The 2026 iHeartRadio Music Festival takes place on September 18 and 19 at T-Mobile Arena in Las Vegas, with a live stream on both nights. According to the official iHeartRadio viewing guide, the broadcast starts at 7:30 p.m. Pacific Time, which is 10:30 p.m. Eastern Time. For viewers using Brasilia time, the start is 11:30 p.m. each night.
For video viewing, iHeartRadio confirms Disney+ and Hulu as the official livestream destinations, with all performances available to subscribers. Disney's September programming also lists the event on Disney+ and Hulu on September 18 and 19. The key point for anyone outside the United States is to check availability inside the app, because catalogs and live events can vary by territory.
What time does the 2026 iHeartRadio Music Festival start?
The official start time for Friday and Saturday is 7:30 p.m. PT and 10:30 p.m. ET. Because the festival is held in Las Vegas, its local time is Pacific Time. The table below converts the start of both nights for several useful time zones.
| Location / time zone | September 18 night | September 19 night |
|---|---|---|
| Las Vegas, PT | 7:30 p.m. on Sep. 18 | 7:30 p.m. on Sep. 19 |
| New York, ET | 10:30 p.m. on Sep. 18 | 10:30 p.m. on Sep. 19 |
| Mexico City | 8:30 p.m. on Sep. 18 | 8:30 p.m. on Sep. 19 |
| Brasilia | 11:30 p.m. on Sep. 18 | 11:30 p.m. on Sep. 19 |
| London | 3:30 a.m. on Sep. 19 | 3:30 a.m. on Sep. 20 |
| Madrid | 4:30 a.m. on Sep. 19 | 4:30 a.m. on Sep. 20 |
These conversions use the time zones in effect on the festival dates. Viewers elsewhere should compare their local time with 7:30 p.m. in Las Vegas.
Where to watch live: Disney+ and Hulu
iHeartRadio says Disney+ and Hulu will livestream every performance on both nights. On Disney+, the official event page already identifies Night 1 as a live stream, and the Disney+ Help Center includes the iHeartRadio Festival among its 2026 festivals available on September 18 and 19.
For Disney+, the official requirement is straightforward: you need an active subscription and a supported device. The Help Center also says ads may play between performances regardless of your plan. That means an ad-free plan should not be interpreted as a guarantee of a completely commercial-free live event.
For Hulu, iHeartRadio's announcement describes access for subscribers and does not state that a Hulu + Live TV package is required. There is therefore no official basis in that festival announcement for saying the Live TV tier is mandatory just to watch the event. Final availability should still be checked in the subscriber's account and device.
Hulu is a U.S. service; Disney+ availability varies by territory
Market availability matters. The Disney, ESPN and Hulu Subscriber Agreement, updated in 2026, states that the Hulu service is available only in the United States and certain U.S. territories. Viewers outside that market should therefore not rely on Hulu as their access route.
Disney+ operates in more markets, but the same agreement notes that content can vary based on rights, subscription tier and location. In practical terms, the festival's presence on U.S. Disney+ does not automatically guarantee that the same livestream is available in every country. Outside the U.S., the safest check is to open Disney+ in the account's territory and search for iHeartRadio Music Festival 2026 close to the broadcast time.
There is also an official Disney+ page for Night 1, which helps confirm distribution through the service, but actual access remains subject to territory and account profile settings.
You can also listen through iHeartRadio
Viewers who do not need video have an official alternative. iHeartRadio says the festival will be broadcast live across its radio stations in more than 150 U.S. markets. The network also directs listeners to its digital listening options, which can be useful when the video stream is not available in a user's territory.
Which artists are confirmed?
The general lineup announced by iHeartRadio includes Benson Boone, BTS, Cardi B, Ciara, Goo Goo Dolls, Kenny Chesney, Lainey Wilson, LE SSERAFIM, Major Lazer, Muse, Snoop Dogg, The Smashing Pumpkins, Weezer and Zara Larsson, plus a special performance by Stella Lefty. Ryan Seacrest returns as host.
The official guide confirms the weekend lineup, but that page does not provide a complete artist-by-artist timetable. It is better not to treat an unofficial running order as final unless the festival publishes a specific schedule update.
Checklist so you do not miss the start
- Open Disney+ or Hulu early and search for the festival by name.
- Confirm that your subscription is active and your device is supported.
- In the U.S., the start is 7:30 p.m. PT / 10:30 p.m. ET; in Brasilia time, it is 11:30 p.m.
- Outside the U.S., check Disney+ in your territory first, because Hulu is limited to the U.S. and certain territories.
- Expect that ads may appear between performances on Disney+, even on ad-free plans.
- If the event does not appear, check territory restrictions and the profile's content rating before looking for unofficial alternatives.
Streaming details can be updated close to showtime. For the latest confirmation, check the official iHeartRadio guide and the event page inside the streaming service available in your region.
