AirTrunk

AirTrunk is an Australian-founded data centre infrastructure company established in 2015 by Robin Khuda and headquartered in Sydney. It develops, owns and operates hyperscale data centre campuses serving cloud service providers, internet businesses and large enterprises. Rather than selling consumer technology products, AirTrunk provides the physical infrastructure required to run digital services at scale, including data centre space, electrical capacity, cooling, connectivity, security and operational support. The company was created during a period of rapid growth in cloud computing, online services, enterprise digitisation and data-intensive applications. Its business model is based on developing large campuses that can be expanded in stages as customers require additional capacity. This approach allows cloud and enterprise customers to secure substantial power and technical space while using a professionally operated facility instead of building and managing all of the infrastructure themselves. AirTrunk initially focused on Australia and subsequently expanded across the Asia-Pacific region. Its stated operating footprint covers Australia, Singapore, Japan, Malaysia, Hong Kong and India. Reference material describes more than 3 gigawatts of operating and planned capacity across 20 sites in those six markets. The portfolio includes facilities in major digital hubs such as Tokyo and Osaka. In Japan, AirTrunk has four hyperscale campuses—TOK1, TOK2, OSK1 and OSK2—with approximately 530 megawatts of combined potential capacity at full build-out. TOK1, in the eastern Tokyo area, is designed to scale beyond 300 megawatts. AirTrunk's expansion has required large-scale project finance, land development, energy procurement, engineering and long-term customer planning. In March 2026, the company secured a ¥191.6 billion green loan to refinance existing facilities and support additional TOK1 development phases. The financing was described as the largest data centre financing completed in Japan and was arranged under AirTrunk's Green Financing Framework. In April 2026, AirTrunk announced the acquisition of Lumina CloudInfra, a Blackstone-founded data centre developer, to expand its Indian platform. Lumina was reported to have 600 megawatts of planned capacity and development potential of up to US$5 billion, although the transaction value was not disclosed. AirTrunk was sold to Blackstone for A$24 billion, reported as approximately US$16 billion. Following the transaction, AirTrunk remained a privately held infrastructure business rather than a publicly listed company. Public disclosures provide useful information about its geographic expansion, campuses and financing activities, but do not establish a complete customer list, detailed annual financial performance or the full operational status of every planned facility. The company is best understood as a regional hyperscale data centre platform whose competitive proposition is based on scale, development capability, power availability, connectivity and the ability to support major digital customers across Asia-Pacific.

AirTrunk was founded in Australia in 2015 by Robin Khuda and established its headquarters in Sydney. From the beginning, the company concentrated on hyperscale data centre infrastructure rather than consumer-facing technology products. Its facilities are designed for cloud service providers, internet businesses and large enterprises that need substantial, reliable and expandable supplies of power, technical space, cooling and network connectivity. The company's development model is based on large campuses that can be delivered in stages. This model supports the rapid growth of digital workloads while allowing customers to expand their requirements over time. It also places significant emphasis on site selection, access to electricity, network connectivity, construction capability and long-term facility operations. AirTrunk's activities therefore combine real-estate development, infrastructure investment, engineering and specialist data centre management. After establishing its Australian platform, AirTrunk expanded into other Asia-Pacific markets. Reference material identifies operations or planned developments in Australia, Singapore, Japan, Malaysia, Hong Kong and India. Across these markets, the company is described as having more than 3 gigawatts of operating and planned capacity distributed across 20 sites. The regional strategy reflects the concentration of cloud, internet and enterprise demand in major Asian digital hubs, as well as the need for data centre operators to provide capacity close to users and network exchanges. Japan became one of AirTrunk's important development markets. The company has four hyperscale campuses there: TOK1 and TOK2 in the Tokyo area and OSK1 and OSK2 in Osaka. At full build-out, the four campuses are expected to provide approximately 530 megawatts of total capacity. TOK1, located in eastern Tokyo, is planned to scale beyond 300 megawatts and represents the type of very large campus on which AirTrunk's operating model is based. AirTrunk's projects require substantial financing because hyperscale facilities involve major land, construction, electrical and mechanical infrastructure commitments. In March 2026, the company secured a ¥191.6 billion green loan connected with TOK1. The financing was intended to refinance existing facilities and support further development phases. It was structured under AirTrunk's Green Financing Framework and led by Sumitomo Mitsui Banking Corporation, MUFG Bank, Crédit Agricole CIB and Société Générale as global coordinators, with twelve banks participating. The transaction was described as the largest data centre financing completed in Japan. India became a further area of expansion in April 2026, when AirTrunk announced the acquisition of Lumina CloudInfra. Lumina had been founded by Blackstone and was reported to have 600 megawatts of planned capacity and up to US$5 billion in development potential. The purchase price was not disclosed. The transaction illustrates AirTrunk's use of acquisitions alongside organic campus development to build regional capacity. AirTrunk was sold to Blackstone for A$24 billion, reported as approximately US$16 billion. The sale made Blackstone the company's owner and placed AirTrunk within Blackstone's infrastructure investment portfolio. AirTrunk remained a private company, so detailed information about revenue, profitability, customers and project-level operating performance is limited. Publicly available material nevertheless establishes a clear trajectory: the business began as an Australian hyperscale data centre developer, expanded into a multi-market Asia-Pacific platform, and grew through a combination of campus development, project finance and corporate transactions.
