Firmus has secured full commitments for a $2 billion strategic equity investment, pushing its post-money valuation above $10.5 billion. The raise nearly doubles the company's valuation from the $5.5 billion level recorded in its April financing and brings total equity raised over the past year to more than $3 billion.

The round drew continued participation from existing backers NVIDIA and Coatue, alongside new capital from funds managed by Blackstone Tactical Opportunities and other Blackstone vehicles, plus Jane Street. Proceeds will accelerate Project Southgate, Firmus' multi-site AI Factory program across Australia, and support early expansion into Asia-Pacific markets, including Indonesia.

Capital Deployment and Project Southgate

Firmus plans to direct the fresh capital toward faster rollout of Australian AI Factory sites and preparatory work on regional projects. The company has already secured a multi-year agreement for approximately 18,400 NVIDIA GB300 GPUs at its Melbourne facility with a global technology firm. Additional Australian sites remain under development.

The firm builds its systems on NVIDIA's DSX AI Factory Reference Architecture combined with its proprietary HyperCube platform. HyperCube integrates computing, advanced cooling, power management and grid-aware software to improve efficiency, measured in tokens per watt, and system resilience. Firmus has established domestic manufacturing capacity in Australia for cooling systems, power components and integrated modules to support faster deployment and reduce reliance on imports.

Australia will remain the primary focus for the majority of the new capital. Firmus noted that its existing production capability and software platform enable quicker domestic deployments before broader regional growth proceeds. Early development work has begun on an Indonesian project aimed at AI-native customers.

Investor Backing and Strategic Partnerships

Blackstone's involvement marks a significant institutional commitment to physical AI infrastructure. Coatue increased its stake following earlier support, while Jane Street joined as a new participant.

Firmus and NVIDIA deepened their commercial relationship in late June through an agreement under which Firmus purchases NVIDIA infrastructure and delivers cloud services powered by the chipmaker’s technology. NVIDIA’s renewed equity participation extends that partnership.

The company confirmed the transaction is a private financing and not a public securities offering. Securities issued in the round have not been registered under the U.S. Securities Act of 1933.

Transition from Bitcoin Mining and Industry Context

Firmus began by specializing in cooling technologies for Bitcoin mining infrastructure before shifting to high-performance AI computing facilities. The transition follows a broader pattern among former mining operators that are converting power, cooling and site assets to support AI workloads, which require specialized hardware and network design beyond traditional mining setups.

Similar moves by other companies include capacity agreements and acquisitions aimed at AI data center development. Demand for physical AI infrastructure continues to attract institutional capital as processing requirements for training and inference grow.

Energy and Regulatory Considerations

Rapid expansion has drawn attention to power and water needs. Proposed facilities in Tasmania could require more than 400 megawatts of electricity, prompting community and policy questions about usage at scale. Australian regulations increasingly require data centers to draw majority power from renewable sources, adding requirements around energy sourcing and grid stability.

Firmus stated that its facilities are designed to use renewable energy and participate actively in the power grid. Execution on efficiency and renewable commitments will influence the company’s ability to meet institutional demand while managing resource intensity.

The $2 billion raise positions Firmus among a smaller group of AI infrastructure providers securing large-scale institutional backing as computing capacity remains a priority for technology and investment firms.
