iHeartRadio Music Festival 2026 Lands BTS, Cardi B and Lainey Wilson in Las Vegas

iHeartRadio has set its biggest annual stage for another genre-spanning weekend. On June 2, organisers unveiled the 2026 lineup for the iHeartRadio Music Festival, returning to T-Mobile Arena in Las Vegas across two nights on September 18-19, 2026.

Topping the bill are three headliners pulled from different corners of the charts: K-pop juggernaut BTS, rap heavyweight Cardi B and country star Lainey Wilson. It is a deliberately broad pitch, and the supporting cast reinforces it.

The announced roster so far includes Benson Boone, Zara Larsson, Goo Goo Dolls, Kenny Chesney, Major Lazer, Muse, Snoop Dogg and Weezer, with organisers promising more names to come. Pop, rock, country, hip-hop and dance all share the same two stages, which is the festival's long-running formula and a useful reminder of how versatile a single arena weekend can be.

Ryan Seacrest returns as host. For the trade, the more interesting line in the announcement is the distribution play: performances will stream on Disney+ and Hulu, extending the live event well beyond the roughly 20,000 seats inside T-Mobile Arena and folding a major music property into the same streaming ecosystem that increasingly carries live sport and tentpole events.

On the commercial side, general public tickets go on sale June 12 at 2 p.m. ET via AXS, preceded by a Capital One cardholder presale starting June 10 — a textbook payment-partner presale window of the kind now standard across major US live events.

For anyone working in festivals, sponsorship or live production, the 2026 edition is a clean case study in the modern arena festival: a cross-genre headline strategy, a banking sponsor controlling early access, and a streaming distribution deal turning two nights in Vegas into a national broadcast moment.
