Dario Amodei told JPMorgan Chase CEO Jamie Dimon on Friday that Anthropic set aside 5% of the company in a public benefit fund because AI could produce “enormous growth” alongside “concentration of wealth”. He spoke at a fireside chat that Yahoo Finance streamed live from about 17:03 UTC on 13 November, five days before Anthropic’s IPO is expected to price.
Anthropic’s S-1/A says it contributed 846,840,960 shares of Class N common stock to the fund. At the IPO’s $70 to $78 range that stake is worth $59.3 billion to $66.1 billion, by our arithmetic, more than the $57.75 billion to $64.35 billion the base offering of 825,000,000 shares would raise.
Business Pill · IPO Float
A short explainer on IPO float, the share of a company sold in its listing. It teaches the general idea and does not discuss Anthropic’s offering or its fund.
The key insight: As we read it, Amodei pitched the fund to IPO buyers as an answer to wealth concentration, and the S-1/A sizes that answer: 846,840,960 non-voting shares, worth $59.3 billion to $66.1 billion at the range, by our arithmetic, with a board framework to add up to 2% more each time the stock rises 50%.
Dimon raised the fund about 31 minutes into the stream, saying it was something “a lot of us are probably not really familiar with”. Amodei answered: “we decided to take 5% of the company and put it in what we call a public benefit fund”.
He said the fund comes on top of “pledges that the co-founders have made to donate 80% of their wealth”, and of a program, run “since the beginning of the company”, under which the company matches shares that employees donate to charity.
On why: “there really is a worry that because so much of that new wealth is coming from this one singular technology represented by a few companies, that we could have a world where there’s enormous growth, but at the same time there’s concentration of wealth”. He said Anthropic wants to “do everything we can to counter that concentration of wealth”.
He did not name the fund’s first uses. “We’re trying to figure out what the best problems to solve are with the public benefit fund”, he said, citing as examples “making sure that the labor transition with AI goes well” and “things like biosecurity”.
The value of the 846,840,960 Class N shares Anthropic contributed to its Public Benefit Fund, against the base offering of 825,000,000 Class A shares, at the $70 and $78 ends of the S-1/A range. Values are our arithmetic and notional; the IPO has not priced.
What the S-1/A Says About the Fund
The S-1/A filed on 10 November says Anthropic contributed 846,840,960 shares of Class N common stock, “representing 5% of our fully diluted shares as of June 30, 2026”, assuming full conversion of the Amazon notes, to Anthropic Public Benefit Fund, LLC, a wholly owned subsidiary.
Class N shares have no voting rights, except as otherwise required by law, the filing says; our explainer on non-voting stock covers the class. The fund’s shares “may be transferred or donated to a third party, or otherwise sold in a registered public offering or private placement transaction”.
The board has also approved a framework to add up to 2% of then-outstanding shares each time the share price rises 50% above the prior milestone, starting from the IPO price. A milestone counts only when the closing price has exceeded the threshold on at least 90 of the trailing 120 trading days, and any contribution is at the board’s discretion.
The board decides allocations until it approves a governance structure for the fund; the initial managers are Dario Amodei, Daniela Amodei, Jack Clark and Dr. Neil “Buddy” Shah, the filing says.
The S-1/A’s top-up framework: up to 2% of then-outstanding shares each time the stock rises 50% above the prior milestone, at the board’s discretion. Milestones from the $74 midpoint of the range are our arithmetic and illustrative; the IPO has not priced.
The 80% Pledge in the Filing
Amodei described the co-founders’ pledge as 80% of their wealth. The S-1/A words it as a pledge “to dedicate 80% of their personal equity in Anthropic to philanthropic causes”.
The filing adds that these commitments are “voluntary, revocable expressions of each co-founder’s philanthropic intent and do not constitute legally binding obligations”. It also describes the donation matching program Amodei mentioned, through which employees can pledge part of their equity awards to charity.
The Fund Against the IPO
At $70 a share the fund’s 846,840,960 shares are worth $59.3 billion; at $78, $66.1 billion, by our arithmetic. The base offering sells 825,000,000 Class A shares, $57.75 billion to $64.35 billion at the same prices, so the fund holds about 2.6% more shares than the IPO sells, by our arithmetic.
That value is notional: the fund’s Class N shares are not part of the offering, and the filing gives no schedule for selling or donating them. Pricing is expected on 18 November and trading on 19 November, per Anthropic’s IPO website filed with the SEC.
The Structural Read
As we read the filing, the fund is built to grow with the share price: each 50% rise above the prior milestone can add up to 2% of then-outstanding shares, at the board’s discretion, so a rising stock would also raise the fund’s claim on the company.
As we read the two accounts, the pledge Amodei called 80% of the co-founders’ wealth is narrower in the filing, 80% of their personal equity in Anthropic, and the filing calls it voluntary and revocable.

“do everything we can to counter that concentration of wealth”
Three Implications
FOR THE SHARE COUNT The fund’s 846,840,960 Class N shares were 5% of fully diluted shares as of 30 June 2026, assuming conversion of the Amazon notes, per the S-1/A.
FOR THE STOCK At a $74 midpoint, the first three milestones would be $111.00, $166.50 and $249.75, by our arithmetic; each can add up to 2% of shares at the board’s discretion.
FOR THE TIMELINE Pricing is expected on 18 November and trading on 19 November, per Anthropic’s IPO website filed with the SEC.
The framework describes a Barbelled Distribution Economy in which “value concentrates at the extremes (massive-scale platforms and deep-niche specialists); the middle hollows out”.
As we read it, Amodei’s worry about wealth from “a few companies” is the platform end of that barbell, and the fund is Anthropic’s stated attempt to share it. The framework predates the fund and does not discuss it.
What Is Not Established
The quotes are from our own recording of Yahoo Finance’s stream, transcribed by machine and checked against a second, larger transcription model for the passages quoted; timestamps are minutes into that recording. Amodei gave no figures for the fund beyond 5%, and no date for its first grants.
The dollar values use the filing’s price range and are not a market price; the IPO has not priced. We did not contact Anthropic for this piece. Amodei’s answer on compute in the same conversation is in our piece on the compute dilemma.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Amodei told Dimon the 5% public benefit fund is meant “to counter that concentration of wealth” from AI. The S-1/A puts 846,840,960 non-voting shares in it, worth $59.3 billion to $66.1 billion at the IPO range, by our arithmetic, more than the base offering would raise, and calls the founders’ 80% pledges revocable.
A note on sourcing. The quotes are from our own recording of Yahoo Finance’s YouTube live stream of the Amodei and Dimon fireside chat on 13 November 2026, which began at about 17:03 UTC and ran about 37 minutes; we transcribed it with faster-whisper and re-checked the quoted passages with a larger model. Timestamps are minutes into that recording. The share counts, the 2% framework, the managers, the pledge wording and the price range are from Anthropic’s S-1/A filed with the SEC on 10 November 2026; the pricing and trading dates are from Anthropic’s IPO website, filed with the SEC as a free writing prospectus. The dollar values and ratios are our arithmetic. Anthropic was not contacted for this piece.
