Anthropic Lost $42 Billion. Only About $8 Billion Came From Running the Business.

Wed 30 Sep 2026 | Evening

The Numbers

Reuters reports, citing Anthropic's IPO prospectus, a net loss of nearly US$42 billion in 2025. Roughly US$34 billion of that was a valuation-related accounting charge. The operating loss still widened to US$8.06 billion from US$2.98 billion in 2024. Anthropic had US$20.28 billion in cash and short-term investments against US$518 billion of future cloud, computing and infrastructure obligations, and nearly a quarter of 2025 revenue came from two customers. Today's video asks which of those figures is firmest: the loss, the obligations, or the customers.

My Personal Take

My first reaction to US$42 billion was that it had to mean the business was failing. What I almost missed is that US$34 billion of it is an accounting charge tied to valuation, which leaves an operating loss of US$8.06 billion. This morning I wrote about giving CDL credit for cash that has not arrived. The same discipline applies here, in reverse: the US$518 billion is the contracted side of this story, and the customer spending behind it is the side I cannot see. I do not know the period those obligations run over, so I cannot say how large they are in any one year. A disclosed schedule by year would change how I read this. 🦖
