In the 2027 edition, the format will be changed to accommodate an expanded 14-team final competition. In the tournament phase, 10 teams, including the automatically qualifying host nation, compete for the title at venues within the host nation over about a month. The current format involves a qualification phase, which takes place over the preceding three years, to determine which teams qualify for the tournament phase. From the 1987 tournament onwards, hosting has been shared between countries under an unofficial rotation system, with fourteen ICC members having hosted at least one match in the tournament. The first three World Cups were held in England.

However, a separate Women's Cricket World Cup had been held two years before the first men's tournament, and a tournament involving multiple international teams had been held as early as 1912, when a triangular tournament of Test matches was played between Australia, England and South Africa. The first World Cup was organised in England in June 1975, with the first ODI cricket match having been played only four years earlier. The tournament is one of the world's most viewed sporting events and is considered the 'flagship event of the international cricket calendar' by the ICC. The event is organised by the sport's governing body, the International Cricket Council (ICC), every four years, with preliminary qualification rounds leading up to a finals tournament. The Cricket World Cup, officially known as ICC Men's Cricket World Cup, is the international championship of One Day International (ODI) cricket.
