The $42 billion net loss in Anthropic’s draft prospectus is not an Anthropic IPO price prediction, and it is not cash that left the business. Reuters, which reviewed the confidential filing, reported on September 28, 2026, that roughly $34 billion of that 2025 figure was an accounting charge on financing that can convert into shares, while revenue grew 12-fold to nearly $4.6 billion and the operating loss widened to $8.06 billion. The per-share number that follows from the last primary round is a different object. Forge Global’s funding table shows the May 28, 2026 Series H struck at $589.01 a share against a $965 billion post-money valuation, a pair that implies about 1.64 billion shares. Reuters reported on September 29 that Anthropic is seeking a valuation of about $2 trillion. Divided by that share count, the ask is about $1,221 a share, not the higher figure that appears when a later secondary print is mistaken for the round price.
That $1,221 still has to clear a compute book the loss line does not capture. Anthropic expects to spend at least $518 billion over a decade with six infrastructure partners, and about 80 percent of that sum is non-cancelable or payable whether or not the capacity is used, Reuters reported on September 29. Year-end 2025 cash, cash equivalents and short-term investments were $20.28 billion. On the same 1.64 billion shares, the non-cancelable stack is about $253 a share sitting under a $1,221 price, against about $12 of cash. The equity being discussed is a claim on growth that has to service a take-or-pay book equal to about a fifth of the $2 trillion headline. Anthropic has not set an offer price, a share count or a listing date, and it declined to comment on the filing.

Quick take: The operative price here is about $1,221 a share at a reported $2 trillion valuation, using the May 28 Series H price of $589.01, not the $42 billion loss.
What’s actually happening
Anthropic is still private. It confidentially submitted a draft registration statement in June 2026, and Reuters reported on September 29 that the paperwork has not been publicly disclosed. What changed at the end of September is that Reuters reviewed the confidential prospectus. Anthropic declined to comment on September 28. The $2 trillion figure was already in circulation in August, as covered in FinanceFeeds’ note on that pitch.
Three prices are in circulation, and they are not the same object. The primary price is the Series H. Reuters’ September 28 timeline says the company raised $65 billion in May at a $965 billion post-money valuation. Forge‘s May 28 table shows Series H-1 and H-2 both at $589.01 against that figure. Dividing $965 billion by $589.01 produces about 1.638 billion shares, an implied count, not a published one. The 70.1 million H-1 shares are the $41.29 billion tranche, not the company. The same page also lists H-2 at $18.2 billion, still at $589.01, plus H-3 at $1.94 billion and $20.93 and H-4 at $3.57 billion and $50.48. Those four amounts add to $65 billion. The cheaper prices are not used here.
The second price is a secondary screen, and it does not clear. Nasdaq Private Market‘s page on September 30 showed an estimate of $80.61 as of September 11, a last trade of $234, a bid of $260.80 and an offer of $188.50. Those prints match neither each other nor $589.01, and Forge says its indicative price is not yet available. Dividing $965 billion by a higher secondary print invents fewer shares and a higher IPO price.
The third price is the reported listing case. Reuters wrote on September 28 that the sale could value Anthropic at more than $2 trillion, and on September 29 that the company is seeking about $2 trillion. Neither line is an offer price. On 1.638 billion shares, about $2 trillion is $1,220.75, or about $1,221. Any Anthropic IPO price prediction that uses only the loss, or only one revenue multiple, is mixing clocks that do not match.
Obviously a $2 trillion valuation sounds outlandish, but when you break it down to a multiple of sales, likely to be around 18-20x, it sounds much more reasonable than the recent SpaceX IPO.
— Michael Field, Chief Equity Strategist at Morningstar, September 29, 2026
Quick take: $1,221 is $2 trillion divided by the shares implied by a $589.01 round price. It is a FinanceFeeds calculation, not a price Anthropic has posted.
Who is doing what
Amazon, Google and Microsoft sit on every side of the trade. The filing, as Reuters read it on September 29, calls them investors, customers, cloud providers, distributors and competitors, and says that mix creates incentives that “may not be fully aligned” with Anthropic’s interests. Sales through Amazon and Google were $2.16 billion in 2025, 47 percent of revenue. Anthropic paid roughly $351 million back in distribution fees. Amazon declined to comment. Anthropic and Alphabet did not respond.
The contracts dwarf that revenue. Reuters reported minimums of at least $111.1 billion with Google from April 2026 to July 2033, $110 billion with Amazon from May 2026 to April 2036, and $31.4 billion with Microsoft from November 2026 to May 2033, described as payable “regardless of usage.” Microsoft’s line “is non-cancelable except in the event of Microsoft’s uncured material breach.” The filing says, “If our actual spend falls short, we must pay Google the difference.” Broadcom-related equipment leases of about $161.2 billion are non-cancelable except in default, and that supplier’s equity is already a public story in Broadcom’s stock.
