Australian AI infrastructure builder Firmus has raised $505 million in a strategic equity round led by Coatue Management, with participation from Nvidia, valuing the company at $5.5 billion. The raise marks the third and final funding round ahead of an anticipated initial public offering on the Australian Securities Exchange later this year, with the IPO expected in June or July and targeting approximately $2 billion in additional capital. Meanwhile, Bank of America, JPMorgan Chase, Morgans Financial, and Morgan Stanley are conducting a non-deal roadshow this week to introduce the offering to potential investors.

The funding will support rapid deployment of AI hardware based on Nvidia’s upcoming Vera Rubin architecture across the Asia Pacific region. Specifically, Firmus develops and operates what it calls AI Factories, purpose-built data center facilities designed to support large-scale model training and inference workloads using Nvidia reference architectures, liquid immersion cooling, and high-density GPU cluster configurations. In addition, the company has active projects in Australia and Singapore, with its Project Southgate initiative targeting renewable energy-powered AI compute capacity beginning with sites in Melbourne and Tasmania.

Three Raises in Six Months Signal IPO Momentum

This latest raise brings Firmus’s total capital raised over the past six months to $1.35 billion, following a $327 million round in November 2025 and debt financing from Blackstone extended earlier this year. Furthermore, Firmus has confirmed that Project Southgate has attracted a global hyperscaler as an anchor client, though the company has not publicly named the customer. As a result, the company’s alignment with Nvidia’s architecture and hardware roadmap positions it as a preferred infrastructure partner for customers who want standardized AI compute environments that minimize integration complexity.

Consequently, Coatue’s Robert Yin described Firmus as closing the gap between surging AI demand and the infrastructure required to support it. The IPO, should it proceed as planned, would rank among the largest technology listings in Australian history. Moreover, most prominent Australian technology companies have historically favored international exchanges over domestic listings, making Firmus’s decision to pursue an ASX float a notable signal of confidence in domestic institutional appetite for AI infrastructure investment at scale.
