Why does Stray Kids have eight members instead of nine?

The group debuted with nine members but Woojin left in October 2019. Stray Kids has promoted as an eight-member group ever since, with no further lineup changes.

Who produces Stray Kids' music?

Most of it is self-produced by the in-house trio 3RACHA — Bang Chan, Changbin and Han — which is central to the group's loud, maximalist sound.

Who is the leader of Stray Kids?

Bang Chan. Unusually, he handpicked every member from JYP's trainee list before the 2017 survival show, rather than the agency's executives choosing the lineup, and he anchors the production team 3RACHA.

How does Stray Kids compare to other JYP boy groups?

Stray Kids is JYP's most commercially dominant boy group internationally, distinguished by a self-produced, harder-hitting sound and a streak of Billboard 200 No. 1 albums.

TIMELINE

The journey

ORIGIN

The survival show

2017 — 2018

Stray Kids formed through their own JYP/Mnet survival show, where the trainees fought to keep the lineup intact — a story that hard-wired the underdog identity into the fanbase. The in-house production crew 3RACHA (Bang Chan, Changbin, Han) was the creative engine from before debut.

Lineup: Debuted as nine members in March 2018

DEBUT

District 9 & noise-music identity

2018 — 2019

Debut single District 9 and follow-ups built a loud, aggressive, self-produced sound that set the group apart from JYP's softer acts. The early era established 3RACHA's writing and the group's reputation for high-intensity performance.

Anchor track: District 9

Lineup: Woojin left the group in October 2019, reducing the lineup to eight

BREAKTHROUGH

God's Menu & the breakthrough

2020 — 2021

Go Live and the single God's Menu turned the maximalist concept into a commercial breakthrough, and Noeasy pushed the group toward million-seller status. The eight-member lineup found its definitive, hard-hitting identity here.

Anchor track: God's Menu

GLOBAL

Billboard No. 1 run

2022 — 2024

Starting with Oddinary, Stray Kids landed a remarkable streak of consecutive No. 1 debuts on the Billboard 200 with Maxident, 5-Star, Rock-Star and ATE, joining the rarest tier of chart-dominant acts. Stadium-scale touring and festival headline slots followed.

STADIUM

Karma & This & That

2025

Karma made Stray Kids the first act to debut at number one on the Billboard 200 with its first seven entries, sold 3.03 million copies in its first week and helped make them IFPI's second best-selling artist of 2025. In 2026 This & That stretched the streak to nine, the Run It World Tour began in Seoul, and they headlined Rock in Rio.
