K-pop group BigBang announced their 2026 reunion world tour, scheduled to begin August 21, 2026, with shows across Asia, North America, Europe, and Australia [1, 2]. The tour marks the 20th anniversary of BigBang's debut in 2006 [3, 2].

BigBang will perform in Singapore at the National Stadium on October 17, 2026, as part of the tour [1, 3]. Besides Singapore, the tour includes other Southeast Asian stops in Vietnam, Thailand, Malaysia, and Indonesia [3]. The full tour features 31 stadium shows planned worldwide [2].

The current lineup includes G-Dragon, Taeyang, and Daesung. Former members Seungri and TOP will not participate [1, 3, 2]. Reports differ on when TOP left the group, with one source saying he departed after the 2022 single "Still Life," while another says he left in 2023 [1, 3].

BigBang reunited about two years ago to perform at Taeyang’s solo concert. Since then, they have appeared at major events, including the 2024 MAMA Awards and 2026 Coachella [1, 2]. At Coachella, G-Dragon said, "This is just the beginning. We got something special to announce for the first time right here at Coachella. BIGBANG's 20th anniversary world tour will begin this August. It's going to be crazy. Do not miss out" [2].

Ticket prices and sale dates for the tour, including Singapore, have not been announced yet [1, 3, 2].

The 20/26 World Tour will officially kick off on August 21, 2026, at Goyang Stadium in South Korea [2]. The Singapore concert will be one of the key dates during the group’s celebration of two decades since debut.
