IOI Unveils ‘LOOP’ Concert Poster, Signaling a Radiant 10th Anniversary Reunion

I.O.I has officially revealed the main poster for their 10th anniversary concert project, igniting excitement for a long-awaited reunion moment under the title 2026 I.O.I Concert Tour: LOOP.

Posted at midnight on the 29th via their official social media channels, the Seoul concert poster radiates bright, refreshing energy—capturing the emotional impact of members meeting again after nine years. The image highlights their matured visuals while preserving the vibrant, youthful spirit that defined their original rise, creating a nostalgic yet evolved atmosphere.

The visual composition emphasizes unity, with the members’ distinct personalities blending into a seamless synergy that reflects their enduring bond. The looping “LOOP” logo flows dynamically across the design, paired with a 10th-anniversary symbol that reinforces the meaning of return, continuity, and shared history.

Rather than simply revisiting the past, the LOOP project is positioned as a moment where individual journeys and fan memories intersect—transforming nostalgia into connection and growth into celebration.

The tour will begin in Seoul at Jamsil Indoor Stadium from May 29 to 31, before expanding across Asia, including stops in Bangkok and Hong Kong, marking a global celebration of their decade-long journey.

Ahead of the tour, I.O.I will release their third mini-album IOI : LOOP on May 19, featuring deeper musical involvement from the members in songwriting. A pre-release track dropping on May 4 will further build anticipation for their long-awaited comeback era.
