48 teams are split into 16 groups of 3. Each team plays two group matches. The top 2 from each group (32 teams) plus the 8 best third-placed teams (40 total — wait, actually: top 2 from each group = 32 teams advance to the Round of 32). Note: FIFA later confirmed 12 groups of 4 for the final format — the top 2 and best 8 third-placed teams = 32 advance. This is the most dramatic format change in World Cup history.
Round of 32 → Round of 16 → Quarterfinals → Semifinals → Third-place playoff → Final. Total matches: 104 (up from 64 in 2022). The longer tournament means more fixture congestion risk for players but more spectacle overall. Third-placed group finishers now face pressure: every point in the group stage matters since 8 of the 16 third-placed teams advance based on a points/goal-difference table.
5 substitutions allowed per team (same as 2022). VAR continues, expanded to include more decision categories. Goal-line technology at all 16 venues. New: semi-automated offside technology speeds up decisions. The extended squad sizes (26 players) remain from Qatar 2022.
The 2026 World Cup will feature 104 matches — a significant increase from the 64 games at the 2022 Qatar World Cup. This is the result of expanding from 32 to 48 teams.
The top 2 teams from each of the 16 groups advance automatically to the Round of 32. Additionally, the 8 best third-placed teams also advance, meaning 40 of 48 teams proceed from the group stage.
