Anthropic Financials

The funding-round arc from the May 2021 ~$124 million Series A through the May 28, 2026 $65 billion Series H at a $965 billion post-money valuation, the cumulative Amazon and Google strategic-investment commitments and the gigawatt-scale compute partnerships they anchor, the run-rate revenue ramp from approximately $9 billion at the end of 2025 to $30 billion in April 2026 to over $47 billion in early May 2026, the November 2025 $50 billion American AI infrastructure build-out, and the June 1, 2026 confidential draft S-1 filing — every claim cited to a primary source. Anthropic is privately held, US-headquartered in San Francisco, organized as a Delaware public benefit corporation (Anthropic, PBC), with the Long-Term Benefit Trust as a governance overlay above the board.

IPO state

Confidential S-1

Confidential draft S-1 filed with the SEC on Jun 1, 2026 under Rule 135. Share count and price range not set; underwriters reportedly scheduling investor meetings for a listing as soon as Oct 2026.

Anthropic confidentially filed a draft Form S-1 with the SEC on June 1, 2026. The filing landed four days after the May 28, 2026 Series H close ($65 billion raised at a $965 billion post-money valuation, co-led by Altimeter, Dragoneer, Greenoaks, and Sequoia). The S-1 is a draft — submitted confidentially under the JOBS Act so the SEC review can run before any public Form S-1 lands — and Anthropic published the existence of the filing under SEC Rule 135, the narrow no-offer notice that lets a pre-IPO company say only that a filing has been made. The number of shares and the offering price have not been set, and Anthropic has not announced a target pricing date. Bloomberg reported on June 3, 2026 that Anthropic picked Morgan Stanley and Goldman Sachs to lead the offering, with JPMorgan also on the deal; reporting targets a fall 2026 window subject to SEC review and market conditions. On July 15, 2026 Bloomberg and CNBC reported that the banks leading the offering are scheduling investor meetings in the coming weeks, ahead of a listing that could come as soon as October 2026; the same day, The Information reported that Anthropic is in talks to add billions of dollars to a bank credit line ahead of the IPO. These process details are reported, not company-confirmed — Anthropic itself has announced only the filing.

What this changes about this page. Until the confidential S-1 converts to a public Form S-1 (which has to happen at least 15 days before any road show), the document itself is not publicly readable. The funding-rounds table, ARR trajectory, strategic-investment subsection, and named-customer roster below stay anchored on Anthropic's own news posts, the partner-side disclosures from Amazon and Alphabet, and contemporaneous reporting. Once the public S-1 lands, audited GAAP financials and disaggregated revenue / margin / customer-concentration disclosure become part of the source set, and the page absorbs them as a separate section. Once Anthropic prices and lists, the page transitions to the public-company matched-set shape used on Microsoft, Alphabet, and Oracle — EDGAR XBRL-driven headline charts, a live TradingView ticker, and an Earnings Reaction History section.

Funding rounds

Newest round first. Each row's Confirmed / Reported pill reflects whether the dollar figures come from a primary source (Anthropic's own news post or a partner press release) or from contemporaneous reporting. Click a row to expand the round's prose detail and source links. Strategic investments from Amazon and Google are listed separately below since they have flowed in multi-tranche commitments tied to compute-capacity allocations rather than discrete venture rounds.

Series H $65B at $965B post-money Confirmed

On May 28, 2026 Anthropic announced it had raised $65 billion in Series H funding at a $965 billion post-money valuation, co-led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. The valuation roughly 2.5x'd the $380 billion Series G mark from February 2026, and the proceeds were attributed to safety and interpretability research, compute expansion to meet demand for Claude, and product and partnership scaling.

Additional co-leads: Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN.

Significant investors: AMP PBC, Baillie Gifford, Blackstone, Brookfield, D. E. Shaw Ventures, DST Global, Fidelity Management & Research, General Catalyst, Insight Partners, Jane Street, Lightspeed Venture Partners, MGX, NTTVC, NX1 Capital, Situational Awareness LP, T. Rowe Price Associates, T. Rowe Price Investment Management, and Temasek.

