Singapore's DayOne Data Centers Files for US IPO, Targeting a US$5B Raise

Singapore's data centre boom has produced its biggest capital-markets story yet. DayOne Data Centers, the Singapore-based operator founded in 2022, has confidentially filed for a US initial public offering, with people familiar with the matter saying it aims to list as soon as next quarter and raise around US$5 billion at a valuation Bloomberg has previously reported could reach US$20 billion.

The filing caps a remarkably fast rise. In June, DayOne closed a US$4.5 billion Series C led by its biggest shareholders Coatue Management and Hillhouse, joined by new backers Achi Capital Partners and the Indonesian Investment Authority. The company says the funding will accelerate expansion across Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland and Spain, and since inception it has secured more than 1.5GW of booked capacity across Asia Pacific and Europe. Its investor list also includes China's GDS Holdings, SoftBank Vision Fund and Citadel's Ken Griffin.

DayOne is riding a wave that keeps getting bigger. Investor interest in data centres has surged alongside AI compute demand, and the IPO queue is full of infrastructure names — Australia's Firmus Technologies just secured commitments for a US$2 billion round, while Switch and Nscale are among the operators lining up listings. Closer to home, Blackstone-backed AirTrunk filed in July for a S$1.9 billion Singapore REIT IPO on the back of the same boom.

For Singapore, the story carries a double meaning. DayOne is proof that a locally headquartered operator can scale into a global AI-infrastructure player, attracting the same capital that funds Silicon Valley's data centre giants. At the same time, the choice of a US listing over a Singapore one is a familiar reminder that the deepest pools of tech capital still sit across the Pacific — even as Singapore REITs compete for infrastructure investors locally.

Why it matters for Singapore: AI demand is reshaping where the world's compute gets built, and Singapore is one of the main beneficiaries — but its operators increasingly have to look abroad for growth and capital. DayOne's IPO will be a live test of how much the market values a Singapore-based, AI-driven infrastructure franchise, and its result will be read closely by every other local data centre player sizing up the public markets.
