CORTIS, a five-member boy group consisting of Martin, James, Joohoon, Sunghyun, and Gunho, has surpassed 15 million followers on Instagram. The milestone was achieved approximately one year after their first post in August of last year, marking the fastest growth rate among all K-pop groups in history. Additionally, the group has recorded the highest subscriber counts among K-pop boy groups that debuted within the past five years on TikTok (15.82 million) and YouTube (6.24 million). The explosive follower growth notably accelerated following their performance at the major American music festival 'Lollapalooza Chicago' on August 1st. Currently on their '2026 CORTIS TOUR IN NORTH AMERICA' visiting six North American cities, the group has upcoming performances scheduled at Seoul's Korea University Hwajung Gymnasium on August 22-23 and at Kanagawa's Pia Arena MM in Japan on September 4-6.
