Who Owns Anthropic? Google Holds 14% With No Votes, and a Trust Elects the Board

Two different questions, two different answers

Most ownership questions have one answer. Anthropic has two, and conflating them is why almost everything written about the company's ownership errs in one direction or the other.

The first question is economic: who is entitled to the value if Anthropic is sold or listed? That is the cap table, and it is dominated by Google, Amazon, the founders, current and former employees, and a long queue of venture, crossover and sovereign investors.

The second question is about control: who picks the directors who hire and fire the chief executive? At an ordinary startup those are the same people. At Anthropic they are deliberately separated. The company is a Delaware public benefit corporation, meaning its directors are required by its charter to balance shareholder returns against a stated public mission. On top of that, it created an independent trust and gave it a share class whose only function is electing directors.

Google's 14% buys economics and nothing else. It carries no votes, no board seat and no observer rights.

The Long-Term Benefit Trust and Class T stock

At its Series C round Anthropic created a share class called Class T common stock, held only by the Long-Term Benefit Trust. Class T carries no meaningful economics. Its purpose is to give the Trust the power to elect and remove a growing number of the company's directors, on a schedule tied to time and to funding milestones - beginning with one seat and rising, on the company's own description, to a majority of the board. anthropic.com

The Trust is composed of five trustees selected for independence rather than investment: the arrangements are designed so that trustees hold no financial interest in the company. Trustees have rotated since 2023. As disclosed by the company, the group has included Neil Buddy Shah of the Clinton Health Access Initiative as chair, Richard Fontaine of the Center for a New American Security, Mariano-Florentino Cuéllar of the Carnegie Endowment for International Peace, and former Federal Reserve chair Ben Bernanke, who joined in July 2026. anthropic.com

The structure is not absolute. Anthropic has described failsafe provisions allowing the arrangement to be amended without trustee consent if sufficiently large supermajorities of stockholders agree, with the required supermajority rising as the Trust's powers grow. The Trust is durable but not untouchable, and the exact thresholds have never been published. corpgov.law.harvard.edu

How the pieces fit together

Who actually put the money in

Anthropic has never published a cap table. What exists instead is a trail of announcements, one antitrust disclosure and one set of audited filings. Together they give a reliable picture of committed capital even though they do not give exact percentages.

Sources: Anthropic funding announcements, US antitrust filings reported in 2025, Amazon's 2025 annual report, and the FTX estate's bankruptcy sale disclosures. anthropic.com · cnbc.com

These are announced commitments, not cash deployed, and not ownership shares. The Google and Amazon bars include tranches conditional on milestones or spread over years; the Series G bar is a single closed round. Committed capital and ownership percentage are different things, and at Anthropic they diverge sharply.

The one percentage that is actually documented

Ownership percentages at private companies normally circulate as rumour. Google's did not. Court documents produced in the US antitrust litigation against Google, reported in 2025, put Alphabet's holding at about 14% of Anthropic, with no voting rights, no board seat and no board observer rights, and with Google contractually restricted to a maximum of 15%. computing.co.uk

That is an unusually clean data point, and the most useful anchor for reasoning about the rest of the cap table. It also explains a structural choice: a stake that size held with votes would raise merger-control questions in several jurisdictions. Held without votes, it is an investment rather than a controlling interest.

In April 2026 Google announced it would commit up to $40bn more - reported as roughly $10bn in cash at a $350bn valuation with a further $30bn conditional on performance milestones, alongside five gigawatts of dedicated TPU capacity from 2027. techcrunch.com

Amazon: the position hiding in a 10-K

Amazon's stake is the best-documented private holding in the sector, because Amazon is a public company and has to mark it. Its annual report for the year to 31 December 2025 carried the non-voting preferred stock at approximately $14.8bn, estimated the fair value of its convertible notes at approximately $45.8bn, and recorded an associated pre-tax unrealised gain of $39.5bn. sec.gov

Two things follow. A meaningful part of Amazon's exposure is debt that converts, not stock it holds today, so its eventual percentage depends on conversion terms nobody outside the deal has seen. And Amazon's own accounting is now the closest thing the public has to a mark-to-market valuation of Anthropic between funding rounds. In April 2026 Amazon said it would invest up to a further $25bn as part of a wider infrastructure arrangement. cnbc.com

The circularity problem

Three of Anthropic's largest backers are also three of its largest suppliers. Microsoft invested $5bn in November 2025 in the same announcement in which Anthropic committed to buy at least $30bn of Azure capacity. Nvidia committed up to $10bn alongside Anthropic's commitment to take up to a gigawatt of Grace Blackwell and Vera Rubin systems. Google's April 2026 commitment is explicitly part cash and part compute. microsoft.com

This matters to an ownership analysis for a plain reason: when the investor is also the vendor, the headline investment number and the net economic transfer are not the same thing. Some of the capital returns to the investor as revenue. Ownership acquired per announced dollar is therefore not comparable across these deals, and any total that simply adds the announcements together - including the chart above - overstates how much independent outside money has gone in.

When the investor is also the vendor, the headline number and the economic transfer are not the same thing.

What is documented, and what is not

Any article that gives you a precise pie chart of Anthropic's ownership is inventing most of it. Outside Google's 14% and Amazon's balance-sheet figures, the percentages are not in the public record. That is a normal condition for a private company - and it is about to end.

The IPO will settle it

Anthropic told investors its annualised revenue run rate passed $65bn in July 2026, a figure widely reported the following month. cnbc.com The company has confidentially filed for a listing, with reporting pointing to a debut as early as autumn 2026.

A registration statement is the document that ends the guessing. An S-1 must disclose every holder of more than 5% of a voting class, the terms of each class of stock, the identity and powers of any party holding special director-election rights, and the risk factors that flow from all of it. If the Trust's arrangements survive into a listed company, they will be described there in enforceable detail for the first time. If they are modified before listing, that will be visible too.

Key takeaways

Final word

Anthropic is the clearest case in modern corporate structuring of a company answering "who owns you?" and "who controls you?" with two different names on purpose. Whether that separation survives a public listing is the most consequential unanswered governance question in the industry.
