Anthropic's Cloud Commitments Reach Seven Times Its Annual Revenue

An updated draft of Anthropic's IPO prospectus surfaced in the press on October 20. According to the WSJ, the company generated $16.3B in revenue in the first half of 2026, up from $1.1B a year earlier.

Its net loss for the period was $80.7B. About $72B of that is a non-cash accounting charge from the rising value of earlier convertible financing, a mechanism we explained in our late-September piece.

The real news in the draft is not the loss but the bill for the coming years. The company carries about $450B in compute commitments, most of which cannot be terminated early. That is roughly seven times its third-quarter annualized revenue of $67.2B.

Who the Commitments Are Owed To

According to reports, $111B of the commitments go to Google Cloud, $110B to Amazon's AWS and $31B to Microsoft. The reports do not break down the remaining roughly $200B.

Setting those figures against the providers' own backlogs shows the scale. A backlog is the total of signed contracts that have not yet turned into revenue.

The companies do not break out their backlogs by customer. The ratios therefore show scale rather than exact share, but for Google and Amazon a single customer equals about a fifth of the backlog.

How a Fixed Bill Works

For Anthropic, this figure reads like a debt. For the cloud providers, it is revenue not yet earned.

Usage-independent payments change a company's cost structure. Compute spending does not rise and fall with revenue; it is paid on the contract's schedule.

The actual payment schedule is not in the reports, and payments need not be spread evenly across years. The direction holds anyway: the bigger the fixed cost, the harder each percentage point of revenue miss hits profit.

Today's spending pace shows the gap. The company spent about $9B on compute and infrastructure in the first half, an $18B annual pace and less than half the average commitment.

The Part That Does Not Fit the Story

The draft does not paint a one-sided risk picture. About 20% of revenue came from two customers, down from nearly a quarter in 2025, so concentration is easing.

Excluding the non-cash item, the first-half loss drops to about $8.7B. The company has also told investors it is profitable on an adjusted basis.

On the other hand, third-quarter growth of 45% quarter over quarter was below the first-half pace. That growth rate is exactly the variable that will decide the commitment math.

The chart shows the broad path of big tech stocks over the past month as IPO news intensified; it cannot be tied to this story alone.

What It Means for Investors

• The market has priced Anthropic's growth, but does not yet appear to have separately priced how concentrated its commitments are in Google's and Amazon's backlogs.
• For Alphabet and Amazon these contracts mean visible revenue; in return, they carry dependence on a single customer.
• Microsoft reports on October 28 and Amazon on October 29; the question is how much backlog growth comes from AI labs.
• The risk that breaks the thesis: if Anthropic's growth slips below 45% a quarter, the fixed bill strains both the company and its suppliers' books.

Sources: Anthropic's first-half figures rely on a draft prospectus seen by the WSJ that has not yet been made public; Reuters said it could not independently verify them, and Anthropic declined to comment. The provider breakdown and two-customer share come from secondary reports; third-quarter revenue is based on the FT. Backlog figures come from the companies' second-quarter disclosures and a Bank of America compilation. Because no payment schedule was disclosed, the even split in the calculation box is an assumption.
