Anthropic's IPO Clock: Investor Day Oct 14, Public S-1 Due ~Oct 23, Trading Target Before Thanksgiving

The Anthropic IPO — the largest pending liquidity event for the SF AI-wealth housing channel — now has a dated timeline, though the public S-1 still hasn't landed. Bloomberg (Oct 1, via FinanceFeeds) reports Anthropic "invited a select group of institutional investors" to its San Francisco headquarters on October 14, with "formal IPO marketing potentially starting the week of November 9 and trading beginning before Thanksgiving on November 26" (FinanceFeeds). Critically: "As of October 11, a publicly accessible Anthropic S-1 could not be located in the available EDGAR records, 132 days after the original confidential submission" (June 1). SEC's 15-day rule makes Friday, October 23 the practical public-filing deadline if the Nov 9 roadshow holds — that's the next hard checkpoint for the watch.

The leaked prospectus numbers (Reuters/Fortune, via FinanceFeeds): $4.6B 2025 revenue, $8.06B operating loss, and a **$42B net loss — of which ~$34B was convertible-financing accounting, not cash** — plus $7.33B of 2025 compute/infrastructure spend. NYT reports the raise could exceed $100B; banker/valuation discussions run $1.8T–$3T against a $965B May Series H post-money. Morgan Stanley, Goldman Sachs, JPMorgan and Citigroup lead. Broadcom has reportedly agreed to loan Anthropic up to $42B (Globe and Mail), and New Constructs called it "the most ridiculous IPO of 2026" (CNBC, Oct 7) — a reminder the wealth event carries its own market-risk tail.

For the SF housing thesis: the payday that Redfin estimated could let OpenAI+Anthropic employees buy ~⅓ of every SF home with proceeds now has a window (late Oct filing → Nov 26 trading target)¹ — landing after the midterms and right as SF sits alone as a top-tier seller's market with 9.6% price cuts (SF Is Now the Only Top-Tier Seller's Market: 9.6% Price Cuts vs 21.1% Nationally as AI Wealth Meets 7% Mortgages). Prediction markets put before-2027 odds at ~72.5% (CryptoSlate tracker).
