No single person or company owns Anthropic. Ownership is split among its seven co-founders, its employees, investors like Amazon and Google, and many venture funds. The co-founders own about 10% of the company together. Amazon’s stake is capped at 12% and Google’s at 14.99%.
Control works differently. Anthropic, the company that makes Claude AI, gives most of its voting power to a Founder LLC run by the seven co-founders and the right to elect most of its board to an independent Long-Term Benefit Trust. So the biggest owners are not the ones in charge.
In this guide, I break down who owns Anthropic in November 2026, using the numbers from its IPO filing, and explain who really controls Claude.
Key Takeaways
- Anthropic’s seven co-founders each held about 231 million to 244 million shares as of September 30, 2026, or about 10% of the company combined.
- Amazon and Google are the only holders the IPO filing names above 5%, but both hold mostly non-voting shares.
- A Founder LLC holds 50.1% of the votes, and the Long-Term Benefit Trust elects a majority of the board.
- Anthropic plans to start trading on the Nasdaq under the ticker ANT on November 19, 2026.
- Anthropic owns Claude. No outside company owns the Claude product.
Who Owns Anthropic Today?
Anthropic, PBC is a public benefit corporation based in San Francisco. It was founded in January 2021 by seven former OpenAI employees, according to Wikipedia. Until its IPO, it is a private company owned by its founders, staff and investors.
Anthropic made its ownership public for the first time when it filed its S-1 registration statement on October 26, 2026. The filing lists share counts but leaves the ownership percentages blank. So the percentages below are either caps written into investor deals or estimates based on about 16.9 billion fully diluted shares.
| Owner | What They Hold | Approximate Stake |
|---|---|---|
| Seven co-founders | About 1.69 billion Class A shares | About 10% combined |
| Google (Alphabet) | Mostly non-voting Class N shares | Above 5%, capped at 14.99% |
| Amazon | Convertible notes and non-voting shares | Above 5%, capped at 12% |
| Anthropic Public Benefit Fund | 846.8 million Class N shares | About 5% |
| Venture funds, other investors and employees | Class A shares and options | The rest |
Why do the numbers look so loose? Because Amazon and Google’s exact share counts are not shown in the filing’s ownership table. What the filing does show is the cap each company agreed to.
Who Controls Anthropic If No One Owns a Majority?
Anthropic splits owning shares from voting on decisions. It does this with five classes of stock, as explained by Fortune from the S-1.
| Share Class | Who Holds It | Voting Power | Economic Rights |
|---|---|---|---|
| Class A | Public buyers, founders, early investors | One vote per share, capped at 49.9% of all votes | Yes |
| Class F | Founder LLC (one share) | 50.1% of all votes | No |
| Class T | Long-Term Benefit Trust (one share) | Elects a majority of the board | No |
| Class N | Amazon, Google, Public Benefit Fund | None, except where the law requires | Yes |
| Class E | Non-founder employees | Only on narrow Trust matters | No |
Here is what that means in plain words:
- The founders control shareholder votes. One Class F share gives the Founder LLC 50.1% of the votes, even though it has no money value.
- The Trust controls the board. One Class T share lets it elect most of the directors.
- Amazon and Google own a lot but vote very little. Their Class N shares only turn into voting Class A shares when sold to an unrelated buyer.
This kind of setup is not new. Founder-controlled companies often use special share classes, which you can read about in our guide to types of companies.
Does founder control last forever? No. According to TechCrunch, it ends ten years after the IPO, or sooner if fewer than three founders remain in the LLC. A founder stays in the LLC only while holding at least 2% of their IPO-era shares.
What Is the Long-Term Benefit Trust?
The Long-Term Benefit Trust (LTBT) is an independent group set up to protect Anthropic’s mission. Anthropic describes it as “an independent body of five financially disinterested members.” Trustees cannot hold Anthropic stock, and they serve one-year terms.
Anthropic’s stated mission is “the responsible development and maintenance of advanced AI for the long-term benefit of humanity.” As a public benefit corporation, its board must weigh that mission alongside profits.
As of October 2026, the trustees are:
| Trustee | Role |
|---|---|
| Neil “Buddy” Shah | Chair |
| Richard Fontaine | Trustee |
| Ben Bernanke | Trustee |
| Christopher Stubbs | Trustee |
Can shareholders overrule the Trust? In rare cases, yes. The Harvard Law School Forum on Corporate Governance explains that a large supermajority of stockholders can change the Trust’s rules without the trustees’ consent. This “failsafe” exists in case the structure stops working.
