Firmus IPO Pulled: Nvidia-Backed A$44B Float Collapses

The Firmus IPO is dead. The Nvidia-backed AI data center builder withdrew its ASX float on October 9, 2026, after weak demand for a deal that targeted roughly A$44 billion (about US$30.6 billion) and up to US$5.5 billion in fresh shares. Investors balked at a valuation that nearly tripled in two months and at roughly US$30 billion of planned debt.

Key takeaways

• Firmus sought about US$30.6 billion, nearly triple its US$10.5 billion August valuation.
• Expected debt of about US$30 billion is roughly 6x forecast 2028 operating earnings.
• Bloomberg says Firmus may now raise up to $3 billion privately from existing backers.

What happened to the Firmus IPO?

Firmus withdrew its application to list on the Australian Securities Exchange on Friday, October 9, a day after it abruptly closed its books. The company blamed market volatility. Investors blamed the price, the debt load and the thin disclosure. It would have been Australia’s largest float since Telstra in 1997.

According to ABC News, Firmus offered shares at A$11. A day earlier, reports said the company and its advisers were weighing a smaller deal at A$8.25 a share. In the end it chose neither.

In a letter to shareholders, co-founders Oliver Curtis and Tim Rosenfield said they would “continue to assess opportunities that provide the best platform to fund growth,” Reuters reported. Firmus will turn to private markets instead.

How big was the deal?

Big by any standard. Per Dealogic data cited by Reuters, it would have been Australia’s second-largest new share sale and the fourth-largest IPO globally this year, behind SpaceX, CXMT and Cerebras. Bank of America, JPMorgan, Morgan Stanley and Morgans ran the book.

Why did investors reject the Firmus valuation?

Because the price assumed everything goes right. Firmus asked public investors to pay nearly three times what private backers paid in August, for a company with two operating sites, about US$30 billion of planned borrowing and a key partnership that had just fallen apart.

The August round valued Firmus at about US$10.5 billion post-money on a US$2 billion raise, Reuters reported on October 6. Eight weeks later, the IPO price implied US$30.6 billion. Nothing in the public record explains a tripling that fast.

“It’s a compelling story without a compelling valuation,” UniSuper chief investment officer John Pearce told ABC News. He called the stock “priced to perfection” and said he worried Firmus would need repeated debt and equity raises.

What went wrong in the final week?

Several things hit at once. The list below is drawn from Reuters and ABC News reporting:

• The CDC partnership ended. CDC Data Centres CEO Greg Boorer said on a podcast that a plan to develop 1.6 GW of AI factories with Firmus was no longer underway. Investors pulled orders on Wednesday, according to Reuters.
• Insiders could sell early. Escrow terms would have let existing investors sell more than half their stock from day one, Reuters reported.
• Half the deal was going to insiders. About half the IPO was set aside for existing strategic and financial investors, according to Reuters sources.
• Governance questions. ABC News reported that many investors focused on co-CEO Oliver Curtis, a former investment banker who served a year in prison for insider trading about a decade ago.
• A softer tape. US-listed chipmakers fell 3.4% on Thursday after reports that OpenAI’s September annualized revenue was about $50 billion, below earlier signals, Reuters said.

“The market has spoken,” Wilson Asset Management’s Oscar Oberg told Reuters. Blackwattle’s Joseph Koh said the price was too high for an outcome “assuming near flawless execution.”

How much debt does Firmus need?

A lot. Firmus expects about US$30 billion of debt once its data centers are built, roughly six times the US$5 billion of operating earnings it forecasts for 2028, according to Morningstar analysis cited by ABC News. That leverage is the neocloud model in plain sight.

Morningstar’s Lochlan Holloway described how neoclouds work: borrow against customer contracts, buy chips, repay the loans from rent. He said borrowing alone does not make a bubble, but noted that credit is common to most boom-and-bust cycles.

That model is everywhere right now. We covered the same pattern in the $40 billion Apollo-led SpaceX Nvidia chip financing and in Amazon’s $8 billion Nvidia chip leaseback SPV. Firmus is the first big test of whether public equity buyers will fund it at private-market prices.

What does Firmus actually own?

Firmus says it has seven AI factories across Australia, Singapore, Indonesia and Malaysia. Only two are operational, in Melbourne and Singapore, and Reuters reports both are leased. The other five are under development and target ready-for-service within 24 months.

