The cancellation of a major Australian initial public offering (IPO) has triggered a wave of concern among investors over the valuations and financing strategies of AI-related companies globally. Firmus, a data centre operator supported by Nvidia and Blackstone, withdrew its planned listing a week ago, which was set to be Australia’s second-largest IPO with an implied valuation of approximately A$44 billion (around $30.5 billion). Shortly thereafter, AirTrunk, another Australian data centre firm, also called off the Singapore listing of its real estate investment trust vehicle, citing unfavorable market conditions.
These developments come amid a broader sell-off in chip and AI-related stocks driven by inflationary pressures and unease about the sizable debt levels companies are accumulating to fund ambitious expansion plans. Mike Intrator, CEO of the US-based neocloud company CoreWeave, referred to the Australian IPO setbacks as reflecting wider market challenges affecting his own business, which has seen a sharp decline in share price. Intrator noted that rivals like Firmus and AirTrunk were attempting to raise "enormous amounts of capital" without the operational scale or revenue that his company possesses. This environment has led investors to offload debts issued by some neocloud firms, with bonds trading at distressed levels and yields approaching 15 percent.
Firmus, co-founded by Oliver Curtis and Tim Rosenfield, began as a bitcoin mining company in Tasmania in 2019 before pivoting to AI infrastructure. The company attracted backing from prominent investors but faced skepticism over its rapid valuation increase—it sought a valuation double that of its fundraising round just three months earlier. The target valuation also dwarfed those of established data centre firms such as NextDC, Goodman Group, and CDC Data Centres. Some Australian superannuation funds, including UniSuper, opted out of participating in the IPO due to concerns about the high valuation. Additionally, disclosure a week prior to the planned listing that a multibillion-dollar project with CDC, known as Project Southgate, had collapsed further unsettled prospective investors.
Oliver Curtis’s past insider trading conviction and perceived flamboyant lifestyle were also cited by some as factors deterring investment, with critics suggesting a degree of “tall poppy syndrome” influencing market sentiment. Investor James Packer remarked that Australia tends to be less supportive of aggressive entrepreneurs compared to the United States, which he described as more nurturing of such figures.
Firmus reported nearly $1 billion in net debt as of June but moved into a net cash position in August after a $2 billion capital injection from Blackstone and Coatue. However, the company was expected to raise up to A$30 billion in debt following the IPO to finance data centre construction across Australia and Asia. This level of debt would equate to about six times its projected 2028 earnings, raising concerns about sustainability amid tightening credit markets. The company has indicated it will seek alternative private and public financing options to support its growth plans.
The aborted IPO has raised questions about Australia’s ambitions to become a hub for AI and digital infrastructure investment, particularly as the government promotes the country’s stable political environment, participation in the Five Eyes intelligence alliance, and renewable energy transition as competitive advantages. Andrew Charlton, Australia’s assistant minister for science, technology, and digital economy, has previously highlighted these factors in attracting AI investment from global firms such as Anthropic and OpenAI.
Market participants at an investment conference in Noosa expressed a cautious mood. Jun Bei Liu, founder of investment firm Ten Cap, criticized Firmus and its advisers for overreaching on valuation and advised more realism in future fundraising efforts. Meanwhile, economists note that Australia’s data centre sector is expanding rapidly, presenting opportunities for long-term growth, though they acknowledge the environment may be less favorable for speculative or overly aggressive capital raises.
Though the recent IPO setbacks have rattled markets, some analysts remain optimistic about Australia’s potential to carve out a significant role in the global AI ecosystem over time. The pullback may serve as a reset, encouraging investors and companies to pursue more sustainable growth amid an evolving and challenging market landscape.
