Proponents of a 64-team World Cup argue that the expansion is a necessary step to truly globalize the sport. By increasing the number of participating nations, FIFA can provide a vital incentive for developing football programs in smaller countries that have historically struggled to qualify. Supporters point to the 2026 tournament as evidence that the competitive gap between traditional powerhouses and emerging nations is narrowing, with many teams delivering high-quality performances that have captivated global audiences. This inclusivity is seen as essential for the long-term health and popularity of the game.
From a logistical and structural standpoint, a 64-team format offers a cleaner, more intuitive competition model. The current 48-team system, which relies on complex calculations to determine which third-place teams advance, has been criticized for its lack of clarity. By moving to 16 groups of four, FIFA could return to a standard format where the top two teams from every group move forward. This would not only simplify the experience for fans but also ensure that every match in the group stage carries significant weight, as teams would be competing directly for the top two spots without relying on the performance of other groups.
Furthermore, the 2030 centennial celebration provides a unique opportunity to integrate more host nations into the tournament. An expansion could allow countries like Uruguay, Argentina, and Paraguay to play a more substantial role in the event, hosting full groups rather than just ceremonial opening matches. This would distribute the economic and cultural benefits of hosting more broadly, reinforcing the idea that the World Cup belongs to the entire world rather than just a few established regions.
