Blackstone and Coatue loan $10B to Australian AI infrastructure startup Firmus for data center expansion, in one of the country's largest private credit deals
Australian AI startup Firmus Technologies Pty. secured a $10 billion loan from a group including Blackstone Inc.-led funds …
Context & Ripple Effects
Firmus had already pursued rapid expansion capital, including an earlier AU$500M raise that followed a September round. The $10B private-credit facility gives that buildout a debt-financed leg alongside equity.
The financing also fits Blackstone’s established Australian data-center exposure through its AirTrunk acquisition. Firmus subsequently tied capacity to a multi-billion Melbourne data-center customer agreement, giving the expansion a clearer commercial backdrop.
First-order effects
- Firmus gains a large pool of debt financing for data-center expansion, while Blackstone-led funds and Coatue take on credit exposure to the company’s buildout.
- The deal puts private credit, rather than equity alone, at the center of funding Firmus’s near-term infrastructure plans.
Second-order effects
- Firmus can combine the facility with later equity funding—such as Coatue’s $505M-led round—to finance expansion with a more layered capital structure.
- Other AI-infrastructure developers seeking large facilities may face greater pressure to show credible customer commitments and financing structures that can support large debt packages.
Third-order effects
- If such facilities become repeatable, AI data-center construction will increasingly depend on private-credit underwriting of long-lived infrastructure rather than venture funding alone.
- That can concentrate the market around developers able to secure both major capital partners and demand commitments, while increasing the importance of execution and customer-concentration risk for lenders.
The trend: AI infrastructure is evolving into an asset-finance market in which private credit and equity are jointly funding large-scale compute capacity.
