Firmus Pulled Its $30 Billion Australian IPO Because Investors Would Not Pay the Price

Key points

• Firmus, an AI data centre company backed by Nvidia, Blackstone and Jane Street, cancelled its planned Australian Securities Exchange listing in October 2026 after investors balked at a valuation of more than $30 billion.
• UniSuper, one of Australia's largest pension funds, publicly said the company had a "compelling story" but not a "compelling valuation."
• Firmus operates liquid-cooled data centres, which it calls "AI factories", serving clients including OpenAI and Meta across Australia, Singapore and the broader Asia-Pacific region.
• The collapse adds to a pattern of investor hesitation around AI infrastructure spending at a moment when long-term returns remain unclear.

Firmus isn't a household name, but it does the physical work that makes AI run. The company builds and operates liquid-cooled data centres, large buildings full of specialised computers that generate enormous heat and need constant industrial-scale cooling. Its clients include OpenAI, the company behind ChatGPT, and Meta, the parent of Facebook and Instagram.

Citing "recent market volatility and prevailing market conditions", Firmus pulled its planned listing on the Australian Securities Exchange. IPO stands for initial public offering, the process by which a private company sells shares to the public for the first time. The planned deal had valued Firmus at more than $30 billion, which would have placed it among the largest public offerings in Australian history.

Why did investors walk away?

The price was the problem, and UniSuper's chief investment officer John Pearce said so plainly. "We think that Firmus indeed has a compelling story. It just doesn't have a compelling valuation," Pearce said in an update to investors. He told the BBC, which reported the details, that UniSuper also worried Firmus would need to take on significant additional debt to fund its expansion.

Pearce's broader comment stings for Australia's markets. "It's disappointing. The ASX needs new stories and this could have been one if it was correctly priced," he said.

Blackstone, one of the world's largest investment firms and a Firmus backer, declined to comment. Nvidia and Jane Street, a major trading firm that also backed the company, had not responded to requests for comment at the time of the BBC's report.

What does this mean for the wider AI infrastructure bet?

Investors are getting more careful, not less interested. Firmus is not walking away from growth; it says it will raise money from private investors and weigh other public or private options.

Bond costs matter here too. As we reported on 30 September, rising US Treasury yields are already squeezing smaller players in the AI infrastructure build, and Pearce's specific concern about Firmus taking on more debt sits squarely in that context.

The timing is pointed. AI-related stocks including Nvidia and Oracle fell in US trading recently after reports that OpenAI's revenues were lower than previously thought. OpenAI boss Sam Altman said in September 2026 that the company was not planning a stock market listing this year. Anthropic, OpenAI's main rival, faces similar scrutiny; both companies are eyeing eventual listings that analysts have said could value them above $1 trillion each.

Australia itself remains attractive for data centre investment, with abundant clean energy and natural gas supplies. More than 160 data centres already operate in the country, with more planned, though some local communities have pushed back over noise and environmental concerns.

The honest read is that the AI infrastructure build-out is real and large, but investors are now asking basic questions about price that the industry hasn't always had to answer. Firmus may well go public eventually. It just can't charge whatever it wants to get there.

Common questions

What is an AI data centre and why does it cost so much to build?

An AI data centre is a large facility packed with specialised computers, called GPUs (graphics processing units), that do the heavy number-crunching AI systems need. They require industrial-scale power and cooling, which makes them extremely expensive to build and run.

Does this affect OpenAI or Meta's services?

No. Firmus pulling its IPO is a financial event, not an operational one. Its data centres keep running; only the ownership structure and fundraising path are changing.

Should you worry about AI stocks?

The Firmus situation is a reminder that high valuations carry real risk, particularly in sectors where future profits are still unproven. Anyone holding AI-related stocks should check what assumptions about long-term revenue their investment is actually priced on.
