I.O.I is gearing up for a highly anticipated 10th anniversary reunion with the “2026 I.O.I Concert Tour: LOOP.” Tickets for the Seoul leg of the tour go on sale March 26 at 8 PM, and fans are expected to compete fiercely for seats due to the group’s lasting popularity and the rarity of this full-group reunion. This will be the first time the nine members perform together on stage since 2017, nearly nine years after their last concert.

The tour brings together Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kim Doyeon, and Jeon Somi. For the members and fans, the reunion is more than just a performance. The title “LOOP” symbolizes reconnection and continuity, emphasizing that the event is about creating new experiences together rather than only celebrating past achievements.
