According to ESPN, the 2026 World Cup has brought 48 teams to the United States, Mexico and Canada for the sport’s largest tournament, and the competition’s fans and traditions have produced countless viral moments captured across social media.
Some of the early highlights include a dramatic late call-up for Argentina defender Marcos Senesi, a moment his girlfriend recorded, and U.S. players watching the New York Knicks’ 29-point NBA Finals comeback together the night before the tournament — a clip that showed midfielder Tyler Adams among the most animated fans, according to ESPN.
Fan culture and off-field antics have fueled other viral clips. Algeria’s base camp in Lawrence, Kansas, has won new supporters in the college town, and Algeria captain Riyad Mahrez has been featured trying other sports. DR Congo arrived looking sharp in their first World Cup in 52 years, earning attention as one of the best-dressed teams, while Shakira performed at the Azteca for the opening ceremony, according to ESPN.
Host-nation enthusiasm has produced memorable scenes. Toronto’s streets were painted red ahead of Canada’s opener, and actor-producer Ryan Reynolds was in attendance for Canada’s first-ever men’s World Cup goal on home soil. High-profile spectators at the U.S. opener included David Beckham, Tom Cruise and Anya Taylor-Joy, ESPN reported.
Scotland’s return to the World Cup generated a standout promotional push, with adidas enlisting Irvine Welsh and Lewis Capaldi for a rallying video set to Iggy Pop that amplified support for the Tartan Army. Other viral moments included Mexico’s duck mascot Merlin, Ecuador fans draping the Rocky statue in Philadelphia ahead of their match, and a Haitian street parade celebrating the country’s first World Cup, per ESPN. Ecuador went on to lose 1-0 to Ivory Coast on Sunday night, according to ESPN.
