Arena @ Expo is Singapore EXPO's plug-and-play concert hall, a 6,700-seat indoor arena built inside Hall 7 of the Singapore EXPO complex in Tampines. Soft-launched in January 2024 and upgraded again in 2025, it was designed to fill the gap between mid-sized halls and Singapore's stadiums, seating roughly 3,000 to 6,000 in a standard configuration and up to 6,700 at full capacity, with configurations ranging from all-seated theatre style to a mix of seating and standing pens. The modular stage measures 18.3 metres across and 12.2 metres deep, the tiered seating rows are inclined for clearer sightlines, and the hall carries a high-end audio-visual system with a plug-and-play setup and an indoor queueing area for touring productions. Singapore EXPO itself opened in 1999 and is the country's largest purpose-built MICE venue, managed by Constellar. Arena @ Expo has partnered promoters including Live Nation, iMe Entertainment, CK Star Entertainment and Flabbergast Productions, and hosts concerts, fan meets and showcases.
