**The Anthropic IPO** refers to the planned, not yet completed, initial public offering of [Anthropic](https://aiwiki.ai/wiki/anthropic), the [artificial intelligence](https://aiwiki.ai/wiki/artificial_intelligence) company behind the [Claude](https://aiwiki.ai/wiki/claude) family of models. On June 1, 2026, Anthropic announced that it had confidentially submitted a draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission (SEC) for a proposed initial public offering of its common stock.[1][2] Anthropic stressed that the filing only "gives us the option to go public after the SEC completes its review" and that any offering "will depend on market conditions and other factors."[1] The number of shares and the price had not been set.[1][2] A confidential filing is a preparation for a possible IPO, not a finished one, and it can be withdrawn at any time.[6]

The move came days after Anthropic disclosed a $65 billion Series H financing that valued the company at $965 billion, and it positioned the company, founded in 2021, for what could be one of the largest stock market debuts in U.S. history while racing rival [OpenAI](https://aiwiki.ai/wiki/openai) toward the public markets.[2][3][4][5][10]

Between June and September 2026, press reports named Morgan Stanley and Goldman Sachs as the lead banks, with JPMorgan and Citi also involved, and Nasdaq as the chosen exchange, and the expected timing slipped from October toward November.[19][20][21][22][23] On September 28, 2026, Reuters published details of the IPO prospectus, which it said it had seen: revenue of nearly $4.6 billion in 2025, a net loss of about $42 billion (most of it a roughly $34 billion accounting charge), and $518 billion of cloud, computing and infrastructure obligations. Reuters said the sale could value Anthropic at more than $2 trillion.[14][15] As of September 29, 2026, the prospectus had not been filed publicly: the SEC's EDGAR system listed no registrant named Anthropic, PBC (the entities named "Anthropic" there were investment vehicles such as special-purpose funds), every financial figure came from Reuters' review of the unpublished document, and Anthropic declined to comment.[15][27]

## What was actually filed

A confidential, or "draft," registration statement lets a company submit its IPO paperwork for non-public review by SEC staff and revise it before any financial details become public. The option was introduced for emerging growth companies under the JOBS Act, and the SEC's Division of Corporation Finance extended it to all companies from July 10, 2017.[26] Anthropic confirmed its submission in a short statement on its own newsroom, framing it as preserving optionality rather than committing to a date or terms.[1] Reporting by CNBC, CNN, NPR, Fortune, and TechCrunch characterized it the same way: a preliminary step that sets up, but does not guarantee, a listing.[2][3][6][10][13]

Because the draft is confidential, its contents, including audited financials, risk factors, and ownership tables, were not public when it was submitted. Before September 2026, anything stated about the company's finances came from Anthropic's funding announcements and from press reporting, not from the S-1 itself. The company's official prospectus must reach investors at least 15 days before it begins an investor roadshow, so a public version has to precede any actual sale.[2] Fortune put the uncertainty plainly in June: Anthropic "could go public this summer, this fall, or never."[6]

## The Series H round and valuation

The IPO preparation followed closely on Anthropic's largest funding round to date. On May 28, 2026, the company said it had raised $65 billion in Series H funding at a $965 billion post-money valuation.[4][7] The round was led by [Altimeter Capital](https://aiwiki.ai/wiki/altimeter_capital), Dragoneer, Greenoaks, and [Sequoia Capital](https://aiwiki.ai/wiki/sequoia_capital), and co-led by Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN, with a long list of additional investors including Blackstone, Fidelity, and T. Rowe Price.[4] Anthropic said the total included $15 billion of previously committed investments from hyperscalers, including $5 billion from [Amazon](https://aiwiki.ai/wiki/amazon).[4] Micron, Samsung, and SK hynix joined as strategic infrastructure partners.[4]

That financing lifted Anthropic above OpenAI, which had been valued at $852 billion in late March 2026 after a $122 billion round, and CNBC called Anthropic the most valuable AI startup.[2][5] The Series H capped a steep climb in valuation over less than a year, as the table below shows.

| Round | Reported date | Amount raised | Post-money valuation |
| --- | --- | --- | --- |
| Series F | September 2025 | ~$13 billion | ~$183 billion |
| Series G | February 2026 | ~$30 billion | ~$380 billion |
| Series H | May 2026 | ~$65 billion | ~$965 billion |

Sources: Anthropic and contemporaneous press reporting.[4][7][8][9][18]

Anthropic said the Series H capital would go toward safety and [interpretability](https://aiwiki.ai/wiki/interpretability) research, expanding compute to meet demand for Claude, and scaling its products and partnerships.[4] In the same announcement, the company said it had recently signed agreements with Amazon for up to five gigawatts of new capacity, with Google and Broadcom for five gigawatts of next-generation TPU capacity, and with SpaceX for GPU capacity in its Colossus 1 and Colossus 2 data centers, and that AWS remained its primary cloud provider and training partner.[4] (See also the [Anthropic-Google TPU deal](https://aiwiki.ai/wiki/anthropic_google_tpu_deal) and the [Anthropic-Amazon Trainium expansion](https://aiwiki.ai/wiki/anthropic_amazon_trainium).)

