What started as a marquee listing for an Nvidia Corp.-backed AI data center operator quickly turned into triage. Late Tuesday in Sydney, fund after fund told the deal team the $30 billion valuation was a stretch. By Wednesday morning, it was obvious the IPO could not proceed as sold, triggering a scramble to slash the size to roughly $3 billion or reset the valuation between $20 billion and $25 billion. The internal code name was Australis, but the rescue effort never landed.
By late Thursday morning local time, bookbuilding closed as scheduled with no clear word on pricing or structure, and anxiety swirled around whether there was enough support at the A$11 marketed level. In Sydney trading, shares of backer Maas Group Holdings Ltd. fell by as much as 30%, the biggest drop on record.
The broader market first got uneasy when it emerged that existing shareholders would not be subject to escrow, raising the risk of a flood of stock. By Wednesday, push notifications lit up with headlines flagging weak demand and the possibility of a price cut. One fund manager even cut short a coffee meeting in Hong Kong to verify what was happening, and that afternoon bled into a long night of confusion.
Updates were scarce. Some investors trimmed their orders; others yanked them entirely as the situation looked shaky. On Bloomberg TV, Ten Cap Investment's Jun Bei Liu, a co-founder and lead portfolio manager, said, "I've never seen an IPO so polarizing," and added that if the listing fails, the company would direct the deal to its current backers.
In the end, U.S. buyers did not show up as hoped, domestic appetite could not fill the gap, and by Friday morning the listing was off. The company began exploring a smaller private raise with existing investors, who were already set to take about half the IPO shares.

Firmus had claimed "strong strategic and global investor demand" when it moved to set the IPO terms, and bankers indicated interest exceeded the offer size. But skepticism had been bubbling for months. UniSuper, one of Australia's biggest pension funds, said back in July it would not participate, citing limited visibility into the business.
The valuation jumped fast. Not long before, Firmus closed a $2 billion round that pegged the company at more than $10.5 billion, bringing in heavyweights like Jane Street Group and Blackstone Inc., after an April round with Coatue Management LLC and Nvidia valued it at $5.5 billion. When it formally tested IPO appetite in late September, the offer size of up to $5.5 billion was already larger than many expected, signaling it wanted investors to pay up for results still to come.
On fundamentals, investors saw a company early in its buildout: a 912 megawatt pipeline with only 46 MW completed. The pitch leaned on an EV to EBIT multiple of 13 times based on forecasts two years out, benchmarked to CoreWeave Inc., which has a longer track record and far larger revenue. Many were comfortable around $25 billion, but just days before pricing, Firmus announced an agreement with existing customer Meta Platforms Inc. for computing capacity at its Southeast Asia factories and then updated its figures, steering the pricing push. Investors were being urged to value the company at more than $30 billion even though revenue in the 2026 financial year was $51 million, a case built on rapid growth that would require additional funding in the billions.
There were softer issues, too. Co-founder Oliver Curtis' prison term for insider trading a decade ago was not seen as a deal-breaker, but it did not help. Nor did a burst of critical local coverage.
Bank of America Corp., JPMorgan Chase & Co., Morgan Stanley and Morgans Financial Ltd. were on the top line for the float. A Morgan Stanley spokesperson declined to comment; the other banks did not respond. A Firmus representative also declined to comment.
Takeaway for your wallet: hype can sprint, but due diligence walks. When public investors balk at price, even buzzy AI stories can hit a wall, and related names can feel it fast. If you held Maas Group, you saw that in real time.
