Blackstone's AirTrunk seeks $3bn loan for massive Sydney data center

WireByte Staff · June 18, 2026

Blackstone-backed AirTrunk is reportedly seeking approximately $3 billion in debt financing for a new hyperscale data center in Sydney, Australia. The facility, dubbed SYD3, will exceed 400 megawatts in capacity, highlighting the immense power demands of AI infrastructure and the growing financial scale of such projects.

Key points

  • Blackstone-owned AirTrunk is negotiating a debt facility of around A$4.3 billion (roughly $3 billion).
  • The funding is intended for the construction of a single hyperscale data center, SYD3, in Sydney.
  • SYD3 is designed to have a capacity exceeding 400 megawatts, indicating significant power requirements.
  • The loan size reflects the substantial capital investment needed for AI-driven data infrastructure.
  • The project's scale draws attention to the strain on power systems supporting the AI boom.

Blackstone-owned data center operator AirTrunk is reportedly in discussions with banks to secure a substantial debt package valued at approximately A$4.3 billion, which equates to about $3 billion. This financing is earmarked for the development of a new hyperscale data center in Sydney, Australia, identified as SYD3.

The planned facility is expected to surpass 400 megawatts in capacity. This immense power requirement underscores the growing operational scale and energy demands associated with the ongoing artificial intelligence boom. The sheer size of the potential loan is comparable to financing for major public infrastructure projects, signaling the increasing financial muscle behind global data center expansion.

The facility's considerable energy appetite is likely to attract scrutiny from grid operators and local communities concerned with power supply and infrastructure. This situation highlights a critical tension within the technology sector: the rapid influx of capital for AI compute capabilities versus the physical limitations of existing power systems, with Sydney emerging as a key location in this challenge.
