Anthropic Eyes November 16 IPO Week as Valuation Talk Drops 40%

Anthropic has cut its expected IPO valuation by up to 40% in two weeks—talks have slid from $1.5 trillion to $2 trillion down to $1.1 trillion to $1.3 trillion—yet it's still pressing for a Nasdaq listing as early as the week of November 16, potentially the largest AI initial public offering to date.

The company, backed by Google and Amazon, could begin formally marketing the offering as early as Tuesday, November 10, once a 15-day waiting period expires after its public filing last month, according to Investing.com analysis. Lead underwriters Goldman Sachs and Morgan Stanley are targeting a debut on the Nasdaq Global Select Market before Thanksgiving on November 26.

Why did the valuation drop?

The market moved underneath the deal. The Nasdaq 100 fell 14% over the same two-week stretch, and the Cboe Volatility Index briefly rose above 25—a level where Renaissance Capital's Matt Kennedy says companies typically postpone IPOs—before retreating to 20.73.

Anthropic could still delay if conditions worsen, but walking away now would raise questions about appetite for large AI listings. "It just becomes a matter of where it prices," Kennedy said.

At the discussed $1.1 trillion to $1.3 trillion valuation against an annualized Q3 revenue run rate of roughly $67.8 billion, the deal prices at about 16x to 19x run-rate sales.

What do the financials show?

Anthropic's amended S-1, dated November 3, lays out rapid growth with a decelerating edge:

• Q3 revenue of $16.96 billion, up 47% sequentially from $11.56 billion in Q2—but down sharply from 144% sequential growth in the prior quarter
• Nine-month revenue of $33.24 billion, roughly 13 times the year-earlier period
• A Q3 operating loss of $567 million, reversing a $974 million operating profit in Q2
• $95.6 billion in cash and $36.3 billion in short-term investments as of September 30

Customer concentration runs high: the top five accounts generated a quarter of revenue in the first nine months. Adoption is broadening fast, though—more than 11,900 customers now spend at least $100,000 annually on a trailing-12-month basis, up from 950 a year earlier.

Growth is real, but the momentum line is bending.

How heavy is the compute bill?

Compute costs fell from 172% of revenue to 57% year over year, a shift the company cites as evidence of operating leverage. The offset is staggering: purchase and lease commitments—almost entirely for compute capacity—total approximately $895.4 billion, with roughly $70 billion due within 12 months. The obligations span contracts with Microsoft, Google, Amazon and SpaceX, and the filing states capital expenditures are expected to "increase significantly" for the foreseeable future.

Anthropic says current cash reserves are sufficient for 12 months but warns it "may be required to seek additional financing sooner than we currently anticipate."

The leverage story is improving; the balance sheet commitment behind it is enormous.

What are the risks and the bull case?

The prospectus flags three primary risks: decelerating growth at a time when investors are paying for years of future expansion; political uncertainty around data-center permitting and power access following Democratic midterm gains; and potential AI-safety regulation that diverges from Anthropic's preferred framework.

Supporters point to the cash pile, broad enterprise adoption, and the thesis that companies will pay a premium for models that reason more reliably and run autonomously longer. Baillie Gifford's Peter Singlehurst and Shaires Holdings CEO Vivek Seth have called Anthropic a generational opportunity. And a lower entry valuation leaves more upside for public investors, one analysis noted.

The deal structure keeps the price range blank, letting investors signal demand through bids—a contrast to SpaceX's fixed-price $86.2 billion IPO in June. Retail participation may reach 20% of shares across the U.S., U.K., Japan and Australia.

What does this mean for the sector?

Anthropic's reception will test whether public markets can absorb the largest AI listing yet. A strong order book would lift suppliers and infrastructure partners such as Alphabet and Nebius; a weak one would deepen doubts about whether AI valuations can hold. OpenAI is widely expected to follow with its own listing, making Anthropic's pricing a template for private AI valuations.

Early order-book quality and the final price range will say more than the headline size.
