Firmus, an Nvidia-backed company that builds AI data centers, pulled its planned listing on the Australian Securities Exchange in early October 2026. The float aimed to raise about $5 billion at a valuation of roughly $30 billion, but demand was weak and the deal was withdrawn after about two days.
Big investors, including pension fund UniSuper, said the company had a good story but too high a price, and worried about how much it would need to borrow.
Firmus earned about $51 million in revenue last financial year.
Only 46 of its planned 912 megawatts of capacity is built.
Its clients include OpenAI and Meta.
Firmus is now talking to existing investors about a private raise of $2 billion to $3 billion and may list in the US later. The flop is being read as a warning sign for the AI building boom.
Two days. That’s roughly how long Firmus’s blockbuster stock market debut lasted once big investors got a look at the price. The Nvidia-backed AI data center company withdrew its planned listing on the Australian Securities Exchange in early October 2026, after weak demand for a share sale that would have valued it at around $30 billion.
Why should you care if you don’t own a single AI stock? Because Firmus is a test case for the whole AI building boom. Companies are pouring hundreds of billions of dollars into data centers, and this was one of the first big public tests of whether ordinary investors, including the pension funds that hold many people’s retirement savings, would pay up for it. Many of them said no.
01
Why the Firmus IPO in Australia was pulled
Firmus said it pulled the Australian IPO because of recent market volatility and current market conditions, and that the terms on offer would not have reflected the strength of its business or its growth outlook. Going ahead, the board decided, would not serve the company or its shareholders.
The investors who walked away told a blunter story. The float aimed to raise about $5 billion at a price of A$11 a share. That would have made it one of the largest share sales in Australian history. Signs of stress showed up soon after the books opened to big institutions, and the deal was withdrawn after about 48 hours of bookbuilding.
UniSuper, one of Australia’s largest pension funds, was among those that stayed out. Its chief investment officer, John Pearce, said Firmus had a compelling story but not a compelling valuation, and that so much would have to go right to justify the price. He also worried the company would need to borrow even more to fund its growth. Other investors were concerned that existing shareholders might sell shares soon after the debut.

What Firmus does, and who backs it
Firmus builds and runs liquid-cooled data centers it calls AI factories, packed with Nvidia chips and rented out for heavy AI work. Its clients include OpenAI and Meta, and its backers include Nvidia, Blackstone and Jane Street.
The company has an unusual origin story. It started in 2019 as a Bitcoin mining business in Australia, founded by Oliver Curtis and Tim Rosenfield. Today it has data centers in Melbourne and Singapore, with five more under development across the Asia-Pacific region.
The numbers show why some investors hesitated:
Revenue: about $51 million in its 2026 financial year.
Capacity: a pipeline of 912 megawatts, of which only 46 megawatts has actually been built.
Recent funding: $505 million in April in a round led by Coatue Management, followed by $2 billion pledged by a group including Nvidia and Blackstone.
Valuation jump: it was reportedly valued at $10.5 billion in a private round just two months before the IPO, so the float would have roughly tripled that.
One analyst, Phillip Wool of Rayliant Investment Research, summed up the worry by calling the deal more like a bet on a dream, since buyers would be backing an early-stage company likely to borrow heavily.

What it means for the AI boom, and your money
For everyday investors, the lesson is that even a company with Nvidia, OpenAI and Meta on its resume can’t name any price it likes. Some fund managers saw the withdrawal as a good result, because it spared small investors from buying shares that might have slumped after listing.
It also fits a wider mood. Investors and analysts have grown uneasy about the vast sums going into AI while long-term returns remain unclear. On the day the news broke, Nvidia and Oracle shares fell in US trading after reports that OpenAI’s revenue was lower than previously thought. OpenAI CEO Sam Altman had already said in September that OpenAI would not aim to list this year.
Australia has its own stake. The country has become a magnet for data center investment thanks to plentiful clean energy, natural gas and land, and it already has more than 160 data centers. Altman has said it could lead the industry if it wanted to. Some Australians have pushed back over the environmental impact and noise. Pearce called the outcome disappointing, saying the exchange needs new stories and this could have been one if correctly priced.

What happens next for Firmus
Firmus says it will now seek money from private markets and consider other public and private options, and will update shareholders as those plans progress. It is talking with current investors about a private round of $2 billion to $3 billion, possibly mixing equity and debt. Existing backers had already planned to put in roughly half of the IPO money, which could speed things up. Over the longer term, the company is also weighing a US listing.
The aftermath kept rolling through October. A later report said Nvidia was moving to back Firmus after IPO investors balked. Morgans Financial, Morgan Stanley, JPMorgan Chase and Bank of America had been lined up to run the sale.
The next thing to watch is the size and terms of any private deal, which will show what professional investors really think Firmus is worth.
Firmus blamed market volatility and conditions. Big investors such as UniSuper said the roughly $30 billion valuation was too high and worried about the company’s debt needs.
How much was the Firmus IPO meant to raise?
About $5 billion, at A$11 a share, which would have made it one of Australia’s largest ever share sales.
Will Firmus try to list again?
Not right away. It is pursuing a private raise of $2 billion to $3 billion and may consider a US listing in the longer term.
