Anthropic is no longer just talking about an IPO: it filed its S-1 publicly on October 26, 2026, and plans to list on the Nasdaq Global Select Market under the ticker ANT. The $2 trillion valuation that dominated headlines in September is now the top of the conversation rather than the base case. As of November 3, The Wall Street Journal reports that large investors want pricing closer to $1.5 trillion to $1.6 trillion, with a roadshow that could start the week of November 9 and a debut targeted for the week before Thanksgiving.
The revenue chart is still the core of the pitch, and the filing confirms it is real: revenue jumped from about $1.2 billion in the first half of 2025 to $16.3 billion in the first half of 2026. What the filing adds is everything a revenue chart leaves out, from a giant accounting loss to nearly $900 billion in compute commitments. Here is what we know, what changed since our first report, and what to watch before the shares price.
Key takeaways, updated November 3, 2026
- S-1 filed October 26, 2026, ticker ANT on Nasdaq, with Goldman Sachs and Morgan Stanley leading the deal
- Valuation talk has slipped from about $2 trillion to a reported $1.5 trillion to $1.6 trillion investor target; Anthropic has not set a price range yet
- Q3 2026 revenue was about $17 billion, up roughly 47% from Q2, according to the WSJ
- Trailing four quarter revenue is about $35.3 billion, per Fortune, so $1.5 trillion would mean paying more than 40 times trailing sales
- First half net loss was $80.7 billion, but about $72.4 billion of it is a noncash fair value charge, not cash burn
- Timing: roadshow possibly the week of November 9, listing possibly the week of November 16
Where the Anthropic IPO stands right now
The process has moved quickly. In September, reports had Anthropic pushing its target from October to November so it could show investors one more quarter of results. That is what happened. The company made its registration statement public on October 26, then shared third quarter numbers with investors at the start of November.
The filing names the Nasdaq Global Select Market as the venue and ANT as the ticker. Goldman Sachs and Morgan Stanley are the lead bookrunners in a syndicate of roughly 20 banks that includes J.P. Morgan, Citigroup, Barclays, Wells Fargo, BofA Securities, Deutsche Bank, RBC and UBS, according to IPO Scoop. Dataconomy reports that JPMorgan is leading sales to individual US investors. The number of shares and the price range were left blank in the initial filing, which is normal at this stage.
If you want the plain timeline of how Anthropic got here, from its first funding rounds to the bank mandates, our explainer on when Anthropic is going public covers the background. This article focuses on the valuation and the numbers behind it.
Why the $2 trillion figure is under pressure
The $2 trillion number came from banker conversations reported over the summer and early fall. It was never a price range set by the company. Since then two things changed.
First, the market. Tech stocks sold off hard at the end of October. Dataconomy notes the Nasdaq Composite closed nearly 3% lower on October 30, capping its worst month since March 2025, while several large tech names fell after earnings that signaled heavier AI spending. Investors who already hold plenty of AI exposure are less eager to pay any price for more.
Second, the filing itself. Once the S-1 put compute costs and commitments on paper, the debate moved from how fast revenue grows to how much it costs to produce. The WSJ reports that investors preparing to buy shares cited volatile markets, growing AI exposure, political opposition to new data center construction and uncertainty about when cloud spending pays off. Some told bankers they see $1.4 trillion to $1.5 trillion as fair, while about $1.75 trillion is still seen as possible, according to Dataconomy.
Even the lower range is a big step up from the private market. Anthropic’s last private round valued it at about $965 billion, so a $1.5 trillion listing would still be a gain of more than 50% for late private investors.