Hyperscaler tranche. The round includes $15 billion of previously committed investments from hyperscalers, including $5 billion from Amazon announced as part of the April 20, 2026 expanded-collaboration agreement (see the strategic-investments section).

Strategic infrastructure partners. Micron, Samsung, and SK hynix participated as memory, storage, and logic-chip supply partners. Anthropic announced concurrent compute-capacity expansions with Amazon (up to 5 GW), Google and Broadcom (5 GW of next-generation TPU capacity), and SpaceX (GPU capacity in Colossus 1 and Colossus 2).

Primary source: "Anthropic raises $65B in Series H funding at $965B post-money valuation," anthropic.com news, May 28, 2026. CFO Krishna Rao is quoted in the announcement.

Series G $30B at $380B post-money Confirmed

On February 12, 2026 Anthropic announced it had raised $30 billion in Series G funding at a $380 billion post-money valuation, co-led by Coatue and GIC. Co-leads on the round also included D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, and MGX. Reporting in CNBC and Reuters noted that the term sheet had been signed at a $350 billion valuation in late December 2025 before closing at $380 billion in February 2026.

The Series G valuation roughly doubled the Series F mark from six months earlier. At the time of the Series G announcement, Anthropic also disclosed that 500+ business customers were each spending more than $1 million on an annualized basis.

Primary source: "Anthropic raises $30 billion Series G funding at $380 billion post-money valuation," anthropic.com news, February 12, 2026.

Series F ~$13B at $183B post-money Confirmed

In September 2025 Anthropic announced a Series F at approximately $13 billion raised at a $183 billion post-money valuation, co-led by Iconiq Capital, Fidelity Management & Research, and Lightspeed Venture Partners. The Qatar Investment Authority and other investors participated.

The round roughly tripled the prior post-money valuation (the March 2025 Series E at $61.5 billion) and brought sovereign-wealth-fund participation into the cap table at scale. The pace from Series E ($61.5B) to Series F ($183B) to Series G ($380B) to Series H ($965B) inside fifteen months is the load-bearing context for the cumulative-committed-capital arc on the chart below.

Primary source: "Anthropic raises $13B Series F at $183B post-money valuation," anthropic.com news, September 2025.

Series E ~$3.5B at $61.5B post-money Reported

In March 2025 Anthropic was reported to have closed a Series E at approximately $3.5 billion raised at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners. Reported participants included Bessemer, Cisco Investments, D1 Capital, Fidelity, General Catalyst, Jane Street, MGX, Salesforce Ventures, and Wellington.

Sources: Bloomberg, March 3, 2025; contemporaneous reporting in NYT, WSJ, and Reuters. Anthropic has not published a standalone Series E announcement on its news feed.

Series D / Amazon initial $1.25B with right to expand to $4B Confirmed

On September 25, 2023 Amazon announced an initial $1.25 billion investment in Anthropic with the contractual right to expand to $4 billion. The agreement included Anthropic adopting AWS as a primary cloud partner and using AWS Trainium and Inferentia chips for model training and inference. This is treated as Anthropic's Series D in the funding-round timeline; the Amazon commitment grew through a series of subsequent tranches across 2024 and 2026 covered in the strategic-investments section.

Primary source: "Amazon and Anthropic announce strategic collaboration," aboutamazon.com, September 25, 2023.

Series C ~$450M at ~$4.1B post-money Confirmed

In May 2023 Anthropic announced a Series C of approximately $450 million, led by Spark Capital, with Google, Salesforce Ventures, Sound Ventures, and Zoom Ventures participating. Post-money valuation was reported at roughly $4.1 billion. The round directly preceded the Claude 2 launch in July 2023.

Primary source: "Anthropic Series C," anthropic.com news, May 2023. Valuation figure per contemporaneous reporting in Reuters and Bloomberg.

Series B ~$580M (FTX-led) Reported

In April 2022 Anthropic raised approximately $580 million in Series B funding led by Sam Bankman-Fried's FTX and Alameda Research, with Jaan Tallinn and the Center for Emerging Risk Research participating. FTX alone reportedly invested $500 million.

