Nvidia-backed Firmus raises $2bn more, doubling its value to over $10.5bn

The money keeps pouring into AI infrastructure, and Firmus is the latest to catch a torrent of it. The Australian data-centre builder has raised a fresh $2bn in strategic equity, fully subscribed, in a round that values the company at more than $10.5bn.

That is roughly double where it stood just four months ago, a pace that captures how fast capital is now chasing AI capacity.

The backer list reads like a who’s who of the moment. Coatue and Nvidia returned as follow-on investors, joined this time by new money from Blackstone’s Tactical Opportunities arm and the trading firm Jane Street.

Nvidia’s presence is the most telling of the four, since the chipmaker rarely invests without strategic intent, and its continued backing ties Firmus tightly to the hardware and reference designs sitting at the centre of the AI build-out.

What Firmus is building, in its own words, are AI factories. The new capital will accelerate its Project Southgate rollout across Australia and fund expansion into the wider Asia-Pacific region, including a new development in Indonesia.

Its pitch leans heavily on efficiency, because the company builds around Nvidia’s reference architecture using its own HyperCube platform and grid-aware software, emphasising energy efficiency and renewable power in a business notorious for its appetite for both.

This round caps a frantic year. Firmus has now pulled in more than $3bn in new equity over the past twelve months, a fundraising tear that few infrastructure startups anywhere can match.

It builds on earlier groundwork too, since in the spring the company raised $505m and lined up a large Blackstone debt facility while preparing a planned ASX listing, and this latest raise simply extends that momentum.

The appetite is less unique to Firmus than a symptom of a wider land grab. Investors are racing to fund the physical layer of AI, and big financiers like Blackstone are pouring into data-centre and cloud ventures at a remarkable clip.

The economics can be lucrative once a builder proves itself, since specialist AI cloud providers have found willing lenders and customers alike, and CoreWeave’s falling borrowing costs show how quickly the market can reward a credible operator.

Underpinning all of it is demand from the giants. Hyperscalers keep signing enormous deals, such as Meta’s multibillion-dollar CoreWeave commitment, which gives infrastructure firms the kind of revenue visibility investors crave.

There is risk baked into the boom, even so. Doubling a valuation in four months assumes AI demand keeps climbing, and any slowdown would hit the most capital-intensive players hardest.

Firmus is geographically concentrated on top of that, since its bet on Australia and Asia-Pacific is really a wager that the region becomes a serious AI hub rather than a bystander to the US-and-China build-out.

The sustainability angle is central to the pitch, and it may prove commercially shrewd rather than merely virtuous.

Firmus emphasises energy efficiency and renewable power in direct response to the mounting criticism that AI data centres devour electricity and water at unsustainable rates, so as governments tighten scrutiny of data-centre power and water use, an operator that can credibly claim efficiency may find it easier to win approvals and customers.

The company’s ambitions ultimately stretch to the public markets. Firmus has signalled plans for an eventual ASX listing, and rounds like this one help build the scale and story that a successful float would require.

Its rise also puts Australia on the AI-infrastructure map, because a homegrown builder attracting Nvidia, Coatue and Blackstone is a signal that the region intends to host serious AI capacity rather than rent it from abroad.

For now, at least, the market is voting with its wallet. A fully subscribed $2bn round at a doubled valuation says investors see Firmus as a real contender in the global scramble to build the machines that run AI.
