AirTrunk is an Australian-founded hyperscale data centre developer and operator that builds and leases massive, purpose-built campuses to cloud providers, content platforms and large enterprises across the Asia-Pacific and Middle East. As of 2026 the company operates or has under development more than 20 sites across six countries — Australia, Singapore, Japan, Malaysia, Hong Kong and India — with over 3GW of operating and planned capacity, and it has just begun a Middle East push through a partnership in Saudi Arabia. Founded by Robin Khuda in 2015 and now backed by Blackstone (which acquired it in a landmark A$24 billion deal completed in 2024) and the Canada Pension Plan Investment Board, AirTrunk is distinguished by its “campus style” hyperscale deployment model — huge, carrier-neutral facilities built specifically for single large tenants rather than mixed retail colocation — plus an emphasis on low power-usage-effectiveness design (targeting PUE as low as 1.15) and, increasingly, liquid-cooled, AI/GPU-ready capacity in its newer Japanese, Malaysian and planned Middle Eastern campuses.
AirTrunk has a confirmed data center presence at the following locations:

HKG1 was AirTrunk's first Hong Kong facility, a retrofit of an eight-storey industrial building near Tsuen Wan completed in just over a year and designed to a PUE of 1.35, making it one of the most efficient data centres in Hong Kong. - Navi Mumbai, Maharashtra, India BOM1 Mumbai CARRIER-NEUTRAL PENDING REVIEW
BOM1 sits on a 6.3-acre site in Navi Mumbai's Airoli area and is set to deliver over 60MW of capacity across two phases, entering AirTrunk's portfolio through its 2026 acquisition of Lumina CloudInfra. - Inzai, Japan TOK1 Tokyo East CARRIER-NEUTRAL PENDING REVIEW
TOK1, located in Inzai near Tokyo, is AirTrunk's flagship Japan campus, designed to scale to more than 300MW of capacity and financed in 2026 via a JP¥191.6 billion green loan, the largest data centre financing ever completed in Japan. - Osaka, Japan OSK1 Osaka WestAI DATA CENTER CARRIER-NEUTRAL PENDING REVIEW
OSK1, AirTrunk's first Osaka facility, is a 16,500sqm development in West Osaka with a 20MW capacity dedicated to high-scale cloud requirements. - Tokyo, Japan TOK2 Tokyo West CARRIER-NEUTRAL PENDING REVIEW
TOK2 is scalable to over 110MW and, at its official opening, was described as one of the largest data centres in Japan, complementing TOK1 to give customers location diversity within the Tokyo cloud availability zone. - Johor Bahru, Malaysia JHB1AI DATA CENTER CARRIER-NEUTRAL PENDING REVIEW
JHB1, AirTrunk's first Malaysian data centre, spans 21,900 square metres across 20 data halls with more than 150MW of capacity and uses a combination of indirect evaporative and direct-to-chip liquid cooling to enable high-density AI rack deployments. - Singapore, Singapore SGP1 CARRIER-NEUTRAL PENDING REVIEW
SGP1 was delivered in just over a year and topped out in less than 30 weeks despite the COVID-19 pandemic, with StarHub as its anchor tenant when it launched in Loyang in 2020.
By Continent
AI Data Centers
AirTrunk has been steadily converting several of its newest campuses into AI-ready infrastructure rather than plain hyperscale cloud space. Its Johor Bahru campus in Malaysia (JHB1, and the planned JHB2) uses a combination of indirect evaporative cooling and direct-to-chip liquid cooling specifically so customers can run high-density AI racks, cutting energy use by up to 20% versus air cooling. In Japan, the second Osaka campus (OSK2) was announced explicitly to meet surging cloud-and-AI demand in the Kansai region, and AirTrunk's newly announced Saudi Arabian partnership with HUMAIN is being built from the ground up as GPU-based AI training and inference capacity.

Common Questions
Does AirTrunk have AI/GPU-specific data centre infrastructure?
Yes. Facilities such as JHB1 in Johor Bahru, Malaysia use direct-to-chip liquid cooling combined with indirect evaporative cooling specifically to enable high-density AI rack deployments, and the announced JHB2 and OSK2 (Osaka) campuses are explicitly positioned as cloud-and-AI-ready capacity for AI training and inference workloads.
Who owns AirTrunk?
AirTrunk was founded by Robin Khuda in 2015 and, after an earlier investment from Macquarie, was acquired by Blackstone in a deal valued at roughly A$24 billion (US$16 billion), reported as the largest data centre transaction globally and the largest Australian deal of 2024.
What markets does AirTrunk operate in?
AirTrunk's platform spans Australia, Singapore, Hong Kong, Japan, Malaysia and India, and in 2025 it announced its first move into the Middle East through a partnership with Saudi Arabia's HUMAIN to build data centres in the Kingdom.
Is AirTrunk a colocation or cloud company?
AirTrunk builds and operates hyperscale data centre campuses that it leases to cloud, content and large enterprise customers to house their own infrastructure — a wholesale colocation model — rather than selling cloud compute or storage services of its own.
