Anthropic IPO Prospectus Reveals $42 Billion Net Loss and $518 Billion Infrastructure Plan

Anthropic's IPO prospectus reveals a massive financial scale, reporting a $42 billion net loss for 2025 and plans to spend $518 billion on cloud, computing, and infrastructure obligations in the coming years. The company's revenue grew 12-fold in 2025 to nearly $4.6 billion, but it lost more than $8 billion on an operating basis. The $42 billion net loss includes a roughly $34 billion accounting charge related to previous fundraising, rather than operational spending. Anthropic spent $7.33 billion on compute and infrastructure last year, a threefold increase from 2024. The public sale could value Anthropic at more than $2 trillion, more than double its previous estimated valuation. The company holds $20.28 billion in cash and short-term investments. Anthropic CEO Dario Amodei has stated the company is betting AI will transform the global economy more profoundly than industrialization. The prospectus also highlights risks, noting that nearly a quarter of revenue comes from two customers who could reduce spending. Anthropic recently released its Opus 5.5 model to compete with OpenAI's GPT-6 Astra. OpenAI, which confidentially filed for an IPO in June, is expected to list in 2027. Anthropic's debut is likely to be pushed to after the November US midterm elections.
