Five-Member Girl Group RESCENE Closes In on BTS
RESCENE, the five-member girl group made up of Wonyi, Reev, Minami, May, and Jena, ranked second in the August 2026 idol group brand reputation index, trailing only BTS. In an analysis released on August 17 by the Korea Corporate Reputation Research Institute, BTS topped the list with a brand reputation index of 7,107,645 points, followed by RESCENE with 7,045,802 points. The gap between the two groups was just 61,843 points.
RESCENE’s score jumped 40.50% in a single month, up from 5,014,734 points in July. BTS also rose during the same period, climbing 9.04% from 6,518,675 points, but RESCENE’s increase was far steeper. IVE placed third, Seventeen fourth, and TWICE fifth. The ranking does not separate boy groups and girl groups, comparing all idol groups within a single category.
RESCENE didn’t take the top spot, but the fact that the gap with the leader amounts to less than 1% of the total index is notable. Still, this figure doesn’t compare music sales or concert attendance. It should be read as an analysis of how active engagement, mentions, and content circulation around each group were online during a specific period.
An Online Attention Metric, Not a Music Chart
The brand reputation index is a private-sector metric compiled by the Korea Corporate Reputation Research Institute based on online big data. It quantifies consumer participation, exposure through media and online outlets, communication among users, and spread across communities, then adds them together. Unlike counting a single type of consumption such as streaming numbers or album sales, it looks at multiple forms of online attention at once.
To readers outside Korea, this ranking might look like a music chart or an official industry statistic, but it works differently. Brand reputation centers on the volume and movement of online material generated during the survey period. That means the ranking can shift quickly based on activity concentrated in a short window, such as a new release, a broadcast appearance, or fans sharing posts. A single month’s ranking doesn’t settle a group’s long-term popularity or overall commercial performance.
This analysis drew on 115,388,244 pieces of idol-group-related big data collected between July 17 and August 17, a 27.17% increase from the previous month’s 90,733,805. Even as the volume of online material surrounding idols overall grew, RESCENE’s index rose by an even larger 40.50%. That suggests the group’s own online visibility expanded alongside the broader rise in market attention.
Communication and Community Drove the Rise
RESCENE’s breakdown showed 1,319,080 points for participation, 1,226,672 for media, 2,210,406 for communication, and 2,289,643 for community. Of the four categories, communication and community each topped 2 million points, accounting for the largest share. Combined, the two categories totaled 4,500,049 points, roughly 64% of the group’s overall brand reputation index.
The participation index measures how much consumers reacted to the brand, while the media index tracks exposure flowing through articles and content. The communication and community indices are more about how often the group was mentioned online and how widely related information was shared and spread. In RESCENE’s case, activity generated by users and fan communities, rather than plain media exposure, was the central driver behind the overall index increase.
This illustrates how much weight online activity carries within Korean pop music fandoms. Fans don’t stop at listening to music and buying albums; they share videos and photos of the group, react to posts, and start new conversations within communities. Each of these actions is small on its own, but in big data analysis, they add up as signals that shape a group’s online presence.
Consistency Matters More Than a Narrow Margin
The fact that RESCENE posted a comparable overall index to BTS shouldn’t be read as meaning the two groups’ global fandom size or cumulative achievements have become equal. BTS’s community index stood at 3,956,580 points, higher than RESCENE’s, and the way each group’s sub-indices formed differed as well. It’s worth keeping in mind that brand reputation is a monthly metric that captures activity within the survey period, with the limitations that come with that.
The core of this result is that RESCENE rapidly raised its visibility in online communication and community activity within a single month. Rather than the No. 2 ranking itself, the fact that fan mentions and content spread made up most of the overall index better explains the nature of the rise. What remains to be seen is whether this concentrated online attention carries into the next survey and translates into growth in the media and participation categories as well.
