The abrupt withdrawal of Australian data centre developer Firmus’s initial public offering has left a significant question mark over the massive paper returns accumulated by early investors. Firmus, a neocloud data centre developer, saw its valuation skyrocket from $2 billion in September 2025 to $44 billion just prior to its high-profile IPO. Touted as Australia’s “SpaceX” moment, the float was pulled after offshore investors, including San Francisco-based Coatue Management, developed cold feet, causing those lofty valuations to be called into question.
The Firmus IPO fizzle has sent shockwaves across the broader artificial intelligence sector, according to Airlie Funds Management’s portfolio manager Ray David. Shares in neocloud market leader CoreWeave plummeted almost 16 per cent in five sessions, with its April-issued bonds trading at about 15 per cent, a level signalling distress. Concurrently, the Philadelphia Semiconductor Index wiped out more than $US1.6 trillion in market value with a 12 per cent slide. Higher government bond yields also scuppered plans for Blackstone-controlled AirTrunk to list assets on the Singapore Exchange, while ASX-listed NextDC slumped and Nasdaq-listed Iren dropped nearly 13 per cent.
The collapse presents a valuation dilemma for funds that backed Firmus early. Fund Monitors chief executive Chris Gosselin noted investors must decide whether to scale back their valuations to cost price or adhere to the August private funding round, which valued Firmus at $US10.5 billion. Tectonic Investment Management and Ellerston Capital, significant early backers, have both opted to value their stakes in line with the August raising. Regal Partners, which saw its initial $10 million investment surge to $300 million, has already cashed out $170 million, with a remaining $130 million stake, valuing it at the latest observable capital raise. Gosselin stressed the critical role of trustees and administrators in October’s month-end pricing, warning of redemption risks for inflated valuations and performance impacts for undervaluation.
