CORTIS has officially set a new record as the fastest K-pop group to reach 10 million followers on Instagram. Their official account reached the milestone around 3:30 PM on February 21, 2026, just six months after their first post was shared in August last year. This rapid growth makes them the first K-pop group debuted within the last five years to surpass the 10 million follower mark. Beyond Instagram, CORTIS also maintains the largest following among boy groups debuted in the same period on other major platforms, including TikTok (9.5 million), YouTube (3.12 million), and the global fan community Weverse (3.07 million).
This consistent expansion is driven by the group's high visibility even after concluding official promotions for their debut album 'Color Outside the Lines' in September last year. Their performances at various domestic and international award ceremonies sparked significant online engagement, which translated into a steady rise in followers. Recently, their growth rate accelerated further due to growing demand from the North American market. CORTIS became the first Korean act to headline the 'NBA Crossover Concert Series' and performed the halftime show for the '2026 Ruffles® NBA All-Star Celebrity Game', drawing a wave of new international fans.
The digital popularity of CORTIS has established them as a cultural fixture for Gen Z, with their fashion and visual aesthetics trending globally. This influence has led to high-profile collaborations with major brands and organizations such as Apple, NBA, MLB, Red Bull, and Acuvue. Their reach also extends into the gaming and film industries through partnerships with 'NBA 2K26' and 'Fortnite', as well as recording the track 'Mention Me' for the Sony Pictures Animation film 'Goat'. As CORTIS continues to bridge music and lifestyle content, their global footprint is expected to expand even further.
