Who Owns Anthropic? Major Shareholders, Founder Control and the $26 Billion Private Placement

No single company owns Anthropic. As of November 12, 2026, Anthropic is a public benefit corporation controlled by its seven co-founders: the one Class F share held by their Founder LLC carries 50.1% of the general vote, and the Long-Term Benefit Trust elects a majority of the board. Economic ownership is spread across many holders.

The seven co-founders together hold about 1.70 billion shares, roughly 13% of the shares outstanding after the offering. Amazon and Google each own more than 5% in non-voting stock. Employees and other investors hold the rest, and public Class A shareholders join them after the IPO.

Key Takeaways

• No single company owns Anthropic, a public benefit corporation with about 13.09 billion shares outstanding after the offering.
• The co-founders' single Class F share carries 50.1% of the general vote, and the Long-Term Benefit Trust elects a majority of the board.
• The seven co-founders hold about 1.70 billion shares together, roughly 13% of the shares outstanding after the offering.
• Amazon and Google each hold more than 5% in non-voting Class N stock, and the S-1 gives no exact percentage for either.
• Seven companies are buying $26.0 billion of Class N stock at the IPO price, led by Google and NVIDIA at $10.0 billion each.
• Public Class A shareholders can hold at most 49.9% of the vote combined.

Why is owning Anthropic different from controlling it?

Owning Anthropic shares and controlling Anthropic are separate things, because the company has several classes of stock with different rights. Economic ownership follows the share count. Control follows two special shares, Class F and Class T. The second amended S-1 shows this structure after the offering:

• Class A, 7,427,991,791 shares. This is the stock sold in the IPO. Each share has one vote, but all Class A shares together are capped at 49.9% of the vote.
• Class N, 5,658,680,800 shares. Non-voting stock. Amazon's and Google's holdings sit here, and a Class N share converts to Class A only when it is sold to an unrelated third party.
• Class F, 1 share. Held by Founder LLC, the co-founders' vehicle. It carries 50.1% of the general vote.
• Class T, 1 share. Held by the Long-Term Benefit Trust. It elects a majority of the board of directors.
• Class E, no shares outstanding.

That adds up to 13,086,672,593 shares outstanding after the offering and the concurrent private placement. Multiplied by the IPO price, that count gives Anthropic's market cap. The two single shares carry almost none of the economic value, yet they decide who controls the company.

Who are Anthropic's largest shareholders?

Anthropic's largest disclosed shareholders are its seven co-founders, Amazon, Google and the Anthropic Public Benefit Fund. The principal stockholder table in Anthropic's S-1 lists each co-founder by name, and the filing says Amazon and Google will each hold more than 5% of the capital stock after listing. No venture capital firm reaches the 5% line.

The seven co-founders

Each co-founder beneficially owns between about 240.6 million and 244.2 million shares. The figures are as of September 30, 2026 and include stock options and restricted stock units that become available within 60 days.

• Dario Amodei: 240,637,980 shares
• Daniela Amodei: 241,408,940 shares
• Tom Brown: 244,173,040 shares
• Jack Clark: 242,271,840 shares
• Jared Kaplan: 242,351,170 shares
• Sam McCandlish: 243,383,850 shares
• Christopher Olah: 242,882,420 shares

Together that is 1,697,109,240 shares, about 13.0% of the shares outstanding after the offering. Dario Amodei also votes another 4,621,120 shares under proxies from donor-advised funds, which brings his voting total to 245,259,100 shares. He does not own those proxy shares.

Each co-founder is selling 3,378,378 shares in the IPO, about 1.4% of each holding. The seven sales add up to 23,648,646 shares, which is every share offered by selling stockholders.

Amazon

Amazon will own more than 5% of Anthropic's capital stock after listing, held in non-voting Class N shares. Much of its position comes from convertible notes, with $6.2 billion of principal outstanding as of June 30, 2026, that convert at the IPO.

The conversion is subject to a 12% ownership cap, which Amazon can waive. Anything above the cap becomes rollover notes that convert quarterly after listing, so Amazon's percentage will keep changing after the IPO. Under its 2026 purchase agreement, Amazon can invest up to $20.0 billion, of which $15.0 billion remained after the Series H round.