What the S-1 shows about revenue and losses
The numbers that matter most come straight from the filing and from the third quarter update shared with investors.
| Metric | Figure | Source |
|---|---|---|
| Revenue, full year 2025 | About $4.6 billion | S-1, via AI Weekly |
| Revenue, first half 2025 | About $1.2 billion | S-1 |
| Revenue, first half 2026 | $16.3 billion | S-1 |
| Revenue, Q2 2026 | About $11.6 billion | S-1, via AI Weekly |
| Revenue, Q3 2026 | About $17 billion (+47% vs Q2) | WSJ |
| Trailing four quarter revenue | About $35.3 billion | Fortune |
| Operating loss, first half 2026 | $693 million | S-1 |
| Net loss, first half 2026 | $80.7 billion, incl. $72.4 billion noncash charge | S-1 |
| Cash and short term investments, Sept. 30 | About $131.8 billion | Fortune |
| Compute purchase and lease commitments | About $895.4 billion | WSJ |
Figures as reported through November 3, 2026. Q3 numbers were shared with investors and reported by the WSJ and Fortune; they are not audited annual results.
The $80.7 billion loss, explained
The headline net loss looks alarming, but most of it is accounting. Anthropic raised money for years through convertible notes, SAFEs and similar instruments. As the company’s valuation soared, the fair value of those instruments rose, and the change runs through the income statement as a loss. That charge was about $72.4 billion in the first half of 2026 alone. It does not represent cash leaving the business.
The operating picture is far closer to break even. The first half operating loss was $693 million, and Q2 on its own produced operating income of about $974 million. Cash from operations was $3.93 billion in the first half and about $6.6 billion across the first nine months of the year, according to Fortune.
Run rate versus revenue
Much of the 2026 coverage, including ours, leaned on annualized run rate figures, such as the roughly $65 billion run rate Bloomberg reported for the end of July. The S-1 defines run rate as consumption fees from the trailing 28 days multiplied by 13, plus monthly subscription fees multiplied by 12. It is a snapshot, not a year of booked revenue. The audited and reported quarterly figures above are the better basis for valuation math.
The costs behind the growth
Compute is the story investors are now reading most closely. Compute and infrastructure expense was $8.95 billion in the first half of 2026, up from $2.33 billion a year earlier. In the third quarter it climbed about 77% to $9.9 billion, with roughly $5 billion coming from short term capacity purchases, Fortune reports. That pushed the adjusted operating margin down to 15% from 19% in Q2.
The longer term number is bigger still. The WSJ puts Anthropic’s computing purchase commitments and lease agreements at about $895.4 billion, nearly half of it expected before the end of 2030. That figure explains why the IPO raise is so large, and why concerns about power and data center buildouts, including proposals like the Bernie Sanders bill that would halt data center construction, show up in investor conversations about AI valuations. Physical supply risk matters too: our coverage of how conflict threatens global chip supplies and AI expansion applies directly to a company whose main cost is compute.
Customer concentration is the other risk the filing surfaces. About 20% of first half revenue came from two unnamed customers, down from nearly 25% in 2025, according to The Information as cited by AI Weekly. Anthropic sells heavily through Amazon, Google and Microsoft cloud platforms, but the filing does not say who the two customers are.
Valuation math: what $1.5 trillion to $2 trillion implies
Fortune ran the simplest version of the math. At $1.5 trillion to $2 trillion, buyers would pay about $43 to $57 for every dollar of trailing revenue. University of Florida IPO expert Jay Ritter told Fortune that only 14 of 4,110 IPOs from 1980 to 2024 came to market at a comparable price to sales level, and those trailed the broader market by an average of 15.4% over holding periods of up to three years. He said a valuation above $1.4 trillion would require a credible path to at least $100 billion in annual profit after tax.