Who Founded Anthropic, and How Much Do the Founders Own?
Seven co-founders control Anthropic through the Founder LLC. Most of them worked at OpenAI before 2021. Here is what each one owned as of September 30, 2026, based on the S-1 table reported by Fortune.
| Co-Founder | Role | Class A Shares |
|---|---|---|
| Tom Brown | Co-founder | 244,173,040 |
| Chris Olah | Co-founder | 242,882,420 |
| Jared Kaplan | Co-founder, leads technical research | 242,351,170 |
| Jack Clark | Co-founder | 242,271,840 |
| Daniela Amodei | President and board chair | 241,408,940 |
| Dario Amodei | CEO | 240,637,980 |
| Sam McCandlish | Co-founder | 231,809,780 |
Together, that is about 1.69 billion shares, or roughly 1.4% each. These counts include options and stock units that vest within 60 days. Dario Amodei’s listed total is higher, at about 245 million, because it includes 4.6 million shares in donor-advised funds that he votes but no longer owns.
What about Ben Mann? Many sources, including Wikipedia, list Ben Mann as an eighth co-founder. The S-1 says he is “often referred to as a co-founder” but is not a member of the Founder LLC. An Anthropic spokesperson told The Next Web it is “still fair to refer to him as a cofounder.” He co-leads Anthropic Labs with Mike Krieger.
All seven co-founders have pledged to give away 80% of their personal equity. Fortune notes the pledge is voluntary and can be revoked.
Does Amazon Own Anthropic?
No. Amazon is a large minority investor, not the owner. It is one of the two holders the S-1 names above 5%. Its notes convert into non-voting Class N shares, and conversion stops at 12% of the company unless Amazon waives the cap.
According to Leverage Shares, citing Amazon’s Q2 2026 quarterly report, Amazon has put in at least $18 billion:
- $8.0 billion in convertible notes between 2023 and 2025
- $5.0 billion of Series G non-voting preferred shares in Q2 2026
- $5.0 billion of Series H non-voting preferred shares, under a deal for up to $20.0 billion
Why does Amazon invest so much? Because Anthropic is also a major cloud customer. Amazon Web Services is one of the main cloud providers Anthropic relies on. You can see how this fits Amazon’s wider strategy in our Amazon SWOT analysis, and who controls Amazon itself in who owns Amazon.
Does Google Own Anthropic?
No. Google, through its parent Alphabet, is a minority investor. Under its 2026 agreement, Google’s stake is capped at 14.99% of fully diluted shares unless it chooses to waive that cap. Like Amazon, it holds mostly non-voting Class N shares.
Google’s deals have grown fast:
| Date | Google Investment |
|---|---|
| March 2025 | The New York Times reported Google owned 14%, with no voting rights |
| March 2026 | Agreed to invest up to $40 billion in cash and performance-linked payments |
| March 2026 | $10 billion in Series G at a $350 billion pre-money valuation |
| May 2026 | $10 billion in Series H, from a $30 billion note facility |
| IPO | Option to buy up to $10 billion of Class N shares at the IPO price |
The 2025 figure was reported by Sherwood News, citing The New York Times. The 2026 figures come from Leverage Shares.
Why would Google fund an outside AI lab? Leverage Shares describes Amazon and Google as sitting on every side of Anthropic’s business: as investors, as cloud suppliers and as rivals. For more on who owns Google itself, read who owns Google.
Which Other Companies Have Invested in Anthropic?
Beyond Amazon and Google, Anthropic has a long list of backers. In November 2025, Nvidia committed up to $10 billion and Microsoft up to $5 billion. You can learn more about both companies in our lists of Nvidia competitors and Microsoft competitors.
Anthropic had raised $141.1 billion in total as of June 30, 2026. Here are its biggest recent rounds:
| Round | Date | Amount | Valuation | Led By |
|---|---|---|---|---|
| Series E | March 2025 | $3.5 billion | $61.5 billion | Lightspeed Venture Partners |
| Series F | September 2025 | $13 billion | $183 billion | ICONIQ |
| Series G | February 2026 | Not listed here | $380 billion | GIC and Coatue |
| Series H | May 2026 | $65 billion | $965 billion | Altimeter, Dragoneer, Greenoaks, Sequoia |
An earlier investor was the crypto exchange FTX, which put $500 million into a $580 million round in April 2022, according to Wikipedia. CNBC reported in March 2024 that the FTX bankruptcy estate was selling most of that stake.
Do venture funds own big chunks? Not individually. None of these funds is named above 5% in the S-1. Their stakes sit inside the large Class A pool.
