On September 11, the K-pop juggernauts closed out the festival’s historic first-ever K-pop-focused day, headlining the iconic Palco Mundo in front of a massive crowd as approximately 130,000 people passed through the Cidade do Rock that day.
From the moment Stray Kids appeared on stage, the crowd erupted as the eight members unleashed their signature combination of explosive choreography, live-band energy and larger-than-life stage presence. Brazilian STAYs had waited for this moment — and they made sure the group knew exactly how much it meant.
The official Stray Kids account captured the emotion afterward, writing:
“What an unforgettable night. Obrigado, STAY!”
The performance was especially significant because Stray Kids made history as the first K-pop act to headline Rock in Rio, one of Brazil’s biggest and most internationally recognized music festivals. (bandwagon.asia)
But this wasn’t simply another festival appearance.
For the first time in its 41-year history, Rock in Rio dedicated an entire day to K-pop, with NEXZ, Hwasa and Stray Kids leading the lineup on Palco Mundo. (UOL)
And Stray Kids were clearly the night’s main event.
Brazilian media reported that fans had already packed the front areas of Palco Mundo hours before the headliners appeared, with the enormous concentration of fans becoming so intense that Rock in Rio staff issued safety warnings asking people near the barriers to step back during the earlier performances.

The scale of the event was equally enormous. Rock in Rio 2026 was designed to accommodate around 100,000 fans per day, with approximately 30,000 workers bringing the total number of people moving through the festival grounds to around 130,000 daily. The Cidade do Rock spans roughly 385,000 square meters, while the newly redesigned Palco Mundo features 2,400 square meters of LED screens and 200 amplifiers. (A Redação)
And Stray Kids proved exactly why they were chosen to make this historic moment happen.
Their performance brought together fans from across Brazil and around the world, transforming Palco Mundo into a sea of lightsticks, screams and synchronized fan chants.
After conquering stadiums and major festivals around the world, Stray Kids’ Rock in Rio appearance marked another major milestone in their explosive global rise — and a powerful statement about just how far K-pop has come.
And the energy was undeniable.
