AirTrunk Doubles Down on Johor with RM12 Billion Data Centre Expansion
AirTrunk is going even bigger in Malaysia.
The Australia-founded hyperscale data centre giant has announced a fresh RM12 billion investment into Johor, adding two new large-scale campuses that will significantly expand its presence in the country. The move strengthens Johor’s position as one of Southeast Asia’s fastest-growing digital infrastructure hubs.
The two new campuses, known as JHB3 and JHB4, will be built in Iskandar Puteri, right next to AirTrunk’s existing JHB1 and JHB2 facilities. Together, the new sites will add over 280 megawatts (MW) of IT capacity, bringing AirTrunk’s total planned capacity in Malaysia to more than 700MW across four campuses.
That’s a massive jump — and a clear sign that Johor is becoming a serious player in Asia’s data centre race.
Why Johor?
Johor’s rise as a digital hotspot isn’t accidental.
Its biggest advantage remains geography. Sitting just across the border from Singapore — one of Asia’s most mature cloud and financial hubs — Johor offers cheaper land, lower operating costs, and growing power infrastructure.
Singapore has also tightened data centre approvals over the past few years due to land and energy constraints, pushing hyperscale operators to look nearby. Johor has become the obvious answer.
That shift has accelerated with the rise of artificial intelligence.
AI workloads require far more computing power than traditional cloud services, which means bigger facilities, higher-density servers, and more advanced cooling systems.
That’s exactly what AirTrunk is building.
Built for AI, Not Just Cloud
Unlike older-generation data centres, JHB3 and JHB4 are specifically designed for high-density AI computing.
AirTrunk says the new campuses will use cooling systems powered by 100% recycled water, a major sustainability move as concerns over data centre water consumption continue to grow.
This matters because AI servers generate much more heat than standard cloud systems. Cooling efficiency is now becoming just as important as computing power.
AirTrunk says these sites will operate at lower power usage effectiveness (PUE) than traditional facilities, making them more efficient overall.
Malaysia’s Total AirTrunk Investment Hits RM27 Billion
With this new expansion, AirTrunk’s total committed investment in Malaysia now stands at around RM27 billion (US$6.8 billion).
That’s one of the largest hyperscale data centre commitments ever announced in the country.
AirTrunk founder Robin Khuda said the company sees Malaysia as a long-term AI infrastructure market, not just a short-term expansion point.
And this may not be the end.
The company has confirmed it is already evaluating further expansion opportunities beyond JHB3 and JHB4.
More Than Just Servers: Jobs and Local Supply Chain
Beyond infrastructure, the project is expected to bring real economic impact.
Construction of the two campuses is projected to create over 3,000 jobs, while local supplier contracts across AirTrunk’s Johor operations could eventually reach RM5 billion.
So far, AirTrunk says it has already awarded over RM423 million to Malaysian suppliers.
That aligns with Malaysia’s broader push to localise more of the data centre value chain — from engineering and construction to maintenance and operations.
Blackstone’s Bigger Asia Bet
There’s also a larger global strategy behind this.
AirTrunk was acquired in 2024 by a consortium led by Blackstone Inc. and Canada Pension Plan Investment Board in a deal valuing the company at over AUD24 billion.
Since then, AirTrunk has been aggressively scaling across Asia-Pacific, recently expanding further into India while growing its footprint in Japan and Australia.
With the Johor expansion, AirTrunk’s total regional capacity will exceed 3.3 gigawatts across 22 campuses in six markets.
Malaysia’s AI Ambition Is Getting Real
For Malaysia, this isn’t just another foreign investment headline.
It’s part of a much bigger shift.
As the country pushes deeper into AI, cloud services, and digital transformation, infrastructure like this becomes the backbone of that ambition.
Data centres used to be about storage.
Now, they’re about powering the next generation of AI.
And if AirTrunk’s latest RM12 billion move is any sign, Johor is quickly becoming one of the places where that future gets built
