Anthropic's IPO filing gives seven cofounders 50.1% voting control through a single Class F share
Anthropic's public S-1, filed October 26 under ticker ANT, routes 50.1% of shareholder votes to its seven cofounders via one non-economic Class F share, while a separate trust elects most directors, leaving public Class A holders with economic exposure but limited say.

Reach: not measured yet
A Founder LLC holds one Class F share that carries 50.1% of votes on general matters but no economic rights. Each founder owns only about 2% of the company economically and can give away up to 98% of their stake while keeping their vote. The seven founders direct the LLC by majority vote. A founder can be removed for leaving, dying, selling too many shares or for cause. The arrangement begins to sunset only once two or fewer founders remain. [2] [3] [4] [7]
Control is split across three layers. The founders hold the Class F vote. A Long-Term Benefit Trust of five financially disinterested trustees, including Ben Bernanke, Richard Fontaine and newly added Harvard astrophysicist Christopher Stubbs, elects a majority of directors. An employee share class breaks ties on certain matters. The founder share follows Palantir's 2020 IPO structure but puts control in a group rather than a single founder, unlike Meta, Snap or SpaceX. [7] [8] [2] [12]
The filing reports $16.3B in first-half 2026 revenue, a $693M operating loss and an $80.7B net loss, most of it noncash. More than 11,900 customers spend over $100K a year and about 250 spend over $10M. The risk factors warn that the company may never become sustainably profitable and that its technology carries catastrophic or existential risks. [5]
Each founder holds about 240M shares, worth roughly $13.7–14.4B at the $58.90 Series H price. Their pledge to give away 80% of their wealth is described in the filing as voluntary and revocable. The FT frames the founders' continued unity as the bet that underpins both their wealth and their control. [9] [1]
the filing gives voting control to the founders and board elections to the trust, not to public shareholders.

Implication: Anthropic is likely to keep forgoing some products, such as image and video generation, and outside investors will have little leverage over strategy.
Executive brief
Anthropic's IPO filing gives seven cofounders 50.1% of shareholder voting power through one share of Class F stock. That share carries no economic rights, and each founder owns only about 2% of the company economically (TNW; CNBC). A founder can give away up to 98% of their stake and still vote (search-indexed CNBC/Fool reporting). Anthropic filed publicly on October 26 under the ticker ANT. It reported $16.3B in H1 2026 revenue (TechCrunch). The FT's October 28 piece is available only as a feed excerpt. Its angle is that the founders' wealth and control now depend on staying united.

Technical analysis for researchers and developers
The filing describes governance, not model architecture. Three layers of control are documented: For safety researchers, decisions on deploying or pausing models therefore sit with the founders and the trust, not with market shareholders.

The filing describes governance, not model architecture. Three layers of control are documented:
- Class F (Founder LLC): 50.1% of votes on general matters. The seven founders direct it by majority vote. A founder can be removed for leaving, dying, selling too many shares or for cause (The Star/Reuters).
- Class T (LTBT): five financially disinterested trustees, including Ben Bernanke and Richard Fontaine, who elect a majority of directors (Fortune; Reuters).
- Employee class: a tie-breaker on certain matters (TNW).
For safety researchers, decisions on deploying or pausing models therefore sit with the founders and the trust, not with market shareholders.
Claims and evidence
- Each founder holds about 240M shares, worth $13.7–14.4B at the $58.90 Series H price (Fortune).
- The 80% giving pledge. The filing calls it "voluntary, revocable" and not legally binding (Fortune).
- About $518B, roughly 80% non-cancelable, according to one outlet's reading of the S-1 (Forkast). No other reviewed outlet corroborates the figure.

- Founder stakes. Each founder holds about 240M shares, worth $13.7–14.4B at the $58.90 Series H price (Fortune). The $27–29B per founder figure assumes a roughly $2T listing. That valuation is a Wall Street estimate, not a price in the filing (Yahoo/Fortune).
- The 80% giving pledge. The filing calls it "voluntary, revocable" and not legally binding (Fortune).
- Compute commitments. About $518B, roughly 80% non-cancelable, according to one outlet's reading of the S-1 (Forkast). No other reviewed outlet corroborates the figure.
- Valuation. A May funding round valued Anthropic at $965B (TNW).
Context and prior work
- The cofounders left OpenAI to start Anthropic (FT). Anthropic is a Delaware public benefit corporation and created the LTBT in 2023 (CNBC).
- The Class F share copies Palantir's 2020 IPO structure. Unlike single-founder super-voting setups at Meta, Snap and SpaceX, control here is split across a group (TNW; Yahoo Finance).
Limitations, safety and contested findings
- The risk factors say Anthropic may never become sustainably profitable. They also say its technology carries catastrophic or existential risks (TechCrunch).
- Critics say public shareholders get little real voice (IBTimes).
- The founder count is disputed. Inc reports that one cofounder is left out of the voting group (Inc).

- The founder count is disputed. Ben Mann is widely described as a cofounder (Lenny's Newsletter). Inc reports that one cofounder is left out of the voting group (Inc). Inc's reasoning couldn't be confirmed from the reviewed sources.
Business and practitioner implications
- Investors: you would be buying revenue growth and compute exposure while governance stays with the founders and the trust.
- Enterprise buyers: product decisions are deliberately shielded from short-term market pressure.
- Competitors and partners: the large compute commitments, if accurately reported, tie Google, Amazon, Microsoft and Broadcom closely to Anthropic's growth (Forkast).

- Investors: you would be buying revenue growth and compute exposure while governance stays with the founders and the trust. The structure only starts to sunset once two or fewer founders remain.
- Enterprise buyers: product decisions are deliberately shielded from short-term market pressure. Expect Anthropic to keep avoiding some product categories, as it has with image and video.
- Competitors and partners: the large compute commitments, if accurately reported, tie Google, Amazon, Microsoft and Broadcom closely to Anthropic's growth (Forkast).