FTX bankruptcy resolution. The November 2022 FTX collapse left the FTX bankruptcy estate as one of Anthropic's largest single shareholders. The estate sold the stake in two tranches in 2024 for a combined approximately $1.3 billion — a substantial recovery for FTX creditors and a one-time secondary-market liquidity event for the Anthropic cap table.

Sources: contemporaneous reporting (Reuters, NYT, Bloomberg); FTX-estate sale per Reuters, April 1, 2024. Anthropic did not publish a standalone Series B announcement on its news feed.

Series A ~$124M; valuation not disclosed Reported

In May 2021, four months after Anthropic's incorporation, the company raised approximately $124 million in its first outside round, led by Jaan Tallinn (Skype cofounder) and Dustin Moskovitz (Asana, Open Philanthropy), with the Center for Emerging Risk Research and Eric Schmidt participating. Anthropic spent its first eighteen months as a research-only operation on this funding; the first commercial Claude product did not ship until March 2023. The Series A investor list skews heavily toward the AI-safety and effective-altruism community — a deliberate choice by the founders to align early capital with the company's stated mission.

Sources: contemporaneous reporting (The Information, Bloomberg, Forbes). Anthropic has not published a standalone Series A announcement; the round's existence is attested by the company in subsequent funding posts and by named investors' own disclosures.

Valuation arc

Post-money valuation per round on a logarithmic scale, plotted chronologically from April 2022 (Series B) through May 2026 (Series H). The Series A valuation was not disclosed and is omitted.

Hollow point: reporter-coverage-only valuation

Series A (May 2021) is omitted — the round's valuation was not publicly disclosed. The Series D / Amazon-initial event (September 2023) is treated as a strategic investment with a multi-tranche cumulative commitment rather than a discrete priced round and is excluded from the valuation arc; see the strategic-investments section for the cumulative-commitment picture.

Strategic investments — Amazon and Google

The Amazon and Google commitments are larger than most peer AI labs' entire fundraising history. They have flowed in multi-tranche increments tied to compute-capacity allocations and cloud-partnership terms rather than as discrete priced rounds — the cumulative figures below combine equity investment with named compute-commitment dollar figures, and each row links to the partner press release or Anthropic news post that announced it.

Amazon

Primary cloud + training partner

  • Apr 20, 2026 — $5B new investment + up to $20B future on top of the prior $8 billion. Anthropic separately committed more than $100 billion over ten years to AWS for up to 5 GW of training and inference capacity across Trainium2 through Trainium4 chips. Source: anthropic.com news.
  • May 28, 2026 — $5B as part of Series H (the $15 billion hyperscaler-previously-committed tranche of the Series H referenced Amazon's contribution specifically).

Fair-value mark (Amazon 10-Q). As of March 31, 2026 Amazon carried its Anthropic convertible notes at a fair value of approximately $42.2 billion and its Anthropic nonvoting preferred stock at approximately $32.0 billion — roughly $74 billion combined against the $8.0 billion invested (December 31, 2025: ~$45.8 billion notes / ~$14.8 billion preferred; notes convert into preferred over time). Q1 2026 included a ~$12.3 billion upward adjustment on the preferred for observable price changes. The 10-Q also details the April 2026 up-to-$20 billion commitment as a financing facility: nothing drawable at inception, amounts unlock as AWS hits compute-capacity delivery milestones, draws are issued as new convertible notes (or common stock after a liquidity event such as an IPO), the facility expires 30 months after a liquidity event, and a separate option to invest up to $5 billion in future equity financings reduces it if exercised. Source: Amazon 10-Q for the quarter ended March 31, 2026 (filed April 30, 2026).

AWS remains Anthropic's primary cloud provider and training partner. Over 100,000 customers run Claude on Amazon Bedrock; the Claude Platform-on-AWS direct integration is rolling out in 2026.

Claude is available on Google Cloud's Vertex AI alongside the direct partnership; the Google + Broadcom TPU deal is Anthropic's "most significant compute commitment to date" per CFO Krishna Rao at the time of the announcement.

