Anthropic's IPO filing reveals $8bn loss last year

Anthropic has filed its long-awaited S-1, disclosing that the maker of Claude lost $8 billion in 2025 on $4.6 billion in revenue — and used the document to warn investors of "existential risks to humanity" from its own technology. The filing is one of the most candid risk disclosures in recent IPO history, blending boilerplate investor caution with genuine doomsday language from a company that controls what it's warning about.
