Firmus IPO Tests the AI Hype Machine With a Record Listing

The Firmus IPO is shaping up as the most divisive stock market debut of the year in Australia — and a live referendum on whether the AI infrastructure boom is still investable. This week the data centre operator priced its listing at eleven Australian dollars a share, implying an equity value of more than thirty billion dollars, according to a term sheet seen by Reuters. That is nearly triple the ten-and-a-half-billion-dollar valuation the company reached in a private fundraising round in early August 2026, and it would make the float the country’s second-largest ever, behind only the 1997 Telstra listing, according to Reuters reporting on Dealogic data.

Demand, at least on paper, looks strong: indicative orders from potential investors have already topped the size of the deal, the term sheet said. But the institutional bookbuild — the window when big investors place orders — was pushed back two days to early October 2026 after a newly signed agreement with Meta forced the company to revise the earnings guidance in its draft prospectus, according to a market roundup from FNArena. The retail offer and the exchange debut, pencilled in for mid and late October 2026, remain on the calendar.

Why the Firmus IPO price has investors split

Skeptics are not hard to find. Merlon Capital Partners portfolio manager Kirit Hara told Reuters his process keeps him anchored to “what’s actually on the table” rather than, in his words, “kind of, the hopes and dreams.” His sticking point is the gap between the price and the physical business: five of the company’s seven planned sites are still to be built, and the prospectus will be the first set of accounts it has ever published. Morningstar strategist Lochlan Halloway described the listing as showing hallmarks of a “boom phase,” pointing to what he called a “wild increase in valuation in such a short period of time.”

The balance sheet adds to the unease. The company is carrying a roughly thirty-billion-dollar debt load, Hara noted, a heavy weight given rising construction and power costs. The draft prospectus shows the company expects to post a first-half loss, with no forecasts beyond that window, while the Australian research outfit Marcus Today put fair value roughly a third below the roadshow’s reported ambitions — and called the float “hyped” even as it conceded the customer roster is, in its phrase, “Australia’s SpaceX” territory. That bull-bear tension is the whole trade: blue-chip tenants and backers on one side, a price that assumes near-perfect execution on the other.

What the company actually does

At the heart of the Firmus IPO pitch, the company builds and runs what it calls AI factories — warehouse-scale data centres packed with Nvidia graphics processors that train and run modern AI models. Two sites are already operating, in Melbourne and Singapore, while five more projects are under development across the Asia-Pacific region. Contracted capacity across the portfolio tops nine hundred megawatts.

The tenant list is the strongest card in the deck. The company counts Nvidia, Meta and OpenAI among its customers, and Blackstone, Nvidia, Coatue and Jane Street among its backers. Late last month it signed fresh agreements to supply Meta with contracted and expandable AI research capacity at its Southeast Asian facilities, built on Nvidia’s full-stack platform, according to Reuters. OpenAI is reported to anchor two Malaysian sites, while a hyperscaler — reported to be Meta — has contracted large graphics-processor deployments across Melbourne and Tasmania, according to the research outfit’s analysis.

The sprint to the listing: a timeline

• Late September 2026: Reuters reports a draft prospectus forecasting a pro forma after-tax loss of seventy-seven million dollars for the first half of the current financial year. The document describes the company as historically loss-making, with IPO proceeds earmarked for capital spending.
• Late September 2026: Firmus signs the Meta AI capacity agreements in Southeast Asia, expanding a relationship that already includes Meta systems at its Melbourne facility.
• Early October 2026: the offer price is set and the institutional bookbuild is pushed back two days after the Meta deal forces a revision to the earnings guidance.
• Mid to late October 2026: retail bidding opens, the prospectus is lodged, and the shares are due to begin trading on the Australian exchange — with a free float of only about fourteen percent of shares and a raising tipped at roughly five billion US dollars.

Why it matters for the AI trade

This is not just an Australian story. The listing lands as global markets argue over whether AI infrastructure spending is a bubble, and Firmus is asking investors to fund a buildout whose most ambitious projection — annual earnings of five billion dollars within five years — depends on facilities that do not exist yet. Independent analysts note the target implies a margin of twenty-eight to forty-three percent, a stretch against the roughly five percent that comparable operator CoreWeave recently reported. If the market swallows the valuation, it validates the AI-infrastructure trade and makes funding cheaper for every data centre developer in the region; if investors demand a haircut, expansion gets harder and the boom’s skeptics get their exhibit A. For anyone whose pension or superannuation fund touches global equities, the verdict on this float will ripple well beyond Sydney.
