Australian AI startup Firmus raises $2 billion backed by Nvidia
A company in Australia named Firmus builds big buildings that hold the computers used for artificial intelligence, also called AI.
These buildings are called data centres, and they use a lot of electricity and special computer chips.
Firmus just received a huge amount of money — $2 billion — to build more of them.
One of the investors is Nvidia, the company that makes many of the computer chips AI needs.
Around the world, investors are pouring more money into tech startups than ever before.
In the first half of 2026, startups raised a record $510 billion.
In all of 2025, they raised $440 billion.
Much of this money is going toward buildings, power, cooling and chips rather than new software.
Some people worry that so much spending might not earn back the money it costs.
If AI turns out to be less useful than expected, some of these huge investments could be risky.
Firmus, an Australian AI infrastructure company, raised $2 billion in equity at a valuation exceeding $10.5 billion, with Nvidia among the backers.
The capital will fund physical infrastructure such as data centres rather than software, reflecting AI's reliance on compute capacity.
Global startup investment hit a record $510 billion in the first half of 2026, already exceeding the $440 billion invested across all of 2025, with nearly 40 AI startups reaching unicorn status.
Nvidia committed $5 billion to Safe Superintelligence in late July and is reportedly in talks to guarantee roughly $250 billion in lease and construction financing for OpenAI's Ohio data centre campus, plus up to $350 billion more for chip purchases.
More than $1.3 trillion was erased from the market value of major semiconductor companies in late July — Nvidia itself losing roughly $238 billion — as investors questioned whether AI infrastructure spending will produce justifying returns.
- Who
- Firmus, an Australian AI infrastructure startup, with Nvidia among its investors; other cited players include Safe Superintelligence, OpenAI, Amazon, Alphabet, Meta and Microsoft.
- What
- Firmus raised $2 billion in equity at a valuation above $10.5 billion to build data centre capacity and physical AI infrastructure.
- Where
- Australia, where Firmus is based; the financing discussions also involve a data centre campus in Ohio in the United States.
- When
- The article is set in 2026; the round comes as global startup investment hit a record $510 billion in the first half of 2026 and after late-July turbulence erased $1.3 trillion from semiconductor market values. No exact date for the raise is given.
- Why
- Because compute is the binding constraint for AI and compute requires physical assets such as data centres, power, cooling and chips, capital is increasingly flowing to whoever will build that infrastructure.

Will AI infrastructure spending pay off?
Skeptics of AI infrastructure spending
More than $1.3 trillion was erased from the market value of the world's largest semiconductor companies in late July — with Nvidia losing about $238 billion — as investors questioned whether AI infrastructure spending will produce returns that justify it.
Supporters of the AI buildout
AI's binding constraint is compute, and compute is a physical asset, so capital flowing to firms like Firmus that build data centres, power, cooling and chips reflects a rational response to that constraint.
Nvidia's role in financing its own customers
Skeptics of AI infrastructure spending
A meaningful share of Nvidia's demand is now underwritten by Nvidia itself, concentrating risk: both sides depend on the same AI boom, so a downturn would arrive as more than one problem.
Supporters of the AI buildout
Nvidia's involvement is not improper — vendor financing is long established in capital-intensive industries, and Nvidia has both the balance sheet and the strategic interest to fund buyers while compute is the bottleneck.
