Anthropic: valuation, revenue and the road to an IPO

By Unicorn Private Research. Published and last updated 26 September 2026.

Key takeaways

Anthropic's last primary round valued the company at 965 billion dollars post-money, announced on 28 May 2026.
The company confirmed it submitted a confidential draft registration statement on Form S-1 to the SEC on 1 June 2026.
Reuters has been reported as saying the company could raise up to 100 billion dollars at a valuation approaching 2 trillion dollars. That is a press report about a possible price, not a price.
Run-rate revenue crossed 47 billion dollars in May 2026, against 14 billion dollars reported three months earlier.

Anthropic is the most highly valued private company in this tracker, at 965 billion dollars post-money as of its Series H announcement on 28 May 2026, and it is the closest of the large private artificial intelligence companies to a public listing. It confirmed a confidential S-1 filing with the United States Securities and Exchange Commission on 1 June 2026. Everything published since about the size of the listing is a press report, and this page separates the two.

The reported valuations, and who reported them

Three numbers circulate for Anthropic and they mean different things. The first two are company-confirmed primary round prices. The third is press reporting about a listing that has not priced.

Figure	What it is	Source and date
380 billion dollars	Series G post-money valuation	Anthropic, 12 February 2026
965 billion dollars	Series H post-money valuation	Anthropic, 28 May 2026
Approaching 2 trillion dollars	Reported possible IPO valuation, with up to 100 billion dollars raised	Reuters, reported by Forbes, 17 September 2026

The gap between the second and third figure is the whole question for anyone buying before the listing. A 965 billion dollar entry price and a 2 trillion dollar listing price are a very different proposition from a 965 billion dollar entry and a listing at or below the last round.

The revenue behind the valuation

The valuation has moved because the revenue has moved, and the disclosed figures are unusually specific for a private company.

February 2026: run-rate revenue of 14 billion dollars, with the company stating growth of roughly ten times a year in each of the prior three years.
May 2026: run-rate revenue crossed 47 billion dollars, stated in the Series H announcement.
End of July 2026: annualised revenue reported at more than 65 billion dollars, against about 9 billion dollars at the end of 2025.
Company projections reported by Forbes: roughly 120 billion dollars by the end of 2026 and roughly 200 billion dollars for 2028.

The first two figures come from Anthropic itself. The third and fourth are press reporting of company projections, and projections are the least reliable category on this page.

The road to a listing

A confidential S-1 is a draft registration statement filed with the SEC that is not published while the regulator reviews it, so the financial detail that would let an outside investor test the valuation is not yet available.

1 June 2026: Anthropic confirms it submitted a draft registration statement on Form S-1.
The SEC review runs in private. The prospectus becomes public only when the company decides to proceed and files publicly.
Investor meetings were reported for the fourth quarter of 2026. A roadshow normally precedes pricing by a matter of weeks.
Pricing sets the only valuation that is not an estimate. Everything before it, including the 965 billion dollars, is a negotiated private price or a report.

What a buyer is taking on before the listing

Forbes set out the specific risks for someone entering at this stage on 17 September 2026, and they are worth reading against any offer to buy shares now.

Entry price. A buyer today enters at the highest valuation in the company's history, after rounds at 380 and 965 billion dollars.
Where the capital goes. Much of the money raised may flow back to strategic partners that are also suppliers, notably Amazon, Google and Nvidia, one of which has been reported as considering an anchor investment of up to 10 billion dollars.
Governance. Anthropic's Long-Term Benefit Trust structure is designed to weigh safety considerations, which may not align with maximising shareholder return.
Information. Until the prospectus is public, no outside buyer can see audited accounts, the capital structure or the preference stack.
Structure. A secondary purchase before a listing may be common stock sitting behind several layers of preferred shares, and may be held through a vehicle rather than directly.

Exposure before a listing

There is no way for a retail investor to buy Anthropic shares directly. Exposure before a listing is obtained through the private secondary market, where existing shareholders, usually employees or early funds, sell to qualified investors, and where the transaction is subject to the company's approval. Unicorn Private operates in exactly this segment: it acquires secondary stakes in established private technology companies already valued above one billion dollars and holds them to an exit. That is a different activity from venture capital, which funds companies at a stage where most fail, and it carries its own risks, principally the entry price, the absence of a guaranteed exit and the time to one.

The short answer

Anthropic was valued at 965 billion dollars by its own last funding round in May 2026, has filed confidentially for an IPO, and is the subject of press reports pointing to a listing valuation approaching 2 trillion dollars. The first figure is documented, the second is confirmed by the company, and the third is a report about a price that does not yet exist. Any decision taken before the prospectus is public is taken without the financial detail that decision would normally require.
