CORTIS has delivered one of the strongest K-pop album performances of 2026 with its second mini album, 'GREENGREEN.' According to Hanteo Chart, the album sold 2,313,291 copies between May 4 and May 10, taking No. 1 on the weekly album chart. The figure marks a dramatic rise from the group's first mini album, 'COLOR OUTSIDE THE LINES,' which recorded 436,367 first-week sales last year.
The pace of the sales growth is especially notable. 'GREENGREEN' sold around 1.2 million copies on its first day alone, immediately making CORTIS a million-seller, and passed the double-million mark within four days. That momentum places the album among the highest first-week K-pop releases of the year, behind BTS' 'ARIRANG,' and gives the group a clear breakthrough moment in the current boy group landscape.
For a team still less than a year into its career, the scale of this result suggests more than a successful comeback cycle. It points to a sharply expanding fandom, stronger purchasing power, and growing visibility across both domestic and global K-pop markets. CORTIS' latest numbers also show that the group's rise is being driven by measurable demand rather than short-term curiosity, making 'GREENGREEN' one of the key idol-market stories to watch this week.
