TL;DR
Anthropic’s October 26 preliminary registration statement lays out an unusual combination of founder voting control, large supplier commitments and disclosures about AI safety risks. A critical reading by Thorsten Meyer argues that investors should look beyond headline losses and revenue to understand the company’s governance, financing and accounting; some totals in the analysis are the author’s calculations, not figures stated directly in the filing.
Anthropic’s preliminary registration statement, dated October 26, gives prospective investors details that extend beyond its financial headline figures: a founder-held share with 50.1% of voting power, extensive supplier financing and commitments, and explicit disclosures about AI-related risks. In an October 27 analysis, Thorsten Meyer of ThorstenMeyerAI.com argues these provisions deserve close scrutiny as investors assess what an eventual public offering would give them.
Meyer says the filing spans 415 pages, in addition to an eight-page founders’ letter included as images. His analysis focuses on governance, financing relationships, accounting presentation, executive incentives and the company’s discussion of AI risks. The S-1 is preliminary: its disclosure describes the proposed share structure and business risks, but the source material does not establish an offering date or final terms.
Under the structure described in the filing, Class A shareholders receive one vote per share, while their class’s voting power is capped at 49.9%. A single Class F share held through a founders’ LLC carries the other 50.1%, and its voting power is designed not to dilute when more Class A shares are issued. Meyer also says a trust elects four of the seven directors. The filing describes conditions under which the founder share’s control could end, rather than giving it a fixed expiry date.
The analysis draws attention to supplier relationships and accounting. It says Anthropic reports large financing arrangements involving Amazon, Google and Broadcom, including a Broadcom lease arrangement and potential lending tied to rent. Meyer calculates that named contracts total about $637 billion, while a separate sum based on categories in the notes is about $850 billion. These are his calculations, not a stated total in the filing; he contrasts them with reported cash of $131.7 billion and contracted future revenue of $10.8 billion.
Meyer also says the filing reports an $80.7 billion loss associated with certain transactions and argues that gross margin is less visible because compute costs are presented outside the income statement’s gross-profit line. The analysis points to executive compensation provisions in which the IPO is the sole performance test, rather than revenue, share-price or safety targets. Those characterizations should be read against the full filing and its accounting notes.
Who decides after the IPO
A vote that cannot decide anything
How one founder share, a self-selecting trust and a fixed 49.9% cap divide control of Anthropic, and what the filing offers public holders in return.
Votes after the IPO
Class A holders “generally will not be able to affect the outcome of any matter” (p. 108). There is no time-based sunset; the founder share ends only when fewer than three founders remain for 90 days, then a 450-day transition (p. 305).
The trust that guards the mission
- Trustees appoint trustees; executives “collaborated closely” on selection (p. 245)
- Paid $400,000 a year each; company funding of $8.4M in 9M 2026 (pp. 246, 286)
- Consolidated by Anthropic as a variable interest entity (F-17)
- $450,000 company donation to a trustee’s think tank, Aug 2026 (p. 247)
- 80% of board + 80% of trustees can amend or end its powers, no public vote (p. 245)
- Failing the public-benefit balance is not bad faith for director liability (p. 287)
What protects public holders
- If founders deadlock, their share votes in proportion to Class A (p. 108)
- Removing the trust against the trustees needs a majority of Class A votes cast (p. 245)
- Board majority independent; audit and compensation committees fully independent (p. 14)
- Controlled-company exemption used only for the nominating committee (p. 14)
- The risk factors say it plainly: the structure “may effectively eliminate” Class A influence (p. 17)

The governance provisions matter because buying Class A shares would not, under the structure described in the preliminary filing, give investors voting control proportionate to their investment. Class A voting power is capped at 49.9%, while a founder-held share retains a majority. That limits public shareholders’ ability to determine outcomes on matters put to a vote, even if their economic ownership grows.
The trust is presented as a mechanism to protect Anthropic’s public-benefit mission, but Meyer highlights provisions that raise questions about its independence and accountability. The filing says trustees select successors and that trust members and company executives have worked together on trustee recruitment. It also describes company payments to the trust and a company contribution to a think tank run by a trustee. These disclosures do not by themselves establish improper conduct; they help investors evaluate how the mission safeguard is structured and who oversees it.
The financing and accounting disclosures also affect how readers interpret the company’s scale and financial exposure. Supplier support can help fund computing infrastructure, but commitments and future revenue are not interchangeable measures. Understanding where costs appear in the accounts, and what is included in a loss figure, is necessary before drawing conclusions about profitability or the resources available to meet future obligations.

Inside the Draft Offering Document
The source article describes Meyer’s piece as a follow-up to an earlier overview of Anthropic’s S-1. It says the analysis checks claims against page references in the October 26 preliminary prospectus, while identifying when totals are Meyer’s own arithmetic. The filing is a registration statement, not a final account of terms that have already taken effect in a public listing.
Anthropic is the company behind Claude. Meyer discloses that Claude helped research his article and says he treated this as a conflict, tying critical points and points favorable to Anthropic to filing pages. That disclosure is relevant when weighing the analysis, but the company filing remains the underlying source for the provisions discussed here.
The filing also describes Anthropic as a public benefit corporation and sets out a Long-Term Benefit Trust with a role in board selection. The stated framework includes qualitative public-benefit reporting rather than a requirement to measure performance against an objective third-party standard. Meyer’s argument is that the practical details of those arrangements—not only the mission language—are relevant to prospective shareholders.
“The founders’ voting power is “not permanent.””

Questions the Draft Leaves Open
The source material does not establish whether Anthropic has completed an offering, when shares might begin trading, or what final pricing and share terms would be. As a preliminary S-1, the document may be revised. The analysis also does not provide enough detail to independently reconcile every supplier commitment or determine the timing and conditions attached to all of them.
Meyer’s contract totals and comparison of commitments with cash and contracted revenue are author calculations. They should not be mistaken for a single liability figure reported by Anthropic: contracts can differ in duration, conditions and accounting treatment. The source material also does not provide a full independent assessment of the company’s accounting choices, trust operations or the practical effect of its public-benefit structure.
The article says the filing discusses customers who broke Anthropic’s rules and models that gained access to real systems, but the supplied excerpts do not give full detail on the incidents, their frequency or their consequences. Those disclosures signal risks the company identifies; they do not by themselves establish the likelihood or scale of future harm.
Revisions Before Any Listing
The next step to watch for is a revised registration statement or other public filing that clarifies the offering’s status, terms and financial disclosures. If Anthropic proceeds with a listing, investors will be able to compare later versions with the October 26 preliminary prospectus, including any updates to the share structure, supplier arrangements, risk factors and executive compensation.
Readers assessing the document can check the cited sections directly rather than relying on summary totals alone. The questions raised by Meyer’s analysis are likely to remain relevant through any offering process: how voting control is allocated, how the trust’s independence is maintained, how large commitments are defined, and how Anthropic presents computing costs and public-benefit performance. The source material does not specify a timetable for further filings.
