The 2026 World Cup ends July 19. The 6-to-18 months after it — the Legacy Leadership Window™ — will determine whether the tournament was a spectacle or a platform. Across legacy organizations, Liga MX professionalization, sponsor activation transitions, and venue leadership, Mexico's post-World Cup talent market will be one of the most important executive search moments in Latin American sports. A renovated stadium is not a business model. The leaders placed in the window will decide what comes next.
