Post Malone headlined the closing ceremony ahead of the 2026 FIFA World Cup final, delivering a three-song set that included the live debut of a previously unreleased track before Sunday's championship match between Argentina and Spain at MetLife Stadium in East Rutherford, New Jersey. The performance formed part of a star-studded pre-match build-up that FIFA president Gianni Infantino called a "landmark" moment intended to unite fans across the tournament's 48 teams and 16 host cities before attention turned to the finalists.

Wearing his trademark denim and cowboy hat, the 31-year-old opened with a new song believed to be titled "Chrome Heartbreaker" before performing his 2019 hit "Wow." and closing with "Sunflower" alongside guest Swae Lee. Streamer IShowSpeed warmed up the crowd earlier with his song "Champions", while Jennifer Hudson sang the national anthem and Robbie Williams, Nicole Scherzinger and Laura Pausini performed the FIFA anthem "Desire"; Tom Cruise also addressed the stadium. The ceremony began around 1:30pm ET, roughly 90 minutes before kick-off, with an 11-minute halftime show featuring BTS, Justin Bieber, Madonna and Shakira, curated by Coldplay's Chris Martin, still to follow.
