The obvious reading of Monday’s filing is that Anthropic stock now has a public price, and that the price is $1,221 or $1,513. That reading is wrong. Anthropic, PBC filed a preliminary Form S-1 on 26 October 2026, and the cover leaves the offering price as a blank between two dollar signs. There is no public market for the Class A common stock. The company has applied to list it on Nasdaq Global Select as ANT. ANT is not trading. One count can be divided: 846,840,960 Class N shares equal 5% of fully diluted shares as of 30 June 2026, assuming the Amazon notes convert, which is 16,936,819,200 shares. On that count the May 2026 company valuation of $965 billion is $56.98, a $1.5 trillion investor discussion is an $88.56 bull, and the February 2026 valuation of $380 billion is a $22.44 bear.
The same pages explain why those older dollar levels cannot be reused. On 17 September 2026 the company effected a 10-for-1 forward split of Class A and Class N, and the prospectus adjusts share and per share figures for that split on a retroactive basis. A pre-split private print near $589, and a title price of $1,221 or $1,513, is the wrong unit on a post-split fully diluted count. The filing also rejects a leaked claim that two customers supplied nearly a quarter of revenue. No single customer represented more than 10% of revenue for the nine months ended 30 September 2026, and about 79% of September-quarter revenue came from outside the top five, up from about 64% in the March quarter. The registration statement, file 333-299633, is not effective. This is a valuation division, not a cash quote.

What the filing changed, and why the obvious price is wrong
The cover says Anthropic is selling Class A shares and that selling stockholders are selling more, then leaves both numbers blank. Delivery in New York is “on or about” a blank. Goldman Sachs and Morgan Stanley lead, followed by J.P. Morgan, Citigroup, Barclays, Wells Fargo Securities, and BofA Securities. A later passage refers to “an assumed initial public offering price of $ per share” and leaves the ownership result blank. The company has not published $1,221, $1,513, $1.5 trillion, or $2 trillion as a range. FinanceFeeds reported the filing on the revenue and the loss. The per share job is separate.
From May to June 2026 the company sold 77,637,878 Series H-1 shares at $589.0095, for proceeds stated as $45,729,447,703. That contractual price was not divided by 10. An April 2026 Class A tender is shown at $25.9136, the older $259.1364 issue price after the split. Dividing the preferred price by 10, only as an illustration, produces $58.90. The base is $56.98. The gap is extra dilution in the 30 June count, including the Amazon conversion the 5% sentence assumes. $965 billion divided by $589.0095 implies about 1,638,343,694 pre-split shares, or about 16,383,436,940 after a 10-for-1, roughly 553 million fewer than the title count. On that pre-split count, $1,221 is about $2.000 trillion and $1,513 is about $2.479 trillion. The earnings denominator, 2,024,972,990 shares, is a third figure and the wrong one: $965 billion on it is about $476.55, and the half’s loss per share is $39.88.
Who is exposed
Class A would list, with one vote. Class N, held mainly by strategic partners, has no ordinary vote and converts to Class A on a sale to an unaffiliated party. Class F is one share for a founder LLC of Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah. It carries 50.1% of votes on ordinary matters and has no economic rights. Class T lets the Long-Term Benefit Trust elect a majority of the board, also with no ordinary economic rights. The company says it will be a controlled company. A Class A buyer does not get control. Each co-founder has pledged 80% of personal equity to philanthropy. The S-1 says the pledges are voluntary and revocable, so the economics can fall while the votes stay. RSU fair value is defined as the offering price, which is blank.
Amazon, Google, and Microsoft are named as cloud partners that can also be investors, customers, and competitors. Amazon rollover notes from 2023 and 2024 had about $6.2 billion of principal on 30 June 2026 and pay no interest. Unless Amazon waives it, conversion stops at 12% of capitalization. Amazon’s listed stock is a separate claim. Broadcom’s five-year lease states rent of about $125.2 billion excluding interest and is non-cancelable except in default, with capacity to issue up to $42.0 billion of notes. Broadcom’s listed shares are the supplier side. Nvidia and AMD supply GPUs beside Amazon Trainium and Google TPUs. The 5% fund is the Class N block already issued to a subsidiary, with a framework for up to 2% more each time the price rises 50% from the IPO price. That add-on has no dollar until a price exists.
