Anthropic’s S-1 Takeaways: From Giant Compute Commitments to Complex Lock-Ups
Valida Pau, Stephanie Palazzolo, Aaron Holmes, Catherine Perloff, Dakin Campbell and Julia Hornstein dissect Anthropic's public S-1 (Nasdaq: ANT; road show in about two weeks, IPO targeted for the week of 16 Nov). Revenue was $16.3B in H1 2026, including $11.6B in Q2 (2.5x all of 2025), and Q2 brought a $974M operating profit after a $1.7B Q1 operating loss; H1 operating cash flow was +$3.9B. Compute spend rose 3.8x to $8.9B, falling from 251% of revenue in Q1 2025 to 48% by end-Q2. Compute commitments total about $657B over 7-10 years ($417B uncancellable), potentially up to $806B including chip deals under negotiation. Cash was $112B at 30 June. Governance: a public benefit corporation with five share classes; the seven co-founders' Class F share gives them 50.1% voting power on key matters, and the Long-Term Benefit Trust's Class T can be sunset by board/trustee or founder/employee/public-holder votes. Lock-ups are staggered and complicated. Caveats: the filing gives no pricing data, many figures are blank and there are no full Q3 financials; the $80.7B H1 net loss is mostly accounting charges on convertible notes (about $8.4B excluding them); the $1.5T+ valuation is an expectation, not in the filing.
Why it matters
The richest single source yet for Dealroom's Anthropic profile (revenue, profitability, cash, compute contracts, cap-table limits, founder ownership and pay) and for the many suppliers and investors it names. The compute commitment table (Google, AWS, Microsoft, SpaceX, Nscale, Lambda, AMD, Broadcom) is durable intelligence on who is financing and supplying frontier AI, and the lock-up and share-class design will be a template for later AI IPOs.
Executive takeaways
- Scale and profitability: $16.3B H1 revenue ($11.6B in Q2); Q2 operating profit $974M versus a $1.7B Q1 loss; H1 operating cash flow +$3.9B (versus -$2.6B for all of 2025); stock-based comp $2.2B in H1, more than 7x a year earlier.
- Channel dependence: Google and Amazon cloud resale was about $7.8B, or 48% of H1 revenue; distribution fees to cloud resellers were about 17% of H1 revenue; top five customers about 25% of revenue for the nine months to September (one customer was 11% in H1).
- Compute book: Google cloud $114.5B, AWS $110B, Microsoft $44.9B (up from the $31B previously disclosed), SpaceX $120.5B by 2029 (mostly cancellable on 90 days' notice, about $3.1B a month once delivered), Nscale $44.6B, Lambda $41.3B, AMD $20B, plus $161B of non-cancellable Google chips leased via Broadcom; a further $125-150B of Google chips is under negotiation. The mix is shifting from fixed cloud contracts to direct chip leasing in dedicated data centres.
- Balance sheet: $112B cash, $108.6B of convertible notes payable (they convert at IPO unless ownership caps are breached), $6.2B of notes held by Amazon, a revolver of up to $15B and room for more debt.
- Control: Amazon is capped at 12% and Google at 14.99% ownership; the seven co-founders each own about 2% but control 50.1% on key matters through Class F while at least three keep a minimum stake; the Long-Term Benefit Trust can elect a board majority through Class T, which can be eliminated without trustee consent if founders, employees and public holders vote for it.
- Insiders and banks: some insiders can sell up to 10% in the first trading days and another 35% after FY2026 results; co-founders up to 29% after the earlier of 180 days or Q1 2027 results. Spark Capital has put in nearly $800M over six rounds, and GP Yasmin Razavi is the only VC on the board. Goldman Sachs is lead left, Morgan Stanley stabilisation agent, with 20+ banks and international tranches on the SpaceX playbook.
What The Information may be missing
No IPO size or price range yet (Reuters had reported up to $100B raised), so the valuation remains speculation. There's little on Q3 beyond the customer-concentration figure, even though other reporting (OpenAI discounting at Rippling and Replit) suggests margin pressure. It doesn't quantify how much of the cloud-resale revenue is effectively Google and Amazon credits recycled from their own investments, or how dependent the $657B of commitments is on suppliers such as Nscale and Lambda raising their own debt. The ownership stakes of venture holders other than Spark (Menlo, Lightspeed, ICONIQ and others) are not broken out.
