CORTIS is celebrating a career milestone on the Billboard 200. Their second EP, "GREENGREEN," has now spent six consecutive weeks on Billboard's Top 200 Albums chart, making it the longest-charting release in the group's history.

The EP spent its first five weeks inside the top 50 before holding relatively steady in the rankings during its sixth week on the chart. The sustained performance marks a significant achievement for the group as they continue building momentum in the U.S. market.

"GREENGREEN" represents CORTIS's latest project and demonstrates growing listener interest in their releases stateside. K-pop acts typically face steep competition for chart placement, making any extended run on Billboard's main albums chart noteworthy. The six-week streak shows the EP resonated with audiences beyond initial release week, which often sees inflated numbers.

For context, many K-pop releases experience their strongest charting performance in their debut week before dropping significantly as casual listeners move on. CORTIS's ability to maintain chart presence across six weeks suggests genuine, sustained interest from both dedicated fans and broader audiences.

The group's performance on Billboard 200 reflects the broader growth of K-pop in mainstream U.S. markets. More Korean acts are achieving extended chart runs, though CORTIS's six-week appearance remains a personal best for the group.

As CORTIS continues their momentum, "GREENGREEN" serves as proof that quality releases can maintain listener engagement beyond the initial buzz period. Whether the EP continues climbing or eventually drops off the chart in coming weeks, the six-week run already stands as a career high for the group on Billboard's premier albums ranking.
