LE SSERAFIM Makes History at the 2026 iHeartRadio Music Festival

LE SSERAFIM is continuing its powerful global rise. The K-pop girl group has officially joined the lineup for the 2026 iHeartRadio Music Festival, one of the biggest annual music events in the United States.

The festival will take place at T-Mobile Arena in Las Vegas on September 18 and 19, 2026. LE SSERAFIM is scheduled to perform on the second day of the festival, joining a star-studded lineup that includes global artists such as BTS, Cardi B, Snoop Dogg, Benson Boone, Muse, Major Lazer, Weezer, Zara Larsson, Lainey Wilson, Kenny Chesney, and Goo Goo Dolls.

This appearance is especially meaningful because LE SSERAFIM is reported to be the first K-pop girl group to perform at the iHeartRadio Music Festival. For FEARNOTs around the world, it marks another major milestone in the group’s journey from a powerful K-pop act to a global festival name.

What Is the iHeartRadio Music Festival?

The iHeartRadio Music Festival is one of the most recognized live music events in the U.S. Every year, it brings together some of the biggest names in pop, rock, hip-hop, country, and global music.

The 2026 festival will be hosted by Ryan Seacrest and broadcast across iHeartMedia’s radio network. Fans who cannot attend in person will also be able to watch the event through Disney+ and Hulu, making the performance accessible to a wider global audience.

For K-pop artists, being included in this kind of mainstream U.S. festival lineup is a major signal of international recognition. LE SSERAFIM’s appearance shows how strongly K-pop continues to expand across global music markets.

LE SSERAFIM’s Growing Global Presence

LE SSERAFIM has steadily built a reputation for intense performances, bold concepts, and confident music. Known for songs such as “FEARLESS,” “ANTIFRAGILE,” “UNFORGIVEN,” “CRAZY,” and “SPAGHETTI,” the group has continued to attract international attention with every release.

Their upcoming iHeartRadio Music Festival appearance is not an isolated moment. In 2026, LE SSERAFIM is also set to return to BlizzCon 2026 as the closing musical act on September 13. The group previously performed at BlizzCon in 2023, becoming one of the first K-pop acts to appear at the global gaming festival.

Around the same period, LE SSERAFIM will also begin its North American tour, starting in Los Angeles before visiting multiple cities across the region. With major festival appearances, live broadcasts, and a growing international tour schedule, 2026 is shaping up to be one of the group’s most important global years.

Why This Moment Matters for K-pop Fans

LE SSERAFIM’s iHeartRadio Music Festival stage is more than just another performance. It represents the growing influence of K-pop girl groups in the global entertainment industry.

For many years, K-pop has expanded through albums, music videos, fan communities, and world tours. Now, K-pop artists are increasingly appearing on major Western festival stages and mainstream entertainment platforms. LE SSERAFIM’s participation in the iHeartRadio Music Festival reflects that shift.

For FEARNOTs, this is also a moment of pride. Seeing LE SSERAFIM perform alongside some of the biggest names in global music highlights how far the group has come since debut. Their strong stage presence, sharp choreography, and fearless identity make them a perfect fit for a high-energy festival environment.
