On 11 2, Anthropic filed the first amendment (S-1/A) to its S-1 prospectus with the U.S. Securities and Exchange Commission (SEC), adding third-quarter figures that were missing from last week's initial version. The prospectus states: Revenue for the three months ended 9 30 was 170 billion USD, a year-over-year increase of 1,127%; operating loss was 5.67 billion USD, compared to an operating profit of 9.74 billion USD in the previous quarter, primarily due to 50 billion USD in short-term compute commitments (with unit prices significantly higher than multi-year contracts) and 20 billion USD in non-cash expenses related to the employee donation matching program. Adjusted operating profit, excluding stock-based compensation and donations, was 25 billion USD. Net loss for the quarter was 232.91 billion USD, largely driven by non-operating items such as fair value changes in convertible notes, derivative liabilities, and SAFEs. As of 9 30, committed expenditures for compute and data center leases totaled approximately 8954 billion USD.
Confidence: High (100) · Event Date 2026-11-02
Rationale
- This is the first time a leading model company has disclosed quarterly figures according to public company standards: revenue growth far outpaced the growth of compute and infrastructure costs (the prospectus states the latter grew by 382% in the same period), but once demand exceeded expectations and high-priced temporary compute was procured, profits immediately turned negative, indicating that the profitability of frontier model companies is highly dependent on the pace of compute procurement.
- Long-term commitments of nearly 9000 billion USD indicate a heavy bet on demand for the coming years; the prospectus states that revenue for the first 9 months was 332 billion USD and operating loss was 13 billion USD, a significant narrowing compared to the 52 billion USD operating loss in the same period last year.
- According to reports from Bloomberg, Reuters, The New York Times, and others, as relayed by The Decoder and SiliconANGLE, this IPO may raise approximately 1000 billion USD with a target valuation of 1.5 trillion to 2 trillion USD; these figures are not in the prospectus.
Usage
- The original document is on the SEC EDGAR system: search for Anthropic, PBC (CIK 0002130357), file number 333-299633 for the S-1/A; the Management's Discussion and Analysis section contains quarterly revenue, expenses, and non-GAAP reconciliation tables.
Risks
- SiliconANGLE reported the Q3 operating loss as 5.36 billion USD, which is inconsistent with the 5.67 billion USD figure in the prospectus text; this entry relies on the prospectus as the authoritative source; the statement that "revenue grew 12 times" is a media interpretation based on year-over-year growth rates.
- The fundraising size, valuation, and subscription amounts by Japanese investors are all sourced from media reports citing unnamed sources; the prospectus has not yet specified the offering price or number of shares; the prospectus itself also has a marketing nature, and statements regarding growth and efficiency are self-reported by the company.
