CORTIS recorded more than 2.31 million first-week sales with its second mini album “GREENGREEN,” making the release a double-million seller within its opening tracking period. Big Hit Music said the EP sold 2,313,219 copies from May 4 to May 10 based on Hanteo Chart data, placing it at No. 1 on Hanteo’s weekly album chart.1
The figure puts the focus on CORTIS GREENGREEN as one of the clearest sales stories in K-pop for May 2026. The album had already crossed 2 million copies by its fourth day of release, before closing its first week above the 2.3 million mark.2
CORTIS First-Week Sales Reach 2.31 Million

“GREENGREEN” was released on May 4 and was tracked by Hanteo through May 10 for its first-week total. The reported 2,313,219 copies made CORTIS a double-million seller in first-week sales and gave the group the No. 1 position on Hanteo’s weekly album chart for the period.1
The sales pace was visible before the final first-week total was announced. ChosunBiz reported that “GREENGREEN” had sold 2,027,032 copies as of May 7, four days after release, citing Hanteo Chart. The report also noted that the album became a million-seller on its first day and reached double-million status in four days.2
That sequence shows a concentrated opening-week pattern: first-day million-seller status, fourth-day double-million status, and a final first-week count above 2.31 million. The available source material does not provide a daily breakdown for every day from May 4 to May 10, but it confirms the major milestones and the final first-week result.

Billboard Results Extend the Album’s Chart Story
The domestic sales result was followed by chart activity in the United States. StarNews reported that “GREENGREEN” ranked No. 3 on the Billboard 200 dated May 23, with 81,500 album sales and 5,500 SEA units.4 The same report said the title track “REDRED” had earned seven Korean music-show wins, including consecutive wins across major broadcast programs from May 13 to May 17.4
Further Billboard data placed CORTIS in the top five of the Artist 100 on the chart dated May 23. “GREENGREEN” also reached No. 1 on Billboard’s Top Album Sales and World Albums charts, while “REDRED” placed No. 38 on the Global 200 and No. 19 on Global Excl. U.S.5
Those results give the EP a multi-chart profile: a domestic first-week sales lead on Hanteo, a top-three Billboard 200 placement, and No. 1 positions on Billboard’s Top Album Sales and World Albums rankings. The source material does not provide a complete country-by-country breakdown of sales or streaming activity, so the confirmed picture is limited to the cited Hanteo and Billboard figures.
Release Campaign Included Multiple Track Videos
Before the first-week sales total was reported, CORTIS had built the release campaign around several pieces of album content. StarNews reported that four mood-sampler videos for “GREENGREEN” were released on the HYBE Labels YouTube channel at 9 p.m. on May 2. The same report said Spotify pre-saves for the album had reached 1,015,800 one day before release, and that the group planned music videos for five of the EP’s six tracks.6
After the album arrived, Billboard Japan reported that CORTIS released the music video for “ACAI,” a track from the May 4 EP “GREENGREEN.” The report said all five members participated in writing and composing the song, with MARTIN and SEONGHYEON also credited as producers.3
The available information identifies “REDRED” as the title track connected to music-show wins and global song chart placements, while “ACAI” is described as another album track with a separate music video release.43 Together, those details indicate that the sales campaign was not centered on a single piece of content alone, but on multiple tracks and videos tied to the EP.

The confirmed first-week sales figure remains the central benchmark: “GREENGREEN” sold 2,313,219 copies from May 4 to May 10, reached No. 1 on Hanteo’s weekly album chart, and continued into wider Billboard rankings after release. With the source-backed data now spanning Korean sales, U.S. album charts, and global song charts, CORTIS’s second mini album stands as a major May 2026 commercial result for the group.
