FIFA, the event's official organizer, has confirmed that the 2026 FIFA World Cup would include 48 teams, making it the biggest ever. According to their website, the competition, which is co-hosted by the USA, Canada, and Mexico, will have 48 teams instead of the customary 32, making it the largest World Cup ever. Major sports organizations like ESPN and the BBC support this information as well by using FIFA's official statements. In order to boost worldwide participation and commercial success, the decision to expand was made public in 2017. This claim is reliable and well-supported because FIFA is the official source and has a vested interest in promoting the event, as confirmed by other respectable media.
