ASX hopeful Firmus has withdrawn its planned initial public offering (IPO), blaming “market volatility” for a lack of investor interest in its proposed $US5 billion raise, saying it will now look at “other options” for its $US51 billion build of five AI data centres.
This week’s bookbuild has not gone to plan, despite claims by the float’s underwriters and brokers that investor interest was supposedly “well in excess of the offer size” of $7.1 billion.
The Tasmanian-headquartered startup was just two weeks away from listing on the ASX at a $43.7 billion market capitalisation.
But the company now has a different view.
“Having considered recent market volatility and prevailing market conditions, the board determined that the terms on which the offer could proceed would not appropriately reflect the strength of the company’s business and long-term growth outlook,” Firmus said in a statement on Friday morning.
“The board therefore concluded that proceeding with the offer was not in the best interests of the company and its shareholders.”
Firmus said it “will now pursue capital from the private markets and consider alternative public and private market options”.
The company had been planning to spend around $4.4 billion of its IPO proceeds on servers and deployment in Tasmania and Southeast Asia, as it races to build AI data centres sites in Malaysia, Indonesia, and locally over the next two years.
The immediate challenge for the business is finding that capital to keep those projects on time.
The overall plan outlined in the IPO is expected to cost $51 billion.
The company claimed it had $20 billion in combined contract revenue once they all came online by 2028.
Chip maker Nvidia – a key investor in frontier labs and data centres, including Firmus – will play a key role in any future success.
The rise and fall of Firmus
The rise and fall of Firmus has been an astonishing arc in what many viewed as a market bubble, as capital piled into the sector amid growing unease about the rise of AI and data centres by some politicians and communities.
Firmus was founded in 2019 by Oliver Curtis, Tim Rosenfield, and Jonathan Levee, and originally focused on Bitcoin mining before pivoting to AI data centres in 2024.
OpenAI and Meta are signed on as clients, and Firmus rents its Nvidia chips to them.

A year ago, Firmus was worth just $1.85 billion.
Two months ago, it was worth $15 billion following a $2.85 billion raise backed by Nvidia, Blackstone, and Jane Street.
Morgan Stanley, one of the IPO’s four joint lead managers – alongside Bank of America, JPMorgan, and Morgans Financial – had suggested Firmus could be worth between $US65 billion ($93 billion) and $US90 billion ($130 billion).
Investors took a different view.
After initial hype, with the IPO share price set at $11 last week to raise $7.1 billion, the float began to wobble on Tuesday when CDC founder Greg Boorer revealed that his company’s partnership with Firmus to build AI data centres around Australia had been abandoned because the two sides were “misaligned”.
Firmus CEO Oliver Curtis told Startup Daily that it was “mutually agreed earlier this year” that the two companies would not to proceed with the partnership – less than a year after announcing the $73 billion Project Southgate collaboration, which was meant to deliver 1.6 gigawatts of compute.
How it unraveled
By Wednesday night, things began to unravel as the IPO team considered cutting the share price from $11 to $9 following a poor response from investors.
That potentially wiped $8 billion from the company’s market capitalisation.
Ongoing speculation suggested a $8.25 share price and the valuation being cut by around 25 per cent.
The Australian reported advisers were subsequently testing appetite at $5.50, half the original price, as they tried to keep the deal alive.
Firmus withdrew from appearing before a federal parliamentary inquiry into AI on Thursday morning, amid the chaos of trying to salvage the float – having already postponed an attempt to list on the ASX earlier this year due to a lukewarm response from investors.

Bloomberg echoed the concerns of many about the float, from Firmus’s limited operating track record – it currently has just 46 megawatts of compute, with another 865MW in the pipeline – to its future financing needs and the potential for selling pressure, with 58 per cent of shares available to trade on listing.
Short-sellers were already waiting to pounce.
And now the clock is ticking for many of the players involved, including local Firmus investors such as Regal Partners, Wilson Asset Management, Paradice Investment Management, Ellerston Capital, Frazis Capital Partners, and Rapital Capital.
The AFR reported that a listing delayed beyond 30 November would trigger arrangements giving Nvidia, Blackstone, Coatue and other investors a larger equity share, and diluting earlier holders, including the founders, who’d become paper billionaires from the rising valuations.
The question they now have to answer is how much capital and risk those original true believers are prepared to take on, and at what valuation, for a neophyte neocloud AI infrastructure company surrounded by better capitalised competitors, with a long road ahead.
