Once completed, AirTrunk’s total portfolio in Malaysia is expected to exceed 700MW of IT capacity, supported by total investment of approximately $6.8 billion
In sum – what to know:
Capacity expansion – Two new campuses will add over 280MW, reinforcing Johor as a key regional data center hub.
AI-driven growth – Investment reflects rising demand for AI and cloud infrastructure across Southeast Asia.
Portfolio scaling – AirTrunk’s Malaysia footprint is set to exceed 700MW with total investment reaching $6.8 billion.
AirTrunk is expanding its presence in Malaysia with plans to invest $3 billion in two new data center campuses in Johor, further scaling its regional capacity to support growing demand for cloud and AI infrastructure.
The new facilities, JHB3 and JHB4, will be located in Iskandar Puteri, close to the company’s existing JHB1 and JHB2 sites. Together, they are expected to deliver more than 280MW of IT capacity and will use recycled water for cooling.
“JHB3 and JHB4 represents the next phase of our expansion in Malaysia, building on the strong momentum of our existing Johor platform. Malaysia has set a clear ambition to lead in AI, and we’re investing in that vision for the long term, both within Johor and across the country in time,” said Robin Khuda, founder and chief executive officer at AirTrunk.
The expansion builds on AirTrunk’s earlier developments in Johor. The JHB1 campus, launched in 2024, currently provides more than 50MW in its initial phase, with over 150MW planned at full build-out. The company also announced the 270MW JHB2 facility in early 2025.
Once completed, AirTrunk’s total portfolio in Malaysia is expected to exceed 700MW of IT capacity, supported by total investment of approximately $6.8 billion.
Johor has emerged as a key data center hub in Southeast Asia, benefiting from its proximity to Singapore. As capacity constraints and regulatory limits have slowed new developments in Singapore, operators have increasingly turned to Johor as an alternative location for large-scale projects.
“Malaysia’s recent boom in data center and AI infrastructure investment around Kuala Lumpur and Johor is being driven by a mix of demand-side growth, strategic location advantages, supportive public policy, and competitive economics — making the country an attractive hub for hyperscale cloud, AI and digital infrastructure across Southeast Asia,” Jabez Tan, head of research at Structure Research, previously told RCRTech.
Founded in 2018, AirTrunk operates and develops data centers across key Asia-Pacific markets, including Australia, Singapore, Hong Kong, Japan, and Malaysia. The company was acquired in 2024 by Blackstone and Canada Pension Plan Investment Board in a $16.1 billion transaction.
AirTrunk has recently entered the Indian data center market through the acquisition of Lumina CloudInfra, securing immediate access to one of the fastest-growing hubs for AI and cloud infrastructure globally.
The deal provided AirTrunk with Lumina’s approximately 600MW development pipeline, alongside existing contracts, local relationships and operational capabilities. The portfolio represents up to $5 billion in potential future investment, according to AirTrunk.
