CORTIS’s ‘GREENGREEN’ Surpasses 4.1 Million Sales in Breakout Second-Year Milestone

CORTIS has reached a major commercial milestone only one year into the group’s career. The group’s second EP, ‘GREENGREEN,’ had sold approximately 4.1 million copies as of September 17, based on Circle Chart figures. That total moves the release beyond the four-million threshold and marks a sharp increase from the group’s first EP.

The achievement also gives ‘GREENGREEN’ a rare place in the 2026 market. It is only the second album released this year to exceed four million sales, following BTS’s ‘ARIRANG.’ For a group still at an early point in its career, joining that limited tier makes the result notable both as a standalone sales figure and as evidence of how quickly CORTIS’s audience has expanded.

A second EP with a much larger reach

‘GREENGREEN’ has accumulated nearly twice the sales of CORTIS’s debut EP, ‘COLOR OUTSIDE THE LINES.’ The comparison is significant because it measures growth across consecutive releases rather than relying on a single opening-week result. In practical terms, the group’s second project has reached a substantially broader buying audience than the release that introduced it.

That kind of jump can reshape expectations around a young act. A debut establishes an initial fan base and public identity, while a follow-up tests whether attention can be converted into durable demand. By more than doubling down on the momentum of its first year, CORTIS has shown that interest in the group did not peak with its arrival. Instead, the audience supporting the group’s physical releases appears to have widened considerably. The result also suggests that the group’s early supporters remained engaged while new listeners joined them, creating a larger base around the second project. That combination is especially valuable at a stage when an act is still defining its long-term place in a crowded market.

The 4.1 million figure is also a cumulative total, which highlights sustained purchasing rather than a momentary spike. Album sales at this level reflect a large-scale connection between a release and listeners willing to support it directly. For CORTIS, the milestone makes ‘GREENGREEN’ the clearest commercial marker yet of the group’s upward trajectory.

What the four-million mark means for CORTIS

Crossing four million does more than add an impressive number to the group’s record. It places CORTIS alongside one of the year’s biggest album releases and gives the group a concrete benchmark against which future projects will be measured. The comparison with BTS’s ‘ARIRANG’ underscores how uncommon the threshold remains in 2026.

At the same time, the result raises the scale of attention around the group’s next moves. Rapid growth can create pressure to repeat exceptional numbers, but it can also provide more room for creative development and longer-term planning. CORTIS now enters its next phase with proof that its audience is capable of supporting a release at the highest commercial level. Future results will naturally be judged against ‘GREENGREEN,’ yet the current milestone already stands on its own as evidence of extraordinary demand. Whether that pace continues or settles, the group has secured a durable reference point for evaluating its progress.

The milestone is especially striking because it arrives so early. With only a year separating the group’s arrival from membership in the so-called quadruple-million-seller club, CORTIS has compressed a level of sales growth that often takes acts much longer to achieve. The near-doubling from ‘COLOR OUTSIDE THE LINES’ to ‘GREENGREEN’ gives that rise a clear numerical shape.

For now, ‘GREENGREEN’ stands as CORTIS’s defining sales achievement: approximately 4.1 million copies, nearly twice the cumulative total of the debut EP, and one of only two 2026 albums above four million. Those figures establish the group as one of the year’s strongest album performers and turn its next release into an important test of how far that momentum can continue.
