Stray Kids Make History as Rock in Rio's First K-Pop Headliner: 100,000 Fans in 2026

Stray Kids closed the Palco Mundo main stage at Rock in Rio 2026 on the night of September 11–12, becoming the first K-pop act in the festival's 40-year history to headline the event before an audience of approximately 100,000 at Olympic Park in Rio de Janeiro. The eight-member JYP Entertainment group played a 15-song set that opened with 'DIVINE' and ended with a Portuguese-language cover of Michel Teló's 'Ai se eu te pego' — a moment engineered as a direct handshake with the Brazilian crowd and one that landed as the evening's most viscerally received sequence.

The set drew from across Stray Kids' discography: 'DIVINE,' 'Do It,' 'Bounce Back,' 'Walkin on Water,' 'DOMINO,' 'Thunderous,' 'MIROH,' 'Side Effects,' 'God's Menu,' 'CEREMONY,' 'MANIAC,' 'ROCK-STAR,' 'LALALALA,' 'Social Path,' and the Teló cover. The sequence moved from their newest material — 'DIVINE' and 'Do It' are from the August 2026 mini album 'THIS & THAT' — through the commercial anchor tracks 'God's Menu,' 'MANIAC,' and 'ROCK-STAR' that defined their Billboard 200 run, into the fan-favourite deep catalogue of 'MIROH' and 'Thunderous.' 'Walkin on Water,' an English-language track built for festival audiences, held the middle section.

The Teló cover was the structural centrepiece. 'Ai se eu te pego' is one of the most culturally embedded festival songs in Brazilian pop history, and Stray Kids' decision to perform it — in Portuguese — as the set's emotional peak read as preparation rather than improvisation. STAY in the Rio crowd sang back every word, and the moment circulated widely on social media in the hours after the set ended. It is the kind of performance gesture that distinguishes a group that studied the room from one that simply showed up to it.

Rock in Rio was founded in 1985 and has hosted Queen, Iron Maiden, Guns N' Roses, Beyoncé, Lady Gaga, and Coldplay on its main stage. Stray Kids' headliner slot — confirmed by the festival in November 2025 — is not merely a demographic signal about K-pop's Western audience growth; it is a booking decision made by a festival that does not extend its headline slot to acts that cannot hold 100,000 people. The crowd size and the set's reception confirmed the booking was correct: Stray Kids held the Palco Mundo from midnight through 1:45 AM local time without a perceptible energy drop.

The Rock in Rio slot arrived five weeks after 'THIS & THAT' debuted at No. 1 on the Billboard 200 — Stray Kids' ninth consecutive chart-topper, a record unmatched in the chart's modern era and equivalent to The Rolling Stones' all-time tally among groups. The two milestones in the same month — chart history and festival history — represent Stray Kids at the peak of their commercial and live power simultaneously.

Stray Kids were not the only Korean act on the Palco Mundo bill. Hwasa performed earlier on the same stage on September 11, becoming the first K-pop female solo artist to appear on Rock in Rio's main stage before a crowd of approximately 80,000. Her 13-song, one-hour set — drawing on 'Maria,' 'Twit,' and 'Good Goodbye' alongside newer solo material — established her as the second major K-pop landmark of the same festival day. NEXZ, the JYP junior boy group and Stray Kids' tour labelmates, also appeared. The full Rock in Rio 2026 lineup placed Stray Kids alongside Calvin Harris, Black Eyed Peas, Maroon 5, and Elton John — an association that frames K-pop not as a supporting novelty but as a peer headliner in one of the world's most watched live music events.
