iHeartRadio Music Festival 2026 Las Vegas: Full Lineup at T-Mobile Arena

September just became the most important month on the Las Vegas entertainment calendar. The iHeartRadio Music Festival is back, the lineup is stacked, and two names in particular are going to bring a wave of fans to this city unlike anything we have seen in recent memory.

The Event

The 2026 iHeartRadio Music Festival presented by Capital One takes over T-Mobile Arena on September 18 and 19. Ryan Seacrest hosts both nights. Every performance streams live on Disney Plus and across iHeartRadio platforms, which means the Las Vegas audience gets the show and the world watches along.

Why This Festival Matters for Las Vegas

The iHeartRadio Music Festival is one of the most-watched live music events in the country. Holding it in Las Vegas is not coincidental. This city has the infrastructure, the venues, and the audience to host events of this scale better than anywhere else on earth. T-Mobile Arena is one of the finest live music venues in the world, and September in Las Vegas is prime time.
