Ryan Seacrest returns as host. As in past years, the festival will feature one-of-a-kind collaborations and surprise performances that exist nowhere else — the pairings that tend to become the clips everyone sends each other the next morning.

What the new additions bring to the bill

Ciara arrives with one of the deepest catalogs in modern R&B and pop. Two decades after “Goodies” and “1, 2 Step” made her a fixture of mid-2000s radio, she has remained a reliable hitmaker and one of the most physically commanding performers working — the kind of set that plays as well from the upper bowl as it does from the floor.

The Smashing Pumpkins bring the alt-rock end of the spectrum. Billy Corgan's band defined a particular strain of 1990s ambition — “1979,” “Today,” “Tonight, Tonight,” “Bullet with Butterfly Wings” — and their catalog has found a second life with listeners who weren't born when Mellon Collie and the Infinite Sadness came out.

Stella Lefty, making a special performance, is the newest name on the bill and the fastest-rising. The Illinois-born, Los Angeles-based singer-songwriter broke through in early 2026 with “Boston,” a genre-blurring single that racked up tens of millions of streams and put her on the Billboard Hot 100. Her debut album, Long Way Home, is on the way. For a lot of fans in the arena, this will be the first time seeing her live.

Together with acts like BTS, Kenny Chesney, Muse and Snoop Dogg, the lineup spans K-pop, country, hip-hop, alt-rock, dance and pop — which has always been the point of this particular festival.
