Supporters of Mexico and South Africa gathered outside Estadio Azteca in Mexico City today for the opening match of the 2026 FIFA World Cup.

The event marks the start of a global tournament with expanded participation and a historic milestone for the host venue. As the first match kicks off, the world's attention turns to the expanded format of the competition.

This tournament represents a significant shift in the scale of the event. The 2026 FIFA World Cup features 48 teams and is scheduled to last 39 days [1]. This expansion increases the number of matches and the duration of the competition compared to previous iterations.

Estadio Azteca holds a unique place in soccer history with today's proceedings. The venue will become the first stadium to host three FIFA World Cup opening matches [2]. This achievement cements the stadium's status as a primary pillar of international soccer architecture.

Crowds of fans filled the areas surrounding the stadium, creating a festive atmosphere as they waited for the match to begin. Supporters from both nations arrived in large numbers to witness the opening clash between the host nation and South Africa.

The logistics of the 48-team tournament require a vast coordination of venues and schedules across the host regions [1]. The opening match serves as the primary catalyst for the month-long event, setting the tone for the remaining 38 days of play [1].
