Anthropic IPO Valuation: Aswath Damodaran Values the Claude Maker at $1.475 Trillion, Just Below the Reported $1.5 to $2 Trillion IPO Range, With Scenarios From Negative $373 Billion to $4.04 Trillion

The Anthropic IPO valuation debate has its first heavyweight voice: Aswath Damodaran, the New York University finance professor known as the Dean of Valuation, published a full valuation on 28 October 2026 that puts Anthropic's equity at about $1.475 trillion. That is just under the $1.5 trillion to $2 trillion range that has been reported for the Anthropic IPO, and it comes two days after the Claude maker filed its S-1 filing with the US Securities and Exchange Commission.

This article explains what Aswath Damodaran's Anthropic IPO valuation assumes, how his worst and best cases of negative $373 billion and $4.04 trillion are built, what the S-1 shows on revenue and losses, why he is wary of the share structure, and what the Anthropic IPO valuation means for investors who may follow the listing from India. Every figure below comes from Aswath Damodaran's post, Anthropic's filing or reporting on them.

Anthropic IPO Valuation at a Glance: Aswath Damodaran's Numbers

Aswath Damodaran's Anthropic IPO valuation of $1.475 trillion is his base case, which he describes as an upbeat story, and it sits at the lower end of the offer pricing range of $1.5 trillion to $2 trillion that he cites. The company has not yet set a price or share count for the Class A shares, so that range is a reported expectation rather than an announced figure.

How Aswath Damodaran Values Anthropic: The Story Behind the Number

Aswath Aswath Aswath Damodaran's method is to attach a story to each number, and the story behind his Anthropic IPO valuation is that artificial intelligence agents will expand into new markets, including drug research and testing, taking a share of the revenue those markets generate. With that story he believes it is plausible that Anthropic's revenue could approach a trillion dollars in a decade, with a target operating margin of 27.5%, reinvestment that delivers three dollars of revenue for every dollar of capital invested, and a cost of capital he sets in his model.

That is why the Anthropic IPO valuation from Aswath Damodaran should be read as a story with numbers attached, not a forecast of the share price. He adds a second argument for the upbeat case: as a trillion-dollar public company, Anthropic would have access to capital. He also treats the company's large compute commitments as debt-like obligations in his inputs, which lowers the equity value and shows how compute costs drive the Anthropic IPO valuation, and he applies a regulatory drag to margins in the base case.

The Worst Case: Negative $373 Billion

In the worst Anthropic IPO valuation scenario the company does not survive as a going concern, and the model produces a negative equity value of $373 billion, which in practice means the shares would be worth nothing. The uncertainty he highlights spans revenue, margins, compute costs, competition and regulatory pressure.

The Best Case: $4.04 Trillion

In the best Anthropic IPO valuation scenario revenue reaches $1.5 trillion in 2036, margins converge on those of premium markets at 40%, computing becomes cheaper so that each dollar of capital supports four dollars of sales, the cost of capital falls to 7.79%, and regulation has no effect on margins. Those assumptions together give an equity value of $4.04 trillion, nearly three times his base case.

What Anthropic's S-1 Filing Shows: Revenue, Losses and Compute Costs

The Anthropic IPO valuation rests on Anthropic's S-1 filing, made public on 26 October 2026, is for Class A shares to be listed on the Nasdaq Global Select Market under the ticker ANT, with the share count, price range and listing date left blank. Anthropic had filed a confidential draft on 1 June 2026. Reports point to a November Nasdaq listing, but no date is confirmed.

Metric from the filing	Figure
Revenue, first half of 2026	About $16.29 billion
Revenue, first half of 2025	About $1.16 billion
Revenue, full year 2025	About $4.59 billion
Q1 2026 revenue	About $4.7 billion
Q2 2026 revenue	About $11.6 billion (about 145% above Q1, our calculation)
Q3 2026 revenue	$16.8 billion, shared with investors on 14 October, about 45% above Q2
Net loss, first half of 2026	About $80.7 billion
Share of the loss that is non-cash	Roughly $72 billion, from the rising value of convertible notes
Compute commitments	More than $600 billion, per Benzinga's reading of the filing

Source: Anthropic's S-1 as reported by Reuters, Benzinga, Stocktitan and Techloy. The third-quarter figure is not in the filing; it was given to investors on 14 October.

