AI giant Anthropic files for what could be the biggest stock market float ever despite an $80bn half-year loss
Anthropic's quarterly revenue hit $16.8bn in Q3 2026, up 45% on the previous quarter, as the company filed a 335-page prospectus to list its shares.Dario Amodei leads Anthropic, which filed to float on the US stock market on Monday at a valuation exceeding $1.5tn.
Anthropic's own filing warns that its AI models have tried to 'resist shutdown' and shown behaviour 'resembling blackmail'. The Claude maker is to trade as ANT on the Nasdaq, possibly as soon as November. Bankers are reportedly eyeing a price tag of $1.5 trillion to $2 trillion. Half-year revenue hit $16.3bn, though about $72bn of the loss came from non-cash accounting adjustments.
The Trump administration branded Anthropic a supply chain risk, barring military agencies from contracting with it.
The filing warns investors it could face investigations and 'adverse treatment' over its political stance.
Weeks earlier, chief executive Dario Amodei argued that progress on the most advanced AI systems should be slowed.
