Why is the FIFA World Cup 2026 being held in three countries?

The 2026 World Cup is being held in the United States, Canada, and Mexico, a first in the tournament's history. The three countries joined forces under the slogan 'United As One' and their joint bid won 67% of the votes at the FIFA Congress in 2018. The expansion to 48 teams and 104 matches made it impossible for a single nation to host, especially since existing stadiums already offered an average capacity of over 68,000.
