Official Timing and Platform Details
The release timing has been consistent across official and entertainment sources. BELIFT LAB’s Weverse notice gave the key timing in KST, ET and PT, while the HYBE LABELS video description also listed June 12 at 1 p.m. KST and June 12 at 12 a.m. ET, with June 11 at 9 p.m. PT for the U.S. West Coast. 2
The project has been framed by the involved labels as a summer-focused collaboration. In Korean press materials cited by bnt news, BELIFT LAB, SOURCE MUSIC and HYBE-Geffen Records described it as “a project prepared to give global fans special enjoyment this summer.” 5
The available source material does not list production credits, a full tracklist beyond the title song, or separate artist-by-artist line distribution. It confirms the title, participating groups, release timing, official video publication and first-stage schedule.
Why the Collaboration Is Notable
The significance of the release lies mainly in its grouping. LE SSERAFIM, ILLIT and KATSEYE operate as separate girl groups under the wider HYBE ecosystem, and the source-backed reports present “ICONIC BY MISTAKE” as a joint single rather than a festival-only stage or one-off video appearance. Billboard Philippines characterized the release as the first collaboration among the three groups. 4
Starnews reported that HYBE’s three girl groups unexpectedly released the joint music video at midnight on June 11, ahead of the official single timing on June 12 at 1 p.m. 6 That sequencing made the video the first major public piece of the collaboration, followed by the M Countdown stage and then the digital release window.
Because the official video arrived before the single’s listed digital release time, readers may encounter the project in different forms depending on platform and time zone. In Korea, the MV and broadcast stage were tied to June 11, while the formal digital single timing was set for the afternoon of June 12 KST. In North America, the timing translated to late June 11 on the U.S. West Coast and midnight June 12 on the U.S. East Coast. 1
