I.O.I Reunites After 9 Years: K-Pop Group's Surprise Comeback

The group I.O.I will reunite with fans for a full group performance to celebrate their 10th anniversary. This marks the first time all I.O.I members will be on stage together in approximately 9 years, since their concert in 2017. The concert title is '​LOOP', signifying that their paused story will resume and cycle into new encounters.

Ticket sales for the Seoul leg of I.O.I's 10th anniversary concert, '2026 I.O.I Concert Tour: LOOP', will begin on the 26th at 8 PM via the online site NOL. The concert will be held for three days from May 29th to 31st at the Jamsil Indoor Gymnasium in Seoul. Following Seoul, the tour will continue to major Asian cities, including Bangkok on June 6th and Hong Kong on June 20th and 21st.

In addition to the concert, a 10th-anniversary commemorative project will be unveiled sequentially. I.O.I has recently completed jacket photo and music video filming for a new album and is in the final stages of preparation with a comeback targeted for May.

The group I.O.I has announced the upcoming large-scale concert tour 'LOOP' to commemorate their 10th debut anniversary. This concert will be the members' first stage together in a remarkable 9 years since their solo performance in January 2017. The title 'LOOP' embodies the meaning of connection and circulation, implying a message that their story, which seemed to have ended, will resume and usher in a new beginning.

I.O.I member Lim Nayoung announced their impending comeback by posting a photo of all the members gathered on her social media. In the revealed photo, the I.O.I members are seen in what appears to be a practice room, posing affectionately in matching bright pink sweatshirts and black shorts.
