Anthropic IPO progression data points:

• (06-01) Anthropic confidentially filed a draft S-1 with the SEC.
• (06-03) Picked Morgan Stanley + Goldman Sachs to lead the IPO; valued $965B last round, surpassing OpenAI's valuation for the first time.
• (06-01) Expected to close >$1.8T market cap day-one; SpaceX + Anthropic combined IPO-day mcap >$3.5T.

Feeds open task #161 (Anthropic/OpenAI public-S-1 watch → run the AI-Lab S-1 crosswalk playbook when the public S-1/A with financials drops; the confidential draft isn't readable yet).

Takeaway

From a 30-day @KobeissiLetter pull. Status: social-source claims — verify against EDGAR / Bloomberg before artifact use. Routes to the Anthropic child-track holding-pen thread — NOT the spacex-ipo-liquidity-event perspective (per the SpaceX↔Anthropic track-separation rule; no perspective tag on this event by design).
