According to United Overseas Bank (UOB) executives speaking at the ASEAN Conference 2026, artificial intelligence has evolved beyond a technology story in Southeast Asia to become an economic growth engine. The opportunity lies less in adopting AI tools than in building the physical infrastructure that enables them. As reported by UOB, this infrastructure development represents a fundamental shift in how the region approaches AI adoption and economic development.
The scale of AI infrastructure development in Southeast Asia is projected to be substantial. Wood Mackenzie estimates data-center power demand could quadruple from 2.6 gigawatts in 2025 to 10.7 gigawatts by 2035. Additionally, the e-Conomy SEA 2025 study by Google, Temasek, and Bain estimates over 4,600 megawatts of new capacity in the pipeline, implying roughly 180% capacity growth, faster than the rest of Asia-Pacific. According to UOB's Edmund Leong, roughly $150 billion could flow into regional energy infrastructure over the next five years to support this expansion.
The infrastructure build-out spans multiple markets with varying challenges. Malaysia has captured much of the recent growth, while Thailand, Indonesia, and Vietnam are also expanding aggressively as investment spreads across the region. However, Singapore faces different constraints including land and energy limitations that have prompted spillover effects on neighboring markets. As reported by UOB, the build-out demands more than servers and chips, requiring reliable power, advanced cooling, land, and robust grid connections, with capital requirements correspondingly large.
The potential economic impact of AI infrastructure development is substantial. Southeast Asia's digital economy should exceed $300 billion in gross merchandise value, with AI potentially adding up to $1 trillion to regional GDP by 2030. Funding patterns reveal an interesting geographic split, with equity concentrating in Singapore while physical construction is dispersed, with Malaysia alone attracting tens of billions in commitments. According to UOB, financial institutions with regional footprints play a pivotal role in mobilizing loans, bonds, and equity while facilitating cross-border capital flows.
