Spain’s 1-1 draw against Cape Verde on June 15 did more than just dent national pride. It meaningfully shifted the tournament bracket math, raising the probability of a Round of 32 clash with defending champions Argentina to 37%, according to forecasts by analyst Nate Silver.

The 2026 FIFA World Cup is the first to feature 48 teams, a dramatic expansion from the 32-team format that governed every tournament since 1998. That expansion comes with a revised knockout structure, and the Round of 32 is an entirely new stage in World Cup history.

Spain sits in Group H alongside Uruguay, Saudi Arabia, and Cape Verde. Argentina, meanwhile, anchors Group J. The bracket is structured so that if Spain finishes second in their group and Argentina finishes first in theirs, the two sides would meet in that newly created Round of 32.