Is Anthropic a Public Company?
Not yet, but it is about to be. Anthropic plans to price its shares on Wednesday, November 18, and start trading on Thursday, November 19, 2026, as reported by Yahoo Finance.
| IPO Detail | Planned Terms |
|---|---|
| Exchange and ticker | Nasdaq Global Select Market, ANT |
| Shares offered | 825 million |
| Price range | $70 to $78 per share |
| Money raised | Up to $64.4 billion at the top of the range |
| Valuation | About $1.4 trillion fully diluted at $78 |
| Lead banks | Goldman Sachs and Morgan Stanley |
| Private placement | $26 billion at the IPO price, including Alphabet, Nvidia, Microsoft and TSMC |
Will the IPO change who controls Anthropic? No. Public buyers will get Class A shares, and all Class A votes together are capped at 49.9%. The Founder LLC and the Trust keep control.
Bloomberg reported the offering was several times oversubscribed, according to StockAnalysis.
Who Owns Claude AI?
Anthropic owns Claude. Claude is Anthropic’s family of AI models and its main product. It comes in Haiku, Sonnet and Opus tiers and powers tools like Claude Code.
So the owners of Claude are the same as the owners of Anthropic. Amazon and Google do not own Claude, even though they are major investors in Anthropic.
How big is the Claude business? According to the S-1, as reported by PPC Land, Anthropic’s revenue grew like this:
| Period | Revenue |
|---|---|
| 2023 | $41 million |
| 2024 | $386 million |
| 2025 | $4.59 billion |
| First half of 2026 | $16.29 billion |
Anthropic still reported a net loss of $80.7 billion in the first half of 2026. Most of that, $72.4 billion, was a non-cash change in the value of convertible notes and similar instruments, not money spent on running the business.
Who Runs Anthropic?
Dario Amodei is the CEO, and his sister Daniela Amodei is President and chair of the board. According to Reuters, Dario’s 2025 pay was about $18 million and Daniela’s was $16.4 million, mostly in stock and options. Krishna Rao is the Chief Financial Officer.
The board, as listed by TechCrunch in October 2026, includes:
| Director | Background |
|---|---|
| Daniela Amodei | Co-founder, President, board chair |
| Dario Amodei | Co-founder and CEO |
| Reed Hastings | Netflix co-founder |
| Christopher Liddell | Former CFO of Microsoft and General Motors |
| Vas Narasimhan | Novartis CEO, appointed by the Trust in April 2026 |
| Yasmin Razavi | Spark Capital |
One seat is vacant. With Narasimhan’s appointment, Anthropic said Trust-appointed directors now make up a majority of the board. Notice who is missing: neither Amazon nor Google has a board seat.
How Does Anthropic’s Ownership Compare With Other Tech Giants?
Anthropic is unusual even among founder-led companies. At most public companies, votes follow shares. At Anthropic, the biggest economic owners hold the least voting power.
| Company | Largest Owner | Who Controls Votes |
|---|---|---|
| Anthropic | No majority owner; Google and Amazon above 5% | Founder LLC (50.1%) and the Trust (board majority) |
| Amazon | Jeff Bezos, about 8.8% | Shareholders, one vote per share |
| Walmart | Walton family, about 44% | The Walton family |
For the other examples, see who owns Walmart and who owns Apple, where a much more spread-out shareholder base sets the board.
Why would a company choose this? Anthropic says the structure protects its safety mission from short-term profit pressure. Fortune notes that it borrows ideas from other founder-controlled companies, such as Mark Zuckerberg’s Meta.
What Does Anthropic’s Ownership Mean for You?
- For Claude users: No Big Tech investor can take over Claude or change its direction alone. Day-to-day decisions sit with the founders and the board.
- For investors: Public buyers will share in profits but have limited say. Class A votes are capped at 49.9% of the total. This is not investment advice, so read the final prospectus before making any decision.
- For students: Anthropic is a clear case study in separating ownership from control, a useful idea when you study competitive advantage and corporate strategy.
Bottom Line
So, who owns Anthropic? Many people and companies do. The seven co-founders own about 10% together, Amazon and Google each own more than 5% but less than their caps, and investors and employees own the rest. Who controls Anthropic is a different answer: the Founder LLC holds most of the votes, and the Long-Term Benefit Trust picks most of the board.
For me, this is the most important lesson in the whole story. Owning a big slice of a company does not always mean you can steer it. Amazon and Google have put tens of billions into Anthropic, yet neither has a board seat or real voting power. If you want to apply this kind of thinking to other companies, start with our SWOT analysis guide.
