CORTIS has reached another major chart milestone in the United States with its latest title track, 'REDRED.' According to Billboard's latest chart dated May 16, the song entered the Bubbling Under Hot 100 at No. 17. The chart ranks songs that are just outside the main Hot 100, using similar performance indicators such as streaming, radio airplay and sales. For a rookie K-pop boy group that debuted less than a year ago, entering this chart is a notable sign of growing traction in the U.S. market.
The achievement stands out because it comes only about nine months after CORTIS made its debut. Korean reports noted that the group is the first K-pop boy group to debut within the past five years and chart on Bubbling Under Hot 100. That makes 'REDRED' more than a domestic comeback success. It shows that the group's audience is expanding into global listening markets where song-level performance, not only album sales, matters.
'REDRED' has also continued to rise on Billboard's global charts. The track climbed to No. 43 on Global 200 and No. 24 on Global Excl. U.S., while the group's second mini album, 'GREENGREEN,' entered the World Albums chart at No. 8. Together, these results suggest that CORTIS' current momentum is not limited to one metric. After drawing attention for strong first-week album sales, the group is now adding U.S. song-chart performance to its growth story, positioning CORTIS as one of the most closely watched new-generation K-pop boy groups of 2026.
