I.O.I is officially gearing up for a long-awaited reunion, as ticket sales for their 10th anniversary concert are set to open, sparking expectations of an intense “ticket war” among fans. Tickets for the Seoul leg of the “2026 I.O.I Concert Tour: LOOP” will go on sale on March 26 at 8 PM via an online ticketing platform.
Given the group’s massive popularity and the rarity of this reunion, competition for seats is expected to be fierce. The concert marks the group’s first full-stage reunion in approximately nine years since their last concert in 2017.
The upcoming performances celebrate I.O.I’s 10th debut anniversary, bringing together members Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kim Doyeon, and Jeon Somi. For both fans and members, the concert represents more than just a performance: it is a reunion of shared memories after years of pursuing individual careers.

The tour will kick off in Seoul at Jamsil Indoor Stadium from May 29 to 31, before continuing to Bangkok on June 6 and Hong Kong on June 20 and 21. The concert’s title, “LOOP,” symbolizes reconnection and continuity, reflecting how the group’s story, though seemingly concluded, has come full circle. Organizers emphasized that the concert is not merely about revisiting the past but about creating a new shared experience between I.O.I and their fans.
Alongside the tour, the group is also preparing a new album as part of their anniversary projects, further heightening anticipation for their comeback. With nearly a decade since their last full-group stage, the upcoming concerts are expected to be one of the most emotional and competitive events in K-pop this year.
