IPO process

The road to an Anthropic listing

No registration statement for Anthropic PBC exists on SEC EDGAR today. This is the standard sequence a US listing follows, so you can judge for yourself how far along — or not — any given rumour actually is.

  1. Private growth rounds

    2021 - present

    Completed

    Successive primary rounds and strategic compute partnerships. Secondary tenders have given some employees liquidity without a listing.

  2. IPO preparation signals

    Watch continuously

    Current stage

    Typical precursors: hiring a CFO with public-company experience, audited GAAP financials, appointment of independent directors, and underwriter selection.

  3. Confidential S-1 submission

    T-4 to T-6 months

    Not yet reached

    Emerging growth companies may submit a draft registration statement confidentially. Nothing appears on EDGAR at this stage.

  4. Public S-1 filing

    T-3 to T-4 months

    Not yet reached

    The registration statement becomes public on SEC EDGAR: risk factors, revenue, customer concentration, share classes and use of proceeds.

  5. Price range & roadshow

    T-2 to T-4 weeks

    Not yet reached

    An S-1/A adds the indicative price range and share count. Institutional roadshow runs; ranges are frequently revised upward or downward.

  6. Pricing & first trade

    T-0

    Not yet reached

    Final IPO price is set the evening before. Trading opens the next morning; the opening print is usually well above the IPO price in hot deals.

  7. Lock-up expiry

    T+90 to T+180 days

    Not yet reached

    Insider shares become sellable. Historically a common source of post-IPO supply pressure.

On the expected subscription price

Any “expected IPO price” circulating before an S-1/A is fabricated. The per-share price depends on the number of shares the company decides to have outstanding at listing, which is disclosed for the first time in the registration statement. A $350B company can price at $20 or $200 per share depending purely on the share count. Judge valuations on total market capitalisation and revenue multiple, never on the headline share price.
