Mexico enters the 2026 FIFA World Cup as Group A co-host with the strongest implied probability at 57.5 percent, reflecting superior squad depth, recent international form, and the significant home-crowd advantage across its three group matches. South Korea sits second at 20.5 percent on the strength of its balanced roster and proven experience in major tournaments, while Czechia trails at 17.5 percent due to its physical style and solid UEFA qualification path but limited depth against top competition. South Africa rounds out the field at 6.1 percent as the clear underdog, relying on defensive organization but facing a steep challenge in advancing from the section. These trader-consensus probabilities align with pre-tournament assessments of roster quality and situational edges ahead of the June 11 opener.
