The 2026 World Cup is co-hosted by the two halves of CONCACAF's defining feud. Mexico against the United States is the rivalry that built football in this region — and this summer their stadiums share the world's biggest tournament.

The fixture has its own mythology. Mexico's fortress, the Estadio Azteca — where the 2026 tournament opens — has tormented visiting American sides for generations with its altitude and noise. The USA built a counter-legend of their own: "Dos a Cero," the 2-0 scoreline that became their trademark in World Cup qualifying meetings in Columbus.

El Tri have historically owned the region's silverware, while the modern era has seen the USA strike back in Nations League and Gold Cup finals. What has never changed is the intensity: no CONCACAF fixture — not even the Caribbean clásico — carries this weight.

Both hosts open at home this month with the world watching. Start with the key matches guide and the stars to watch, and follow every game on the full schedule.
