DayOne, a Singapore-headquartered data center operator, is considering a dual initial public offering (IPO) in both Singapore and the United States as of May 17, 2026 [1, 2, 3, 4, 5]. The company initially planned to list solely in New York but Singapore stock exchange officials persuaded it to pursue a co-listing [1, 2, 3, 4, 5].
The dual IPO aims to raise approximately US$5 billion (about S$6.4 billion), with the company potentially valued around US$20 billion at the time of listing [1, 2, 3, 4, 5]. However, plans for the Singapore listing are not yet concrete as of today [2, 4, 5].
DayOne completed over US$2 billion in Series C funding in January 2026. The round was led by investment firm Coatue Management and included Indonesia's sovereign wealth fund [1, 2, 4]. Other prominent investors include SoftBank Vision Fund and Ken Griffin, founder of Citadel Securities [2, 4].
The company operates data centers across multiple Asia-Pacific and European locations, with its headquarters in Singapore [1, 2, 3]. Formerly known as GDS International, a Singapore subsidiary of China's GDS Holdings, DayOne rebranded in January 2025 after separating from its parent company [2, 3, 4].
In related expansion efforts, DayOne plans to invest over RM28 billion in Malaysia by the end of 2026. The company aims to train more than 1,000 data center engineers focused on AI infrastructure in the country [1].
The coming months will likely determine the formal IPO timetable and whether the Singapore co-listing will materialize alongside the planned US listing.