What the primary documents show
The S-1 supplies the count, the split, and the blank range. The company site supplies the $965 billion and $380 billion marks. The $1.5 trillion figure is investor talk, not a range the company printed.
| Item | What the document states | What it does not state |
|---|---|---|
| S-1 cover, 26 Oct 2026 | Price per share between a blank and a blank. Listing application for ANT. No public market yet. | No $1,221, no $1,513, no $1.5 trillion, no $2 trillion. |
| Split, 17 Sept 2026 | 10-for-1 on Class A and Class N. Figures retroactively adjusted. | Does not keep the old per share titles as current prices. |
| Public benefit, 30 June 2026 | 846,840,960 Class N shares equal 5% fully diluted. Count used: 16,936,819,200. | Outstanding Class A and Class N lines in the capitalization table are blank. |
| Series H-1 price in the S-1 | 77,637,878 shares at $589.0095. Proceeds $45,729,447,703. | The $965 billion headline is the company announcement, not this line. |
| Series H, 28 May 2026 | $65 billion raised at $965 billion post-money. Run-rate revenue had crossed $47 billion earlier that month. | Run-rate is not GAAP. H1 2026 revenue is $16.3 billion. |
| Series G, 12 Feb 2026 | $30 billion raised at $380 billion post-money. | Not a claim that the business is still worth that after May. |
S-1 revenue, in millions, is $41 in 2023, $386 in 2024, $4,585 in 2025, and $16,286 in the first half of 2026. March was $4,731 million and June was $11,555 million. June operating income was $974 million. March’s operating loss was $1,667 million, so the half lost $693 million on operations, not the $80.748 billion net loss that follows the fair-value line. The filing says: “We do not expect our revenue will continue to grow at comparable rates.” June revenue grew 1,368% while compute expense grew 300%. Trailing revenue per employee was over $6.6 million on 30 September 2026, against $1.4 million a year earlier. The Next Web says the company told investors that third-quarter revenue reached $16.8 billion. That is not an S-1 line. Customers at $100,000 or more went from about 20 in December 2023 to more than 11,900, with the group’s dollar total left blank.
What named people have said, and what the range still does not say
Deepa Seetharaman, who covers AI for Reuters, wrote on 15 October 2026 that some current and prospective investors were disappointed by recent revenue growth. The sentence this piece uses is: “Those investors are starting to think the co should go for a $1.5 trillion valuation, not ~$2 trillion.” The status is on X. Direct fetches of the Reuters and AP stories did not return the articles, so the post is the wording in hand. It is why the bull is $1.5 trillion and not $2 trillion. A $2 trillion case on this count is $118.09. That bar is on the chart. It is not in the title.
The bull is a discussion divided by a count, not a company statement that the shares are worth $88.56. Anthropic’s pages confirm $965 billion and $380 billion. They do not confirm $1.5 trillion. The raw quotient is $88.5644, which rounds half up to $88.56.
Vey-Sern Ling, managing director at Union Bancaire Privee, told Bloomberg a line that The Next Web quotes: “The additional spending plans are positive for the semiconductor supply chain but whether they materialize is highly uncertain.” The page is The Next Web. That article, from the draft period, also says Bloomberg reported marketing as soon as the week of 9 November. That calendar is not a sentence in Monday’s S-1. The public filing leaves the aggregate dollar of purchase commitments as “more than $” with the number blank. The named dollar a reader can foot is the Broadcom lease, about $125.2 billion excluding interest, plus the $42.0 billion note capacity. Ling’s caution applies to plans. It does not fill the blank. The company has declined, by leaving the range empty, to pick a valuation. Several post-conversion ownership percentages are blank as well.
Cash, notes, and the lease the total line does not fill
On 30 June 2026 the company had raised $141.1 billion, held $112.4 billion of cash, and held $19.3 billion of short-term investments. The $131.7 billion sum of the last two lines is arithmetic, not a caption, and it does not mean the lease is pre-funded. The $80.748 billion half-year net loss is not cash out the door. The 2025 net loss was $41.965 billion on $4.6 billion of revenue, and the fair-value line grows when the private mark rises. The operating loss of $693 million is the cleaner read, and it is still a loss. The prospectus says advanced systems could, without safeguards, “pose catastrophic or existential risks to humanity, particularly if such systems were misused, replicated, weaponized, or allowed to operate with a high degree of autonomy.” That mandate, with the trust electing the board majority, can justify spend a conventional board would refuse. The filing also says the cloud and Broadcom ties may draw antitrust scrutiny.
What happens next
Through 31 December 2026 the bull stays $88.56 and the bear stays $22.44 unless an amendment fills the range or changes the count. ANT has no session. Reported timing for a mid-November sale is a plan, not a cover date. The Next Web said on 21 October that Bloomberg had reported marketing as soon as the week of 9 November. That sentence predates the public S-1.
