Firmus shelves multibillion-dollar Australian IPO as investor demand falls short

What Firmus was trying to pull off

Firmus priced its shares at A$11 each, a level that implied an equity value of approximately A$43.7 billion, or around US$30 billion. Shares were expected to begin trading on the Australian Securities Exchange around October 23, 2026. That debut will no longer happen on schedule.

What Firmus actually builds

Firmus develops modular AI data centers, which it calls “AI factories.” The company leans on advanced energy and cooling technologies. Its flagship effort is Project Southgate in Australia. Firmus also has operations in Indonesia. Much of that work centers on its collaboration with NVIDIA. The partnership involves the use of up to 170,000 GPUs. Firmus also has partnerships with OpenAI and Meta tied to cloud services and capacity expansion.

Why the timing went wrong

Firmus cited market volatility as a key factor behind the decision. A deal of this size also leaves little room for error. Raising up to A$5.5 billion in a single offering requires broad participation, not just enthusiasm from a handful of anchor investors.

What this means for Firmus and the AI infrastructure trade

For Firmus, the immediate plan is to tap private-market funding and other alternatives while it keeps building out its projects. The company has already raised more than $2.5 billion across its two 2026 rounds. The things to watch now are concrete. Investors will be tracking the size and pricing of Firmus’s next private round, progress on Project Southgate and its Indonesian operations, and how quickly its GPU deployment with NVIDIA scales.
