Anthropic revenue: $17B in one quarter and $895B in commitments

On November 2, Anthropic filed an amended S-1 with the SEC that adds its third-quarter results. Anthropic revenue for July–September 2026 came to $16.956 billion, up from $1.382 billion a year earlier, an increase of 1,127%. According to CNBC, the company is about to start its roadshow, the series of investor presentations before its Nasdaq debut.

What’s new?

A week ago I wrote about the first public version of the prospectus, which stopped at the half-year results. The new version adds the third quarter and fills the gap I mentioned back then: the total amount committed to compute.

The key numbers from the new filing:

1. Revenue for the first nine months of 2026: $33.242 billion, up from $2.545 billion a year earlier (+1,206%).
2. Q3 revenue: $16.956 billion (Q2: $11.555 billion).
3. Q3 net loss: $23.3 billion; for the nine months, $104 billion.
4. Purchase commitments and leases: about $895.4 billion.

How fast is Anthropic revenue growing?

Still very fast, but the pace is slowing. The quarterly table in the prospectus shows Q3 revenue about 47% above Q2. Before that, quarter-over-quarter growth was 144% (Q2) and 132% (Q1).

For comparison: as recently as Q4 2024, Anthropic was making $197 million a quarter. The prospectus also says trailing 12-month revenue per employee exceeded $6.6 million, up from $1.4 million a year earlier (headcount is about 5,300).

Interestingly, the prospectus ties part of this growth to cheaper models: according to the filing, Opus 5.5 cut the cost per task for customers by about 40% compared with Opus 5, and the lower cost drives more usage (I wrote about the model itself when covering fast mode in Opus 5.5).

Where does a $23 billion loss in one quarter come from?

As in the first half, mostly from accounting rather than operations. The change in fair value of convertible notes and other financial instruments cost $21.9 billion in Q3. The higher Anthropic is valued, the more expensive the securities that convert into its stock become on the books.

The operating side is more interesting. In Q2 Anthropic had $974 million in operating income; in Q3 it was back to a loss: $567 million. According to the prospectus, two things drove this:

1. $5 billion for compute bought under short-term contracts, which costs much more than compute from multi-year deals,
2. $2 billion in non-cash costs from a program in which the company matches employees’ charitable donations with stock.

Compute and infrastructure spending was $9.863 billion in Q3, almost double the previous quarter ($5.558 billion). Adjusted operating income (a non-GAAP measure calculated by the company) rose from $2.2 billion to $2.5 billion, but the margin fell from 19% to 15%.

What is the $895 billion for?

The prospectus says “substantially all” of it relates to compute and infrastructure. It breaks down like this:

1. about $447.5 billion through the end of 2030,
2. nearly all of the rest in 2031–2045,
3. about $69.8 billion due within 12 months of September 30, 2026.

That’s more than 26 times the revenue for the first nine months of 2026, so it’s no surprise this is the number drawing the most attention ahead of the debut. According to CNBC, investors are currently worried about AI infrastructure spending and rising interest rates.

What to watch

First, the still-blank price. The new version of the prospectus still doesn’t give a price range or the number of shares offered.

Second, the growth rate. 47% quarter over quarter is still a result most companies can only dream of, but it’s a clear slowdown after two quarters of growth above 130%.

Third, compute costs. Q3 shows that buying compute in a hurry can eat up the entire operating profit.

For us Claude users, this is good news on one hand: there’s money for the next models, and the cost per task is falling. On the other hand, a company that has committed to spending almost $900 billion will be under pressure to earn that money back, which may show up in prices and limits.
