Mexico enters the 2026 FIFA World Cup as co-host with a clear edge in Group A, reflected in the market's 55.5% implied probability. Home matches at high-altitude venues like Estadio Azteca and Guadalajara provide a significant boost through fan support and environmental factors, while the opening fixture against South Africa offers an accessible start. South Korea and Czechia sit at 21.5% and 18.5% respectively due to their established international experience and competitive head-to-head records, though both face tougher travel and adaptation challenges. South Africa trails at 6.3% amid limited recent form against stronger opposition. With group matches beginning June 11, these probabilities capture the wisdom of crowds weighing host advantages against the other sides' potential for points in a compact schedule.
