The FIFA World Cup, the largest edition in the tournament’s history, officially begins today as 48 national teams start their quest for football’s most coveted trophy across the United States, Canada and Mexico.

According to Associated Press reports, the opening day marks the start of a 39-day global football spectacle featuring 104 matches played across 16 stadiums in 16 cities, stretching from Mexico City to Vancouver and New York to Los Angeles.

The tournament is being staged for the first time across three countries, with Mexico hosting the opening match, Canada joining the schedule on the following day, and the United States hosting its first fixture shortly after.

FIFA has described the 2026 edition as a “new era” for the World Cup, expanding the format from 32 to 48 teams. The new structure allows more nations than ever before to participate, with teams divided into 12 groups. The top two teams from each group, along with the best third-placed sides, will advance to the knockout stage.

Opening-day matches are expected to draw global attention, with host nation Mexico taking the spotlight amid a festive ceremony in Mexico City. AP reports highlight that veteran players and emerging talents alike will feature in the opening fixtures, including teams returning after long absences and several World Cup debutants.

Security has been tightened across all three host nations, with authorities deploying large-scale operations to manage crowds, fan zones and international visitors expected to arrive in record numbers.

The final will be played on July 19 at MetLife Stadium in New Jersey, marking the culmination of the biggest World Cup ever staged.

FIFA officials say the expanded tournament is designed to bring the World Cup to a wider global audience, while boosting participation from emerging football nations.

With the opening whistle today, the world’s most-watched sporting event begins a new chapter in football history.
