“Who’s the most popular idol group in Korea right now?” The honest answer: there isn’t one answer. Ask by buzz, by streams, by album sales, or by global reach — and you’ll get a different #1 each time. Below, I have lined up the brand reputation rankings, music streaming charts, first-week album sales, and global metrics side by side, as of July 2026, to paint the fullest picture of who is actually ruling K-pop right now. And yes, the RESCENE reverse-run miracle — the late-blooming chart resurgence everybody has been talking about — gets its proper spot in the data.

The short version

Girl groups — The steady heavyweight is IVE (February 2026 full album REVIVE+, pre-release BANG BANG scored a Perfect All-Kill). But the hottest story of 2026 is RESCENE — a #1 on Melon two years after debut, plus the #1 spot on the July girl group individual brand reputation chart (Woni).

Boy groupsBTS returned as a full group with their fifth studio album ARIRANG (first week: ~4.17 million copies) and remains untouchable at #1. The rookie to watch is CORTIS — Billboard 200 #3, Forbes 30 Under 30 Asia, and #2 on the July brand reputation chart.

Different metrics, different rankings. Brand reputation favors buzz (RESCENE, CORTIS). Sales and global scale favor established giants (BTS, IVE, BLACKPINK).

RESCENE absolutely belongs in this conversation. Their buzz and reverse-chart-run metrics are elite-tier right now. That is one of the core stories of this article.


The most popular girl groups in Korea, mid-2026

If you have to pick one name for consistent dominance, it is IVE. If you have to pick the group with the most heat this exact moment, it is RESCENE. IVE started 2026 with a Perfect All-Kill (PAK) — topping all major real-time and daily charts simultaneously — with their pre-release single BANG BANG from the February full album REVIVE+. The title track BLACKHOLE also settled comfortably in the upper reaches of domestic and international charts. Meanwhile, the July girl group brand reputation rankings threw a curveball: the reunion project group I.O.I grabbed the #1 spot, with RESCENE right behind at #2. The top line of any ranking is always going to shift with comebacks and events.

Below is the girl group landscape as of July 2026 — factoring in buzz, streaming, album sales, and global performance together.

How the rankings were built: the Korea Corporate Reputation Research Institute’s monthly girl group brand reputation big-data rankings (June–July 2026), Melon and Genie streaming chart performance, Circle Chart (formerly Gaon) album sales data, and global metrics (Billboard, world tours). Temporary reunion projects like I.O.I — which spike for a month and fade — are noted separately from the ongoing rankings.


The most popular boy groups in Korea, mid-2026

BTS. This is not really up for debate. Their 2026 full-group comeback with the fifth studio album ARIRANG moved an estimated 4.17 million copies in the first week (Hanteo), smashing their own previous record of 3.37 million set by Map of the Soul: 7 in 2020. They held #1 on the July idol group brand reputation rankings, and BTS members — Jimin, Jungkook, Jin, V — filled out the upper ranks of the individual charts too. In the US, ARIRANG posted 641,000 equivalent album units in its first week (532,000 pure albums), the largest pure sales week for a group since One Direction in 2013, per Rolling Stone.

Among rookies and rising acts, the name to know is CORTIS. Big Hit Music’s first new boy group in six years debuted on August 18, 2025, and their second mini-album GreenGreen (May 4, 2026) put up roughly 2.3 million copies on Circle Chart in its first week (The Korea Times), hit #3 on the Billboard 200 and #1 on Billboard Top Album Sales, and earned the group a spot on the Forbes 30 Under 30 Asia list — the only K-pop boy group to make the cut. On the July idol group brand reputation rankings, they landed at #2, right behind BTS.

RESCENE: the reverse chart run that defines 2026

Yes — RESCENE is the most dramatic reverse chart run story in 2026 K-pop, and that is reflected throughout this article. They are a five-member girl group (Woni, Liv, Minami, May, Zena) under The Muze Entertainment who debuted on March 26, 2024. Early on, they flew largely under the radar. That changed completely in 2026.

Here is what the shift looks like in hard numbers:

MetricDetail

New release, instant #1Their July 2026 remake single of KARA’s Pretty Girl hit #1 on Melon HOT100 (real-time) right after release
Individual brand reputation #1July 2026 girl group individual brand reputation: leader Woni ranked #1 (brand reputation index ~7.96 million, +89.8% month-over-month). #2 Jang Wonyoung (IVE), #3 Karina (aespa)
Group brand reputation #2July 2026 girl group group brand reputation: #2 overall (#1 I.O.I, #3 ILLIT)
Buzz & memesLeader Woni’s YouTube channel “Hello I’m Woni Nice to Meet You” spawned the viral “Geoje girl” and “gyaru” character memes that spread across social media in spring 2026, skyrocketing name recognition. In July rookie idol individual brand reputation, Woni and Minami took #1 and #2

The bottom line: in buzz and streaming metrics, RESCENE is effectively at the top of the game right now. But in first-week album sales and global chart performance (Billboard, etc.), they still trail the major-label heavyweights like IVE, BLACKPINK, and aespa. That is why the “most popular girl group” title splits two ways — IVE if you value consistency and scale, RESCENE if you are talking about who owns this exact moment in buzz and momentum.


Why do different rankings show different #1s? (How to read the metrics)

“Popularity” sounds like one thing, but each index measures something different. Once you understand what each one is actually counting, it becomes obvious why the rankings shake out the way they do.

MetricWhat It MeasuresWho Benefits
Brand Reputation (Korea Corporate Reputation Research Institute)Online mentions, engagement, media coverage — big-data buzzGroups riding viral moments: memes, reverse chart runs, hot rookies (RESCENE, CORTIS)
Music Streaming Charts (Melon, Genie, etc.)Domestic real-time and weekly streaming and downloadsGroups with a public-friendly hit song (IVE, RESCENE)
Circle Chart (formerly Gaon)Official album sales (first-week), streaming, downloadsGroups with massive fandom purchasing power (BTS, SEVENTEEN, ZEROBASEONE)
Billboard & World ToursUS/global sales, chart performance, tour scaleGlobal IP (BTS, BLACKPINK, Stray Kids, CORTIS)

So if you want the one-line answer to “who is the most popular group in 2026?”: by overall scale and consistency — IVE for girl groups, BTS for boy groups. By current momentum and heat — RESCENE for girl groups, CORTIS for boy groups.

A note on brand reputation rankings — They are published monthly and can swing wildly with comebacks and events. The figures and rankings in this article reflect June–July 2026 data. It is worth refreshing against the latest monthly brand reputation and Circle Chart releases right before you hit publish.
