Nvidia-backed AI startup Firmus abruptly cancels $5 billion IPO as investors question $30.6 billion valuation

Nvidia-backed Australian AI infrastructure startup Firmus has abruptly canceled its planned $5 billion initial public offering, just days after signaling strong investor demand for what would have been one of Australia’s largest-ever stock market debuts. The sudden reversal comes as investors question the company’s proposed $30.6 billion valuation, nearly three times what it was worth just two months ago.

Firmus confirmed the decision on Friday, citing market volatility and unfavorable offering terms. The company had been preparing to list on the Australian Securities Exchange, with shares reportedly priced at A$11 apiece. The offering would have ranked as the second-largest new share sale in Australian history.

In a statement provided to CNBC, Firmus said its board concluded that the proposed IPO terms failed to reflect the strength of its business and long-term growth prospects.

“The board therefore concluded that proceeding with the offer was not in the best interests of the company and its shareholders,” Firmus said.

“Firmus will now pursue capital from the private markets and consider alternative public and private market options,” the company added.

The withdrawal marks a stunning reversal for a startup that appeared to have everything going its way: backing from Nvidia, billions in private funding, agreements with Meta and OpenAI, and growing demand for AI computing infrastructure.

Yet those advantages were not enough to convince public-market investors that Firmus was worth more than $30 billion.

According to Reuters, investors raised concerns about the company’s valuation, financing needs, limited operating history, and risks surrounding its ambitious data center construction plans. The deal’s terms for existing shareholders added to those concerns.

Firmus’ valuation nearly tripled in two months

The speed of Firmus’ valuation increase helps explain why its proposed IPO attracted so much scrutiny.

In August, the Sydney-based company raised $2 billion from investors including Nvidia, Coatue Management, Blackstone, and Jane Street. The financing brought its valuation above $10.5 billion and total new equity raised over the preceding year to more than $3 billion.

By October, Firmus was seeking a public valuation of approximately $30.6 billion.

That represents an increase of roughly $20 billion in just two months, before the company had completed much of the infrastructure supporting its future growth plans.

Firmus currently operates two AI data centers, one in Melbourne and another in Singapore. Five additional facilities are under development across Australia and Southeast Asia.

The company has announced more than 900 megawatts of contracted capacity, but much of that infrastructure remains under construction. For investors, that creates a difficult question: How much should a company be worth today when much of its expected future revenue depends on facilities that have yet to become operational?

The Financial Times reported that investors were concerned about the gap between Firmus’ planned capacity and the infrastructure already generating business.

Those concerns carry particular weight in AI infrastructure, where constructing data centers, securing electricity, buying GPUs, and deploying cooling systems can require billions of dollars before projects produce meaningful returns.

What Firmus’ failed IPO says about the AI infrastructure boom

Firmus is no ordinary data center operator. The company develops modular AI factories built around Nvidia computing systems, combining specialized cooling, energy infrastructure, and cloud services for demanding AI workloads.

Its customer relationships include some of the biggest names in artificial intelligence.

In September, Firmus announced agreements with Meta to provide GPU computing capacity at AI facilities in Southeast Asia. Meta is already using Nvidia Blackwell Ultra systems at the company’s Melbourne location.

Firmus has a separate agreement with OpenAI to provide dedicated AI computing capacity from two planned facilities in Malaysia.

Those contracts give Firmus a credible position in the AI infrastructure market. They do not eliminate the financial and construction risks involved in delivering the promised capacity.

The canceled IPO comes at a time when investors are paying closer attention to the enormous sums being committed to AI data centers and the returns those investments may eventually generate.

For Firmus, the immediate priority shifts back to private financing. Its existing investors and commercial agreements could help it secure fresh capital without accepting the valuation or offering terms public markets demand.

The broader implications extend beyond Australia.

AI infrastructure companies have attracted enormous investments on expectations of sustained demand for computing capacity. Firmus’ failed listing suggests that public investors may be growing less willing to price those expectations as though the promised infrastructure, revenue, and profits have already arrived.

The demand for AI computing has not disappeared. But Firmus’ sudden IPO withdrawal shows that even a startup backed by Nvidia may struggle to convince investors to pay almost three times its valuation from two months earlier.
