AirTrunk, the Blackstone-backed data centre operator, is delaying its planned initial public offering in Singapore, according to a Wall Street Journal headline on 13 October 2026. Bloomberg reported the same day that the company is said to be delaying a $1.5 billion IPO. Both articles are paywalled, and we read only their headlines.
The reports came four days after Firmus, the Nvidia-backed builder of AI data centres, withdrew its application to list on the ASX, ABC News reported on 9 October 2026. Firmus cited recent market volatility and conditions.
According to ABC News, Firmus said the offer would not appropriately reflect its long-term growth prospects, and that it would pursue private market funding while considering other options. “We will provide additional information to shareholders as those options progress,” the company said in a statement.
ABC reported that the float was set to be the biggest on the Australian share market since Telstra in 1997. The company’s co-chief executives, Oliver Curtis and Tim Rosenfield, targeted a A$44 billion valuation, ABC said, at a sale price of A$11 a share, and the day before the withdrawal reports emerged that the price could be lowered to A$8.25.
Nvidia has a 7.2 per cent stake in Firmus, ABC reported. Firmus’s website lists seven AI factories across Australia, Singapore, Indonesia and Malaysia, two of them operational and five under development, according to the same report.
Firmus expects to carry about US$30 billion of debt once its data centres are built, about six times the US$5 billion of operating earnings it forecasts for 2028, as ABC News reported on 9 October 2026.
Business Pill · FINANCIAL CONDITIONS
A one-minute explainer of financial conditions: how easy or costly it is to borrow, and why that matters for companies funding large investments with debt. It teaches the general idea only and says nothing about any company in this story.
The key insight: As we read it, both deals test the same thing: whether public investors will fund AI data centres on the terms their builders want. In the Firmus case ABC reported, the objection was the price and the debt, not demand: Pearce called the story compelling and the valuation not.
Why Investors Held Back
UniSuper chief investment officer John Pearce told ABC the capital raise would be about A$7 billion, giving Firmus a total market value of around A$44 billion. “We think that Firmus indeed has a compelling story. It just doesn’t have a compelling valuation,” he said.
Pearce added that UniSuper was “quite concerned that Firmus will have to keep coming back to the market for a lot more debt and more equity to fund its expansion plans.”
Morningstar senior market strategist Lochlan Holloway wrote that “The neo-clouds are heavily geared,” ABC reported, adding: “The model is to borrow against customer contracts to buy chips, then use the rent to repay the loans.”
Once its data centres are built, Firmus expects to carry about US$30 billion of debt, ABC reported, about six times the US$5 billion of operating earnings it forecasts for 2028.
What Is Reported About AirTrunk
The Wall Street Journal’s headline on 13 October 2026 read: “Blackstone-Backed Hyperscale Data-Center Operator Delays Singapore IPO”. MarketScreener’s summary headline the same morning named the company: “AirTrunk to delay Singapore IPO, WSJ reports”.
Bloomberg’s headline was “Data Center Operator AirTrunk Is Said to Delay $1.5 Billion IPO”. The headline says AirTrunk “is said to” delay the IPO and does not name the source.
Two AI data centre listings in one week: Firmus withdrew its ASX listing application on 9 October 2026 (ABC News), and AirTrunk is delaying its Singapore IPO, according to WSJ and Bloomberg headlines on 13 October 2026.
The AI Data Centre IPO Pipeline
The two deals sit in a wider queue of data centre and neocloud listings this publication has covered: DayOne’s US IPO filing, which showed 69% of revenue from one customer, and Nscale’s IPO drafts, the first of which named ByteDance.
As we read the Firmus case, the investor objections ABC reported were about the financing model rather than demand for AI capacity: Pearce called the story compelling but the valuation not, and Holloway described the model as borrowing against customer contracts to buy chips.
The Structural Read
Firmus’s own numbers, as ABC reported them, show the scale of the borrowing: about US$30 billion of debt once its data centres are built, against US$5 billion of operating earnings forecast for 2028.
Holloway’s description of the neocloud model, borrowing against customer contracts to buy chips and repaying from the rent, is why an IPO matters to these companies: equity sits underneath that debt.
As we read it, a withdrawn float and a delayed one in the same week move the next financing decision to private markets, which is where Firmus said it would now go.

Three Implications
FIRMUS ABC reported that Firmus withdrew its ASX listing application, citing market volatility and conditions, and will pursue private market funding while considering other options.
AIRTRUNK WSJ and Bloomberg headlines on 13 October 2026 say the Blackstone-backed operator is delaying its Singapore IPO; Bloomberg’s headline puts it at $1.5 billion.
NEOCLOUD INVESTORS UniSuper’s Pearce told ABC he was concerned Firmus would have to keep coming back to the market for more debt and more equity to fund its expansion plans.
The framework puts it this way: “The thesis: the capex race is no longer a corporate spending cycle. It is a sovereign-scale financing problem dressed in tech-company clothing — and the financial architecture is starting to invert.”
As we read it, a data centre builder that expects debt of about six times its forecast earnings, and then cannot list at its target price, is that financing problem showing up in the equity market.
What Is Not Established
We did not read the Wall Street Journal or Bloomberg articles on AirTrunk, which are paywalled, so the reason for the delay, the new timing and any details beyond the headlines are not established here. The $1.5 billion figure is Bloomberg’s, as stated in its headline.
AirTrunk and Blackstone are not quoted in anything we read. Firmus’s statement is as ABC News reported it; the size and terms of any private funding Firmus pursues are not established in that report.

AirTrunk is delaying its planned Singapore IPO, according to Wall Street Journal and Bloomberg headlines on 13 October 2026, with Bloomberg putting the deal at $1.5 billion. Four days earlier, Firmus withdrew its ASX listing application, citing market volatility and conditions, after investors questioned a valuation of about A$44 billion and a model built on borrowing against customer contracts, ABC News reported.
A note on sourcing. The AirTrunk report rests on the headlines of the Wall Street Journal and Bloomberg articles of 13 October 2026, and MarketScreener’s summary headline; the articles themselves are paywalled and were not read, so we use only what the headlines say. The Firmus account is from ABC News’s report of 9 October 2026, read in full on 13 October 2026, including Firmus’s statement as ABC reported it. Australian-dollar figures are marked A$.
