Valuation expert Aswath Damodaran has trimmed his estimate of Anthropic’s equity value to $1.45 trillion, slightly down from his previous estimate of $1.475 trillion, after updating his model with the company’s third-quarter figures.
The New York University finance professor, widely known as the “Dean of Valuation”, published the revised estimate in a Substack post on November 3, in which he stress-tested his own Anthropic valuation and ranked the assumptions driving it by how much they matter and how uncertain they are.
The small size of the revision is itself part of the story. Damodaran wrote that replacing third-quarter 2025 revenue with third-quarter 2026 revenue raised his base revenue figure, but he kept his estimate for revenue over the coming 12 months at about $100 billion, so first-year growth was adjusted down to deliver that result. He added that slower third-quarter revenue growth had been, in his words, an open secret he had already built into his story.
Why the $1 trillion revenue target matters most
“If I were forced to pick one variable around which my valuation revolves the most, it is my estimate of the target revenues for Anthropic, which I estimate to reach a trillion dollars in ten years,” Damodaran wrote.
That figure is his own assumption, not a company forecast. Anthropic has not said it expects $1 trillion in annual revenue by 2036. Damodaran’s point is that the whole valuation leans on it: if revenue falls short, margins would compress, contracted compute capacity could sit idle, and the risk of failure would rise — with each miss reinforcing the others.
His model assumes a target operating margin of 27.5% after a regulatory-risk haircut (32.5% before it), a 9.74% cost of capital, and $3 in additional revenue for each $1 reinvested. It also treats Anthropic’s contractual compute commitments as debt-like obligations, with an aggregate value of just over $450 billion and a present value of about $373 billion. He put the probability of failure in his model at 10%.
Still below the $2 trillion talk — but above the sceptics
Damodaran’s $1.45 trillion sits below the $2 trillion figures discussed for Anthropic earlier in the IPO process, and below the $1.5 trillion to $1.6 trillion range that the Wall Street Journal reported some institutional investors had advised for the offering. It is, however, well above the roughly $1 trillion figure that respondents to his own online valuation exercise generally produced, and far above the $583 billion alternative estimate published by one independent analyst using different operating assumptions.
The range shows how much the answer depends on the story, not just the spreadsheet. In Damodaran’s own scenarios, a pessimistic case — $200 billion of revenue by 2036 and a 10% operating margin — produces a negative equity value, while an optimistic case — $1.5 trillion of revenue and a 40% margin — reaches $4.04 trillion. The wide spread is the point: for a company at this stage, the valuation is a bet on a decade of execution, not a measurement of today’s business.
What the third-quarter filing actually showed
Anthropic’s amended prospectus, filed on November 2, reported $16.956 billion in revenue and a $567 million operating loss for the three months ended September 30, with compute and infrastructure expenses of $9.863 billion. The quarterly figures are unaudited, and the filing leaves the offering’s share count and price range blank, with a planned Nasdaq listing under the ticker ANT.
Damodaran also flagged governance as his second-ranked concern, calling the combination of Anthropic’s public benefit corporation structure and founder-controlled voting shares a red flag, and warning that concentrated founder control could slow the company’s response if its strategy needs to change.
What to watch next
The next hard data points are the IPO’s pricing and share count, any further prospectus amendment, and whether Anthropic’s revenue growth re-accelerates or continues to slow. Until then, Damodaran’s revision is best read as a warning about fragility rather than a verdict: a $25 billion trim on a $1.475 trillion estimate is small, but the assumption it exposes — $1 trillion of revenue within a decade — is, by his own ranking, the one on which everything else depends.
Frequently asked questions
Is $1.45 trillion Anthropic’s IPO valuation? No. It is Damodaran’s independent estimate of the company’s equity value under his stated assumptions. Anthropic has not announced a final IPO price or valuation.
Why did the estimate fall only slightly? Because Damodaran kept his coming-12-months revenue estimate at about $100 billion and had already allowed for slowing third-quarter growth; the update mainly changed the base year in his model.
What would change the valuation most? The $1 trillion-by-2036 revenue assumption. Damodaran ranks it first for both magnitude and fragility, ahead of governance, profitability, investment needs and regulatory risk.
