The 2026 World Cup debuts the expanded 48-team format, the first time the tournament has used it. The field is split into 12 groups of four, with the top two from each group plus the eight best third-placed sides advancing to a new round of 32, so 32 teams reach the knockout phase. 1
The expansion stretches the tournament to 104 matches, against 64 at the last World Cup, and inserts an extra knockout round. A team must now win two elimination games rather than one to reach the quarter-finals, which lengthens the path for the favourites and gives outsiders one more shot at an upset. The group stage alone runs to 27 June. The opener on 11 June is the first of three simultaneous national ceremonies, in Mexico City, Toronto and Los Angeles.
The IFAB, the body that writes football's laws, also brought in three rule changes for this tournament, including red cards for goalkeepers covering the ball with the mouth and a VAR review for second yellow cards . Between the new bracket and the new laws, the 2026 edition changes how teams progress and how matches are refereed in the same week it kicks off.