Three-cloud distribution. Claude is the only frontier AI model available on all three major cloud platforms: AWS Bedrock, Google Cloud Vertex AI, and Microsoft Azure Foundry. The Microsoft Azure Foundry availability is a distribution partnership; Microsoft is not currently a disclosed equity investor in Anthropic.

SpaceX / Colossus. Per the May 28, 2026 Series H announcement, Anthropic also signed an agreement with SpaceX for access to GPU capacity in the Colossus 1 and Colossus 2 superclusters. This is a compute-capacity supply agreement, not a separate equity investment.

Ode with Anthropic. On July 15, 2026 Anthropic, Blackstone, and Hellman & Friedman formally launched Ode with Anthropic, a standalone enterprise AI services firm (announced earlier in 2026, now under its official name) built on Fractional AI, the applied-AI services firm the venture acquired in May 2026. Alongside the founding partners, the investor consortium includes Apollo Global Management, General Atlantic, GIC, Goldman Sachs, Leonard Green & Partners, and Sequoia Capital. Ode is a joint venture, not an Anthropic subsidiary; reporting has put the venture at $1.5 billion, a figure the founding announcement itself does not carry. Source: joint press release, July 15, 2026; venture size per TechCrunch, July 15, 2026.

ARR trajectory — what Anthropic has actually disclosed

Anthropic has disclosed run-rate revenue figures at four discrete moments across the last six months. The headline shape: approximately $9 billion at the end of 2025 → $30+ billion in April 2026 → over $47 billion in early May 2026. Each snapshot is sourced to an Anthropic announcement. Anthropic has not disclosed recognized GAAP revenue, gross margin, net revenue retention, or per-customer ARR — the headline counter reflects the disclosed annualized run-rate rather than recognized revenue.

Year-end 2025 ARR

As of Dec 31, 2025

~$9B

Implied by the April 6, 2026 disclosure that ARR had grown from "approximately $9 billion at the end of 2025."

April 2026 ARR

As of Apr 20, 2026

$30B+

Per the April 20, 2026 Amazon-expanded-collaboration announcement: "Our run-rate revenue has now surpassed $30 billion."

May 2026 ARR

As of early May 2026

$47B+

Per the May 28, 2026 Series H announcement: "our run-rate revenue crossed $47 billion earlier this month."

Large-customer count

Apr 6, 2026

1,000+

Business customers each spending over $1 million annualized. Doubled from 500+ at the February 2026 Series G announcement (less than two months earlier).

The November 12, 2025 infrastructure announcement disclosed that Anthropic served more than 300,000 businesses, with the large-account count (each >$100,000 annualized) up nearly sevenfold in the prior year. The April 20, 2026 Amazon-expansion announcement disclosed over 100,000 customers running Claude on Amazon Bedrock specifically.

Compute and infrastructure commitments

The named compute-capacity commitments are the load-bearing context behind the cumulative-funding arc. Anthropic now has named gigawatt-scale agreements with three different infrastructure partners, anchored to a $50 billion American AI infrastructure build-out announced in November 2025.

$50B American AI infrastructure build-out — November 12, 2025

Anthropic committed to a $50 billion nationwide AI infrastructure build-out, starting with custom data centers in Texas and New York, developed in partnership with Fluidstack. The build-out is expected to create approximately 800 permanent jobs and 2,400 construction jobs, with sites coming online throughout 2026.

Source: anthropic.com news, November 12, 2025.

Up to 5 GW from Amazon (AWS Trainium) — April 20, 2026

More than $100 billion over ten years to AWS technologies, securing up to 5 GW of new capacity to train and run Claude. The commitment spans Graviton and Trainium2 through Trainium4 chips, with the option to purchase future generations of Amazon's custom silicon. Nearly 1 GW total of Trainium2 and Trainium3 capacity expected to come online by the end of 2026; significant Trainium2 capacity already coming online in Q2 2026.

5 GW of next-generation TPU capacity from Google and Broadcom — April 6, 2026

Multiple gigawatts of next-generation TPU capacity expected to come online starting in 2027, sited primarily in the United States. Anthropic CFO Krishna Rao called this the company's "most significant compute commitment to date" at the time of the announcement. Builds on the prior TPU usage on Google Cloud and the October 2025 TPU-capacity expansion.

