Mexico's co-host status and established squad depth position the team as the clear frontrunner in Group A, reflected in trader consensus around a 52 percent implied probability. The expanded 48-team format and three matches in familiar conditions at venues like Estadio Azteca provide measurable edges in rest, travel, and crowd support compared to Czechia, South Korea, and South Africa. Recent previews highlight Mexico's consistent group-stage qualification record and depth across midfield and attack, while Czechia and South Korea trade narrow advantages in recent Nations League and Asian Cup results. South Africa remains the longest shot given limited recent competitive exposure against top CONCACAF and UEFA sides, though the expanded knockout qualification path keeps all four teams mathematically alive heading into the June 11 opener.
