CORTIS’ GREENGREEN Surpasses 4 Million Sales as Rookie Group Reaches New Milestone
CORTIS has officially reached one of the largest physical sales landmarks in recent K-pop history. According to reporting from Yonhap based on the latest Circle Chart data covering September 6–12, 2026, the group’s second EP, GREENGREEN, has surpassed 4.1 million cumulative copies sold.
The milestone makes GREENGREEN only the second Korean album released in 2026 to cross the four-million threshold, joining BTS’ ARIRANG.
Reaching more than 4.1 million cumulative units just four months after its release on May 4, 2026, the album demonstrates an unusual degree of ongoing sales longevity that extends far beyond standard first-week purchasing cycles.
Combined with sustained momentum on international charts—including an 18-week run on the Billboard 200—and strong domestic digital streaming performance for lead tracks like “REDRED,” GREENGREEN has established CORTIS as one of the defining commercial stories of 2026.
GREENGREEN Crosses the 4 Million Mark
In Korean music industry terminology, passing four million cumulative physical sales places an album into “quadruple million-seller” status.
While several legacy K-pop acts have achieved multi-million sales milestones over multi-year career spans, reaching more than 4.1 million copies within four months of release remains an elite tier reserved for the market’s absolute top performers.
The primary news hook comes directly from Circle Chart’s tracking period for September 6–12, 2026. Based on figures reported by Yonhap, GREENGREEN achieved approximately 4.1 million total sales across physical retailers and distributors.
The achievement is particularly notable given the competitive landscape of 2026 Korean album releases. Across the entire domestic recording industry this year, only two titles have managed to pass four million sales on Circle Chart. By joining BTS’ ARIRANG at this level, CORTIS has verified that its audience base can sustain top-tier physical sales numbers across multiple months.
From 2.31 Million First-Week Sales to 4.1 Million
While crossing four million copies is a significant single headline, the broader story lies in how GREENGREEN arrived at this figure. Rather than relying on a massive opening week followed by a sharp drop in activity, the EP has maintained continuous sales velocity throughout the summer.
The album’s sales trajectory illustrates a steady, compounding multi-month expansion:
- May 4 (Opening Day): CORTIS sold 1,196,961 copies on the first day of release alone, immediately crossing the million-seller threshold within 24 hours.
- May 4–10 (First Week): On Hanteo Chart, GREENGREEN closed its opening week with 2,313,291 copies sold, marking one of the largest first-week debuts of the year.
- July 12–18 (11 Weeks Post-Release): Circle Chart data confirmed that cumulative sales had reached 3,099,000 copies, making it a triple-million seller in less than three months.
- September 6–12 (18 Weeks Post-Release): Circle Chart’s latest tally confirmed the album had crossed approximately 4.1 million cumulative sales.
This progression highlights an essential detail: GREENGREEN didn’t simply collect four million sales from pre-orders. Between mid-July and mid-September, the album added roughly another million units to its cumulative tally—a remarkable post-launch run that demonstrates steady catalog purchasing and continuous fan base expansion.
A Dramatic Jump From CORTIS’ Debut
To fully understand the scale of GREENGREEN’s performance, its figures must be contextualized alongside CORTIS’ entry into the market. The group made its official debut under BIGHIT MUSIC in September 2025 with the EP COLOR OUTSIDE THE LINES.
When COLOR OUTSIDE THE LINES was released, it registered 436,367 first-week sales on Hanteo Chart—a very strong opening performance for a newly launched act. However, when GREENGREEN arrived eight months later in May 2026, its first-week total of 2,313,291 copies represented roughly a 430% increase compared to their debut week.
First-Week Sales Comparison (Hanteo Chart)
Very few groups in K-pop history have demonstrated a growth curve this steep between their first and second projects. The nearly five-fold jump in first-week sales from debut to follow-up indicated that CORTIS’ international and domestic fan base expanded drastically during the eight-month gap between releases.
Only BTS’ ARIRANG Has Also Crossed Four Million
The physical sales environment in 2026 has seen shifting market dynamics, making high multi-million physical sales milestones increasingly difficult to achieve. Against this backdrop, GREENGREEN’s arrival at 4.1 million units gains added significance when viewed across the entire Korean music industry.
According to Circle Chart reporting featured in Yonhap’s September 17 news coverage, only two Korean albums released throughout 2026 have successfully surpassed four million cumulative copies:
- BTS — ARIRANG
- CORTIS — GREENGREEN
Rather than serving as a direct head-to-head ranking, this factual comparison underscores the rare tier of commercial impact CORTIS has unlocked. Crossing the four-million threshold alongside an established global phenomenon like BTS establishes CORTIS as one of the leading commercial powerhouses of the current K-pop landscape.
