DayOne Data Centers Ltd is considering upsizing its Series C funding round to more than $4 billion amid robust investor demand linked to AI-related infrastructure, according to reports from May 14, 2026 [1, 2]. This would nearly double the size of its previous Series C round, which closed in January 2026 at over $2 billion and was led by Coatue Management [1, 2].

The upsized round is expected to be driven mainly by existing investors, including major backers GDS Holdings Ltd, Boyu Capital, Hillhouse Investment, SoftBank Vision Fund, Tekne Capital, Baupost Group, and Citadel CEO Ken Griffin [2]. Data center stocks have surged on public markets in 2026 as AI further drives demand for infrastructure services [2].

DayOne operates data centers across Asia and Europe with facilities in Singapore, Malaysia, Indonesia, Thailand, Hong Kong, Tokyo, and Finland, positioning it well to benefit from regional growth in AI-driven services [2].

Earlier this year, DayOne was close to filing confidentially for a U.S. stock exchange listing but has shifted focus to closing the upsized Series C funding round before setting a timeline for any public share sale [2]. The company is also considering a potential dual listing in both the U.S. and Singapore to broaden investor access [2].

In parallel, DayOne is in talks with banks for about $1 billion in revolving credit facilities to support expansion plans beyond the equity raise [2]. The expanded Series C round valued at approximately $4 billion would equate to around RM 15.7 billion in Malaysian ringgit [2].

The next concrete step for DayOne will be finalizing the upsized Series C round, which remains in progress ahead of any decisions on public listing schedules and credit arrangements.