Not everyone thinks the number is unreasonable. NYU Stern professor Aswath Damodaran published a model on October 28 that assumes $1 trillion in annual revenue by 2036 and a 27.5% operating margin, which produced an equity value of about $1.475 trillion. He told Fortune the Q3 figures gave him little reason to change it. Tomasz Tunguz of Theory Ventures noted that rising compute costs will pressure margins, but that implied gross margin is still a healthy level.
| Valuation | Multiple of ~$35.3B trailing revenue | Context |
|---|---|---|
| $965 billion | About 27x | Last private round |
| $1.475 trillion | About 42x | Damodaran estimate |
| $1.5 to $1.6 trillion | About 42x to 45x | Reported investor target |
| $2 trillion | About 57x | Earlier banker talk |

Who controls Anthropic after the IPO
Public shareholders will buy economics, not control. Analyses of the S-1, including one published on HackerNoon, describe a share structure with several classes. Class A shares sold in the IPO carry one vote each. A single Class T share held by the Long-Term Benefit Trust, a body of financially disinterested trustees, elects directors who form a board majority. A single Class F share held by an entity owned by the cofounders carries 50.1% of voting power on general stockholder matters. Anthropic is also a public benefit corporation, which lets the board weigh its stated mission alongside shareholder returns.
For ordinary investors that means the usual levers, such as voting out the board, will not work the way they do at most listed companies. It is the same tradeoff buyers accepted at Meta and Alphabet, with an added safety oriented trust on top.
If you are thinking about buying ANT shares
- Wait for the price range. The amended S-1 will show the share count and range, which tells you the real valuation on offer
- Expect limited IPO allocations. Most shares in large offerings go to institutions; retail access through brokers is usually small and not guaranteed
- Watch the first trading days. Mega IPOs often swing hard after listing, and buying at the open is not the same as buying at the offer price
- Read the risk factors. Compute commitments, customer concentration and governance are all spelled out in the filing
- Size the position. A single stock at more than 40 times sales is a high risk holding, not a core position
This is general information, not investment advice.
What to watch before pricing
- The price range in the amended filing. It turns valuation reports into an actual number.
- The size of the raise. Reports have ranged from about $75 billion (IPO Scoop) to roughly $100 billion (Dataconomy). Either would rank among the largest IPOs ever.
- Q4 commentary. Growth slowed from earlier quarters even as it stayed high, so any guidance on the current quarter will matter.
- Market conditions in mid November. A weak tape could push the deal lower or later.
- OpenAI. Anthropic’s main rival is building agent products such as OpenAI Frontier for managing enterprise AI agents, and enterprise share is what the Anthropic valuation is really betting on.
The bottom line
Anthropic’s growth is real and now documented in an SEC filing: from about $4.6 billion of revenue in 2025 to roughly $35 billion over the last four quarters. The $2 trillion valuation, though, was always a target floated by bankers, and the first reaction from buyers points lower. Whether the stock prices at $1.5 trillion or higher will depend less on the revenue chart than on margins, compute commitments and the mood of a market that just had a rough October.

FAQ
When is the Anthropic IPO date?
Anthropic has not set a final date. As of November 3, 2026, The Wall Street Journal reports the roadshow could start the week of November 9, with a Nasdaq debut targeted for the week before Thanksgiving, which is the week of November 16.
What is the Anthropic stock ticker?
Anthropic plans to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT, according to its S-1 filed on October 26, 2026.
Is Anthropic still targeting a $2 trillion valuation?
The $2 trillion figure came from banker discussions and was never a set price range. Investors preparing to buy shares now want a valuation closer to $1.5 trillion to $1.6 trillion, according to the WSJ. The final number depends on the price range and demand during the roadshow.
How much revenue does Anthropic make?
Anthropic reported $16.3 billion of revenue in the first half of 2026 and about $17 billion in the third quarter. Revenue for the last four quarters was about $35.3 billion, compared with about $4.6 billion for all of 2025.
Is Anthropic profitable?
Not on a net basis. It reported an $80.7 billion net loss for the first half of 2026, but about $72.4 billion of that was a noncash charge tied to convertible notes. Operating results were near break even, with a $693 million first half operating loss and operating income in Q2.
Can regular investors buy Anthropic IPO shares?
Possibly, but in limited amounts. JPMorgan is reported to be leading sales to individual US investors, and some brokers offer IPO access programs. Most shares in a large offering go to institutions, so many retail investors will only be able to buy once trading starts.