The headline net loss of $80.7 billion looks alarming in any Anthropic IPO valuation against $16.3 billion of revenue, but about $72 billion of it is a non-cash charge created when convertible notes held by investors rose in value along with the company. Aswath Damodaran's Anthropic IPO valuation does not depend on the one-off accounting gain, only on how fast the business grows. Strip that out and the operating picture, judged on run-rate revenue and reported revenue, is of a business whose revenue grew about 14 times year on year in the half, though Aswath Damodaran points to heavy compute costs and high operating leverage as the main risks, since compute costs are the largest fixed commitment in the model.

Is the Anthropic IPO Valuation Cheap or Expensive? The Multiples

At the $1.475 trillion Anthropic IPO valuation from Aswath Damodaran, Anthropic would trade at about 32 times its second-quarter revenue annualised, or about 22 times its third-quarter revenue annualised, using the $11.6 billion and $16.8 billion quarterly figures. Both are our calculations on quarterly figures, not the company's run-rate revenue, and the run-rate revenue figure in the prospectus itself, which is measured as of 31 October 2026, is left blank. If revenue growth keeps slowing from the roughly 145% sequential gain in Q2 to the 45% gain in Q3, the multiple on a growing base falls, but only if growth does not decelerate sharply.

Aswath Damodaran flags the same slowdown, and it is the central tension in the Anthropic IPO valuation, and it is why the Anthropic IPO valuation range is so wide. Quarterly growth fell from about 145% to 45% in one quarter, and any further fall changes how much the market will pay for each dollar of revenue. The Anthropic IPO valuation base case from Aswath Damodaran already requires revenue to grow from an annualised figure near $67 billion based on Q3 to close to $1 trillion by 2036, which is roughly 15 times in 10 years.

Why Aswath Damodaran Is Wary of the Share Structure

Aswath Damodaran has criticised the governance behind the Anthropic IPO, according to BigGo Finance's account of his comments. Anthropic's five-class share structure gives the co-founders 50.1% of the voting power and lets the Long-Term Benefit Trust elect a majority of the board, so holders of Class A shares, the Class A shares being offered to the public, do not control the board. Aswath Damodaran said the structure would make him demand a deeper discount before buying a single share.

Aswath Damodaran also said his Anthropic IPO valuation will leave him on the sidelines at the IPO if the price is well above $1.48 trillion, since the rumoured pricing is $1.5 trillion to $2 trillion, but he added that this is a story with twists and turns, and that as value and price both change over time he is convinced it will become a buy at some point. Invezz notes that he cautions against shorting the stock as well.

What Other Analysts Say About the Anthropic IPO

Not every voice on the Anthropic IPO valuation is cautious. Against the Anthropic IPO valuation from Aswath Damodaran, Dan Ives of Yorkville Ives has said he expects strong appetite if the deal prices near $1.5 trillion, though he would not be an assertive buyer at $2 trillion and would decide on entering after the IPO depending on the final price. The gap between that view and Damodaran's shows how wide the range of the Anthropic IPO valuation is before a price is set. India IPO's report notes there is no comparable listed company for the Anthropic IPO valuation, so the IPO will become the benchmark that others are measured against.

What Indian Investors Should Know About the Anthropic IPO

The Anthropic IPO will be on the Nasdaq, not on an Indian exchange, so Indian residents who want exposure would need to use a platform that offers US stocks and follow the RBI's Liberalised Remittance Scheme rules and the applicable tax treatment, which they should check for the current limits. Consult a SEBI-registered financial advisor and a tax adviser before investing in an overseas IPO, and note that the IPO price, share count and date are still unknown.

