What markets predicted about key matchups

Before their quarterfinal clash, the market for 'USA advance vs Argentina' showed a clear discrepancy, with Kalshi listing USA at approximately 32% and Polymarket at 28–29%. Argentina ultimately defeated Switzerland 3–1 in the quarterfinals, having beaten Egypt 3–2 in the Round of 16. The USA had been eliminated in the Round of 16, losing 4–1 to Belgium.

Polymarket also tended to price Morocco to win the tournament 1–2¢ higher than Kalshi. Morocco's strong defensive performances saw them reach the quarterfinals, where they were defeated 2–0 by France.

Which contenders exceeded or fell short of market expectations?

Spain, trading around 20¢ pre-quarterfinals, proved to be significantly underpriced. They navigated a challenging bracket, including a semifinal victory over France and a 1–0 win against Portugal in the Round of 16, to eventually claim the championship.

Paraguay, priced around 5% to win the tournament before the quarterfinals, was a clear example of market overpricing. Despite their impressive penalty shootout victory over Germany, they were eliminated 1–0 by France in the Round of 16.

Germany's exit at the hands of Paraguay in the Round of 32 was a monumental upset on prediction markets. The outright contract for Germany plummeted from around 9% to 0¢ in less than 20 minutes.
