Aswath Damodaran, the NYU Stern professor who writes the Musings on Markets blog, published a post on 22 October 2026 arguing that young companies like Anthropic get priced, not valued, and on messy metrics such as the annualized revenue run rate (ARR). In his table, a $2 trillion market cap is 30.77 times the $65 billion ARR he lists for Anthropic in September 2026, and a $1.5 trillion one is 23.08 times.
He writes that the post lays out “why pricing supplants valuation in young companies” and says he will try to value Anthropic himself “when the prospectus is made public.”
Business Pill · RUN-RATE REVENUE
A short Business Engineer explainer of run-rate revenue: what an AI company’s annualized number means. It teaches the general idea only and says nothing about the figures in this piece.
The key insight: As we read it, the new element is the yardstick, not the price: Damodaran’s table shows the same $2 trillion as 30.77 times this year’s run rate and 6.67 times his 2030 revenue estimate, and he writes that the comparison depends on which one you pick.
Update, 26 Oct: Anthropic’s S-1 shows the filed numbers. Anthropic’s S-1 leaves Run-Rate Revenue as of 31 October 2026 blank, so the filing does not confirm a $65 billion figure. It does report revenue of $11,555 million for the three months ended 30 June 2026 and $16,286 million for the first half, and it leaves the IPO price range blank. More: our S-1 piece.
What Damodaran Wrote
- Why ARR. With losses and negative free cash flows, he writes, revenue is often the only viable metric for young companies: “desperation drives you up the income statement until you find a positive number.”
- Why ARR is messy. He writes that “the perils with annualized revenue rates (ARR) is that they are not standardized and can be easily gamed,” citing reports of OpenAI shifting to net revenues, which lowered its ARR from $70 billion to $50 billion, “while Anthropic continues to report gross revenues.”
- The private rounds. He lists Anthropic’s May 2026 round at $65 billion raised and a $965 billion post-money pricing, and writes that the expected IPO pricing at the time was $1.15 trillion and that “the $965 billion pricing in the VC round would have represented a $150 billion discount on the estimate.”
- The losses. His table lists operating losses in the first half of 2026 of $8.70 billion at Anthropic and $21.60 billion at OpenAI, excluding extraordinary and non-cash charges.
On what a $1.5 trillion or $2 trillion price requires, he writes: “you will have to make defensible arguments for sky-high revenue growth in the early year, a surge in operating margins to 30% or higher.”


What Was Posted on X
Rohan Paul (@rohanpaul_ai) summarised Damodaran’s blog post on X, writing that Damodaran says Anthropic’s IPO will be priced on run-rate revenue rather than valued on cash flows.
The Information wrote on X that Anthropic employees overwhelmingly believe AI will make Nobel Prize-level breakthroughs by 2030, that Wall Street is far less convinced, and that this sets up a crucial test for Dario Amodei as the company prepares to go public next month.
Rohan Paul quotes Aswath Damodaran saying the $10 trillion to $15 trillion best case for AI only happens if AI replaces people rather than serving as a tool, which Damodaran calls a terrifying story: if it comes true, he says, half of white-collar workers lose their jobs, raising the question of who buys the products. The quote is Damodaran’s as relayed in the post.
His Multiples at $1.5 Trillion and $2 Trillion
The table below reproduces rows from the pricing-multiples table in his post. The base values are his, built, he writes, from public data and leaked information.
| Metric (his base value) | Anthropic at $1.5T | Anthropic at $2T | OpenAI at $1.5T | OpenAI at $2T |
|---|---|---|---|---|
| ARR, September 2026 (Anthropic $65B; OpenAI $50B) | 23.08x | 30.77x | 30.00x | 40.00x |
| Expected ARR, end of 2026 ($110B; $70B) | 13.64x | 18.18x | 21.43x | 28.57x |
| Expected revenues, 2030 ($300B; $350B) | 5.00x | 6.67x | 4.29x | 5.71x |
| Compute contractual commitments ($414B; $600B) | 3.62x | 4.83x | 2.50x | 3.33x |
Source: Aswath Damodaran, ‘From Eyeballs to Annual Run Rates (ARR): Buzzy Pricing Metrics and the Anthropic Trade!’, Musings on Markets, 22 October 2026 (pricing-multiples table). The base values are his estimates, not company figures.
He writes that “you can make the case that Anthropic is cheaper than OpenAI, based upon the most recent ARR or the ARR in 2026, but OpenAI is cheaper relative to expected revenues in 2030, compute costs/capacity and based on user count.”
Connecting the Coverage
Our Anthropic loss piece covered The Wall Street Journal’s report, from a draft prospectus, that Anthropic recorded a net loss of $80.7 billion in the six months to 30 June 2026, $72 billion of it from accounting charges; Damodaran’s $8.70 billion figure excludes extraordinary and non-cash charges. Our Spark stake piece covered a $75 million Anthropic stake said to be worth $7 billion before the IPO.
Our earlier Damodaran piece covered his argument that AI capex is distorting earnings and cash flows. What’s new: he has put multiples on a $1.5 trillion and a $2 trillion Anthropic.
The Structural Read
As we read it, the run rate is the soft number: he writes that ARR is not standardized and that OpenAI’s shift to net revenues lowered its ARR from $70 billion to $50 billion while Anthropic reports gross.
As we read it, the private round is the anchor: his post lists May’s $965 billion post-money pricing against an expected IPO pricing of $1.15 trillion at the time.
As we read it, compute is the second yardstick: at $2 trillion, his table puts Anthropic at 4.83 times its $414 billion of compute contractual commitments.

Three Implications
FOR IPO BUYERS Damodaran writes that he will value Anthropic when the prospectus is made public, and that his intrinsic valuation will have to wait until the full prospectus gets filed.
FOR THE COMPARISON WITH OPENAI His post says Anthropic looks cheaper on the most recent ARR or 2026 ARR, while OpenAI looks cheaper on expected 2030 revenues, compute costs and capacity, and users.
FOR HOW THE NUMBER IS REPORTED He writes that Anthropic and OpenAI have both converged on monthly annualization of ARR, and that there is nothing that binds them to continue to do so.
The Business Engineer Lens
This story maps onto the Business Engineer framework The AI Capex Map & The State of AI Hyperscalers.
The framework describes its subject as “How the money flows, where it cracks, what it buys, who can absorb it”.
As we read it, Damodaran’s compute row is that question priced: his table sets Anthropic’s $414 billion of compute contractual commitments against a $1.5 trillion or $2 trillion market cap. The framework was published in May 2026 and does not discuss this post.
What Is Not Established
The base values in his tables come, he writes, from a patchwork of public data and leaked information, and are not Anthropic’s or OpenAI’s own filings. The $1.5 trillion and $2 trillion figures are the prices he tests, not an offer price. He writes that his own intrinsic valuation will have to wait until the full prospectus is filed. The post we read does not link a valuation spreadsheet. We did not contact Damodaran or Anthropic.
The Bottom Line
Damodaran writes that the metric investors have focused on for Anthropic is revenue, and lately ARR, and his table puts a $2 trillion price at 30.77 times a $65 billion run rate and 6.67 times $300 billion of expected 2030 revenue. On the trade itself, he writes: “I will not be taking sides here.”
What happened next (29 Oct): after Anthropic filed its prospectus, Damodaran published his valuation on 28 Oct: he estimates the value of Anthropic’s equity at $1.475 trillion, “at the lower end of the offer pricing range ($1.5 to $2 trillion)”; by our arithmetic, that is about 32 times Anthropic’s second-quarter 2026 revenue annualized.
