Anthropic Targets November IPO as Valuation Expectations Drop Sharply

Anthropic is pressing ahead with plans for a Nasdaq listing as early as the week of November 16, moving toward what could be the largest AI initial public offering to date even as market volatility forces a substantial downward revision in valuation expectations.

The company, backed by Google and Amazon, may begin formally marketing its offering as early as Tuesday, November 10, following the expiration of a 15-day waiting period 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 the Thanksgiving holiday on November 26.

Valuation talks cut by up to 40%

Investor discussions have shifted markedly in the past two weeks. As recently as early November, potential backers discussed a valuation of $1.5 trillion to $2 trillion. By Friday, that range had fallen to $1.1 trillion to $1.3 trillion, a drop of roughly 15% to 40% depending on the benchmark, according to Investing.com analysis. The Nasdaq 100 fell 14% over the same period, and the Cboe Volatility Index briefly rose above 25—a level at which Renaissance Capital's Matt Kennedy says companies typically postpone IPOs—before retreating to 20.73.

The company could still delay if conditions deteriorate further, though abandoning the timetable now could raise concerns about appetite for large AI listings. "It just becomes a matter of where it prices," Kennedy said.

Financials show rapid growth but decelerating momentum

Anthropic's amended S-1 filing, dated November 3, reveals revenue of $16.96 billion in the third quarter, up 47% sequentially from $11.56 billion in the second quarter. That sequential growth rate is down sharply from 144% in Q2. Nine-month revenue reached $33.24 billion, roughly 13 times the year-earlier period.

The company reported an operating loss of $567 million in Q3, reversing a $974 million operating profit in Q2. Purchase and lease commitments—almost entirely for compute capacity—total approximately $895.4 billion, with roughly $70 billion due within 12 months.

As of September 30, Anthropic held $95.6 billion in cash and $36.3 billion in short-term investments. Annualizing Q3 revenue yields a run rate of about $67.8 billion, placing the discussed $1.1 trillion to $1.3 trillion valuation at roughly 16x to 19x that run rate.

Customer concentration remains high: the top five accounts accounted for a quarter of revenue in the first nine months. The company counts 11,900-plus customers spending at least $100,000 annually on a trailing-12-month basis, up from 950 a year earlier.

Compute costs improving but commitments staggering

Compute costs fell from 172% of revenue to 57% year over year, a shift the company cites as evidence of operating leverage. However, the scale of non-cancellable infrastructure obligations—spanning contracts with Microsoft, Google, Amazon and SpaceX—means capital expenditures are expected to "increase significantly" for the foreseeable future, the filing states.

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

Risks and the bull case

The prospectus highlights 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 regulatory intervention on AI safety that could diverge from Anthropic's preferred framework.

Supporters point to the cash position, broad customer adoption, and the argument that enterprises will pay a premium for models that reason more reliably and operate autonomously for longer periods. Baillie Gifford's Peter Singlehurst and Shaires Holdings CEO Vivek Seth have characterized the company as a generational opportunity. A lower valuation could also leave more upside for public investors, one analysis noted.

The offering structure leaves the price range blank, allowing investors to 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.

Read-through to the sector

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

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