Anthropic's updated IPO filing: $17B quarter, $895B in compute deals, and what's still blank
Quick answer
On Nov 2, Anthropic filed Amendment No. 1 to its IPO prospectus with the SEC, adding results through Sept. 30 (SEC filing). The Claude maker reported $33.24 billion in revenue for the first nine months of 2026, about $17 billion of it in the third quarter, and about $895.4 billion in purchase and lease commitments, “substantially all” for compute and infrastructure (CNBC).

The key numbers
- Q3 revenue: about $17B, up about 1,127% year over year (CNBC).
- Nine-month revenue: $33.24B, up roughly 1,200%.
- Growth is slowing quarter to quarter: Q3 grew about 47% over Q2, after 144% in Q2 and 132% in Q1.
- Net loss: $104B for nine months, mostly from changes in the fair value of convertible notes and derivatives, not day-to-day operations. Q3 net loss was $23.29B.
- Compute bill: about $895.4B in committed spend. Compute and infrastructure expenses rose $14.4B (329%) over the same nine months last year.
What’s still blank
- IPO price, share count, proceeds and listing date. The filing proposes Nasdaq under the ticker ANT (SEC filing).
- The roadshow hasn’t started.
Why it matters
- For Claude users: a company this size that’s growing this fast is likely to keep shipping, but the compute bill is the thing to watch. Price or limit changes usually follow compute crunches.
- For the AI race: Anthropic gets much of its compute from Amazon, Google and SpaceX, per CNBC. OpenAI filed confidentially in June and is signaling a 2027 debut.
- Risk factors: the filing has 90+ pages of them, including political headwinds and balancing safety with commercial goals.
FAQ
- Can I buy Anthropic stock yet? No. The IPO hasn’t priced and there’s no listing date.
- Is a $104B loss a red flag? Most of it is an accounting change in the value of convertible notes and derivatives, per the filing as reported by CNBC. The operating picture is in the revenue and compute lines.
- What’s the ticker? ANT, proposed for Nasdaq.
