Firmus AI infrastructure funding has put a relatively little-known Australian company at the center of the global compute boom. A multibillion-dollar equity placement involving investors including Nvidia and Blackstone has valued Firmus at about A$15.5 billion, as investors pour increasingly large sums into the physical infrastructure required to run artificial intelligence.
Firmus raise pushes valuation to $15.5 billion
Firmus recently completed an equity placement worth about A$2.9 billion, according to reports on the transaction, with investors including Nvidia, Blackstone, Coatue Management and Maas Group. The deal values the privately held AI infrastructure company at approximately A$15.5 billion.
The distinction between Australian and US dollars matters here. The source material describes the latest transaction as A$2.9 billion and the valuation as A$15.5 billion, rather than a US$2 billion round at a US$10.5 billion valuation. Firmus had already been raising aggressively: in April it announced a US$505 million strategic equity investment led by Coatue with Nvidia participation subject to closing conditions.
AI data centres reshape venture investment
Firmus belongs to a much bigger capital shift. Global startup investment reached a record $510 billion in the first half of 2026, exceeding the $440 billion invested during all of 2025. OpenAI and Anthropic alone accounted for $217 billion, or 43% of the first-half total.
But AI investment increasingly extends beyond software and foundation models. The sector needs GPUs, electricity, cooling, networking and enormous data-centre campuses. Firmus' Project Southgate illustrates this transformation. The company says the Australian project is designed to scale to 1.6 gigawatts, while a separate Nvidia partnership targets a 360 MW AI factory campus containing about 170,000 GPUs in Batam, Indonesia.
Nvidia AI infrastructure strategy expands
Nvidia's involvement is particularly important because the chipmaker is increasingly participating in financing the infrastructure ecosystem that purchases its technology.
On August 10, Nvidia announced partnerships with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR aimed at mobilizing more than $500 billion in third-party capital for AI infrastructure. The initiative is designed to expand access to Nvidia-based computing capacity.
That strategy can accelerate deployment, but it also deserves scrutiny. When a major hardware supplier helps expand financing available to customers building around its technology, hardware demand and infrastructure financing become increasingly interconnected.
Project Southgate shows AI's physical scale
Firmus has already secured a US$10 billion debt financing facility led by Blackstone and supported by Coatue to expand Project Southgate. It has also announced a multiyear customer agreement involving approximately 18,400 Nvidia GB300 GPUs at its Melbourne deployment.
The wider market is moving in the same direction. Meta and BlackRock recently established a venture for an approximately $14 billion, one-gigawatt data-centre campus in El Paso, with BlackRock-managed funds owning 80%.
The central question is therefore shifting. Investors are no longer betting only on which AI model will win. They are placing enormous bets on who will supply the electricity, buildings, cooling and chips needed to keep those models running.
Firmus' rise captures that change: the AI boom is increasingly becoming an infrastructure boom.
