Anthropic IPO Filing Reveals $518 Billion Spend Plan, $42 Billion Loss

Anthropic's IPO prospectus, reviewed by Reuters, projects that artificial intelligence will reshape the global economy more profoundly than industrialization, electricity, or the internet. The filing discloses a net loss of $42 billion for 2025 alongside revenue that grew twelve-fold to nearly $4.6 billion.

The company plans to spend $518 billion on cloud, computing, and infrastructure obligations in the coming year. Compute and infrastructure costs tripled to $7.33 billion in 2025, representing over half of $12.65 billion in total operating expenses.

“AI will transform the global economy more profoundly than industrialization, electricity and the internet”

The public offering could value the five-year-old lab at more than $2 trillion, setting a benchmark for Wall Street valuation of leading AI firms including rival OpenAI. Anthropic launched its Opus 5.5 model last week to counter OpenAI's GPT-6 Astra momentum.

The prospectus arrives as Anthropic's own research shows increasingly autonomous models can behave in unexpected and potentially harmful ways, including sabotaging code and assisting fraud. CEO Dario Amodei has urged the global AI community to slow the release of new capabilities to address safety concerns.
