Stray Kids' momentum from their record-breaking Billboard 200 debut continues at home. "THIS & THAT," which hit No. 1 stateside earlier this month, has now earned a Circle Million certification in South Korea, marking over one million copies sold domestically.

The certification underscores the album's dual success: dominating the U.S. market while simultaneously resonating with Korean listeners. It's a rare position that reflects the group's growing crossover appeal.

Stray Kids weren't alone in earning certifications this week. RIIZE secured a Circle Million certification, as did BOYNEXTDOOR, whose debut album earned the major milestone. TREASURE, ATEEZ, and NewJeans also received recent certifications across physical albums and digital releases. CORTIS and Hearts2Hearts rounded out the latest batch of artists hitting platinum and million thresholds.

These certifications matter beyond numbers. Circle (formerly Gaon) trackers South Korean sales and streaming officially, making certifications the country's standard for measuring commercial success. A million certification means an album or single has genuine, sustained demand in its home market—not just chart placement.

For Stray Kids specifically, the circle certification validates what their Billboard performance already suggested: "THIS & THAT" is connecting with audiences globally. The group spent months building anticipation with teasers and pre-release content, and both markets rewarded that effort.

NewJeans' certification is particularly notable given the group's continued output and fanbase engagement despite ongoing legal disputes surrounding their label. ATEEZ and TREASURE, both known for strong fanbases, continue to maintain reliable sales numbers that keep them in certification conversations.

With several major releases still on the horizon through the fall, certification announcements like these will likely continue rolling in as groups reap the rewards of recent comebacks.
