I.O.I Confirms 10th Anniversary Reunion With New Album and Asia Tour

I.O.I (아이오아이) will reunite in May 2026 for their 10th debut anniversary with a new album, a Seoul concert, and an Asia tour, according to SWING Entertainment's official confirmation on February 23. Nine of the original eleven members are participating, making this the most substantial revival attempt since the project group disbanded in January 2017. For fans who have watched reunion rumors collapse more than once, that level of formal detail matters. SWING is not teasing a commemorative livestream or a vague one-off stage. It is outlining a full comeback campaign with centralized management, live dates, and new music. In a generation of K-pop built on temporary survival-show groups, that makes I.O.I's return more than nostalgia. It makes it a real industry event. According to the agency's framing, the reunion is being treated like a proper comeback cycle, not a sentimental afterthought.

On February 23, SWING Entertainment confirmed that nine of the original eleven members will reunite in May 2026 to celebrate the group's 10th debut anniversary, according to the agency's official statement carried widely in Korean entertainment press. A new album and an Asia tour are in the works, with SWING taking full management control of the project. This is not another false start. This is happening.

The Confirmation

SWING Entertainment confirmed on February 23 that I.O.I is preparing a comeback for May 2026 with nine members, a new album, a Seoul concert, and an Asia tour. Korean entertainment outlets including Soompi and domestic wire coverage carried the agency's statement, but the underlying attribution is SWING itself, not a secondary publication. That distinction matters because earlier reunion attempts frequently collapsed in the rumor stage. This time the project arrived with an agency-backed management structure and a defined activity plan.

The returning lineup includes Jeon Somi, Kim Sejeong, Choi Yoojung, Chungha, Kim Sohye, Jung Chaeyeon, Kim Doyeon, Yoo Yeonjung, and Lim Nayoung. Two original members, Kang Mina and Zhou Jieqiong, will not be participating.

Why This Reunion Matters

I.O.I is not just another disbanded group getting back together. They are the prototype that changed how modern survival-show idol groups are built, marketed, and remembered. According to Mnet's original Produce 101 records, the group emerged from a public-voting format that turned audience participation into the core of the debut story itself. That model did more than produce one successful act. It created the commercial blueprint later used by Wanna One, IZ*ONE, and X1, while pushing agencies to treat fan investment as part of the product from day one. When I.O.I reunites, the moment carries more weight than a standard anniversary project because it reconnects the current K-pop landscape to one of the key turning points that helped shape it. That history is why the reunion lands as both a fan-service moment and a market test for legacy project groups.

When Mnet's Produce 101 aired in early 2016, it introduced a concept that would fundamentally change how K-pop groups are formed: let the public vote. One hundred and one trainees from dozens of agencies competed for eleven spots, and the final lineup debuted on May 4, 2016, with the EP Chrysalis, according to Mnet's official records. The format was so successful that it spawned Wanna One, IZ*ONE, and X1, turning survival show debuts into one of K-pop's most reliable commercial models.

But I.O.I only had eight months together. Their contract was temporary by design, and by January 2017 the members had returned to their respective agencies. The Time Slip farewell concert, held January 20 to 22, 2017, marked their final group activity. What followed was nearly a decade of fan campaigns, failed reunion attempts, and industry speculation.

Where They Are Now

The trajectories of I.O.I's members since 2017 tell the story of an entire generation of K-pop talent.

Chungha (청하) built the most successful solo music career of any member. After debuting solo in June 2017 with Hands on Me, she became one of K-pop's defining soloists with hits like "Gotta Go" and "Snapping." Her 2021 album Querencia received international acclaim. She is currently signed with More Vision and 88rising, according to her agency.

Jeon Somi (전소미), the show's first-place winner, left JYP Entertainment and signed with THE BLACK LABEL. Her 2019 debut single "Birthday" and 2021 album XOXO established her as a solo force, with "Fast Forward" becoming her highest-charting single in 2023.

Kim Sejeong (김세정) pivoted into acting and never looked back. After a stint with Jellyfish Entertainment's Gugudan, she landed lead roles in The Uncanny Counter (2020), Business Proposal (2022), and Brewing Love (2024), becoming one of South Korea's most in-demand actresses while maintaining a solo music career.

Jung Chaeyeon (정채연) followed a similar path, earning critical praise for The King's Affection (2021), The Golden Spoon (2022), and Family by Choice (2024) under BH Entertainment.

Choi Yoojung and Kim Doyeon debuted together in Weki Meki under Fantagio, with Yoojung releasing her solo single album Sunflower in 2022. Yoo Yeonjung joined Starship Entertainment's WJSN. Kim Sohye transitioned to acting with roles in Best Chicken (2019) and My Lovely Boxer (2023). Lim Nayoung, the group's former leader, debuted with Pristin under Pledis Entertainment before that group also disbanded in 2019.

The Failed Reunions

This is not the first time an I.O.I reunion has been announced. In 2019, reports emerged of a planned comeback, but the project collapsed due to conflicts between the members' various agencies. A 2021 livestream reunion brought some members together virtually, but Kang Mina was absent and Zhou Jieqiong could only video-call in from China.

What makes 2026 different is the management structure. SWING Entertainment has secured full control of the reunion project, eliminating the multi-agency coordination problems that derailed previous attempts. With one entity managing schedules, creative direction, and logistics, the path from announcement to execution is significantly clearer.

The Missing Members

Kang Mina and Zhou Jieqiong will not join the reunion, according to SWING Entertainment. Kang Mina, who was also absent from the 2021 livestream, has been notably disengaged from I.O.I group activities. Zhou Jieqiong returned to China after I.O.I disbanded and built a career in Chinese entertainment, making participation in a Korean-based reunion logistically difficult.

Nine out of eleven is still a remarkable turnout for a project group that was only active for eight months a decade ago. The fact that members with thriving solo careers, like Chungha and Jeon Somi, are clearing their schedules speaks to the genuine bond between the members and the cultural significance of this reunion.

What to Expect

SWING Entertainment has confirmed a new album, a Seoul concert, and an Asia tour. The May 2026 timeline aligns with the group's original debut month, adding symbolic weight to the anniversary. Specific dates, venue information, and tracklist details have not yet been announced.

For fans who have waited since January 2017, the message is simple: I.O.I is back. For real this time.
