PRIMARY company statement (Anthropic newsroom). Anthropic confirms it confidentially submitted a draft Form S-1 to the SEC on 2026-06-01.

Key facts (from the company statement):

• "The number of shares to be offered and the price have not yet been set."
• No listing venue, ticker, or timeline disclosed.
• A confidential draft does NOT appear on EDGAR; the public S-1 must post ≥15 days before any roadshow. Verified: Anthropic is not yet an EDGAR registrant with a public filing.
• Secondary reporting (NPR 2026-06-01) frames post-money ~$965B off the $65B Series H; no IPO date set.

Lane use: this is a child-case trigger (Anthropic track owns Claude demand / hyperscaler circular financing / compute book). It belongs to the parent lane ONLY as regime-clustering evidence: SpaceX public S-1/A (2026-06-01), OpenAI confidential draft (~2026-05-22, secondary), and Anthropic confidential draft (2026-06-01, primary) are now stacked inside a ~2-week window. That clustering is direct evidence toward the parent lane's graduation criterion #3 ("the market treats the IPOs as one allocation regime") — but a confidential draft is NOT a public S-1, so the graduation gate has not yet fired. Do not relabel this as parent-owned; cross-link only.
