From the Changes in Championship Odds, Key Points in the First Round of Group Stage

The World Cup has already started, and every match in the first round of the group stage is not just about 3 points, but also directly impacts each team's morale and the difficulty of subsequent matches. Meanwhile, the championship odds on prediction platforms like Polymarket are fluctuating in real-time, hiding a wealth of valuable information behind these movements. Today, I will analyze the current odds landscape of the championship market and highlight some key points to watch in the first round of the group stage.

As of June 12, the top six teams in the Polymarket World Cup championship market and their implied probabilities are: Spain 16.5%, France 16.1%, England 11.2%, Portugal 10.8%, Brazil 8.9%, Germany 8.0%, Argentina 6.7%. Compared to a week ago, Spain has risen by 0.8 percentage points, France has fallen by 0.3 percentage points, and Argentina has dropped by 1.2 percentage points. Spain's rise is mainly due to their strong performance after a 4-0 warm-up victory over Andorra, as well as the health status of key players (Pedri, Gavi, Yamal, and other young players are all available). The slight decline in France is due to Mbappé suffering a minor ankle sprain during training, which is not expected to affect the group stage, but market funds have still shown some concern.

Argentina's decline is the most obvious. Why? Because Argentina's midfield aging problem was thoroughly exposed in recent warm-up matches. The 34-year-old Paredes and 33-year-old De Paul can no longer cover the entire midfield area like three years ago. Although Messi's individual ability remains top-tier, he must distribute his physical energy more cautiously. Moreover, Argentina's group draw is not favorable—if they qualify as second in the group, they might face Spain in the round of 16, which is a matchup they would prefer to avoid. Market funds have clearly noticed these risks, lowering Argentina's championship probability by over 1 percentage point.

Several matches in the first round of the group stage will directly influence the subsequent trend of championship odds. The first is Spain vs. Croatia (June 16). If Spain can decisively beat Croatia, their odds are likely to surpass 18%, further solidifying their leading position; conversely, if they drop points unexpectedly, France and England could overtake. Next is France vs. the Netherlands (June 17), a potential preview of the final, where Mbappé and Van Dijk's duel will directly impact market evaluations of both teams. Lastly, England vs. Serbia (June 17). If England performs poorly, market confidence in them could drop sharply, as they have had results in recent major tournaments but still lack convincing strength.

For us users participating in prediction activities at Gate Square, changes in championship odds are a valuable information source. However, I do not recommend directly betting on the championship market—because the timeline is too long, and variables are too many, making the capital efficiency for ordinary players very low. A better strategy is: observe the flow of funds in the championship market with small positions, then feed this information back into specific group stage predictions. For example, if Spain's odds rise rapidly in a short period, it indicates a lot of smart money is buying Spain, which could mean positive internal news (such as players in top form, excellent training performance). In that case, Spain's opening match in the group stage deserves extra attention.

Finally, a reminder: predicting the World Cup is not a guessing game but an information war. Pay close attention to the flow of funds on Polymarket, compare odds across different platforms, and think more about the underlying logic. Your prediction accuracy will gradually improve.