Some lines can be cut. xAI agreements of up to $84.5 billion through 2029 are largely cancelable on 90 days’ notice, while AMD committed to buy up to $5 billion of stock and to supply capacity expected to exceed $20 billion. About 80 percent of the $518 billion plan does not depend on usage. The filing says future demand will be “limited principally by the availability of compute.”
Forge’s May 28 Series H-1 row, at $589.01, names Altimeter, Amazon, Baillie Gifford, Coatue, Dragoneer, Fidelity, Greenoaks, Sequoia and Blackstone among the buyers. Forge will not transfer shares without company approval, and an unapproved sale would be void. No underwriter is named in the September Reuters reporting.
Control is set before a public vote. Founder LLC, initially the seven co-founders, directs one Class F share with 50.1 percent of voting power on key matters, including some director elections, Reuters reported on September 28. Named members include Dario Amodei, president and board chair Daniela Amodei, Tom Brown and Chris Olah. Dario Amodei’s 2025 pay was nearly $18 million and Daniela’s was $16.4 million. The co-founders pledged 80 percent of their personal equity to charity. The Long-Term Benefit Trust, whose trustees include Ben Bernanke and Richard Fontaine, elects the other four directors.
Massive spending would normally have investors running for the hills, but what’s capturing the market’s attention is Anthropic’s stellar revenue growth, up 12-fold in 2025.
— Dan Coatsworth, Head of Markets at AJ Bell, September 29, 2026
Quick take: About 80 percent of a $518 billion buildout is payable even if usage disappoints.
Market impact and the arithmetic
The multiple is whichever revenue number sits in the denominator. The table uses Reuters figures and Forge’s Series H price. SpaceX is the listed comp because Reuters set Anthropic beside SpaceX’s $1.77 trillion IPO: shares sold at $135, rose 19 percent on the June 12 debut to $160, and recently traded around $147. A separate exercise is in FinanceFeeds’ September 4 OpenAI price note, which used a different share-count method.
| Basis | Figure | At about $2 trillion | Source |
|---|---|---|---|
| 2025 revenue | Nearly $4.6 billion | About 435 times | Reuters, September 28, 2026 |
| July 2026 run rate | Topped $65 billion | About 31 times | Reuters timeline, September 28, 2026 |
| 2028 projection | $190 billion to $200 billion | About 10.5 times to 10 times | Reuters, cited September 28, 2026 |
| Morningstar range | 18 to 20 times sales | Implies about $100 billion to $111 billion of sales | Field, via Reuters, September 29, 2026 |
| Series H price | $589.01 | About $1,221 a share | Forge, May 28, 2026 |
Field’s 18 to 20 times is not a 2025 multiple. Two trillion dollars divided by 20 is $100 billion of sales, and divided by 18 is about $111 billion, above the July run rate and below the $190 billion to $200 billion 2028 projection Reuters reported. On that band, $2 trillion is already about 10 to 10.5 times. OpenAI has said gross marketplace accounting inflates revenue by billions. Anthropic said it is the principal. The $351 million fee is about 8 percent of 2025 revenue, so the dispute does not close the gap between 435 times and 31 times.
On 1.638 billion shares, 80 percent of $518 billion is about $253 a share. The Google, Amazon and Microsoft minimums, $252.5 billion, are about $154. Broadcom’s $161.2 billion of leases are about $98. Cash of $20.28 billion is about $12. AMD’s agreement to buy up to $5 billion of stock is small beside that stack, and the public read-through sits in AMD’s own share price. European tech rose 2.4 percent and the Philadelphia semiconductor index rose 1.5 percent on September 29.
This is positive for the AI trade, since it is fuelled by continued elevated levels of capex spend. The fact that Anthropic is planning on spending big on capex means that the capex cycle is not over yet.
— Kathleen Brooks, Research Director at XTB, September 29, 2026
Quick take: About $2 trillion is roughly 435 times 2025 revenue, roughly 31 times the July run rate, and roughly 10 times the reported 2028 projection. The $1,221 price inherits whichever clock the buyer uses.
Regulatory and listing tension
The listing regulator is the U.S. Securities and Exchange Commission. The document is a confidential draft submitted in June, and Reuters reported on September 29 that it has not been publicly disclosed. Anthropic declined to comment on the prospectus and did not immediately respond on the compute contracts. The company has not published an offer price, an exchange, a ticker or a date. A debut is likely after the November 2026 U.S. midterm elections, Reuters reported on September 28.
The corporate form is a Delaware public benefit corporation. Anthropic’s May 7, 2026 certificate says the benefit is “to responsibly develop and maintain advanced AI for the long term benefit of humanity.” The filing warns that the board may not resolve conflicts among investors, the public benefit and other stakeholders in favor of shareholders. Reuters noted on September 29 that there is no legally required independent audit of the mission. A benefit suit takes at least 2 percent of the stock or $2 million. The same report cited thin case law, Etsy’s 2017 decision not to convert, and a 2026 Delaware ruling that a public benefit corporation need not take the highest reasonable price in a sale.
