CORTIS, a boy group nine months into their debut, continues to show upward momentum even after concluding their activities. Their title track 'REDRED' from the mini album 'GREENGREEN' released in May topped major domestic music charts including Melon and Bugs, and achieved 100 million streams on Spotify on the 18th. This marks the fastest such milestone for a boy group that debuted within the last five years. Their monthly listeners on Spotify reached a record high of 12.33 million, with the largest proportion of listeners from the United States, demonstrating their global popularity. On the 12th, CORTIS was uniquely invited among K-pop artists to perform at a street cheering event for the Korea vs. Czech Republic match for the 2026 FIFA North/Central America World Cup held at Gwanghwamun Square in Seoul. Members appeared in red uniforms symbolizing the Red Devils with face and arm paintings, leading chants and cheers. They also shared a short-form video where they rewritten 'REDRED' lyrics for soccer cheering on official SNS, maintaining engagement with fans. These activities demonstrate that CORTIS has expanded beyond music into advertising and sports events, establishing themselves as cultural icons for younger generations. With their chart-topping songs, sold-out North American tours, and entries into global festivals, industry and fans are eagerly anticipating CORTIS's future achievements as they approach their first anniversary.