Here is the skeptical read. A US$60 billion enterprise value on two leased sites is a bet on five buildings that do not exist yet, financed largely with debt, after the partner meant to help build them walked away. Public investors declined to underwrite that.

Who loses from the failed Firmus IPO?

Existing shareholders lose a liquid exit and a public mark at US$30.6 billion. Suppliers tied to the build-out lose visibility. And the broader neocloud pipeline loses a valuation comparable just as other AI infrastructure names line up to list.

The most direct listed casualty is contractor Maas Group, which owns 3.2% of Firmus and holds about A$1.2 billion of fit-out contracts. Its shares fell 22.4% on Thursday before the withdrawal, and it requested a trading halt on Friday, according to market reports summarized by Vantage Markets.

For Nvidia, which holds 7.2%, the stake is small relative to its balance sheet. The bigger risk is signaling. Nvidia has seeded many of the neoclouds that buy its chips, including Lambda, which just raised $4 billion pre-IPO. If those customers cannot reach public markets at rich prices, their funding has to come from somewhere else.

Why this matters

The Firmus IPO was a live test of how far public markets will stretch to fund AI infrastructure. The answer this week: not to triple the last private mark, not with six-times leverage, and not without a clear build partner. That repricing matters for every neocloud planning a listing.

It lands as the biggest names keep raising. Reuters noted that Anthropic is reportedly seeking up to $100 billion in an IPO, and Bloomberg framed Firmus’s collapse as a warning sign for AI funding. Ten Cap co-founder Jun Bei Liu called it an “important reality check,” not the “beginning of the end” of the AI trade.

The physical constraints are real too. Power and permits already limit where AI factories get built, as the Texas data center permit freeze showed. Firmus pitched itself on proprietary energy and cooling technology. Investors wanted proof it can build at scale first.

What to watch next

No new listing date exists, so the signals matter more than the calendar. Watch the size and price of any private round, Maas Group’s response, and whether a US listing resurfaces. Each will show where the real Firmus valuation sits.

• The private round. Bloomberg reported Firmus is exploring up to $3 billion from existing investors. A price below the A$11 IPO level would confirm the markdown.
• Maas Group’s announcement. The contractor’s trading halt was set to run until the morning of Tuesday, October 13, pending an announcement, per Vantage Markets.
• A Nasdaq plan. A person involved told Reuters a Nasdaq listing would follow the private raise. Firmus declined to comment.
• Peer listings. Reported AI infrastructure and lab IPO plans, including Anthropic’s, will show whether Firmus was a one-off or a trend.

Firmus IPO FAQ

Why did Firmus pull its IPO?

Firmus cited recent market volatility and said the offer would not reflect its long-term prospects. Investors had balked at the A$11 price, about US$30 billion of expected debt and the loss of a 1.6 GW partnership with CDC Data Centres.

How much was the Firmus IPO supposed to raise?

Up to US$5.5 billion (A$7.9 billion) including the over-allotment option, according to Reuters. About half was earmarked for existing strategic and financial investors.

What valuation was Firmus seeking?

About US$30.6 billion, or roughly A$44 billion, at a fixed A$11 a share. That was nearly triple the US$10.5 billion post-money value set in its August round.

How big is Nvidia’s stake in Firmus?

Nvidia holds 7.2% of Firmus, according to ABC News. Coatue, Blackstone and Jane Street are also backers.

What will Firmus do now?

Firmus says it will pursue private funding. Bloomberg reported it is exploring raising up to $3 billion from existing investors, and a person involved told Reuters a Nasdaq listing could follow. Firmus declined to comment on either.

Does the Firmus IPO failure mean the AI bubble is bursting?

Not on its own. Ten Cap co-founder Jun Bei Liu called it an important reality check, not the beginning of the end of the AI trade. It does show public investors pricing debt and execution risk more harshly than private rounds do.

The bottom line

Firmus will probably still get funded, just privately and at a lower effective price than A$11. The lesson for the AI trade is narrower than “bubble bursts”: public investors will pay for AI infrastructure, but not at any valuation and not on borrowed money with no track record. Expect the next neocloud float to arrive cheaper, smaller and with tighter escrow terms.
