Digital Realty Deepens Singapore AI Investment: S$4.3 Billion Bet on Data Infrastructure

Date: April 12, 2026

In a landmark move that underscores Singapore's growing importance in the global AI landscape, Digital Realty has announced plans to invest over S$4.3 billion in new data centre developments in the Lion City. This substantial commitment brings the company's total potential investment in Singapore to nearly S$7 billion, signaling strong confidence in the city-state's role as a regional AI hub.

The AI Inference Boom

For many companies, the next phase of artificial intelligence is no longer about building models, but putting them to work in real-world settings. This phase, known as inference, involves processing real-time data and generating responses for users. Unlike model training, which can often take place in lower-cost locations further from end users, inference typically requires systems to be closer to users and network hubs to minimise delays.

"This shift is creating new demands on digital infrastructure, particularly around connectivity, latency and data governance," said Ms Serene Nah, Managing Director and Head of Asia Pacific at Digital Realty, who was recently recognised in Data Centre Magazine's 2026 Top 100 Women in Data Centres.

Why Singapore?

Singapore is well placed to support companies running AI at scale, thanks to its world-class connectivity and regulatory environment. "Data sovereignty is a real driver, especially for regulated sectors, and it shapes where certain workloads need to sit," explained Ms Nah. "High-value, latency-sensitive inference needs to be located in trusted hubs like Singapore."

The policy landscape is also evolving alongside industry needs. In January 2026, Singapore introduced its Model AI Governance Framework for Agentic AI, providing guidance on the responsible use of enterprise agentic AI systems.

Workforce Development

Digital Realty has almost doubled its local headcount over the past three years and aims to grow its workforce to 400 by 2030. The company takes an "in-country, for-country" approach, with nearly 90 per cent of its Singapore team being local.

The company is investing in workforce development through programmes such as the Institute of Technical Education's Work-Study Diploma and partnerships with institutions including the National University of Singapore. Earlier this year, Digital Realty hosted a Digital AI Open House for students from NUS' Tembusu College.

The Innovation Lab

One challenge for companies expanding AI use is assessing whether their infrastructure can handle complex workloads before committing significant resources. To address this, Digital Realty plans to launch its Digital Realty Innovation Lab (DRIL) in Singapore in the third quarter of 2026 at its Loyang facility.

First introduced in Ashburn, Virginia, in September last year, the lab provides a supported environment to develop, test and run AI and hybrid cloud solutions before scaling them. "With DRIL, we bring together infrastructure components, technology partners and data centre designs so customers can validate what they need before deploying at scale," said Ms Nah.

Sustainability Matters

As AI adoption accelerates, questions remain about how to sustain this growth, particularly in land- and energy-constrained Singapore. Discussions between industry and government—including those linked to the Green Data Centre Roadmap—are focused on improving efficiency and increasing the use of cleaner power.

Digital Realty has achieved 100 per cent renewable energy coverage for its Singapore operations, reflecting its commitment to sustainable growth. The company may lead to a more distributed model, where some workloads are handled in nearby markets while Singapore remains central for latency-sensitive AI and cloud connectivity.

Looking Ahead

Singapore's strength may lie in balancing technological progress with trust, governance and sustainability. As Ms Nah noted, "Success means attracting the right mix of industries and workloads that create long-term value. We help customers deploy AI in ways that are trusted, resilient and sustainable."

With this massive vote of confidence from Digital Realty, Singapore is cementing its position as the de facto AI hub for Southeast Asia—and perhaps beyond.
