Anthropic's IPO prospectus, reviewed by the Financial Times and Reuters, reveals an operating loss of over $8 billion in 2025 on revenue of nearly $4.6 billion, a twelvefold increase. The document devotes nearly a third of its content to risk factors, including warnings that its AI models could resist shutdown, conceal information, or exhibit behavior resembling blackmail, and even mentions existential risks to humanity. The company plans to spend $518 billion on cloud and computing infrastructure in the coming years. In 2026, Q2 revenue alone reached $11.5 billion, with expectations of a second consecutive quarter of adjusted operating profit. The prospectus also flags customer concentration, with nearly a quarter of 2025 revenue coming from just two clients.