GPU capacity in Colossus 1 and Colossus 2 from SpaceX — May 28, 2026

Per the Series H announcement, Anthropic signed an agreement with SpaceX for access to GPU capacity in the Colossus 1 and Colossus 2 superclusters (the xAI / SpaceX-operated Memphis facilities). This is a compute-capacity supply agreement, not a separate equity investment.

Diversified hardware strategy

Anthropic trains and runs Claude on a mix of AWS Trainium, Google TPUs, and NVIDIA GPUs, matching workloads to the chips best suited for each. Amazon remains the primary cloud provider and training partner; over one million Trainium2 chips are in use to train and serve Claude as part of Project Rainier.

The Long-Term Benefit Trust and the cap table

Anthropic's Long-Term Benefit Trust (LTBT), formed September 19, 2023, sits above the company's board as a governance overlay. The LTBT does not hold equity in Anthropic — trustees are required to be independent of the company and hold no Anthropic financial stake. The trust's powers are voting rights, not economic claims: as Anthropic crosses successive funding milestones, the LTBT gains the right to elect successively more board seats, eventually a majority. The for-profit corporation's economic upside continues to flow to venture investors and employees per ordinary cap-table mechanics.

Practically: the headline $965 billion Series H post-money valuation is the valuation of Anthropic, PBC — the Delaware public benefit corporation. The LTBT is a governance layer above the board; it does not reduce or encumber the economic value of the underlying equity. Full mechanics, including the publicly-named trustees and the phased-authority structure, are documented on the sibling Anthropic Leadership page's LTBT row.

The named-customer list above is a small visible subset of that base.

Acquisitions

Anthropic has not been an active acquirer on the same scale as Google, Meta, or even Cognition. The company has not announced any material acquisition through mid-July 2026; the public M&A footprint consists of small acqui-hires that Anthropic has chosen not to disclose formally. (Fractional AI, acquired in May 2026, was acquired by the Ode with Anthropic joint venture, not by Anthropic itself.) If a material acquisition lands in 2026 or beyond — e.g. an inference-stack-relevant chip company, a security or interpretability tools vendor, or a vertical-AI products acquisition — this section absorbs it at the next refresh.

Read these primary sources

Anthropic was private through May 2026 and had no public SEC EDGAR registration of its own until the June 1, 2026 confidential draft S-1 (which is not publicly readable during the draft phase). Various third-party SPV investors have filed Form Ds for vehicles with "Anthropic" in their names (e.g. "Anthropic Fund III Feb 2026," "Anthropic MAV Secondary Fund II," "IBD Ventures Anthropic Series O"); those are not Anthropic's own filings and the underlying terms are private.

Partner-side disclosures — Amazon and Google

Amazon names Anthropic explicitly in its quarterly 10-Q investments footnote — convertible notes and nonvoting preferred stock carried at fair value, with the mark updated each quarter. Alphabet's stake is carried inside its aggregate non-marketable equity securities and is not named in its 10-K / 10-Q filings (verified through the FY2025 10-K and the Q1 2026 10-Q). The aboutamazon.com news posts are the canonical partner-side source for the major investment tranches; Amazon's SEC filings carry the financial mark.

The active and resolved litigation docket lives on the lawsuits page; the Bartz $1.5 billion settlement is the largest cap-table-relevant judicial obligation. The Claude product / version history lives on the cross-section versions page.

Methodology & data sources

Primary-vs-reported source discipline. Every value-bearing claim on this page is labeled Confirmed (sourced to Anthropic's own news post or a partner press release) or Reported (sourced only to contemporaneous reporting from Bloomberg, CNBC, Reuters, NYT, WSJ, The Information, or similar). The In talks label is reserved for rounds and figures that have not closed and are reported as in-progress only. Reporter coverage of fast-moving private companies frequently surfaces dollar amounts and valuations the company itself has not formally confirmed; the methodology footer's first job is to keep this distinction visible at a glance.

