I.O.I 10th Anniversary Concert: Seoul Dates, Tickets, Tour Plans, and Album Link

I.O.I’s 10th anniversary concert is now taking shape as the clearest centerpiece of the group’s 2026 return. The Seoul run of the 2026 I.O.I Concert Tour: LOOP in SEOUL is scheduled for May 29 to 31, 2026, at Jamsil Indoor Stadium, making it the first concert stop after the release of the group’s third mini album, I.O.I : LOOP.¹

For fans who have followed I.O.I from the Produce 101 era through years of reunion hopes, this IOI Reunion is not just about one weekend of performances. It is being framed around a full comeback cycle: a pre-release track on May 4, the album release on May 19, and then the opening Seoul concerts at the end of May.²

I.O.I 10th Anniversary Concert in Seoul: Key Details

The Seoul concert schedule is compact but meaningful. NOL Ticket lists three performances across three consecutive days: May 29 at 8 p.m., May 30 at 6 p.m., and May 31 at 5 p.m. All three shows are set for Jamsil Indoor Stadium, a familiar large-scale venue for major K-pop concerts in Seoul.¹

Ticketing for the Seoul shows opened on March 26, 2026, at 8 p.m., with a purchase limit of two tickets per person per performance. Prices are listed as 165,000 won for R seats and 154,000 won for S seats.¹ For anyone trying to understand the event at a glance, the details are simple enough, but the emotional weight is much bigger than the table suggests.

Swing Entertainment described the concert as more than a simple reunion, saying it will be “a special occasion where fans and I.O.I look back on the past 10 years and build new memories.”² That quote neatly explains why the concert is the natural focus of this comeback. It is not only a performance schedule; it is a public meeting point between the group’s original story and its next chapter.

How the LOOP Album Connects to the Concert Tour

The concert comes directly after I.O.I’s third mini album, I.O.I : LOOP, which is scheduled for release on May 19, 2026. A pre-release track and YouTube live event are planned for May 4, ahead of the album launch.² StarNews also reported that the album will arrive at 6 p.m. on May 19, with the pre-release song coming first on May 4.³

The title LOOP feels especially fitting for this project because the comeback has been described around ideas of reunion and return. The group was formed through Produce 101 in 2016, and the new release is described as I.O.I’s first new album in nine years.³ That long gap is part of what makes the concert feel like a 10th anniversary event in spirit as much as in branding.

The tracklist for I.O.I : LOOP was revealed through the group’s official social media on April 27, 2026. Reports identify the title track as 갑자기, while other listed songs include IOI (Where My Girls At), IF I, 그때 우리 지금, SPF 100+ (Summer Pop Fantasy), and 웃으며 안녕.⁴⁵ Jeon Somi participated in writing the lyrics for the title track, adding another personal layer to the comeback material.⁵

The participating lineup for this activity includes Im Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kim Doyeon, and Jeon Somi.⁵ With nine members named for the comeback activity, the concert will likely be watched closely by fans who want to see how the new songs and the group’s history are presented together on stage. The available sources do not provide a concert setlist, so it is best to treat the album tracklist as confirmed album information, not as a confirmed performance order.

Seoul Opens a Wider Asia Tour

The Seoul concerts are also the starting point for a broader tour plan. After the May 29-31 run in Seoul, the tour is expected to continue to major Asian cities including Bangkok and Hong Kong.² One confirmed overseas stop is 2026 I.O.I Concert Tour: LOOP in BANGKOK, scheduled for June 6, 2026, at 6 p.m. at IDEA LIVE, BRAVO BKK.⁶

IME Thailand lists Bangkok ticket prices from 2,900 to 6,800 baht, with both IME presale and general ticketing scheduled for May 2, 2026.⁶ That makes Bangkok the clearest international date currently supported by the provided source material, while Hong Kong is named as part of the wider Asia tour plan without a detailed venue or date in the available records.

When is the I.O.I 10th anniversary concert in Seoul?

The Seoul concerts are scheduled for May 29, May 30, and May 31, 2026. The listed start times are 8 p.m. on May 29, 6 p.m. on May 30, and 5 p.m. on May 31.¹

Where will the Seoul concert be held?

The 2026 I.O.I Concert Tour: LOOP in SEOUL will be held at Jamsil Indoor Stadium in Seoul.¹

Is the concert connected to a new I.O.I album?

Yes. The concerts follow the scheduled May 19, 2026 release of I.O.I’s third mini album, I.O.I : LOOP. A pre-release track is scheduled for May 4, 2026.²

For longtime fans, the I.O.I 10th anniversary concert is the most concrete expression of the group’s return: three Seoul performances, a new mini album, and an Asia tour beginning to unfold. With I.O.I : LOOP arriving before the Seoul shows, the reunion is being built as both a look back and a new performance era, ending one long wait with a clear date on the calendar.
