June 2026 Boy Group Brand Reputation Rankings: BTS Still Reigns, But CORTIS And Stray Kids Are Catching Up Fast

Another month, another shake-up in the K-pop world’s most-watched popularity chart. The Korean Business Research Institute has dropped its June brand reputation rankings for boy groups, and while one familiar name continues to dominate, the real story this month is about explosive growth from rising acts.

How Are These Rankings Calculated?

The rankings are based on an analysis of consumer participation, media coverage, interaction, and community indexes, using big data collected between May 13 and June 13. This makes the list less about pure popularity polls and more a snapshot of who’s genuinely dominating conversations online.

Top 5 Breakdown

BTS Holds the Crown, Again

It’s no surprise that BTS retained the top spot with a brand reputation index of over 10 million for June. Their keyword analysis was dominated by terms like “world tour,” “ARMY,” and “Busan concert,” showing just how much their global touring activity continues to fuel conversation. With a near-93% positivity score, the group remains the gold standard of brand health in the industry.

The Real Surprise: CORTIS and Stray Kids Surge

What’s grabbing attention this month isn’t the top spot, it’s the massive momentum behind newer and resurgent acts. CORTIS saw their index skyrocket by nearly 148% compared to last month, catapulting them straight into second place. Meanwhile, Stray Kids posted a remarkable 140% increase, signaling that their recent activities have struck a major chord with fans and casual observers alike.
