K-pop groups LE SSERAFIM, ILLIT, and KATSEYE have announced a collaborative single titled "ICONIC BY MISTAKE" [1].
This partnership marks a rare joint venture between three distinct musical acts, signaling a strategic effort to merge their respective fanbases through a single high-profile release [1, 3].
The collaboration was officially announced June 8, 2026, at 00:00 KST [1]. According to the promotion schedule, the official single is set to release June 12, 2026, at 13:00 KST [3].
Fans will see the official music video before the song's full release. The video is scheduled for pre-release June 11, 2026, at 00:00 KST [3]. This visual rollout is designed to build momentum leading up to the track's official debut.
In addition to the digital release, the groups will appear together for a live performance. This event is scheduled for June 11, 2026, on the South Korean music program M Countdown [3].
The project involves a total of three groups [1]. By combining the talent of LE SSERAFIM, ILLIT, and KATSEYE, the release aims to maximize global reach across different markets, spanning from the established K-pop scene to the international appeal of KATSEYE.
The official music video will be hosted on YouTube, providing a central hub for the global audience to access the collaboration [4].
“The three groups will release 'ICONIC BY MISTAKE' with a music video and live performance scheduled for this week.”
The collaboration between LE SSERAFIM, ILLIT and KATSEYE represents a significant cross-promotional strategy within the HYBE ecosystem. By grouping an established act, a newer group, and a global group together, the label can effectively transfer listeners between these different demographics, strengthening the market position of the newer groups while maintaining the visibility of the veterans.
