IST Entertainment officially announced the debut of their new boy group TUNEXX, scheduled for March 2026. The company revealed the finalized lineup on January 15, marking another addition to this year's crowded rookie field.

TUNEXX will consist of four members: Park Dong Gyu, Kim Si Hwan, Arctic, and Kim In Hu. Three of these members gained recognition through their participation in Mnet's survival show "BOYS II PLANET," while Kim In Hu joins as a newly added member to complete the group.

The announcement comes as K-Pop continues its strong momentum into 2026, building on the industry achievements highlighted in recent year-end chart releases. IST Entertainment, home to groups like APINK and VICTON, is positioning TUNEXX to capitalize on the current global interest in K-Pop acts.

While specific details about their debut concept, title track, or promotional schedule remain under wraps, the March timeline suggests fans can expect teasers and pre-debut content to begin rolling out soon. The inclusion of "BOYS II PLANET" contestants gives the group built-in recognition, as survival show participants often bring dedicated fanbases from their competition appearances.

IST Entertainment's decision to debut a new boy group reflects the company's expansion strategy and confidence in the current market conditions. With established acts continuing to dominate charts globally and new groups finding success, the timing appears strategic for launching fresh talent.

The entertainment industry will be watching to see how TUNEXX positions itself among the competitive 2026 rookie class, particularly given their survival show connections and IST's track record with idol groups.