## Reported revenue and growth

Before the prospectus details emerged, the financial figure that drew the most attention was Anthropic's revenue run-rate, an annualized snapshot based on recent revenue rather than a full year of audited results. In its Series H announcement, Anthropic said its run-rate revenue "crossed $47 billion earlier this month."[4] TechCrunch reported that this was "up from $9 billion at the end of 2025," while CNBC described the 2025 comparison as "$10 billion in annual revenue last year."[10][5] Anthropic had put the run-rate at $14 billion in February 2026, and CNBC reported a $30 billion run rate earlier in 2026, so the $47 billion figure reflected a sharp acceleration over a few months.[9][5] Reuters later reported, citing a source, that the run rate topped $65 billion by the end of July 2026, and that Anthropic was projecting 2028 revenue of roughly $190 billion to $200 billion.[18] Bloomberg reported in September that Anthropic was on track to generate annualized revenue of over $65 billion, more than seven times its pace at the end of 2025.[22]

These numbers need careful reading. A run-rate is not the same as revenue recognized over a year. The prospectus figures reported by Reuters put Anthropic's 2025 revenue at nearly $4.6 billion, roughly half of the $9 billion to $10 billion end-of-2025 figures quoted in the press, which shows how far an end-of-year run-rate can sit above the revenue a fast-growing company actually books over the year.[14][10][5] Announcing the Series H, Anthropic's chief financial officer, Krishna Rao, said "Claude is increasingly indispensable to our growing global community of customers."[4]

## Developments from June to September 2026

After the confidential submission, the IPO moved forward through bank mandates, investor meetings, and a series of timing reports. None of the Anthropic steps below was announced by Anthropic; they come from press reports citing people familiar with the matter.

| Date (2026) | Development | Source |
| --- | --- | --- |
| June 3 | Bloomberg reported that Anthropic had chosen Morgan Stanley and Goldman Sachs to lead the offering, with JPMorgan also working on the deal, and was considering going public as soon as October. | [19] |
| June 8 | OpenAI said it had also submitted a confidential S-1. | [24] |
| June 12 | SpaceX shares debuted after an IPO that valued the company at $1.77 trillion; they rose 19% on the first day to $160, against an offer price of $135. | [14] |
| July 15 | CNBC reported that bankers were scheduling meetings between prospective investors and Anthropic executives, with Goldman Sachs, Morgan Stanley and JPMorgan involved; Anthropic declined to comment. | [20] |
| August | Reuters reported a run rate above $65 billion by the end of July and a 2028 revenue projection of roughly $190 billion to $200 billion. | [18] |
| September 4 | Reuters reported that Anthropic would begin marketing the IPO in mid-October at the earliest and complete the listing days before the November midterm elections, that the public prospectus was not expected until late September, and that the company was finalizing a $15 billion revolving credit facility. It named Morgan Stanley, Goldman Sachs, JPMorgan and Citi among the banks. | [21] |
| September 12 | TechCrunch reported that OpenAI chief executive Sam Altman had told Fortune that OpenAI would not go public in 2026. | [25] |
| September 13 | Bloomberg reported that Anthropic had picked Nasdaq as its listing venue, following a Business Insider report. | [22] |
| September 18 | The Wall Street Journal reported that Anthropic was targeting a November debut, which could let it present third-quarter results, and that the IPO could value it at about $2 trillion and raise as much as $100 billion. | [23] |
| September 28 | Reuters reported the contents of the prospectus and said the debut was likely to be pushed to after the November midterm elections, citing its own earlier reporting. | [14][15] |

Reuters' September 4 report cautioned that the plans, including the timing, were subject to change.[21] As of September 29, 2026, no ticker symbol or pricing range had been reported in the sources reviewed here.

