CORTIS has passed 1.5 billion cumulative streams on Spotify just 15 months after the group’s debut, cementing the BigHit Music boy group’s status as one of the defining breakout acts of K-pop’s fifth generation. According to Spotify data dated November 10, the group’s total streams across all released songs reached 1,500,550,000 — the highest figure among K-pop boy groups that debuted within the last five years.
The timing matters as much as the number. CORTIS debuted in August 2025, so the 1.5 billion mark arrived in just over a year — a pace no other boy group from the last five years of debuts has matched. In a generation of boy groups fighting for attention in an increasingly crowded market, the figures suggest CORTIS has broken away from the pack rather than merely keeping up with it.
The milestone is striking for how little music it took to reach it. The 1.5 billion streams come from just 16 tracks, spanning the group’s first two mini albums and ‘Mention Me,’ their contribution to the Sony Pictures Animation film ‘GOAT.’ Around 1.2 billion of those streams were generated in 2026 alone, a sharp acceleration on last year’s pace that underlines how fast the group’s audience has grown.
The group’s second mini album title track ‘REDRED,’ released in April, remains the engine of that growth. The song has now passed 276 million streams and is on course to break 300 million before the end of the year. It is far from a one-song story: first mini album tracks ‘GO!’ at 267 million, ‘FaSHioN’ at 248 million, ‘JoyRide’ at 120 million and ‘What You Want’ at 119 million have all continued to climb steadily months after release.
CORTIS’s monthly listener count tells the same story. The group set a personal record of 12,947,465 monthly listeners on August 27 — the third-highest peak ever recorded by a K-pop boy group — and has held above 10 million listeners ever since. The United States accounts for the largest share of that audience, followed by Indonesia, Brazil, Mexico, South Korea, Japan, the Philippines and India, a spread that points to a genuinely global fanbase rather than one concentrated in a single market.
The streaming numbers cap a year in which CORTIS moved from promising rookies to a group playing the world’s biggest stages. Their first tour, ‘PUT YOUR PHONE DOWN,’ sold out across South Korea, North America and Japan, and the group was the only K-pop act invited to perform at both Lollapalooza Chicago and the Formula 1 Singapore Grand Prix 2026, where they played 15 songs for an estimated 60,000 fans on the main stage.
Much of the attention around CORTIS has centered on the members’ hands-on role in their own work. Martin, James, Juhoon, Seonghyeon and Keonho plan and produce their own creative output as a self-described ‘young creator crew,’ an identity that Korean media have dubbed a ‘young creator crew syndrome’ reaching beyond music into wider youth culture. The group debuted under BigHit Music, the HYBE label behind BTS, and has carried the ‘BTS’s younger brother group’ tag since before their debut — a label the streaming figures now suggest they are outgrowing on their own terms.
The momentum now carries into awards season. CORTIS are nominated in major categories at the 18th Melon Music Awards on November 15 at Seoul’s Gocheok Sky Dome, including Artist of the Year, Album of the Year and Best Song. With ‘REDRED’ closing in on 300 million streams, the group heads into the ceremony as one of the year’s defining breakout stories — and the 1.5 billion milestone is the number that proves it.
