Firmus $5.5B IPO is an Australian AI data center company listing on the ASX in October 2026. Its $5.5B valuation dates from April, and the IPO prices are far higher. A larger share base after the offering could let Nvidia, already a Firmus investor and chip supplier, buy more shares without a single large block purchase. That is an analyst view rather than a confirmed plan.

What is Firmus and why does Nvidia care?
Firmus builds and operates AI data centers designed around Nvidia hardware. Its facilities are built for Nvidia-based hardware and software so customers can run standardized training and inference environments. Nvidia is an investor, supplier, and commercial partner at once, which makes Firmus a direct extension of Nvidia’s own demand.
How big is the Firmus IPO?
Firmus $5.5B IPO is one of the largest in Australian history. Firmus had been valued at US$5.5B in April and was reported above US$10.5B by August. It has since priced at A$11 per share and aims to raise about A$7.2B, which would make it Australia’s second-largest IPO after Telstra’s in 1997. Reports differ on the final valuation, so check the prospectus once it is lodged.
What does “room to add more shares” mean for Nvidia?
When a company issues new shares, existing holders’ percentage ownership shrinks unless they buy more. Nvidia holds roughly 7.2% of Firmus, alongside Coatue at about 8.4% and Blackstone at about 6.7%. A bigger, more liquid share base lets Nvidia top up its position in smaller, easier increments, either in the offering or on the open market after listing.
This is interpretation, not a disclosed intention. Neither Nvidia nor Firmus has said it will buy more. Watch the prospectus for cornerstone allocations and Nvidia’s disclosed holding after listing.
How deep is the Nvidia and Firmus relationship?
The tie goes beyond Firmus $5.5B IPO. Firmus and Nvidia agreed to deliver 170,000 GPUs to a Batam, Indonesia campus from Q1 2027, and Nvidia receives a share of cloud revenue as well as hardware sales. Nvidia’s returns therefore depend on Firmus succeeding as well as on selling it chips.
Why is the Firmus IPO linked to circular financing?
Circular financing means a supplier invests in a customer that then spends the money on the supplier’s products. Critics argue this can make revenue and demand look larger than they are, and the Firmus IPO is seen as a test of how far investors will accept the model. If public investors price Firmus well, it strengthens the case that demand is real. A weak debut would feed the skeptics.
What are the risks investors are weighing?
- Losses. The draft prospectus reportedly expects a US$77M loss in the current half-year.
- Debt. Some institutional investors question whether Firmus’s growth forecasts justify the valuation given its heavy debt load.
- Concentration. Much of the growth story rests on a few large customers and on Nvidia’s roadmap.
- Lock-ups. Founders can sell only 10% of their shares after 12 months and another 39.9% after two years. This offers some reassurance, but the supply overhang matters later.
What is the Firmus IPO timeline?
The institutional bookbuild opens October 6 and closes October 7, the prospectus is expected October 8, and the retail offer runs October 12 to 19. Trading is expected to begin October 22 or 23, depending on the source. All dates can change until the prospectus is final.
