The new World Cup format explained - and why it changes everything for the underdogs

por Wosti -

The 2026 FIFA World Cup is the biggest in the competition's history. 48 teams, 104 matches, three host nations across North America, and a format that looks quite different to anything fans have seen before. For anyone looking to bet on FIFA World Cup 2026, getting to grips with how it works is crucial before the group stage begins.

The structural changes go deeper than the headline numbers suggest. How teams prepare, how coaches approach group games, and which nations have a realistic shot at the knockout stage have all shifted as a result.

In this article, we break down exactly what's changed and why the expanded format opens the door for underdogs in a way it never has before.

From 32 to 48 - what's actually different

The last time the World Cup format changed in any meaningful way was 1998, when FIFA expanded the tournament from 24 to 32 teams. That structure, eight groups of four, top two from each group advancing, ran through seven consecutive tournaments, including Qatar 2022.

This year it's been replaced by 12 groups of four. Every team still plays three group-stage matches, which keeps the rhythm familiar. What's changed is what happens next. The top two from each group advance automatically, as before. But now the eight best third-placed teams across all 12 groups also go through to a new knockout round, the Round of 32, before the traditional Round of 16 begins.

The third-place route

In the old format, finishing third meant going home. A team could win a match, draw another, and still be eliminated. There was no margin.

Under the new rules, eight of the 12 third-placed teams advance. Those spots are decided by points first, then goal difference, then goals scored across the group stage. Three points and a reasonable goal difference could now be enough to reach the last 32.

For teams from Africa, Asia, and the smaller football nations of the Americas, that's a meaningful shift. A spirited opening win or a hard-fought draw is no longer just a moral victory - it's a result that could carry a nation into the knockout rounds for the first time in their history.

What it means for the favourites

The format doesn't just benefit smaller nations. It adds an extra layer of pressure at the other end of the market too. The eventual champion must now win seven matches to lift the trophy, one more than in any previous 32-team tournament. Squad rotation matters more than it ever has.

There's also the question of when the real tournament begins. In the old format, a heavyweight could manage the group stage at something close to full pace before shifting up a gear at the Round of 16. Now there's an extra knockout game before that point. Spain, France, and England all have the depth to handle it. Teams with thinner benches, even well-fancied ones, face a tougher road.

Following the bracket

The group stage runs from June 11 to June 27, with the Round of 32 beginning on June 28. The final takes place on July 19 at MetLife Stadium in New Jersey. With 104 matches across 39 days and results coming in from across multiple time zones, tracking who needs what from the final round of group games is more complicated than in previous tournaments.
