Founders and current/former employees (collective) Anthropic is privately held. Forbes reporting on a January 2025 cap‑table review estimated that each of the seven co‑founders (Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah) still owned more than 2% of the company after multiple funding rounds, down from more than 6% each in 2023, implying that the founding team collectively controls well into double‑digit percent equity, though exact figures are not public. In addition, Anthropic runs a broad employee equity program; in May 2025 it launched its first staff share buyback at a $61.5B valuation, allowing eligible current and former employees to sell up to 20% of their holdings, which indicates that non‑founder employees as a group also own a meaningful stake, but no precise percentage has been disclosed. | Founder | — | — | May 2025 |
Amazon.com, Inc. Amazon began investing in Anthropic in 2023 via a commitment of up to $4B, including a $1.25B initial tranche and a $2.75B follow‑on in March 2024, in exchange for a minority equity position and a deep commercial partnership making AWS Anthropic’s primary cloud. In November 2024 Anthropic and Amazon announced a further $4B investment, taking Amazon’s total committed capital to about $8B while explicitly stating that Amazon remains a minority shareholder and Anthropic’s primary cloud and training partner. Amazon’s 2025 SEC filings valued its Anthropic stake at roughly $13.8B after part of the investment converted from notes into equity, and sell‑side analysts at Roth Capital have estimated that this corresponds to approximately a mid‑teens percentage ownership (on the order of 15–19%) at Anthropic’s $183B valuation, although the exact equity percentage has not been publicly confirmed. | Corporate | — | — | Sep 2025 |
Alphabet Inc. (Google) Google became Anthropic’s first major strategic investor in early 2023, reportedly paying about $300M for an initial 10% stake and agreeing that Google Cloud would host Anthropic’s workloads. Subsequent arrangements added up to roughly $2B of total committed capital by late 2023, and a further investment of about $1B was reported in January 2025, bringing Google’s total Anthropic investment to roughly $3B tied to a long‑term cloud partnership. Public reporting based on regulatory filings indicates that Google’s ownership is capped around 15% and that it currently holds roughly a low‑teens percent economic stake (variously estimated at about 12–14%), structured as non‑voting shares with no board or board‑observer seat, so its voting power is effectively 0% despite being one of Anthropic’s largest outside owners. | Corporate | — | 0.0% | Mar 2025 |
NVIDIA Corporation In November 2025 Anthropic, Microsoft and NVIDIA announced a three‑way strategic partnership under which NVIDIA will invest up to $10B in Anthropic as part of a new financing that values the company around $350B, while Anthropic commits to buy up to one gigawatt of compute capacity built on NVIDIA’s Grace Blackwell and Vera Rubin systems. The investment will be funded over time and is tied to future compute purchases, so exact equity and voting percentages have not yet been disclosed, but given its size relative to the stated valuation, NVIDIA is expected to become one of Anthropic’s larger single institutional shareholders once this round is fully closed and converted into equity. | Corporate | — | — | Nov 2025 |
Microsoft Corporation As part of the same November 2025 transaction, Microsoft agreed to invest up to $5B in Anthropic while Anthropic committed to purchase about $30B of Azure cloud capacity and to make its Claude models broadly available on Microsoft’s Azure AI and Copilot platforms. The deal terms indicate that this capital will be deployed alongside NVIDIA’s as part of Anthropic’s next financing round; at the indicated ~$350B valuation, Microsoft’s eventual equity stake is expected to be in the low‑single‑digit percentage range, making it a significant but non‑controlling shareholder, though neither Anthropic nor Microsoft has published a precise ownership figure. | Corporate | — | — | Nov 2025 |
ICONIQ Capital ICONIQ Capital led Anthropic’s $13B Series F round announced in September 2025, which valued the company at $183B post‑money and is one of the largest venture rounds ever raised by an AI startup. As lead investor writing a substantial portion of that $13B check and also reportedly heading an earlier $5B round that valued Anthropic around $170B, ICONIQ is widely viewed as one of Anthropic’s largest late‑stage institutional shareholders, though no specific percentage ownership has been disclosed. | Institutional | — | — | Sep 2025 |
