According to official data from Big Hit Music, the group achieved this feat in just 15 days, with the milestone recorded on May 19, 2026. This rapid ascent highlights the group’s accelerating global reach, as they managed to cut the time taken to reach the 100-million-stream mark by more than half compared to their debut EP, COLOR OUTSIDE THE LINES, which achieved the same milestone in 34 days.

A Meteoric Rise for a Rookie Group

Since their debut on August 18, 2025, with the single “What You Want,” CORTIS—comprised of members Martin, James, Juhoon, Seonghyeon, and Keonho—has quickly established themselves as a force in the music industry. Their debut EP, COLOR OUTSIDE THE LINES, set a high bar for rookie acts, debuting at number 15 on the Billboard 200 and reaching 200 million streams in record time.

The group’s momentum shows no signs of slowing down. With 11.85 million monthly listeners on Spotify, CORTIS continues to dominate both digital platforms and traditional charts. Their latest track, “REDRED,” has already made a significant impact, reaching the number one spot on the Melon daily chart as of May 19, 2026.

Defining a New Era of K-Pop

The name “CORTIS” is an acronym for “Color Outside the Lines,” a moniker that reflects the members’ commitment to artistic freedom and breaking away from industry norms. As Big Hit Music’s third group to debut following BTS and Tomorrow X Together, the expectations were high, but the group has consistently delivered on their promise of authenticity.

Their success extends beyond streaming numbers. Earlier this year, CORTIS made history as the first Korean boy band to perform at the NBA All-Star Game, further cementing their status as a cultural phenomenon rather than just a musical act. With accolades already stacking up from the MAMA Awards and the Golden Disc Awards, the industry is watching closely to see what this quintet does next.
