The expanded 2026 FIFA World Cup format features 48 teams and 104 total matches, including a new round of 32 that creates 32 knockout fixtures where extra time applies if scores remain level after 90 minutes. Group stage contests allow draws and do not trigger extra time, concentrating potential ET outcomes in the single-elimination phase. Historical patterns from prior tournaments show ET occurring in roughly 15-25% of knockout games, influenced by competitive balance, defensive tactics, and fatigue in later rounds. With matches distributed across North American venues, factors such as travel, altitude, and heat could promote cautious play and higher draw rates in high-stakes ties. The opening round of group games begins today, setting the stage for progression into knockout rounds where these dynamics intensify.
