingly favored Spain to win. According to Jucom prediction market data, as of June 15, the probability of Spain winning was as high as 92%, the probability of a draw was 6.3%, and the probability of Cape Verde pulling off an upset victory was only 2.6%. However, the actual match result sharply contrasted with the market's high expectations, leading to significant fluctuations in the prices of related topics in the prediction market.

Divergence Between Match Progress and Market Expectations

From the match data, Spain had 27 shots in total, with 7 on target, and an expected goals count of 2.16. Cape Verde had only 27% possession, with just 5 shots and 1 on target. However, Cape Verde's 40-year-old goalkeeper, Vozinha, made 7 saves and was named the player of the match.

Spain's head coach, De la Fuente, stated after the match that the team controlled the game but lacked scoring efficiency, emphasizing that there are still 7 matches to play. However, the immediate reaction from the prediction market indicated a noticeable decline in confidence among market participants regarding Spain's future performance.

Pricing Logic of Prediction Markets in Events

The core mechanism of prediction markets is to reflect the collective judgment of the market on the probability of an event occurring through trading prices. In the match between Spain and Cape Verde, the pre-match 92% winning probability indicated that market participants believed Spain's victory was almost a certainty. However, when a low-probability outcome occurs, all related prediction topics need to be repriced.

Taking the Jucom prediction market as an example, after this match, several dimensions of market expectations are undergoing significant adjustments:

• First, the probability of Spain finishing first in the group. In Group H, Spain was originally considered to have locked in the top spot with little doubt. However, after this draw, Spain has only accumulated 1 point and will face Uruguay and Saudi Arabia next. The market needs to reassess Spain's competitive position in the group and the potential risks to their group ranking.

• Second, the interconnected adjustment of Spain's championship probability. Spain was one of the top favorites to win the tournament alongside France before the World Cup. A draw against a lower-ranked team, while not affecting their qualification significantly, will prompt the market to reassess the team's offensive efficiency and overall form. The pricing of championship probabilities will reflect this change.

• Third, Cape Verde's probability of advancing from the group is beginning to recover from a near-zero low. As a World Cup debutant, Cape Verde earned its first point in history. This result has led the market to start reevaluating the team's competitive space in Group H, especially as the outcomes of other group matches are not yet fully clear, the expectations for Cape Verde's subsequent matches against Uruguay and Saudi Arabia will also be adjusted.

Upset Events Reveal Market Efficiency and Limitations

The outcome of this match provides a noteworthy case for participants in prediction markets. When the market has a highly consistent expectation for a particular result, the prices already reflect the known information. However, football matches inherently feature low scoring and high randomness, with factors such as unquantifiable on-field conditions, psychological resilience, and the boundaries of referee decisions potentially becoming key variables that affect actual outcomes.

The value of prediction markets lies not in accurately forecasting the result of every match, but in reflecting how market participants continuously incorporate new information into pricing through real-time changes. After Spain's draw, the market is quickly digesting this result and forming a new consensus regarding Spain's future performance and the situation in Group H.
