> People familiar with the matter tell Bloomberg — republished by The Economic Times — that Anthropic could begin formal IPO marketing as soon as the week of Nov. 9, putting a debut in line to trade before Thanksgiving (Nov. 26), with year-end still the outer bound. Some of those people put a fair valuation in a $1.8–2 trillion range. Timeline can still move. Not a filing; Anthropic has not confirmed the timetable in the inspected text.

The calendar just got sharper — and it is still **sourced talk**, not an S-1 you can download.

**Bloomberg**, bylined **Bailey Lipschultz** and republished by **The Economic Times** on **October 3, 2026**, reports that **people familiar with the matter** say **Anthropic PBC** is seeking to go public as soon as mid-November and **could start formal IPO marketing as soon as the week of Nov. 9**, putting it in line to begin trading **before Thanksgiving (Nov. 26)**. The same people say a debut is still expected **no later than year-end**, deliberations are ongoing, and **the timeline could continue to shift**. They asked not to be identified because the information is not public. This desk read the **Economic Times reprint only**; it did not open a Bloomberg original URL.

## What the sources put on the clock — and what they do not

Some of the people familiar put a **fair valuation in the $1.8 trillion to $2 trillion** ballpark — investor talk, not a priced deal. The ET piece also says Anthropic expects to **match or beat SpaceX’s IPO size**, attributed to earlier Bloomberg reporting, and that **OpenAI has postponed its IPO plans**, with **Sam Altman** arguing it would be ill-advised to list now. **Dario Amodei**’s personal-site essay arguing that model-advance speed must slow is mentioned as color beside renewed OpenAI competition and rogue-agent scrutiny — not as an IPO timetable confirmation.

Financial figures in the same ET article (roughly **$42 billion** 2025 net loss, roughly **$4.6 billion** 2025 revenue, operating loss above **$8 billion**) are attributed to **earlier Bloomberg reporting and documents**, not to a new filing this weekend. Those economics already traveled in [Reuters’ prospectus account](https://timesof.ai/2026/09/anthropic-ipo-prospectus); they are not a fresh S-1 drop.

## The capital-markets trade

If the Nov. 9 marketing week holds, the largest pure-play model lab moves onto a public-market roadshow clock while safety scrutiny is still live — and opposite OpenAI’s reported choice to stay private for now. That is a **timing and ownership** story. It is **not** a confidential-filing confirmation, not a priced book, and not a company press release. Prior desk threads on [October investor meetings](https://timesof.ai/2026/07/anthropic-ipo-investor-meetings-october), [Nasdaq timing chatter](https://timesof.ai/2026/09/anthropic-nasdaq-ipo-q2-profit), and the [prospectus leak](https://timesof.ai/2026/09/anthropic-ipo-prospectus) remain background; this increment is the mid-November marketing window from a single Bloomberg origin.

## Limits

- **Single originating report:** Bloomberg, read only via the Economic Times reprint. No independent non-Bloomberg corroboration inspected; Bloomberg canonical URL not opened.
- Marketing week, pre-Thanksgiving trade, year-end outer bound, and $1.8–2T band are attributed to **people familiar** — timeline can still move; Anthropic confirmation not in the inspected text.
- This is not a filed S-1 or a priced IPO. SpaceX-size comparison and 2025 P&L figures are earlier Bloomberg / document reporting, not this weekend’s news.
