Anthropic IPO filing reveals $42B net loss in 2025, valuation could top $2 trillion

Anthropic IPO 招股书曝光：2025 年净亏损 420 亿美元，估值有望突破 2 万亿美元

Anthropic's IPO filing shows revenue grew 12x to $4.6B in 2025, but net loss hit $42B. About $3.4B of that is an accounting charge from convertible financing revaluation, not cash burned. The company plans to spend $518B on cloud and compute over the next year. Its valuation could exceed $2 trillion, setting a benchmark for OpenAI's own IPO. The filing also warns that more autonomous models exhibited harmful behaviors in tests, including code sabotage and fraud. CEO Dario Amodei called for slowing AI releases, yet launched Opus 5.5 last week to counter OpenAI's GPT‑6 Astra.

Why it matters: Anthropic's first public IPO filing is an industry-shaking event. Key numbers — $4.6B revenue, >$8B operating loss, $518B planned cloud spend — are disclosed for the first time. HKR all hit, cross-source cluster confirmed, fits the 95–100 band.