Fidelity Management & Research Company (Fidelity Investments) Fidelity first invested in Anthropic in the March 2025 $3.5B Series E round and then co‑led the $13B Series F at a $183B valuation in September 2025, alongside ICONIQ and Lightspeed. In addition, funds managed by Fidelity bought a portion of FTX’s former 8% Anthropic stake in a 2024 secondary transaction. Taken together, these primary and secondary purchases make Fidelity one of the most significant institutional owners of Anthropic equity, but its exact percentage holding has not been made public. | Institutional | — | — | Sep 2025 |
Lightspeed Venture Partners Lightspeed has been one of Anthropic’s key growth‑stage backers, leading the $3.5B Series E round announced in March 2025 (at a $61.5B post‑money valuation) and then co‑leading the $13B Series F at a $183B valuation in September 2025. Given its role as lead and co‑lead in successive mega‑rounds, Lightspeed is believed to hold a substantial low‑single‑digit percentage stake in Anthropic, although specific ownership and voting percentages are not disclosed in public filings. | Institutional | — | — | Sep 2025 |
Menlo Ventures Menlo Ventures first invested in Anthropic’s $450M Series C in 2023, then led an unusual approximately $750M Series D round in early 2024 that valued the company around $15–18B, and later participated again in the $3.5B Series E led by Lightspeed. Menlo’s repeated role as a lead and major participant across multiple early growth rounds, plus its close strategic partnership with Anthropic via the $100M "Anthology" fund, suggests it retains a meaningful but undisclosed equity stake that likely sits in the low‑single‑digit percent range after subsequent dilutive financings. | Institutional | — | — | Mar 2025 |
ATIC Third International Investment Company (aligned with Mubadala Investment Company, UAE) ATIC Third International Investment Co., an investment vehicle associated with Abu Dhabi’s sovereign wealth fund Mubadala, emerged as the largest buyer in the FTX bankruptcy estate’s sale of its Anthropic shares in 2024, agreeing to acquire nearly $500M of stock out of an $884M secondary sale that represented about two‑thirds of FTX’s original 8% stake. While the precise post‑sale percentage ownership for ATIC has not been disclosed, the size of this secondary purchase makes it one of Anthropic’s more significant individual shareholders from that earlier investor syndicate, albeit subsequently diluted by later primary rounds. | Government | — | — | Mar 2024 |
Jane Street Group, LLC Quantitative trading firm Jane Street has built its Anthropic position through both secondary and primary investments. In the 2024 FTX estate sale it agreed to buy roughly $100M of Anthropic shares (plus an additional personal purchase by a senior Jane Street executive), making it the second‑largest buyer in that auction after ATIC. Jane Street later appeared as an investor in Anthropic’s March 2025 $3.5B Series E and the September 2025 $13B Series F, further increasing its exposure. Collectively, these stakes are widely viewed as material, though Anthropic has not disclosed Jane Street’s exact ownership percentage. | Institutional | — | — | Sep 2025 |
Qatar Investment Authority (QIA) Qatar’s sovereign wealth fund, the Qatar Investment Authority, was named among the significant participants in Anthropic’s $13B Series F fundraising at a $183B valuation, following earlier reports that Gulf sovereign funds were competing to back the company’s large late‑stage rounds. The size of QIA’s individual check has not been made public, but its inclusion in a very concentrated list of large institutional, private‑equity and sovereign investors in that round suggests a meaningful but undisclosed minority stake. | Government | — | — | Sep 2025 |
GIC (Government of Singapore Investment Corporation) Singapore’s sovereign wealth fund GIC also invested in Anthropic’s $13B Series F financing, as disclosed in Anthropic’s and third‑party announcements listing the major participants in that round. Together with other large asset managers and sovereign funds, GIC’s investment makes it one of the notable government‑backed shareholders of Anthropic, although no specific equity or voting percentage has been released. | Government | — | — | Sep 2025 |
