Data Center Valuation Shock: NVIDIA-Backed Firmus Cancels $5B Mega-IPO

The market frenzy surrounding artificial intelligence infrastructure has slammed into institutional capital resistance. On October 9, 2026, Australian high-density data center operator Firmus Technologies—backed strategically by NVIDIA—formally pulled its proposed $5 billion initial public offering that sought an implied valuation of $30–31 billion.

Citing public market volatility, the company stated it will pivot toward private credit markets to fund operations. This retreat marks the first significant macroeconomic indicator of structural valuation fatigue across physical AI infrastructure. Institutional allocators are rejecting speculative multiples for compute hosts amid soaring utility power costs and uncertain payback timelines for rented GPU capacity. The collapse of an IPO of this magnitude demonstrates that public equity demands unencumbered cash flows rather than theoretical compute shortages, driving the industry toward costlier private leverage.
