June 2026 was one of the most crowded months on South Korea's Circle Chart in recent memory, with a girl-group reunion, a million-selling album debut, and a BTS solo track all landing at No. 1 in different categories within weeks of each other.
What Circle Chart Showed in June 2026
Circle Chart — South Korea's official national music chart, launched as Gaon on February 23, 2010 and rebranded Circle in July 2022 — recorded several distinct weekly No. 1s across its Digital, Album, and Global K-pop rankings in June 2026. Two results stand out as fully cross-verified: TREASURE's fourth mini album [NEW WAV] debuted at Album Chart No. 1 with 1,001,974 first-week distribution copies for the week ending June 6, 2026 , and I.O.I's reunion single "Suddenly" held the Digital Chart No. 1 for three consecutive weeks.
"Suddenly" peaked in Week 25 (June 14–20) with a Digital Chart score of 19,892,542 points, its third straight week on top . That same tracking week saw BTS's "SWIM" lead the Global K-pop Chart, while RIIZE and NMIXX took additional weekly category wins — RIIZE on the Album and Download charts, NMIXX on the Retail Album Chart .
One caveat frames everything below: as of July 1, 2026, Circle had not yet published its official June monthly results. The chart's Digital, Download, and Album pages still displayed "2026 Weeks 25" rather than a finalized monthly table . Every figure in this recap therefore reflects weekly rankings only; the monthly crowns for these acts remain pending Circle's official release.source
I.O.I's 'Suddenly' — Three Straight Weeks at Digital Chart No. 1
The clearest weekly story of the month belonged to I.O.I. The group's reunion single "Suddenly" reached No. 1 on Circle's Digital Chart for the tracking week ending June 6 and held that position through the June 13 and June 20 windows — three consecutive weeks and the longest digital run any release managed in June 2026 . The Digital Chart is Circle's composite ranking, combining streaming, downloads, background music (BGM), and V Coloring sales, so a multi-week hold there signals broad, sustained consumption rather than a single-format spike .
The point totals underline how steady the run was. In Week 24 (June 7–13), "Suddenly" posted roughly 20.8 million Digital Chart points . The following Week 25 (June 14–20) it recorded 19,892,542 points — its third straight week at the top of the chart .source
Week 25 was also where "Suddenly" produced its most complete showing. The single simultaneously led five Circle categories in that single tracking week:
- Digital Chart
- BGM Chart
- V Caller Ring
- Ringtone
- Dial Tone
That five-category alignment in one week was the strongest single-week performance by any act in June, spanning both the composite digital ranking and the older telephony-linked charts that Circle still tracks .
The context makes the result more notable. I.O.I was originally an 11-member project group formed through the first season of Produce 101, active only from 2016 to 2017 before its scheduled disbandment; "Suddenly" is a 2026 reunion release, nearly a decade later . A comeback single sitting atop the Digital Chart for three weeks in a release calendar crowded with new mini albums points to durable fan demand rather than a launch-week bump.
"I.O.I's five-category lead in Week 25 was the most decisive weekly result of the month, with 'Suddenly' holding the Digital Chart for a third straight week," per Circle Chart Week 25 coverage (source: Zapzee).
TREASURE's [NEW WAV] Crosses One Million First-Week Sales
TREASURE's fourth mini album [NEW WAV] opened at No. 1 on the Circle Album Chart with 1,001,974 distribution copies in its debut tracking week, the week ending June 6, 2026. Crossing one million copies in a single week is a commercial milestone that K-pop sales tracking commonly uses to mark a top-tier release, and TREASURE cleared it on the strength of first-week shipments alone .
The figure needs one label to read it correctly. The Circle Album Chart ranks 100 positions by album distribution (shipment) volume — copies moved from labels into the retail pipeline — while the separate Retail Album Chart ranks 50 positions by point-of-sale purchases . TREASURE's 1,001,974 is a distribution number, which is why it is not directly comparable to smaller retail tallies from the same month.
