Anthropic publicly filed a Form S-1 on October 26, 2026 to list Class A common stock on the Nasdaq Global Select Market under “ANT”. Share count and price range are not set. The figures below come from press coverage of the filing (Fortune, BetaNews and others); we have not read the filing text ourselves.
The numbers (first half of 2026)
- Revenue: $16.3B, about 13.5x the roughly $1.2B in the same period of 2025. About 80% was consumption-based fees, much of it not tied to multiyear contracts.
- Net loss: $80.7B, mostly non-cash. About $72.4B came from revaluing convertible notes and similar instruments as the company’s valuation rose.
- Operating loss: $693M, versus $2.14B a year earlier. Adjusted operating income (non-GAAP) was $1.62B.
- Compute and infrastructure costs: $8.95B, up from $2.33B.
- Liquidity at June 30: $112.4B in cash and equivalents plus $19.3B in short-term investments. Operating cash flow was +$3.93B, partly due to payment timing.
- Customers (trailing 12 months to Sept 30): 1,900+ generating at least $1M each, about 250 at least $10M, and 11,900+ at least $100K.
Offering and governance
- The company and selling stockholders are both offering shares; 22 banks are underwriting, led by Goldman Sachs and Morgan Stanley.
- Reports expect a Thanksgiving-week debut, a valuation of $1.5T to $2T, and investor meetings starting the week of Nov. 9. These are expectations, not confirmed terms.
- Anthropic is a public benefit corporation. A Long-Term Benefit Trust elects most directors, and the co-founders hold 50.1% of votes through a single Class F share, making it a controlled company.
Compute commitments
One equipment lease requires about $125.2B in rent over five years, excluding interest. Outside analysis tallies minimum cloud commitments of about $269.4B across Google Cloud ($114.5B), Amazon ($110.0B) and Microsoft Azure ($44.9B). That total is one outlet’s own sum of three figures, reported from secondary coverage; the filing does not state it.
Where to be skeptical
- The $80.7B loss is largely an accounting effect of a rising valuation, so it says little about operating health. The reverse is also true: a headline loss that size is not “just paper” if instruments convert into dilution.
- Revenue growth of ~13x is from a small base, and mostly usage-based, which can fall as quickly as it rose.
- Filing risks include cross-defaults across contracts, requested capacity that providers did not commit to deliver, unclear liability when AI agents act for customers, an FTC civil investigative demand in October, and an ongoing court dispute over a US government supply-chain-risk designation.
- Valuation range and timing come from reports, not the filing.
Takeaway
The S-1 gives the first audited-style view of a frontier AI lab’s economics: very fast revenue growth, cash positive operations, and enormous multi-year infrastructure obligations. Whether those obligations are matched by durable demand is the central question for investors. This is a summary of public reporting, not investment advice.
