They reached this milestone just six months after debut, showcasing an unusual rate of growth.
Their participation in NBA events is also strengthening their presence in the North American market.
[TV Daily, Kim Jinsuk] K-Pop group CORTIS has achieved a remarkable milestone by surpassing 10 million followers on Instagram in a short span of time. Their official account hit this impressive number at 3:30 PM on the 21st, just six months after their first post was shared in August last year.
CORTIS (members: Martin James, Juhoon, Seonghyun, Gunho) is now the first K-Pop group to reach this milestone within the first six months since their debut in the past five years. As of 7 AM on the 22nd, they have also gained 9.5 million followers on TikTok, 3.12 million on YouTube, and 3.07 million on the global fan platform Weverse, making them the boy group with the highest follower counts in both TikTok and YouTube among those who debuted in the last five years. Their rapid growth is undeniable.
Even after concluding their official activities for their debut album 'COLOR OUTSIDE THE LINES' in September last year, their social media follower count has continued to rise. This increase is attributed to the buzz generated by their performances at various award shows and concerts. Moreover, they recently became the first Korean artists to headline the 'NBA Crossover concert series' and performed during the halftime show of the 2026 Ruffles® NBA All-Star Celebrity Game, signaling a growing recognition in the North American market.
CORTIS is a rapidly rising group within the K-Pop scene. Their swift achievement of 10 million Instagram followers has catapulted their fanbase's interest. This surge can be attributed not only to their musical talent but also to their strategic use of social media.
Even after wrapping up official promotions for their debut album 'COLOR OUTSIDE THE LINES', they continue to receive sustained attention. This is further intensified by the unique stages they showcased at various award shows and performances, which have allowed them to establish stronger connections with their fans.
Moreover, their collaboration with the NBA has significantly contributed to their expansion into the North American market, enhancing their global influence. Thus, CORTIS is solidifying its position as a noteworthy global artist while building a broader fanbase both domestically and internationally.
