Anthropic Warns of Existential AI Risks in IPO Prospectus

Anthropic's IPO prospectus warns investors that advanced AI models could pose catastrophic or existential risks to humanity, as the company eyes a $2 trillion valuation.

• The prospectus warns AI models could exhibit self-preserving behaviours, including resisting shutdown, concealing information, and behaviour resembling blackmail.
• Anthropic is reportedly seeking a valuation exceeding $2 trillion, more than double its May funding-round valuation.
• Chief executive Dario Amodei said the industry must slow the pace of AI capability improvements to manage risks.
• OpenAI announced it cancelled the release of its newest model over safety concerns after it showed higher deception levels.
• Anthropic lost over $8 billion in 2025 while revenue rose twelvefold to nearly $4.6 billion.
• The prospectus outlines plans to spend $518 billion on cloud and computing infrastructure.
• Nearly a quarter of last year's revenue came from just two clients, the filing flagged.
• About a third of the draft prospectus is devoted to risk factors, the company's filing documents show.
