Anthropic prospectus lays out losses and infrastructure costs
According to documents reviewed by Reuters, Anthropic lost about $42 billion in 2025, including roughly $34 billion in an accounting charge. Computing costs and future commitments are also drawing scrutiny ahead of its planned IPO.
Summary
Anthropic’s IPO prospectus shows the financial scale of developing and delivering its AI models. Reuters, which reviewed the document, reports that the company generated nearly $4.6 billion in revenue in 2025 but recorded an operating loss of more than $8 billion.
Its net loss approached $42 billion. That figure needs context: roughly $34 billion was an accounting charge linked to a rise in the estimated value of financing instruments that could convert into shares. It does not, by itself, represent cash spent on running the business.
In practice
Anthropic spent $7.33 billion on computing and infrastructure in 2025, about three times as much as the year before, according to Reuters. That accounted for more than half of its $12.65 billion in total operating expenses.
The document also sets out $518 billion in future cloud, computing, and infrastructure commitments over the coming years. These are future obligations, rather than spending incurred in a single year.
The company said two customers accounted for almost a quarter of its 2025 revenue. Many of its largest customers are not tied to long-term contracts and could reduce or stop their spending.
What we still don't know
Reuters reports that Anthropic’s IPO could value the company at more than $2 trillion. That is not a final price: it will depend on the terms of the offering and investor demand. The listing date has not been set either.
The prospectus cited by Reuters was not reviewed directly for this article, so its figures and risk disclosures are attributed to the agency’s reporting. It remains unclear when the infrastructure commitments will fall due and whether revenue growth can keep pace with those costs.
Why it matters
- Rapid revenue growth has not yet made Anthropic’s operations profitable.
- The $42 billion net loss and the operating loss of more than $8 billion measure different things; conflating them misrepresents the company’s finances.
- An IPO would give public investors a closer look at whether demand for AI can support infrastructure commitments on this scale.
