The AI You Rent Sits on Very Large Bets. Anthropic's Filing Shows How Large.

Anthropic, the company behind the Claude AI models, is preparing to sell shares on the stock market. Its draft filing, seen by the Wall Street Journal and reported this week, gives the first detailed look inside one of the companies whose AI many office workers now use every day.

The numbers, as reported. Revenue of about $16.3bn in the first half of 2026, against about $1.1bn a year earlier. A net loss of $80.7bn, of which about $72bn is an accounting charge linked to the rising value of its own financing, not cash spent. Spending on computing power of nearly $9bn in six months. And about $450bn promised to Google, Amazon, Microsoft and others for cloud computing over the next seven to ten years, most of it payable whether the capacity is used or not. With a chip lease and deals still being negotiated, reports put the total much higher.

Two details matter more than the big numbers. First, the company says its cloud partners were not willing to provide all the capacity it wanted, so it is leasing data centres, some from operators with a short track record. Second, a large share of revenue comes from a few big customers who are not on long contracts.

Our caveats. This is a draft. The figures come through press reports, not a final public filing, and different outlets give different totals for the cloud commitments. Revenue in the first half was higher than the computing bill, so this does not show that AI is sold below cost.

Why a ship manager should care. For ten weeks we have asked who pays for the AI accounts already used in shipping offices. This filing shows what sits behind those accounts: very large fixed costs, a shortage of computing power, and a business still changing fast. Prices, usage limits and plans can all move. Last week we reported that Accenture capped its own AI spending at $29 per person per month after some staff used much more.

What to do. Know which AI services your staff use and what you pay for each. In any AI contract, look for three things: how the price can change, what happens when the supplier is short of capacity, and how you take your data out. And avoid building a key process on one supplier only.
