Eleven NFL stadiums serve as primary venues for 2026 World Cup matches. Each facility underwent substantial modifications to meet international tournament standards and football-specific requirements.

Transformations included field markings, security system upgrades, and infrastructure adaptation from American football specifications to soccer standards. The scope of work reflects the divergent architectural needs between the two sports.

This renovation scale underscores U.S. commitment to World Cup hosting and significant capital investment in venue readiness at global standards. The undertaking ranks among the largest stadium conversion projects in American sports history.
