How Group J ultimately finished

How far did each team from Group J go at the 2026 World Cup?

Argentina, after winning Group J, made a remarkable run to the final, ultimately finishing as runners-up after a 1-0 (AET) loss to Spain. Austria also advanced from the group stage but exited in the Round of 32 after losing 3-0 to Spain. Algeria and Jordan were eliminated in the group stage.

Argentina's pre-tournament pricing as a strong favorite in Group J proved accurate, though their ultimate journey to the final was a testament to their strength throughout the tournament.

What the Group J market teaches

Argentina's dominance in Group J was largely anticipated by markets, with their contracts trading as high as 75¢ to win the group before kickoff. Austria, despite being considered the second strongest, faced a tough opponent in the Round of 32 in eventual champions Spain. The pre-tournament 'Rangnick premium' for Austria's Round of 16 prospects, which saw their contracts trade 2-3¢ richer than implied, did not translate into a deeper run.

Key Group J fixtures and their impact

The matchday 2 encounter between Argentina and Austria was indeed a crucial fixture, as predicted. Argentina entered as strong favorites in that single fixture, around 70-78¢, and their performance in that match helped solidify their position atop the group.

The third-place scenario: advancement under the 48-team format

Algeria's reach-Round-of-32 contract traded around 30-38¢ before the tournament, driven by confidence in their CAF attacking core. Jordan's advancement contract was the cheapest among AFC debutants. Under the expanded 48-team format, where the eight best third-placed finishers advanced, neither Algeria nor Jordan managed to secure a spot in the Round of 32, highlighting the competitive nature of even the expanded knockout stages.
