Five Singapore Firms Account for 98% of Southeast Asia Data Center Funding as Build-Out Spreads

Five Singapore-based firms control nearly all of the equity funding for Southeast Asia's data center expansion, despite physical infrastructure being built across neighboring countries. Singapore is the primary source of capital, raising about $11.5 billion for data center companies, with DayOne leading with $6.4 billion. Other major players include Princeton Digital Group, ST Telemedia Global Data Centres, Singtel's Nxera, and Digital Edge.

The concentration of funding highlights Singapore's role as a financing and corporate hub, even as operators add capacity in Indonesia, Malaysia, and other regional markets.

Data center companies raised roughly $11.5 billion across 19 equity rounds up to August 2025, with 85% of the capital pouring in from early 2024 onwards. 2026 became the region's largest funding year on record, with $4.7 billion raised through August 25. DayOne's $4.5 billion Series C accounted for about 96% of that amount, supporting expansion in multiple markets.

Singapore is also building capacity under tighter energy efficiency requirements, with its second Data Centre Call for Application providing at least 200 MW of capacity to qualifying projects. Operators in Indonesia, such as Princeton Digital Group and Digital Edge, are expanding their AI data center footprint, with Princeton breaking ground on a $1 billion, 120 MW campus in Jakarta and Digital Edge reaching the structural topping-out stage on its planned 500 MW campus in Bekasi.

Batam is also attracting AI infrastructure investment, with Firmus Technologies planning a 360 MW Nvidia-powered data center.

However, Singapore's dominance in equity funding does not directly translate into dominance of new physical capacity. Enterprises planning regional cloud or AI deployments will need to consider where operators can secure power and bring new capacity online, which is increasingly happening in markets like Indonesia and Malaysia.
