The 2026 FIFA World Cup has shattered attendance records, surpassing 5 million spectators as of the Round of 16, with 27 matches still to be played. On June 25, the tournament officially broke the all-time attendance record for a single World Cup with 3,605,357 fans, exceeding the previous record of 3,587,538 set at the 1994 World Cup, also held in the United States. This record was broken during Ecuador's 2-1 win over Germany at MetLife Stadium.

FIFA announced that as of June 25, the tournament had already drawn over 3.8 million fans through 60 matches, achieving an impressive 99.7% stadium occupancy rate. The highest single-day attendance record in World Cup history was also set on June 25, with 426,834 spectators attending matches across the three host nations. The substantial increase in attendance is primarily attributed to the tournament's expansion to 48 teams and 104 total games, which is 40 more than the 2022 World Cup.

The 2026 World Cup is projected to reach a total attendance of 6.7 million based on current averages. The tournament benefits from larger venues in the United States, Canada, and Mexico, with an average stadium capacity of 69,134, a 42% increase compared to the 1998-2022 average. While the overall attendance has set records, the average attendance per match in 2026 is currently 64,720, slightly lower than the 1994 World Cup's average of 68,991, which had fewer matches and teams but larger average stadium capacities of 74,166 across its nine venues. Prominent stadiums this year include MetLife Stadium and AT&T Stadium (also known as "Jerry World"), the largest with a stated capacity of 92,967.

FIFA President Gianni Infantino has praised the tournament's success, highlighting the full stadiums and the positive atmosphere, noting the presence of many families, children, and women. He believes the 2026 World Cup could become the first to reach 7 million spectators. The new attendance record highlights football's unique ability to unite people globally, according to Infantino.
