SMTR25

SMTR25 is the public trainee team at the center of SM Entertainment's 2026 rookie cycle. Instead of waiting until a final lineup is locked, the company pushed the 15-member team into the market early through Mnet's Reply High School, turning pre-debut development into weekly content, fan meetings, and a measurable audience test.

That rollout matters because SM is treating the team like a live property, not a hidden trainee pool. The April 2026 OST single We Go Up gave the project a real release point, while the Reply High School fan meeting tour moved the trainees from digital curiosity into ticket-selling territory. Woolin, Songha, Nicholas, and the wider cast are now building name recognition before the company narrows the final debut structure.

For HITKULTR, SMTR25 is less about a finished idol identity than a rare look at how a major label stress-tests its next generation in public. The team already sits between survival-show storytelling, official SM infrastructure, and the wider SM Entertainment system that has historically launched some of K-pop's biggest acts.

Fans Also Ask

What is SMTR25?
SMTR25 is SM Entertainment's public male trainee team, introduced as part of the company's 2026 rookie cycle. Instead of staying behind closed doors, the 15 trainees were pushed into the market through Mnet's Reply High School, official social channels, fan meetings, and the April 2026 OST single We Go Up.
How many members are in SMTR25?
SMTR25 currently has 15 publicly introduced trainees: Hamin, Nicholas, Hanbi, Songha, Daniel, Hyunjun, Kassho, Justin, Haruta, Kachin, Tata, Jaewon, Woolin, Sadaharu, and Charlie. SM has treated the team as a public trainee pool, so the final debut lineup can still change as the project develops.
What is Reply High School?
Reply High School is Mnet's 2026 reality project built around SMTR25. The show places the trainees inside a school-themed format and uses missions, performances, and variety storytelling to introduce them individually before SM Entertainment confirms its final rookie-group structure.
Did SMTR25 release any music?
Yes. SMTR25 released We Go Up in April 2026 as an OST single connected to Reply High School. The track gave the trainee project a formal commercial release, which matters because it moved the team beyond teaser content and into a measurable music rollout under SM Entertainment.
Will all 15 SMTR25 members debut together?
Not necessarily. SM Entertainment has positioned SMTR25 as a public trainee team rather than a locked debut lineup. The company can keep the full cast visible through content and events, then split or narrow the final members when the official rookie-group launch strategy is ready.