Anthropic, PBC. The company is organized as a Delaware public benefit corporation under the legal name Anthropic, PBC. The Long-Term Benefit Trust (LTBT), formed September 19, 2023, holds voting rights above the company's board but does not hold equity. The headline post-money valuations cited on this page are the valuation of Anthropic, PBC — the LTBT is a governance overlay, not a cap-table encumbrance.

No prior SEC EDGAR filings; first registration is the June 1, 2026 confidential draft S-1. Anthropic itself has filed no Form D, no S-1, no 10-K, no 10-Q, no 8-K, and no DEF 14A under the "Anthropic" name through May 2026. SEC EDGAR full-text search for "Anthropic" / "Anthropic PBC" at efts.sec.gov returns only unrelated filers (third-party SPV investment vehicles that have "Anthropic" in their names: "Anthropic Fund III Feb 2026", "Anthropic MAV Secondary Fund II", "IBD Ventures Anthropic Series O", etc.). The June 1, 2026 confidential draft S-1 is the first direct Anthropic registration; per JOBS-Act mechanics, the document is not publicly readable while in confidential draft form, and the SEC review proceeds before any public Form S-1 lands ahead of the road show.

Revenue and ARR. Anthropic has disclosed run-rate revenue at four discrete moments across the last six months — approximately $9 billion at the end of 2025 (implied by the April 2026 disclosure), $30+ billion in April 2026 (per the Amazon-collaboration post), and over $47 billion in early May 2026 (per the Series H announcement). Anthropic has not disclosed recognized GAAP revenue, gross margin, net revenue retention, per-customer ARR, or per-product revenue splits. The headline ARR counter and the ARR trajectory section surface the disclosed annualized run-rate figures rather than recognized revenue. The public Form S-1 will almost certainly disaggregate revenue; the page absorbs that disclosure when it lands.

Strategic-investment cumulative-commitment framing. The Amazon and Google commitments include both equity investment and named compute-capacity dollar figures. The cumulative numbers in the strategic-investments section combine those streams because the partner-side announcements consistently bundle them together. Where the equity portion is separable, the row prose surfaces it explicitly.

Page-shape evolution. This page ships in the private-company shape (matched-set with Cognition and xAI). When the confidential S-1 converts to a public Form S-1, the audited GAAP financials become part of the source set and a new section absorbs them. Once Anthropic prices and lists publicly, the page transitions to the public-company matched-set shape used on Microsoft, Alphabet, Oracle, and the rest of the public-company financials surfaces — EDGAR XBRL-driven headline charts, live TradingView ticker, Earnings Reaction History section.

What's intentionally not here. Computed valuation deltas / round-over-round multiples (the page surfaces the rounds and lets visitors do the math). Secondary-market estimates (the 2024 FTX-estate sale of the Series B stake is mentioned for context but no secondary-market chart is rendered). The "Anthropic stake as a fraction of Amazon's or Alphabet's quarterly AI profits" derived ratio that Fortune has surfaced — it is a powerful editorial framing but exactly the kind of pundit-derived ratio Mungomash avoids hard-typing into prose. The November 2023 OpenAI-board-episode lineage (relevant to the broader AI-lab competitive frame but not to Anthropic's own financials). Compensation specifics. Investor-deck leaks asserted as fact. Speculation about post-IPO governance changes to the LTBT.

Refresh cadence. Hand-curated values are re-verified weekly against the load-bearing primary sources (anthropic.com/news, claude.com/customers, the EDGAR full-text search for "Anthropic" / "Anthropic PBC", Amazon's 10-Q Anthropic footnote plus a check that Alphabet's aggregate investment disclosures still leave the stake unnamed, and the most-recent CNBC / Bloomberg / Reuters / NYT / WSJ / Fortune / The Information coverage). The weekly cadence matches the site-wide financials-pages convention and is appropriate to a fast-moving private company at the peak of an IPO process.

Cross-references. Anthropic Leadership for founders, LTBT mechanics, senior team, and the funding timeline as governance events. Anthropic Lawsuits for the Bartz $1.5B settlement and the active docket. Claude Versions for the product / model release history. Anthropic's row on /orgs/ for the company profile.
