The first four fixtures of the 2026 World Cup’s inaugural round of 32 were locked in on Thursday, as the group stage began to yield definitive results. South Africa, runners-up in Group A, will face Canada, second in Group B, at SoFi Stadium in Los Angeles on 28 June. A day later, Brazil, winners of Group C, meet Japan, the Group F runner-up, in Houston, while the Netherlands, top of Group F, take on Morocco, second in Group C, in Monterrey. The United States, as Group D winners, will then host Bosnia and Herzegovina, one of the eight best third-placed teams, at Levi’s Stadium in Santa Clara on 1 July. These four ties are the only certainties in a knockout bracket that remains largely a mathematical puzzle, a direct consequence of the tournament’s new 48-team, 12-group format.

For Argentina, the wait is especially acute. Having already secured first place in Group J, Lionel Scaloni’s side knows it will play the Group H runner-up on 3 July at Hard Rock Stadium in Miami. That identity will be decided on Friday night when Spain, the group leaders on four points, face Uruguay (two points) in Guadalajara, while Cape Verde (two points) and Saudi Arabia (one point) meet in Houston. Viewed from Buenos Aires, the permutations heavily favour Cape Verde, which has a 55 per cent probability of finishing second according to projections cited across the Americas. The African debutants, who held Spain to a goalless draw and then came from behind to tie Uruguay 2-2, need only to beat Saudi Arabia and hope Spain avoid defeat. Saudi Arabia has a 29 per cent chance, while Uruguay, despite its pedigree, has just a 6 per cent shot at the runner-up spot. A Spain loss combined with a Cape Verde victory could even drag the 2010 world champions into second place, though their 84 per cent probability of topping the group suggests that outcome is remote.

The broader bracket remains clouded by the eight best third-placed teams, a novelty that prevents the full draw from being completed until every group has finished. Mexico, for instance, won Group A with a perfect nine points but will not learn its opponent until the matrix of third-placed qualifiers is finalised; it could face a side from any of five different groups. Germany, Switzerland, and the United States are in similar limbo. Analysts in Europe note that the FIFA-designed system, which uses a pre-set table of combinations to assign third-placed teams to specific group winners, is designed to prevent collusion and ensure that no team can choose its opponent by manipulating a result. The cost is a prolonged period of uncertainty: before the final matchday, there were 495 possible scenarios for the third-placed qualifiers alone.

That uncertainty will dissolve rapidly. The last group-stage matches, including the decisive Group H double-header, will be played on Friday and Saturday. Once the final whistles blow, FIFA will release the complete bracket, slotting the eight best third-placed teams into their designated ties. For Argentina, the immediate consequence is clear: a Friday night spent watching two simultaneous kick-offs, knowing that a Cape Verde victory would likely send the island nation to Miami and set up a historic first meeting between the sides. For the rest of the field, the next 48 hours will transform a web of probabilities into a concrete path to the final at MetLife Stadium on 19 July.