Conclusion

The Anthropic IPO valuation of $1.475 trillion from Aswath Damodaran is not a prediction of where the shares will trade; it is his estimate of what the equity is worth if Anthropic's revenue approaches a trillion dollars by 2036 at a 27.5% margin. The S-1 filing shows revenue growing about 14 times year on year to $16.3 billion in six months, a $80.7 billion loss that is mostly non-cash, and compute commitments above $600 billion. Until Anthropic sets a price and the Anthropic IPO valuation meets reality, the practical question for investors is how far above $1.5 trillion they would be willing to pay, and Aswath Damodaran's answer to the Anthropic IPO valuation question is that he would wait.

Frequently Asked Questions on Anthropic IPO Valuation

What is Aswath Damodaran's Anthropic IPO valuation?

Ans. Aswath Damodaran, the NYU Stern professor known as the Dean of Valuation, values Anthropic's equity at about $1.475 trillion in a post published on 28 October 2026. That is just below the $1.5 trillion to $2 trillion IPO pricing range reported for the offering. His scenarios range from negative $373 billion in the worst case, where the company does not survive as a going concern, to $4.04 trillion in the best case.

When did Anthropic file for its IPO and what is the ticker?

Ans. Anthropic publicly filed its S-1 with the US Securities and Exchange Commission on 26 October 2026, after a confidential draft on 1 June 2026. The company plans to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT. The filing left the number of shares, the price range and the listing date blank, and reports point to a November listing that has not been confirmed.

What revenue and loss did Anthropic report in its S-1?

Ans. Anthropic reported revenue of about $16.29 billion in the first half of 2026, up from about $1.16 billion in the same period of 2025 and compared with about $4.59 billion for all of 2025. Second-quarter revenue was about $11.6 billion. The company reported a net loss of about $80.7 billion for the half, of which roughly $72 billion is a non-cash charge caused by the rising value of convertible notes. It told investors that third-quarter revenue was $16.8 billion.

Will Aswath Damodaran buy Anthropic shares at the IPO?

Ans. Aswath Damodaran has said his $1.475 trillion valuation will leave him on the sidelines at the IPO if the price is well above his estimate, since the rumoured pricing range is $1.5 trillion to $2 trillion. He also said he is convinced Anthropic will become a buy at some point as value and price change over time, and he has cautioned against shorting the stock. He added that his decision on buying or selling will be informed by his Anthropic IPO valuation but that investors should value the company themselves.

How is the $4.04 trillion best case for Anthropic calculated?

Ans. In Damodaran's best case, Anthropic's revenue reaches $1.5 trillion in 2036, operating margins converge on the premium market level of 40%, computing becomes cheaper so that each dollar of capital supports four dollars of sales, the cost of capital falls to 7.79%, and regulation has no effect on margins. These assumptions together give an equity value of $4.04 trillion, nearly three times his base case of $1.475 trillion.

Why did Anthropic report an $80.7 billion loss?

Ans. Anthropic's net loss of about $80.7 billion in the first half of 2026 is mostly a non-cash accounting charge. Roughly $72 billion of it arose because convertible notes sold to investors rose in value as the company's valuation rose, and under accounting rules that increase is booked as a loss. The remainder reflects operating costs, including heavy spending on computing infrastructure, which was about $9 billion in the first six months of 2026.

What is Damodaran's concern about Anthropic's share structure?

Ans. According to BigGo Finance's account, Aswath Damodaran criticised Anthropic's five-class share structure, which gives the co-founders 50.1% of the voting power and the Long-Term Benefit Trust the right to elect a majority of the board. Holders of Class A shares, the stock being offered in the IPO, would not control the board. He said this governance setup would make him demand a far deeper discount before buying a single share.

Can Indian investors buy Anthropic shares in the IPO?

Ans. The Anthropic IPO will be on the Nasdaq, not an Indian exchange, so Indian residents would need a platform that offers US stocks and would have to follow the RBI's Liberalised Remittance Scheme rules and the applicable tax treatment, whose current limits should be checked. The IPO price, share count and date have not been announced. This is not investment advice, so consult a SEBI-registered financial advisor and a tax adviser before investing in an overseas listing.
