iHeartRadio Music Festival 2026: Night 1 Sets Up Night 2 in Las Vegas
The iHeartRadio Music Festival 2026 has taken over Las Vegas for a two-night event, with Night 1 bringing BTS, Cardi B, Weezer and other major acts to T-Mobile Arena on Friday, September 18. Attention now turns to Night 2 on Saturday, September 19, which features another lineup of major pop, rock, hip-hop and country performers.
The festival is being held at T-Mobile Arena and is hosted by Ryan Seacrest. The event is presented by Capital One and is being streamed through Disney+ and Hulu, while iHeartMedia radio stations are carrying the festival across more than 150 U.S. markets.
What happened on iHeartRadio Music Festival Night 1?
Night 1 was scheduled for Friday, September 18, with BTS, Cardi B, Goo Goo Dolls, Kenny Chesney, Weezer and Zara Larsson on the bill. T-Mobile Arena lists those six performers specifically under the festival’s Friday billing.
The show began at 7:30 p.m. Pacific Time, following 6:30 p.m. doors at the Las Vegas venue. The official broadcast also began at 7:30 p.m. PT, or 10:30 p.m. ET.
BTS is one of the biggest reasons the festival is drawing attention this year. The group’s appearance comes during its major 2026 return to group activities following its members’ periods of mandatory military service and individual projects.
Cardi B also arrived at the festival during a major period in her career. iHeartRadio highlighted her ongoing new-music plans ahead of the event, adding another reason fans were watching her appearance closely.
However, detailed Night 1 setlists and a complete official post-show recap were not yet available in the latest reliable sources reviewed for this article. That means reports claiming specific surprise appearances, songs or collaborations should be treated cautiously until they are confirmed.
Night 2 lineup: Who is performing?
The second night takes place Saturday, September 19, at T-Mobile Arena.
According to the venue’s official billing, Night 2 features:
- Benson Boone
- Ciara
- Lainey Wilson
- LE SSERAFIM
- Major Lazer
- Muse
- Snoop Dogg
- Stella Lefty
- The Smashing Pumpkins
The lineup is subject to change, according to T-Mobile Arena.
The second night therefore shifts the festival’s musical mix again, moving between pop, country, hip-hop, K-pop, electronic music and rock.
When does Night 2 start?
Saturday’s main festival show is scheduled to begin at 7:30 p.m. PT on September 19, with doors opening at 6:30 p.m. at T-Mobile Arena.
For viewers on the U.S. East Coast, the live broadcast starts at 10:30 p.m. ET.
Fans can watch the performances through Disney+ and Hulu, while iHeartMedia is broadcasting the event through radio stations in more than 150 markets nationwide.
The House of Music is also returning
The festival isn’t limited to the arena.
The iHeartRadio House of Music presented by Hyundai is operating outside T-Mobile Arena from 4 p.m. to 1 a.m. PT on September 18 and 19. The experience includes interactive rooms inspired by artists including BTS, Cardi B, Kenny Chesney and Zara Larsson.
On Saturday, Stella Lefty is scheduled for a pre-show performance at the House of Music, while Major Lazer is scheduled to close the experience with a post-show performance.
Why is the iHeartRadio Music Festival trending now?
The timing is the main reason.
The festival moved from its buildup phase into its live two-night event on September 18, putting several of the year’s biggest music names on the same Las Vegas stage.
BTS’s participation has added particular interest because the group remains one of the world’s most closely followed music acts following its 2026 return. Cardi B, Zara Larsson and the other Night 1 performers have also brought separate fanbases into the conversation.
Now the attention is shifting to Night 2, with Benson Boone, Ciara, Lainey Wilson, LE SSERAFIM, Major Lazer, Muse, Snoop Dogg and The Smashing Pumpkins still scheduled to perform.
What fans need to know for Night 2
The most important confirmed details are straightforward: Night 2 is scheduled for Saturday, September 19, at T-Mobile Arena in Las Vegas, with the main show beginning at 7:30 p.m. PT.
Disney+ and Hulu are the official streaming destinations, while iHeartRadio’s network of radio stations will carry the festival nationwide.
Fans should also remember that the published artist billing is not necessarily a detailed performance order. T-Mobile Arena specifically notes that the lineup is subject to change.
For viewers following individual artists, watching from the beginning is therefore the safest option rather than relying on an unconfirmed stage time.
The 2026 iHeartRadio Music Festival is now moving into its second and final night, with another large mix of artists scheduled to take the T-Mobile Arena stage Saturday.
