Firmus IPO Demand Cools, Sounding Alarm for AI Data Center Financing Boom
TREE NEWS reports: Australian data center operator Firmus Grid failed to attract enough demand at its target price of A$11 per share, a sharp reversal from just days earlier when the company said its order book was heavily oversubscribed and its valuation was approaching US$30 billion. The company had planned to raise about US$5.5 billion in what would have been one of Australia’s largest-ever listings, but it has yet to announce final pricing or deal structure after closing the book. Market participants now expect a price cut or even a shelved transaction.
The stumble quickly spread to related parties. Maas Group, which holds a stake in Firmus, plunged as much as 30% in Sydney trading on Thursday — its largest single-day drop on record — before closing down 22%. Maas acknowledged “significant speculation and commentary” about whether the IPO can proceed.
Valuation Outpaced the Business
The central problem is that Firmus’s valuation has risen far faster than its operations. The company was valued at about US$10.5 billion in an August funding round backed by investors including Jane Street and Blackstone. Two months later, its IPO target valuation had climbed to nearly US$30 billion.
Yet the actual business remains small. Firmus generated only US$51 million in revenue for fiscal 2026, operates two data centers with just 46 megawatts of built capacity, and while its pipeline reaches 912 megawatts, most of that has yet to be built. The company plans to use IPO proceeds to expand AI data centers across Asia, with customers including Meta and OpenAI and hardware supplied by shareholder Nvidia. That means the valuation depends heavily on future projects and continued access to capital.
Investors are also worried about the lack of a large-scale operating track record, the rich valuation, and potential selling pressure from roughly 58% of shares becoming freely tradable after listing. Regulatory and financing conditions for the data center industry are tightening at the same time.
Institutions Push Back on Price
Institutional investors have begun to voice explicit doubts. Australian pension fund UniSuper decided not to participate. Chief investment officer John Pearce said Firmus “does have a compelling story” but the “valuation is not compelling,” arguing that too many conditions must be met simultaneously to justify it and that expansion will still depend on continuous debt and equity financing.
Ten Cap Investment co-founder Jun Bei Liu said the IPO faces “a lot of investor skepticism,” with the core issue being that Firmus “has not built many data centers yet.” Rayliant Global Advisors portfolio manager Phil Wool called the setback a “historic failure” given the deal had been expected to rank among Australia’s largest.
AI Financing Boom Meets Higher Hurdles
Firmus is not alone. Data center company Accelevation Holdings priced its U.S. listing below its earlier marketed range last month, a sign that investors are demanding more from AI infrastructure assets. Some of the hottest AI-linked trades are also cooling. South Korea’s Kospi index has fallen 27% from its June peak, with the memory-chip rally led by Samsung Electronics and SK Hynix coming under pressure.
Warnings of an AI valuation bubble are growing louder. Ray Dalio this week called AI a “classic bubble,” saying massive debt financing and high interest rates are raising the risk of a burst. Michael Burry, known for “The Big Short,” compared the current equity environment to 2000 and 2008.
The bigger question is how much future revenue AI must generate to absorb today’s investment. Bain estimates the AI industry would need to produce US$6 trillion in annual revenue by 2031 to justify current data center capital spending. Meanwhile, some AI cloud companies are turning to expensive debt. JPMorgan, a joint bookrunner on the Firmus IPO, is also marketing a US$5 billion leveraged loan at roughly 11% for Volta Infrastructure Holdings’ Norway data center project.
Capital Needs Remain Huge, IPO Risk Rises
Demand for AI infrastructure capital has not disappeared. KKR estimates completing global AI infrastructure could require about US$8 trillion, and Anthropic may launch a large IPO as soon as next month. But market attitudes are shifting: investors are no longer awarding high valuations on the AI growth story alone and are demanding proof that revenue growth, project delivery and financing capacity can match the capital being deployed.
Wool warned that as the AI theme peaks, investors are recalculating how much future growth is needed to make years of aggressive fundraising financially coherent. “This will not be the last disappointing AI-related IPO,” he said.
Firmus was founded in 2019 by Oliver Curtis, Tim Rosenfield and Jonathan Levee and began in Bitcoin mining. Joint bookrunners on the IPO included JPMorgan, Bank of America, Morgan Stanley and Morgans Financial.
Key Takeaways for Investors
- Valuation discipline is returning: AI infrastructure names may face sharper scrutiny, especially those with limited operating history and heavy capital needs.
- Watch the read-through: The Firmus setback and Maas Group’s slump could pressure other AI data center listings, private funding rounds and related equities.
- Debt markets matter: High-cost leveraged loans for data center projects show financing conditions are tightening even as capital demand grows.
- Bubble risk is real: With prominent investors warning of an AI bubble, investors should stress-test assumptions on revenue growth, project timelines and dilution.
- Opportunity in volatility: If valuations reset, long-term investors may find better entry points in AI infrastructure, but only for companies that can demonstrate execution and funding access.
