Anthropic files updated IPO paperwork showing $17 billion Q3 revenue and massive infrastructure spend

Anthropic released its third‑quarter results in an amended S‑1 filing ahead of a planned IPO. The company posted Q3 revenue of about $17.0 billion, a 1,127% year‑over‑year increase, but recorded a net loss of $23.3 billion and an operating loss of $567 million. Operating expenses rose 292% year over year to $17.5 billion, driven by compute outlays. The filing also disclosed a committed infrastructure spend of roughly $895.4 billion, including $69.8 billion due within the next twelve months.

The filing shows that despite explosive top‑line growth, Anthropic will carry a multi‑billion‑dollar loss and a long‑term capital commitment that could pressure valuation and investor appetite. The company’s IPO is targeting a valuation between $1.4 trillion and $2 trillion, which hinges on how investors assess the sustainability of its loss profile and spending commitments.
