The World Cup is the biggest event in global football, with nations across the planet dreaming of lifting the iconic trophy.
The tournament has changed in style and format over the years, though the 2026 edition has attracted attention for some key changes which may alter the playing schedule in a way we haven't seen for decades.
With all sorts of talk over the number of teams playing and the tournament's format, here's what you need to know.
How many teams will play at the 2026 World Cup?
In January 2017, the FIFA Council voted unanimously to increase the number of teams participating from 32 to 48. That decision was met with criticism, especially from organisations in Europe.
The European Club Association, La Liga president Javier Tebas and then Germany manager Joachim Low were among those who argued teams where already playing too many games.
It was also seen as a political decision from FIFA president Gianni Infantino, who had run his election campaign on the promise of involving more countries in the World Cup.
What is the format at the 2026 World Cup?
Given the increase of sides from the 2026 World Cup, a change of format is expected. The initial vote in 2017 declared there would be 16 groups each consisting of three teams, with the top two reaching the knockout stage which will include 32 teams.
The overall amount of matches will increase from 64 to 80, though the finalists will still only play seven games each under the proposals.
In late 2022, it was revealed FIFA are becoming open to keeping the current group stage process involving four teams each, with some revealing concerns over potential dead rubbers on the final matchdays of each group.
The three-game group stage proposal has attracted criticism. There have been concerns over a potential rise in collusion as seen in previous group matches.
The 1982 Disgrace of Gijon saw West Germany and Austria play out a 1-0 win for the Germans, allowing both sides to go through at the expense of Algeria, who had played earlier in the day. The game was met with outrage, though FIFA denied any wrongdoing on either side.
The 2022 World Cup delivered plenty of entertainment during the group stage, with Group D in particular throwing up drama in the Poland vs Argentina and Saudi Arabia vs Mexico games.
Qualification for a 48-team World Cup would also change as more teams can make the final cut. Asian, African and CONCACAF sides all have greater chances to reach FIFA's flagship event, while a spot for an Oceania side is now guaranteed.
Who is hosting the 2026 World Cup?
The USA, Canada and Mexico and jointly host the 2026 World Cup. 23 cities across the three nations will host games, with the US taking 60 matches. The joint bid comfortably saw off an effort from Morocco to host the tournament.
