The final weekend of Summer 2025 will feature one of the season’s biggest music events, iHeartRadio Music Festival, presented by Capital One, Sept. 19-20. Hosted by Ryan Seacrest, the two-day event at T-Mobile Arena will feature performances from Bailey Zimmerman, Bryan Adams, Ed Sheeran, Jelly Roll, John Fogerty, LL COOL J, Mariah Carey, Maroon 5, Tim McGraw, and more.

iHeart revealed the roster of celebrity presenters and attendees, which includes Ashlee Simpson, Danielle Fishel, Jana Kramer, Lele Pons, Kyle MacLachlan, Runaway June, Shenseea, and members of international boy band JO1.

As in past years, the festival will extend well beyond the arena. The “House of Music,” presented by Hyundai, will offer a free immersive fan experience across 12 interactive rooms outside the venue. Julia Michaels will perform there ahead of Saturday’s main stage show.

For listeners nationwide, the 2025 iHeartRadio Music Festival will broadcast live across more than 150 iHeartMedia stations each night. Hulu returns as the exclusive streaming partner, carrying the live performances for all subscribers. A special highlights package will debut on the platform Oct. 2.

Corporate partners for this year’s festival include Capital One, Arm & Hammer, Audible, belVita, Hyundai, Impossible Foods, Lenovo Legion, M&M’s, Paris Baguette, and STK Steakhouse. The event is executive-produced by iHeartMedia’s John Sykes, Tom Poleman, and Bart Peters, along with DPS.
