Firmus scraps $44bn ASX float as investor demand evaporates for AI datacentre venture

Firmus Technologies pulled the plug on what would have been Australia's largest stock market debut in nearly three decades, abandoning a $44 billion valuation after it became clear that investor appetite for the AI datacentre venture had simply dried up. The company, backed by chip maker Nvidia and major Wall Street firms including Blackstone, Jane Street, and Coatue, had been preparing to raise $7 billion through an initial public offering scheduled for October 23 on the Australian Securities Exchange. By midweek, the picture had shifted entirely. Bankers working on the deal had dramatically overestimated how much demand existed among institutional investors, prompting urgent conversations about slashing the proposed $11-per-share price. Rather than proceed with a diminished offering, Firmus's board decided the float no longer served the company's interests or those of its shareholders. A company spokesperson announced on Friday morning that Firmus would now turn to private markets and explore alternative funding paths, promising shareholders more details as those options developed.

The collapse marks a stunning reversal for a company that had been positioned as a transformational player in Australia's AI infrastructure landscape. Firmus operated only two small datacentre sites but had convinced some of the world's most sophisticated investors that it could build a sprawling network of liquid-cooled AI facilities across Australia and Asia. That confidence evaporated as the float approached. Skepticism had been mounting for weeks over whether a startup in its early phase could justify a $44 billion valuation, particularly given its limited operational footprint and the gap between its ambitious forecasts and its actual track record. The company's founders—Oliver Curtis, his cousin Tim Rosenfield, and Curtis's former brother-in-law Jonathan Levee—stood to see their anticipated wealth substantially reduced.

The timing of the withdrawal sent shockwaves through related parts of the market. Maas Group, an early investor in Firmus, saw its share price plummet more than 20 percent on Thursday as traders absorbed the implications. There had been growing concern, reported earlier by Guardian Australia, that existing Firmus investors were counting on the public float as their exit strategy, potentially leaving retail investors holding the bag if enthusiasm for the company cooled. That scenario never materialized because the enthusiasm never reached the public markets in the first place.

The unraveling accelerated after a separate partnership collapsed. CDC, a veteran datacentre operator, had announced what was billed as a $73 billion joint venture with Firmus called Project Southgate, aimed at building sovereign, renewable-powered AI infrastructure with Nvidia as an anchor customer. That deal, first announced in October of the previous year, fell apart this week as the two companies' visions diverged. Speaking before Parliament's joint standing committee on AI on Friday, CDC's chief strategy officer Dr. Jack Dan explained that Firmus's business model had shifted significantly since the partnership began. When Firmus was more focused on building sovereign Australian AI capability, the alignment made sense. But as Firmus evolved into a more commercially oriented venture, the fit deteriorated.

Dan described CDC's approach as centered on critical infrastructure with extreme resilience and near-total availability—requirements that demanded rigor, assurance, and process. Firmus, by contrast, was pursuing a leaner, more commercially flexible model for developing datacentres. Those competing philosophies proved incompatible. Dan noted that CDC had existed for nearly two decades in relative obscurity, but datacentres had suddenly become central to Australia's national conversation about AI capability and sovereignty. That heightened scrutiny may have also contributed to the partnership's unraveling, as both companies faced pressure to justify their strategies and commitments.

With the ASX float abandoned, Firmus must now chase capital from private investors to fund its expansion plans. The company has not disclosed how much money it needs immediately or what timeline it faces. Its backers remain substantial—Nvidia and the Wall Street firms that supported the float have not publicly walked away—but the path forward is now far more constrained and uncertain than it appeared just weeks ago. The company that was supposed to anchor Australia's position in the global AI infrastructure race will instead operate in the shadows of private markets, building its network without the scrutiny or validation that a public listing would have provided.