Google

Google will also own more than 5% after listing, again in non-voting Class N shares. Its ownership is capped at 14.99% of fully diluted shares, a limit Google can elect to relax.

Google's 2026 purchase agreement allows up to $30.0 billion, with $20.0 billion remaining after Series H. Its $10.0 billion in the concurrent private placement counts toward that amount, which leaves $10.0 billion.

The S-1 does not state an exact ownership percentage for Amazon or Google. Outside estimates vary widely, so this article does not quote one. Both companies are also Anthropic's cloud providers and sales channels, and the money side of that relationship is covered in our guide to Anthropic's revenue and cash burn.

Anthropic Public Benefit Fund

The Anthropic Public Benefit Fund holds 846,840,960 shares, which makes it one of the largest holders named in the filing.

Venture investors

No venture capital firm appears in the principal stockholder table with 5% or more. The venture rounds that built the company are traced in our guide to Anthropic's valuation and funding rounds.

Who is buying in the $26 billion private placement?

Seven technology companies have agreed to buy $26.0 billion of non-voting Class N stock at the IPO price, in a private placement that runs alongside the IPO. Google and NVIDIA account for $20.0 billion of it. The share counts below assume the $74 midpoint.

• Google: $10.0 billion (135,135,135 shares)
• NVIDIA: $10.0 billion (135,135,135 shares)
• AMD: $2.5 billion (33,783,783 shares)
• Broadcom: $1.0 billion (13,513,513 shares)
• Micron: $1.0 billion (13,513,513 shares)
• Microsoft: $1.0 billion (13,513,513 shares)
• TSMC Partners: $0.5 billion (6,756,756 shares)

The dollar amounts are fixed, so the share counts move with the final price: about 371 million shares in total at $70 and about 333 million at $78. How that final price gets set is explained in our article on the Anthropic IPO price per share.

Three details set these shares apart from the IPO shares:

• They are Class N, so they carry no votes.
• They are not subject to the underwriters' lock-up agreements.
• Two of the purchases settle earlier commitments: Google's $10.0 billion counts toward its 2026 purchase agreement, and AMD's $2.5 billion offsets part of a prior $5.0 billion commitment.

Who controls Anthropic after the IPO?

The co-founders and the Long-Term Benefit Trust control Anthropic after the IPO. The Class F share gives the co-founders 50.1% of the general vote, against a maximum of 49.9% for all Class A holders combined. The Class T share lets the Long-Term Benefit Trust elect a majority of the board. Anthropic is also a public benefit corporation, so its directors weigh a stated public benefit alongside stockholders' interests. The details are in our walkthrough of what the Anthropic S-1 says about control.

Can the public own part of Anthropic?

Yes. The IPO offers 825,000,000 Class A shares, and anyone who receives an allocation or buys the stock after listing becomes a part-owner. Public shareholders get one vote per share, but all Class A holders together cannot exceed 49.9% of the vote. Until the first trade prints, Anthropic stock is not public yet.

• Before listing: request an allocation through a participating broker, as described in how to buy the Anthropic IPO.
• After listing: buy Class A shares on Nasdaq under the ticker covered in our ANT stock guide.

MEXC View: Read the Vote Column Before the Share Column

In our view, "who owns Anthropic" has two answers, and most headlines give only one. By share count, ownership is spread out: the co-founders hold about 13%, Amazon and Google each hold more than 5%, and public Class A holders join after the IPO. By votes, it is concentrated: one Class F share carries 50.1%, and one Class T share elects the board majority.

That split is the part we would want every reader to understand before the listing. Class A buyers get economic exposure with a capped say, because all public shareholders together can reach at most 49.9% of the vote.

We also think Amazon's stake is the figure most likely to change after the IPO, since its rollover notes keep converting quarterly while the S-1 gives no exact percentage today.

We take no view on whether this structure is good or bad for shareholders. The S-1 sets out the trade-offs in its own risk factors, and that is where any change will show up first.
