Firmus Secures $10 Billion Blackstone-Led Debt for Australia AI Data-Center Buildout

The private financing backs Project Southgate’s plan to scale energy‑efficient AI factories to 1.6 GW by 2028 on Nvidia’s DSX architecture.

Overview

  • The facility is led by Blackstone Tactical Opportunities and Blackstone Credit & Insurance with support from Coatue Management, and is described as among Australia’s largest private debt deals.
  • Proceeds will accelerate the national rollout of Firmus’s AI Factory platform, with sites already under construction across multiple Australian locations.
  • Project Southgate targets 1.6 gigawatts of compute capacity and the deployment of thousands of GPUs in Australia by 2028.
  • Firmus’s platform is built on Nvidia’s DSX reference architecture and includes a partnership with CDC Data Centres to serve hyperscale and AI-native customers.
  • The package follows $582 million in prior equity backing from Nvidia and Ellerston Capital, with Firmus planning an ASX listing later in 2026 after a reported $6 billion valuation in November.