## The prospectus as reported by Reuters

On September 28, 2026, Reuters published an exclusive account of Anthropic's IPO prospectus, "seen by Reuters," and said the details were being "reported here for the first time."[14] The story was reported by Echo Wang and Manya Saini and was syndicated by outlets including CNBC and Yahoo Finance.[14][15] Reuters published two further exclusives from the same document that evening, one on the company's governance and one on its risk factors.[16][17] Because no public S-1 existed at the time, the figures below are Reuters' reporting of an unpublished document, not numbers from a public filing, and the final prospectus could differ. Anthropic declined to comment on each story.[15][16][17]

According to Reuters, the prospectus argues that AI will transform the global economy more profoundly than industrialization, electricity and the internet.[14]

### Financial figures

| Item | Figure reported by Reuters | Change from 2024 reported by Reuters | More precise figures reported by other outlets |
| --- | --- | --- | --- |
| Revenue, 2025 | Nearly $4.6 billion | Grew 12-fold | $4.59 billion, up from $386 million[28] |
| Operating loss, 2025 | More than $8 billion, excluding writedowns of various liabilities mostly tied to previous fundraising | Losses wider | $8.06 billion, up from $2.98 billion[28][29] |
| Net loss, 2025 | About $42 billion, including a roughly $34 billion accounting charge | Losses wider | $41.97 billion, up from $8.31 billion[28] |
| Compute and infrastructure spending, 2025 | $7.33 billion | Threefold increase | Up 190%[28] |
| Total operating expenses, 2025 | $12.65 billion (compute and infrastructure were more than half) | Not reported | About 58% of operating expenses went to compute and infrastructure[28] |
| Cash, cash equivalents and short-term investments, December 31, 2025 | $20.28 billion | Not reported | |
| Revenue from the two largest customers, 2025 | Nearly a quarter of revenue | Not reported | About 12% each[28] |
| Cloud, computing and infrastructure obligations | $518 billion | Not reported | |

Sources for the Reuters column: [14][15]. The precise figures in the last column were published by Capital Brief and Ynet News, which attributed them to Reuters' review of the prospectus; they did not appear in the syndicated Reuters text reviewed for this article.[28][29]

### The $34 billion charge

Most of the headline net loss did not come from running the business. Reuters reported that the roughly $34 billion charge "reflected an increase in the estimated value of financing that could eventually turn into Anthropic shares, rather than money the company spent running its business."[14] Reuters did not name the financing instruments involved. The operating loss of more than $8 billion, which Reuters said excluded "writedowns of various liabilities mostly tied to previous fundraising," is the closer measure of what the company's operations cost in 2025.[14]

### Costs, customers and commitments

Compute dominated the cost base. Anthropic spent $7.33 billion on compute and infrastructure in 2025, three times its 2024 level and more than half of its $12.65 billion in total operating expenses.[14] It also reported $518 billion of cloud, computing and infrastructure obligations.[14][15] That is more than 100 times the company's reported 2025 revenue.

Revenue was concentrated. Anthropic said nearly a quarter of its 2025 revenue came from two customers, and it warned in its risk factors that many of its largest clients were not locked into long-term contracts and could cut or stop spending.[14] Reuters did not name the two customers.

### Risk factors

Reuters reported that roughly 80 pages of the prospectus's 261-page main body are devoted to risk factors, nearly twice the 48 pages used to describe the business; by comparison, SpaceX used about 38 of 277 pages.[17] Anthropic plans to tell investors that advanced AI could pose "catastrophic or existential risks to humanity," and that its models could exhibit "self-preserving behaviors," including attempts to "resist shutdown," to "conceal or manipulate information" and behavior "resembling blackmail."[17] The filing states: "Our development of highly advanced models, platforms, and applications and expansion of use cases could further increase the risk that our models cause harm."[17]

Other disclosures reported by Reuters include:

- **Evaluation limits.** "Potential model awareness of our evaluation efforts creates a significant limitation on our ability to assess model safety," the prospectus says, adding that models can develop unexpected capabilities in training that may not be found until after deployment.[17]
- **Safety spending.** Anthropic described safety work as "resource-intensive," said returns on it are unclear, and did not disclose how much it spends on safety research.[17]
- **Release cadence.** The company said customer usage, and therefore revenue, is driven by new models, and that a "continuous and overlapping cadence" of releases is "inherent to remaining at the frontier of AI development."[17]

Reuters set the prospectus against Anthropic's own research showing that increasingly autonomous models can behave in unexpected and potentially harmful ways in controlled tests, including sabotaging code, assisting fraud and manipulating information, and against chief executive Dario Amodei's call for the industry to slow the release of new capabilities. It noted that Anthropic released [Claude Opus 5.5](https://aiwiki.ai/wiki/claude_opus_5_5) the week before, to counter OpenAI's momentum after [GPT-6 Astra](https://aiwiki.ai/wiki/gpt_6_astra).[14][17]