June's album race stayed close after that. RIIZE's II – The 2nd Mini Album topped the Week 25 Album Chart at 984,175 copies for that edition, roughly 1,357,383 once its CD, SMC, and Nemo versions are combined, while NMIXX led the Week 25 Retail Album Chart with 143,094 retail copies of its fifth mini album Heavy Serenade . Two separate acts clearing the million mark within weeks of each other shows how crowded the physical-album field was.source
| Act / Release | Chart | Figure | Week |
|---|---|---|---|
| TREASURE — [NEW WAV] | Album Chart (distribution) | 1,001,974 copies | Ending Jun 6 |
| RIIZE — II | Album Chart (distribution) | 984,175 (~1,357,383 all formats) | Week 25 |
| NMIXX — Heavy Serenade | Retail Album Chart | 143,094 retail copies | Week 25 |
Read together, the distribution and retail figures make the same point from two angles: demand for physical K-pop albums held firm across June, and TREASURE's debut week sat at the top of the shipment-based ranking that most sales headlines cite .
BTS, RIIZE, and NMIXX: Other Weekly Winners in June
Three more acts claimed weekly Circle Chart crowns during Week 25 (June 14–20, 2026), which is why June ranks among the most competitive months of the year. BTS held the Global K-pop Chart with "SWIM," a sustained multi-week run through June; RIIZE won both the Album Chart and the Download Chart; and NMIXX led the Retail Album Chart with its fifth mini album Heavy Serenade .source
RIIZE's II – The 2nd Mini Album topped the Week 25 Album Chart with 984,175 copies for that edition — roughly 1,357,383 across the CD, SMC, and Nemo formats — while the group's track "Do your dance" won the weekly Download Chart . That distribution figure sat just under TREASURE's million-copy debut, meaning two acts approached or passed the one-million album threshold in overlapping June tracking weeks.
NMIXX's Heavy Serenade led the Week 25 Retail Album Chart with 143,094 retail-store copies, or about 163,200 across the CD and POCA versions . The Retail Album Chart ranks 50 positions by retail-store sales, a narrower measure than the shipment-based Album Chart that most sales headlines cite, so the retail and distribution numbers describe physical demand from two different angles.
On the digital side, BTS's "SWIM" kept the Global K-pop Chart through Week 25 as part of a multi-week run . Taken together, four separate chart families — Album, Retail Album, Download, and Global K-pop — went to four different acts in a single week, underlining how crowded the June release calendar became.
Monthly Chart Status: What's Official and What's Still Pending
Circle's monthly June 2026 tables were not yet published as of July 1, 2026. On that date, the official site at circlechart.kr still displayed "2026 Week 25" weekly data across its Digital, Download, and Album pages as the latest available update, with no finalized June monthly results table live yet . In practice, a June monthly chart takes additional weeks to close, so early July is too soon to treat any June monthly crown as confirmed.
That timing gap matters for the monthly attributions now circulating in secondary coverage. ZEROBASEONE and ILLIT monthly-win claims that appear in some K-pop reports cannot be verified against Circle's primary pages at this stage . Similarly, some briefs list CORTIS's "GreenGreen" and AKMU's "Paradise of Rumors" as June monthly leaders, but the primary-adjacent record places those exact titles as May 2026 monthly leaders — with "GreenGreen" logging 1,695,155 monthly album sales in May — rather than June . Until Circle posts the June set, those items are best read as provisional.
For readers who want the authoritative version, the fix is straightforward: once published, official June monthly results appear at circlechart.kr under the Monthly view for each chart family — Digital, Album, Global K-pop, and others — where several families already offer Monthly, First Half, and Yearly tabs alongside Weekly .
The concrete takeaway: June 2026's verified story is a weekly one. I.O.I's "Suddenly" and TREASURE's [NEW WAV] hold firm, cross-checked weekly No. 1s; the five-act monthly slate stays pending until Circle's official June tables go live.

Did ZEROBASEONE or ILLIT win any June 2026 Circle Chart categories?
Monthly win attributions for ZEROBASEONE and ILLIT are circulating in secondary K-pop coverage , but they are not yet confirmed by Circle's primary pages, which still displayed Week 25 data rather than a finalized June monthly table as of July 1, 2026 . The official June monthly publication will clarify these claims.
What is the difference between the Circle Album Chart and the Retail Album Chart?
The Album Chart ranks 100 positions by distribution (shipment) volume sent to retailers and distributors, while the Retail Album Chart ranks 50 positions by actual in-store sales . Because the two use different methods, an album can rank differently on each. In June 2026, TREASURE led distribution with 1,001,974 copies, while NMIXX's Heavy Serenade topped the Week 25 Retail Album Chart with 143,094 retail copies .
