The 2026 FIFA World Cup logo it's definitely the most modern approach have've seen so far. Traditionally, the World Cup logo has been designed to reflect the culture of the host nation(s) in some way, but that is not the case here, removing any hint of the hosts' culture or national identity.
The official emblem and brand identity was unveiled on May 17, 2023, at the Griffith Observatory in Los Angeles, California; its basic form consists of a stacked "26" with an image of the FIFA World Cup Trophy in front of it, but it is designed to be adaptable to different backdrops. Each of the host cities also have their own brand identities for the tournament, the colours can be customised to fit the various host cities and will fit into a wider visual branding scheme that uses the same design language.