If a listing happens, holders other than co-founders and stockholders above 0.5% are locked until the earlier of the second full trading day after earnings for the quarter ending 31 March 2027, or 180 days after the prospectus date. Co-founders and larger holders run to the earlier of the matching date after the quarter ending 30 September 2027, or 365 days. Goldman Sachs and Morgan Stanley can waive early. The intervals start only when a prospectus date exists.
If the second half only repeats $16.286 billion, full-year revenue is about $32.6 billion. The base would be about 29.6 times that, the bull about 46.1 times, and the bear about 11.7 times. The May run-rate of $47 billion is a different measure, and $965 billion is about 20.5 times it. The company has said comparable growth should not be extrapolated. Models released in the six months ended 30 September 2026 were over 80% of September-quarter revenue. Spend in the two weeks ended 2 January 2026 fell about 20% from the prior two weeks.
Bull, base, and bear
The cited mark is $56.98, the 28 May 2026 valuation of $965 billion divided by 16,936,819,200. It is not a cash close. Round half up: $380 billion is $22.44, $965 billion is $56.98, $1.5 trillion is $88.56, and $2 trillion is $118.09. The bull is 55.42% above the mark. The bear is 60.62% below it. Fewer than 30 private prints were saved, so the listed-stock formula was not used. A crypto perpetual is not the spot.
| Case | Price | Versus the $56.98 mark | What has to be true |
|---|---|---|---|
| Bull | $88.56 | 55.42% above | The $1.5 trillion investor discussion Seetharaman reported on 15 October, a step down from about $2 trillion, is divided by this S-1 count. An amendment does not introduce a different count or a lower range. |
| Base | $56.98 | The mark | The last company-confirmed valuation remains the 28 May 2026 Series H post-money of $965 billion, on the 30 June fully diluted count. |
| Bear | $22.44 | 60.62% below | The value that clears on this same count is the 12 February 2026 Series G post-money of $380 billion. That is a prior round, not a forecast that operations returned to February. |
The chart is four reported valuations and four quotients. It is not a price history, and it has no moving average, because ANT has no daily close.
FAQ
What is the Anthropic stock prediction after the S-1?
The Anthropic stock prediction is an $88.56 bull and a $22.44 bear. Both prices use 16,936,819,200 fully diluted shares from the Form S-1 filed on 26 October 2026. The bull divides a $1.5 trillion investor discussion by that count. The bear divides the February 2026 valuation of $380 billion by the same count. The base is $56.98, from the May $965 billion round. ANT is not trading, and the offering price on the cover is blank.
Why is the prediction not $1,221 or $1,513?
$1,221 and $1,513 are the wrong unit after the 17 September 2026 split. The prospectus adjusts share and per share figures for a 10-for-1 forward split. On the pre-split count implied by a $589.0095 price and the $965 billion round, $1,221 is roughly a $2 trillion mark. On the June fully diluted count a $2 trillion case is about $118.09, and this title does not use it. The bull defended here is the $1.5 trillion discussion, at $88.56.
Is ANT trading on Nasdaq?
No. The S-1 says there has been no public market for the Class A common stock and that Anthropic has applied to list on the Nasdaq Global Select Market under ANT. The registration statement is not effective. There is no listed close to wait for on 27 October 2026 or on any later session until trading actually starts. A private mark is not a Nasdaq close, and a crypto perpetual is not the stock.
Did the S-1 set a $1.5 trillion valuation?
No. The S-1 does not set a $1.5 trillion valuation or a $2 trillion valuation. The price range is blank. The $1.5 trillion figure is an investor discussion that Reuters correspondent Deepa Seetharaman described on 15 October 2026 as a step down from about $2 trillion. The $965 billion and $380 billion figures are company announcements from May and February. Dividing them by the filing’s share count is this desk’s arithmetic, not an offering price.
Which share count is in the title?
The title uses 16,936,819,200 shares. The S-1 says 846,840,960 Class N shares equal 5% of fully diluted shares as of 30 June 2026, assuming the Amazon notes convert in full. A second count, about 1.64 billion pre-split shares implied by $589.0095 and $965 billion, is shown above and is not used for the bull or the bear. The earnings-per-share denominator of about 2.02 billion shares is not the valuation count either.
What would change the bull and the bear?
An S-1 amendment that fills the price range, or that states a different fully diluted count, would replace $88.56 and $22.44. A new company-confirmed valuation would replace the $56.98 base. A roadshow date would not, by itself, change the division. The lock-up intervals start from the prospectus date and from later earnings releases, and they do not set the per share cases used here.
