The 2026 World Cup began Friday with co-hosts Mexico and the U.S. launching their campaigns in an expanded tournament [1].

This tournament represents a significant shift in the global game, as the expanded format and shared hosting duties among the U.S., Canada, and Mexico create unique home-field advantages for the North American sides.

For the first time, the tournament features 48 national teams [1]. This increase in participants alters the group stage dynamics and extends the path to the final. Mexico enters the competition with high expectations, with some analysts saying the team could win the title while playing in front of home crowds.

Mexico's opening match takes place at Estadio Azteca in Mexico City against South Africa [1]. The venue is a historic fortress for the national team, and the co-host advantage is expected to play a critical role in their early momentum.

The U.S. men's national team opens its journey in Group D on June 12, 2026, facing Paraguay [2]. Tactical preparations for the U.S. have centered on managing the pressure of the opening match and optimizing their lineup for the group stage. Analysts have said the team's tactical flexibility is key as they attempt to navigate a competitive group.

The tournament is co-hosted across the U.S., Canada, and Mexico [3]. This distribution of matches across three nations is designed to maximize accessibility and fan engagement across the continent. While the U.S. focuses on tactical execution against Paraguay, Mexico aims to leverage the atmosphere of Estadio Azteca to establish dominance early in the tournament.

The 2026 World Cup will feature 48 national teams

The transition to a 48-team format increases the volatility of the group stages, making the home-field advantage for the U.S. and Mexico more critical than in previous editions. By hosting the opening matches in iconic venues like Estadio Azteca, the co-hosts are attempting to convert regional passion into a competitive edge to advance deep into the knockout rounds.
