BIGBANG's 20th Anniversary Single 'BiiiG'
YG Entertainment announced that BIGBANG will release a new single, 'BiiiG', on 19 August 2026 — the group's 20th debut anniversary to the day. It is their first release as a full group in four years and four months, since 'Still Life' era track 'Spring Summer Fall Winter' in April 2022, and will be followed by the 'BIGBANG 2026-2027 WORLD TOUR <XX : COSMOS>'.
The release
YG Entertainment announced on 10 August 2026 that BIGBANG would release a new single, BiiiG, on 19 August 2026 — the group's debut anniversary to the day. The release time was given as 18:00 on 19 August.
It was presented as the group's first single as a full group in four years and four months, since the April 2022 release. BIGBANG debuted on 19 August 2006, so the release date fell exactly on the 20th anniversary.
The title
The title is taken from BIG, and was explained as carrying the identity of the group's name. The agency described the song as showing where BIGBANG stands at its 20th anniversary and as presenting a further musical range.
World tour
The 20th-anniversary world tour BIGBANG 2026-2027 WORLD TOUR <XX : COSMOS> opened with a concert at Goyang Stadium on 21 August, running for three days from 21 to 23 August. It was announced as continuing to 19 cities for 33 shows across North America, Europe, Oceania and Asia.
In the tour title, XX was explained as standing for BIGBANG's twenty years, and COSMOS not as outer space but as a concept of connection, relationship and continuity — described as meaning everything that has existed, exists now and will exist.
It is BIGBANG's first solo world tour in nine years, since the 2017 tour. Domestic ticketing was run only through the Coupang Play mobile app, with fan-club presale on 24 June and general sale on 25 June.
What full group refers to here
The phrase full group attached to this activity means that all three current members — G-DRAGON, Taeyang and Daesung — take part. It does not mean that the five-member line-up of the 2006 debut reassembles.
It is described as the official tour with the three of them together following the change in the group's line-up, and the phrase is used in that sense alongside the fact that it is their first solo tour in nine years. The new single is likewise a release by this three-member line-up.
