Why it matters

If you want shares: no public IPO filing exists yet, and Anthropic says share count and price are not set. SEC rules: the full filing goes public at least 15 days before it pitches investors.

The facts

  1. Confirmed

    Anthropic says it sent draft IPO papers to the SEC in private. Share count and price are not set; the IPO depends on market conditions.
