Post Malone performed a live set before the FIFA World Cup 2026 final, using the pre-match slot to debut his new track 'Chrome Heartbreaker'. The appearance formed part of an elaborate pre-game and half-time entertainment lineup surrounding the Spain-Argentina final, reflecting how major sporting finals increasingly incorporate large-scale musical showcases to draw wider cultural attention.

The performance took place at New York New Jersey Stadium ahead of kick-off, with Post Malone also playing 'Wow' and bringing out Swae Lee for 'Sunflower'. Spain went on to beat Argentina 1-0, securing their second World Cup title in a match echoing their 2010 extra-time win over the Netherlands. Other pre-match acts included Tom Cruise, IShowSpeed, Jennifer Hudson, and Robbie Williams, Laura Pausini and Nicole Scherzinger performing the tournament's first official anthem, while Chris Martin curated a half-time show featuring Madonna, Shakira, BTS and Justin Bieber.
