Anthropic IPO Prospectus Reveals $8 Billion Operating Loss

Anthropic posted a roughly $42 billion net loss in 2025 as soaring computing costs and a massive accounting charge overwhelmed rapid revenue growth ahead of the artificial intelligence company’s planned initial public offering.

The Claude maker generated about $4.6 billion in revenue during 2025, up roughly twelvefold from the prior year, while its operating loss widened to $8.06 billion, according to its confidential IPO prospectus reviewed by Reuters. Most of the gap between Anthropic’s operating and net losses came from a roughly $34 billion non-cash accounting charge tied largely to financing instruments that may eventually convert into company shares.

The results offered one of the clearest looks yet at the enormous costs behind the artificial intelligence boom as Anthropic prepares to ask public investors to value the company at more than $2 trillion.

Anthropic spent $7.33 billion on compute and infrastructure in 2025, nearly 60% of its $12.65 billion in operating expenses and about 1.6 times the company’s total annual revenue, according to Capital Brief. Compute and infrastructure expenses climbed about 190% from the previous year.

The company also disclosed roughly $518 billion in future cloud, computing and infrastructure obligations, underscoring how much capital Anthropic expects to require as it expands its models and computing capacity, according to Reuters.
