CORTIS has surpassed 1.006 billion cumulative streams on Spotify as of July 24, approaching their first debut anniversary. This achievement marks the highest stream count among boy groups that debuted within the past five years, accomplished with only two albums and 13 songs. The group now exceeds 12.7 million monthly listeners on the platform. Adding 100 million streams in less than a month since reaching 900 million on July 4, CORTIS demonstrates sustained popularity. Their second mini-album title track 'REDRED' has been a major driver of growth, accumulating approximately 160 million streams about three months after its April 20 release and maintaining around 1.4 million daily streams. By region, the United States leads their listener base, followed by Indonesia, South Korea, the Philippines, Brazil, and Japan.
