Polymarket Data Deep Dive — Is France's 60% Win Probability Reasonable?

Polymarket prediction market data shows France's win probability at about 60%, Norway at about 20.5%, and a draw at about 20%. However, this data needs to be interpreted within a specific context — prediction markets reflect capital flows and market sentiment, not purely mathematical model predictions.

PolyMarket data shows that France's win probability has slightly declined from 65% to 60% over the past week, while Norway's win probability has risen from 18% to 20.5%. This change reflects market concerns about possible rotation in the French squad and the absence of Deschamps. Trading data shows that the trading volume for France winning has reached approximately $2.5 million, accounting for 63% of total volume. The draw's trading volume is about $800k, accounting for 20% of total volume. Norway's win trading volume is about $700k, accounting for 17% of total volume.

A notable detail: against the same opponents (Iraq and Senegal), Norway's actual goal tally (7 goals) surpassed that of France (6 goals). Norway won all 8 matches in the qualifying stage, defeating Italy twice, with a goal difference of +32. France went 6 wins and 2 draws in qualifying, with a goal difference of +18. Norway created more chances (10 big chances) in the first two group stage matches than France (8). These objective statistics do not seem to support France's 60% win probability — at least, the actual performance gap between the two teams is not as wide as 60% versus 20%.

The deviation in market data may stem from the following factors:

Brand Effect: France is the runner-up and champion of the past two World Cups, so the market naturally has higher trust in the French team. France is the favorite to win the tournament, while Norway is just a dark horse.

Superstar Effect: The popularity of stars like Mbappé and Dembélé is higher than that of Haaland and Ødegaard (although Haaland is equally top-tier). The superstar effect is often overvalued in prediction markets.

Inertia Thinking: France is a traditional powerhouse, while Norway is a newcomer returning to the World Cup after 28 years. The inertia of historical prestige makes the market lean toward France.

Rotation Uncertainty: There is disagreement in the market regarding France's rotation. Some traders believe France will go all-out, while others expect significant rotation. This divergence weakens the accuracy of France's win probability to some extent.

Some analysts believe that Norway's value at approximately 5x odds is severely underestimated. Norway's offensive firepower and motivation to win are extremely strong, while France faces variables such as rotation and the absence of the head coach. If France rotates heavily, Norway's chances of winning will increase significantly.

In any case, Polymarket data reflects market consensus. But market consensus is not equal to objective probability. Rational analysis should find a balance between market sentiment and objective data. #挪威VS法国
