YG Entertainment has confirmed plans to introduce a five-member boy group in September, setting up the agency’s first new boy-group debut in six years. The YG new boy group was announced through an official company update on April 30, with Yang Hyun-suk saying the lineup has been finalized at five members.1
The September launch places the new act after Treasure, YG Entertainment’s most recent boy group, which debuted in 2020. Multiple Korean media reports described the plan as a formalized second-half project for the agency, with further rookie-related disclosures expected to follow.2
Five-Member YG New Boy Group Targeted for September Debut

YG LIFE stated that YG Entertainment will officially debut a new five-member boy group in September, calling it the company’s first new boy group in six years.1 The announcement was delivered through a YG video posted on April 30, where Yang Hyun-suk outlined upcoming projects and confirmed the size of the new lineup.
“We’ve finalized the lineup with five members,” Yang said in the official announcement video, as quoted by YG LIFE.1
Yonhap News Agency also reported that YG plans to introduce the new male group around September, citing Yang’s statement that the company is preparing to present a new boy group at that time.2 SBS News likewise reported that YG had formalized a September debut plan for a five-member rookie boy group.3
The group’s name, individual member identities, debut release format, concept, and exact debut date were not included in the source announcements. Based on the available information, the confirmed details are limited to the five-member lineup and the planned September debut window.
The decision to debut a five-member team also gives the group a different structure from Treasure’s original launch. Korea JoongAng Daily noted that Treasure debuted in 2020 as a 12-member act and is now active as a 10-member group.4 The new boy group’s smaller lineup was highlighted across reports as one of the clearest early details disclosed by YG.
First YG Boy Group Since Treasure in 2020
The upcoming debut is significant within YG Entertainment’s release schedule because it follows a long gap in boy-group launches. Yonhap reported that the September act would be YG’s first boy-group debut since Treasure in 2020.2 SBS News also placed the project in the same context, reporting that the new team follows Treasure’s 2020 debut.3
YG LIFE described the project as the agency’s first new boy group in six years, matching the timeline cited by Korean outlets.1 Asia Business Daily also reported that YG announced plans to release a five-member male group in September and described it as the company’s first new boy group in six years.5
The announcement came as part of a broader YG update on second-half activities. Asia Business Daily identified the announcement video as “BABYMONSTER, TREASURE, AND UPCOMING ROOKIES,” and reported that the company also discussed plans involving Babymonster, Treasure, and Bigbang’s 20th-anniversary world tour.5
While those broader plans provide company context, the confirmed focus for the new boy group remains narrow. YG has disclosed the debut timing, the number of members, and the fact that additional new IP and rookies will be revealed sequentially. The Korea Economic Daily reported that YG plans to disclose new IP and rookies in sequence after presenting the new five-member boy-group plan through the company’s official blog video.6
What Is Still Unconfirmed
Several details commonly attached to a K-pop debut have not yet been made public. The sources do not provide the group’s official name, member profiles, nationalities, ages, leader position, performance roles, music style, title track, album type, showcase schedule, or promotional timetable.
That absence matters because early debut reporting can sometimes lead to speculation around trainees, project names, and possible pre-debut content. In this case, the available source material supports only the confirmed September target and five-member structure. Any claim beyond those points would require a later official update or additional reporting.
The announcement also refers to YG’s intention to reveal new IP and new artists sequentially, including the tentative girl group project Next Monster.1 However, that separate project has not been identified as part of the September boy-group debut in the provided source material.
For now, the new act is best understood as a confirmed upcoming five-member YG boy group with a September debut window, rather than a fully disclosed launch campaign. Further details are expected to define how the group will be positioned within YG’s artist roster and how the company will distinguish it from Treasure.
