Who Is CORTIS?
CORTIS is a five-member boy group under BIGHIT MUSIC, the agency behind BTS. The group debuted in September 2025 with their first EP, “COLOR OUTSIDE THE LINES.” Members include Martin, James, Seonghyeon, and Keonho, among others. Their second EP, “GREENGREEN,” arrived on May 4, 2026, marking their first comeback in eight months.
The debut EP has also continued to sell steadily. “COLOR OUTSIDE THE LINES” has now reached approximately 2.3 million cumulative copies, including about 1 million sold in 2026 alone. Together, CORTIS’s first two EPs have moved more than 6 million copies, a rapid sales build-up for a group still early in its career.
How Did “GREENGREEN” Reach 4 Million Sales?
The album’s path to 4 million was driven by a strong opening and sustained interest over several months. “GREENGREEN” sold 2,313,291 copies during its first week, according to Hanteo Chart data. That was roughly five times the first-week sales of the group’s debut release.
By July 2026, the EP had passed 3 million cumulative copies on Circle Chart. About two months later, another million copies were added, pushing the total to approximately 4.1 million. BIGHIT MUSIC pointed to continued interest in songs including the title track “REDRED” and B-side “YOUNGCREATORCREW” as one factor behind the album’s sustained performance. The agency also noted that the popularity of “REDRED” naturally led to strong album sales.
CORTIS took an unconventional approach to physical releases, expanding beyond traditional albums with a range of merchandise-style formats, including an LP, lip balm, dice, and a CORTIS Ball. The group’s growing international fanbase also contributed to the album’s momentum.
Where Did “GREENGREEN” Chart Globally?
“GREENGREEN” debuted at No. 3 on the Billboard 200 in May 2026, marking one of the fastest-ever Top 3 debuts by a K-pop group excluding project groups. As of mid-September 2026, the EP has remained on the Billboard 200 for 18 consecutive weeks. On the Billboard Top Album Sales chart dated May 23, the EP debuted at No. 1 with 81,500 copies sold in the United States in the week ending May 14, according to Luminate. That was the act’s best sales week yet.
The album has also received attention in Japan, where an exclusive television broadcast of “2026 CORTIS TOUR IN JAPAN” is scheduled for October 31. An expanded version of “GREENGREEN” is also being promoted in Japan through a digital campaign.
What Else Has CORTIS Been Doing?
CORTIS has kept a busy schedule throughout 2026. The group recently wrapped up their first headlining tour, “2026 CORTIS TOUR,” with final performances in Yokohama, Japan.

The group also made their Lollapalooza Chicago debut in July 2026, performing alongside a lineup of major international artists. On July 31, CORTIS released “MOTION (feat.
