Lollapalooza 2026 concluded in Chicago's Grant Park on Sunday night with BLACKPINK's Jennie as a closing headliner. The festival drew record digital viewership on its official Hulu livestream, according to organisers.

The four-day event, produced by C3 Presents, featured Jennie, the rookie group CORTIS, and British singer Olivia Dean across multiple stages. Hulu offered both free and subscriber access to the streams throughout the weekend.

Jennie's solo headline appearance marked one of the highest-profile K-pop sets in the festival's history and generated significant social media engagement. CORTIS drew strong coverage from their early-slot performance, while Olivia Dean's set contributed to a diverse lineup spanning pop, rock and hip-hop.

C3 Presents and Hulu planned to release viewership and attendance figures in the coming days. Entertainment outlets in the United States, South Korea and India tracked the festival's reception.

Grant Park hosted approximately 400,000 attendees across the four days, consistent with recent editions. The festival's conclusion sets the stage for autumn touring announcements from several headline acts.