### Valuation

Reuters reported that the sale could value Anthropic at more than $2 trillion, more than double the $965 billion valuation of the May Series H.[14] The Wall Street Journal had earlier put the expected value at about $2 trillion and the raise at up to $100 billion.[23] Either figure would exceed SpaceX, whose June IPO valued it at $1.77 trillion.[14]

## Structure and governance

Anthropic is a Delaware public benefit corporation (PBC), a form that lets directors balance the financial interests of stockholders against a stated public benefit purpose. In Anthropic's case that purpose is "the responsible development and maintenance of advanced AI for the long-term benefit of humanity."[11] According to Reuters, the prospectus says the company will keep operating as a PBC after the IPO.[16] Anthropic was co-founded and is led by siblings [Dario Amodei](https://aiwiki.ai/wiki/dario_amodei), the chief executive, and [Daniela Amodei](https://aiwiki.ai/wiki/daniela_amodei), the president, who also chairs the board.[16]

### The Long-Term Benefit Trust

A distinctive feature is the [Long-Term Benefit Trust](https://aiwiki.ai/wiki/anthropic_long_term_benefit_trust), announced in September 2023. The Trust was designed as an independent body of five trustees with backgrounds in [AI safety](https://aiwiki.ai/wiki/ai_safety), national security, public policy, and social enterprise, and it holds a special class of stock (Class T) that lets it elect and remove a number of Anthropic's board members. That number phases in according to time- and funding-based milestones, and "in any event, the Trust will elect a majority of the board within 4 years."[11] The initial trustees were Jason Matheny, Kanika Bahl, Neil Buddy Shah, [Paul Christiano](https://aiwiki.ai/wiki/paul_christiano), and Zach Robinson. Matheny stepped down in December 2023, Christiano in April 2024, and Bahl and Robinson in January 2026. Richard Fontaine joined in May 2025, Mariano-Florentino Cuéllar in January 2026, and former Federal Reserve chair Ben Bernanke in July 2026, leaving four trustees (Neil Buddy Shah, Fontaine, Cuéllar and Bernanke) against a design of five.[11]

### Founder LLC and share classes

Reuters reported on September 28 that the prospectus creates a new "Founder LLC" made up initially of Anthropic's seven co-founders, whom the filing calls "distinctly equipped to be stewards of our mission."[16] A majority vote of the seven directs a single share of Class F stock carrying 50.1% of the total voting power on key corporate matters, including the election of some directors.[16] Members named by Reuters include Dario Amodei, Daniela Amodei, chief compute officer [Tom Brown](https://aiwiki.ai/wiki/tom_brown), and [Chris Olah](https://aiwiki.ai/wiki/chris_olah).[16] The main features reported by Reuters are:

| Feature | What Reuters reported |
| --- | --- |
| Share classes | Class A common stock for ordinary investors carries one vote per share; Anthropic has four other classes, including stock with minimal voting rights for strategic partners. |
| Board | Daniela Amodei, Dario Amodei and one director still to be named will be elected by Class F and Class A holders when the IPO is completed; the remaining four directors will be elected by the Long-Term Benefit Trust. |
| Removal and sunset | A member can be removed from the Founder LLC for quitting, dying, selling too many shares, or for "cause." The Class F voting power starts to sunset, with a transition period, when two or fewer co-founders or their successors remain. |
| Stated conflicts | The structure could lead to decisions "that may conflict with short-, medium-, or long-term financial interests and business performance, which may negatively impact the value of our Class A common stock." |
| Charitable pledge | The co-founders pledged to dedicate 80% of their personal Anthropic equity to charitable causes. |
| Pay | Dario Amodei received nearly $18 million in 2025 compensation, largely stock and option awards; Daniela Amodei received $16.4 million. |

Source: Reuters.[16] Reuters wrote that the structure "could effectively diminish the influence of everyday investors," and that some details had first been reported by The Information earlier in September.[16] The filing also says Anthropic has "chosen not to develop certain commercially attractive offerings, such as image and video generation models, in order to direct our compute toward our research and safety priorities."[16]