GREENGREEN Is Also Having a Long U.S. Chart Run
A key strength of CORTIS’ commercial profile is that physical sales in Asia are matched by sustained international performance in Western markets. The global footprint of GREENGREEN is clearly reflected in its performance on the United States charts.
According to Yonhap’s September 17 update, GREENGREEN:
- Debuted at No. 3 on the Billboard 200 chart upon its release in May 2026.
- Has remained on the Billboard 200 for 18 consecutive weeks as of mid-September.
Earlier Billboard tracking confirmed that GREENGREEN had already established a personal record for CORTIS by becoming the longest-charting Billboard 200 entry of the group’s career. Maintaining a presence on the primary U.S. album chart for over four months demonstrates that the album’s physical sales figures are supported by active consumption, digital downloads, and streaming across North America.
REDRED Helps Drive the Album’s Continued Momentum
Physical album longevity is rarely sustained by collector interest alone; it typically requires consistent public interest in the music itself. BIGHIT MUSIC specifically attributed GREENGREEN’s steady, multi-month sales performance to continuing listener engagement with key tracks on the six-song EP, particularly “REDRED” and “YOUNGCREATORCREW.”
According to Yonhap, agency representatives noted that ongoing domestic streaming and digital interest in these tracks helped maintain interest in the physical album long after the initial promotion period concluded.
The digital metrics confirm this trend:
- Circle Digital & Streaming Charts: Circle Chart reported that “REDRED” secured the No. 1 spot on both the Digital Chart and Streaming Chart for the month of July 2026, proving that the project enjoyed massive general-public popularity in South Korea throughout the summer.
- Global Spotify Impact: SBS previously reported that “REDRED” became the first song by a K-pop boy group that debuted within the last five years to enter Spotify’s Daily Top Songs Global chart.
This creates a balanced commercial profile across three major sectors:
| Sector | Metric / Performance |
| Korean Physical Sales | 4.1M+ cumulative copies (GREENGREEN) |
| Korean Digital Performance | No. 1 on Circle Digital & Streaming Charts (July 2026) |
| U.S. Mainstream Presence | Billboard 200 No. 3 debut + 18 consecutive weeks |

While GREENGREEN accounts for the majority of recent headlines, CORTIS’ debut work has also continued to move significant inventory throughout 2026.
According to BIGHIT MUSIC figures cited by Yonhap, the debut EP COLOR OUTSIDE THE LINES (originally released in September 2025) has reached approximately 2.3 million cumulative copies sold. Notably, roughly 1 million of those copies were purchased in 2026 alone, demonstrating that new fans discovering the group through GREENGREEN have been actively buying their back catalog.
CORTIS Cumulative Album Sales (BIGHIT MUSIC Data)
With COLOR OUTSIDE THE LINES at ~2.3 million and GREENGREEN at ~4.1 million, CORTIS’ first two EPs have generated more than 6.4 million combined copies in cumulative sales. Generating over 6.4 million album sales across just two releases within a 12-month span represents one of the fastest commercial accelerations for any new group in modern Korean music history.
What the Numbers Say About CORTIS’ First Year
Examining CORTIS’ performance data from September 2025 through September 2026 reveals a distinct set of factual takeaways regarding their commercial position:
- High Catalog Velocity: The addition of 1 million copies to their 2025 debut EP during 2026 indicates strong onboarding of new fans who consume the group’s entire discography rather than focusing strictly on current singles.
- Post-Launch Longevity: Gaining approximately 1 million sales on GREENGREEN between July (3.1M) and September (4.1M) proves that physical purchasing remained active well after primary TV and broadcast promotions ended.
- Dual-Market Balance: Maintaining the No. 1 spot on Circle’s monthly streaming chart alongside an 18-week run on the Billboard 200 demonstrates that CORTIS enjoys both domestic general-public popularity and structured international fandom support.
Conclusion
Passing 4.1 million sales for GREENGREEN marks a definitive moment in CORTIS’ early career. By moving from a 436,000-copy opening week in late 2025 to a quadruple-million seller in mid-2026, the group has established an extraordinarily high commercial ceiling.
With more than 6.4 million combined EP sales across their first two projects, an 18-week Billboard 200 run, and major domestic digital hits under their belt, CORTIS enters the autumn of 2026 not merely as an award-winning rookie act, but as one of the central pillars of contemporary K-pop physical and digital chart performance.
