World Cup 2026 format explained: how the 48-team tournament works

World Cup 2026 introduces the largest men's World Cup format so far, with 48 national teams and 104 matches. Instead of the old 32-team structure, the tournament opens with twelve groups of four.

The format matters because it gives more countries a route into the biggest tournament in football. It also gives fans more games to follow, especially in the first two weeks when every time zone and host city will have its own storyline.

After the group stage, 32 teams move into the knockout rounds. That creates an extra layer of jeopardy because finishing first, second, or as one of the best third-placed teams can completely change a team's route.

For supporters, the best way to follow the new format is to track groups first, then bracket position. Once the knockouts begin, the tournament will feel familiar again: one match, one mistake, one moment.