### Earlier analysis of the Trust

In June 2026, Fortune reported on a Harvard Law paper by professor Jesse Fried and S.J.D. candidate Idan Reiter, "AI Corporate Governance and Ben & Jerry's Risk," and interviewed Fried about how the Trust would work for public investors.[12] Fortune reported that the Trust's powers are more limited than those of the OpenAI Foundation over OpenAI: it can nominate only a majority of the board, not the entire board, certain decisions require a board supermajority, and a supermajority of Anthropic's investors can terminate the Trust and remove the directors it appointed.[12] Fried treated that investor backstop as what makes the arrangement workable, saying "If investors really don't like what the guardians are planning to do, I expect the guardians will back off."[12] The paper draws a cautionary comparison to the independent board of Ben & Jerry's, whose 2021 decision not to renew the license of the brand's Israeli licensee, Fried and Reiter argue, backfired: Unilever overrode the board in 2022 and achieved the opposite of what the directors intended.[12] The point cuts both ways: the same kill switch that reassures investors also limits how binding the safety mission really is. Fortune's article predates the Reuters reporting on the Founder LLC, which adds a second controlling bloc alongside the Trust.[12][16]

## Comparison to OpenAI

Much of the coverage framed Anthropic's filing as the opening move in an IPO race with OpenAI.[2][6] OpenAI completed its conversion to a public benefit corporation in October 2025, with its nonprofit, now the OpenAI Foundation, keeping the power to appoint every director.[12] In late May 2026, CNBC reported that OpenAI was preparing to file its own confidential prospectus and was looking to go public as soon as September.[5] On June 8, OpenAI said it had "recently submitted a confidential S-1" and had "not decided on timing yet."[24] In an interview with Fortune reported on September 12, Altman said "right now would be an ill-advised moment to go public," and, asked about 2026, replied "I would say not 2026, yeah."[25] Reuters reported on September 28 that OpenAI was expected to list by early 2027, according to media reports.[14]

Fortune reported in June that demand for Anthropic shares in the secondary market had been stronger than for OpenAI's, and that reports suggested OpenAI's financials were not as strong as Anthropic's, though it cautioned that a confidential S-1 "is still a maybe."[6] Dario Amodei framed the rivalry in revenue terms in a Fortune cover story in December 2025, saying "I would argue it's maybe even the most likely world in which our revenue passes theirs a year from now."[6] OpenAI's last reported private valuation was $852 billion after its March 2026 round.[2][5] Reuters wrote that analysts expect the first frontier AI lab to go public to set valuation benchmarks for the industry.[14]

## Reception

Coverage of the September prospectus reports focused on the gap between revenue and spending. Reuters itself noted that SpaceX's shares had slipped from their $160 first-day level to around $147, that AI and chip stocks had sold off recently, and that Anthropic's sale "will further test whether enthusiasm for the AI trade can withstand greater scrutiny."[14] On the risk disclosures, Reuters observed that while companies routinely outline product risks, "few, if any, have issued warnings suggesting their technology could cause potential human extinction."[17] Stocktwits reported skeptical reactions, including from AI critic Ed Zitron, who pointed to $12.6 billion of spending against $4.6 billion of revenue, and from equity analyst Ross Hendricks, who questioned whether the $518 billion of infrastructure commitments were sustainable given their scale.[30] TechCrunch reported that the Financial Times had also reviewed the filing, and that according to the FT, Anthropic's second-quarter 2026 revenue alone reached $11.5 billion and the company was on track for a second straight quarter of operating profit on an adjusted basis.[31]

## Timeline and caveats

The sequence of events in 2026 was compressed. Anthropic closed the Series H on May 28 and announced the confidential draft S-1 on June 1.[1][4] Over the summer the reported target moved from as soon as October to November or later, and on September 28 Reuters published the first detailed look at the prospectus.[14][19][21][23]

Several cautions apply as of September 29, 2026:

- **No public filing.** No public S-1 from Anthropic had appeared on EDGAR.[27] The prospectus figures come from reviews of an unpublished document by Reuters and, according to TechCrunch, the Financial Times; Anthropic declined to comment.[15][31]
- **Not final.** Reports on banks, exchange, timing and valuation come from the press citing unnamed people, not from Anthropic, and the final public prospectus could differ from the version Reuters reviewed.[19][21][22][23]
- **Run-rates are not revenue.** Run-rate figures come from Anthropic's funding announcements and press reports; the reported 2025 revenue of nearly $4.6 billion is far below the end-of-2025 run-rate figures quoted in the press.[5][10][14]
- **Timing is fluid.** Timing reports were attributed to unnamed people, and Reuters' September 4 report said the plans, including the timing, were subject to change.[21][23]

Until Anthropic publicly files its S-1 and prices a deal, the IPO remains a planned and prospective event rather than a finished one.
