The 2030 Men's World Cup will be a historic tournament, marking the centenary of the FIFA World Cup. It is scheduled to be hosted across three continents for the first time, with matches in Morocco, Portugal, and Spain serving as the primary hosts, and opening games in Uruguay, Argentina, and Paraguay to commemorate the 1930 tournament. The discussion about expanding the tournament from the current 48-team format (which debuts in 2026) to 64 teams has gained traction among FIFA officials and football stakeholders. This would represent a dramatic increase from the 32-team format used from 1998 to 2022, and would make the World Cup larger than any previous edition. The idea was first publicly floated by FIFA Vice President Ignacio Alonso in 2023, who suggested that the centenary edition could include every FIFA member association that qualifies, though this concept has not been formally proposed or voted on. FIFA President Gianni Infantino has been a proponent of expanding global competitions, having already pushed the World Cup from 32 to 48 teams for 2026. The 64-team format would require significant changes to the tournament structure, including more match days, additional host cities, and increased logistical demands. Critics argue that such expansion would dilute the quality of competition and strain players with an already congested calendar. Supporters point to increased revenue from broadcast rights and sponsorship deals, as well as greater global participation. The decision will ultimately be made by the FIFA Council, which has the authority to approve changes to the tournament format. As of early 2025, no formal proposal has been submitted, and FIFA has not indicated when a decision might be made. The prediction market reflects uncertainty about whether this expansion will materialize, with odds fluctuating based on statements from FIFA officials and reports from football media.

Historical Context

The FIFA World Cup has undergone several format changes since its inception in 1930. The first tournament featured 13 teams, selected by invitation rather than qualification. From 1934 to 1938, the tournament expanded to 16 teams, a format that remained largely stable through 1978, with exceptions in 1950 (13 teams) and 1974 (16 teams). The 1982 World Cup in Spain was the first to feature 24 teams, a change driven by FIFA's desire to include more nations from Africa and Asia. This format lasted through 1994. In 1998, FIFA expanded to 32 teams, which became the standard for seven tournaments through 2022. The expansion from 24 to 32 was justified by the growing global popularity of football and the need to give more countries a chance to participate. The 2026 World Cup, hosted by the United States, Canada, and Mexico, will be the first to feature 48 teams, a decision made by the FIFA Council in 2017. This expansion was controversial, with critics arguing it would dilute competition quality. The 48-team format will involve 16 groups of three teams, with the top two from each group advancing to a 32-team knockout stage. The 2030 World Cup was originally awarded to Uruguay, Argentina, and Paraguay as a centenary celebration, but was later expanded to include Morocco, Portugal, and Spain as primary hosts. This multi-continent hosting arrangement is unprecedented. The idea of a 64-team tournament was first suggested in 2023 by Ignacio Alonso, who proposed that all 211 FIFA members could participate in the centenary edition. This would require a fundamentally different tournament structure, potentially including a preliminary group stage followed by a main competition. No formal proposal has been presented to the FIFA Council, and the timeline for a decision remains unclear. The 2030 tournament is also notable for being the first to be hosted on three continents, which has already raised logistical questions about travel and scheduling.