Voting control sits on that duty. The Class F share, 50.1 percent of votes on key matters, is directed by a majority of the seven co-founders. The filing warns of decisions “that may conflict with short-, medium-, or long-term financial interests and business performance, which may negatively impact the value of our Class A common stock.” The Long-Term Benefit Trust elects four directors. Bernanke’s seat on that trust is already public. Class F and Class A holders together elect the Amodei siblings and one still-to-be-named director.
About 80 pages of a 261-page main body cover risks, against 48 pages on the business. SpaceX used about 38 of 277. Reuters reported on September 28 that Anthropic will caution that advanced AI could pose “catastrophic or existential risks to humanity,” and that models could “resist shutdown,” “conceal or manipulate information,” and show behavior “resembling blackmail.” No SEC comment letter is public. The company has not said how buyers should price that warning, and Reuters’ review of the filing quotes the risk without quoting a method.
Quick take: The SEC has not released the draft, and the shares would carry a Delaware public-benefit duty plus 50.1 percent founder voting control.
What happens next
Three paths follow. Each price is a FinanceFeeds scenario built from sourced inputs, not an offer price. The share count throughout is $965 billion divided by $589.01, about 1.638 billion shares. Change the valuation or that count and every price below moves with it.
Base case, about $1,221, after the November 2026 midterms. Reuters has reported that the sale is likely to wait until after those elections and that the company is seeking about $2 trillion. If it prices near that ask on the May count, the price is about $1,221, 107 percent above $589.01. If new shares equal to 10 percent of the count are sold, the same $2 trillion equity value implies about $1,110. The 10 percent illustrates dilution. Anthropic has not stated a primary size.
Bear case, $589.01, if buyers anchor on the last round. An $8.06 billion operating loss, nearly $4.6 billion of 2025 revenue, two customers at 12 percent each, and about $414 billion payable whether compute is used are already in the filing. If that stack is the constraint, value can sit at the $965 billion mark, or $589.01, about 52 percent under the base case. The path is a slip into 2027 or a range nearer Series H than the reported ask.
Bull case, about $1,465 to $1,740, only if 2028 is underwritten. Reuters reported a 2028 projection of roughly $190 billion to $200 billion. Twelve times $200 billion is $2.4 trillion, about $1,465 a share. Fifteen times $190 billion is $2.85 trillion, about $1,740. Both multiples are FinanceFeeds choices on that band, between the 10 times $2 trillion already implies on $200 billion and the 18 times Field cited. The run rate has to climb from above $65 billion, and buyers have to pay a double-digit multiple on an $8.06 billion operating loss. The Anthropic IPO price prediction in all three paths is a ratio, not a term sheet.
Frequently asked questions
What is the Anthropic IPO price prediction?
About $1,221 a share if Anthropic is valued at about $2 trillion on the count implied by the May 28, 2026 Series H price of $589.01. That count is $965 billion divided by $589.01, or about 1.64 billion shares. It is a FinanceFeeds calculation from Forge’s round price and Reuters’ reported valuation. Anthropic has not set an offer price.
Has Anthropic confirmed an IPO date or a $2 trillion price?
No. Reuters reported on September 29 that Anthropic is seeking about $2 trillion, and on September 28 that the sale could value it at more than $2 trillion and is likely after the November 2026 midterms. The draft filed confidentially in June has not been published. The company declined to comment. There is no exchange, ticker, share count or offer price in that reporting.
Why did Anthropic lose $42 billion in 2025?
Reuters reported that the near-$42 billion net loss included roughly $34 billion of accounting charge on financing that can convert into shares, not cash spent running the business. The operating loss widened to $8.06 billion from $2.98 billion. Compute and infrastructure cost $7.33 billion, more than half of $12.65 billion of operating expenses. The loss line and the cash spent are different numbers.
What was the Series H price per share?
Forge’s table shows $589.01 for Series H-1 and H-2 on May 28, 2026, against a $965 billion post-money valuation. Reuters separately reported a $65 billion raise at that valuation. The $589.01 figure is a preferred round price, not a public quote, and Forge says its indicative price is not yet available.
How does the $518 billion compute bill affect the equity?
Reuters said Anthropic expects to spend at least $518 billion over a decade, with about 80 percent payable regardless of use. On about 1.64 billion shares that is roughly $253 a share, against about $12 of year-end 2025 cash and a $1,221 base-case price. Google, Amazon and Microsoft account for $252.5 billion of minimums. The contracts support the growth story and also absorb equity value.
Can institutions buy Anthropic stock before the IPO?
Only in secondary trades the company approves. Forge says an unapproved transfer would be void and that it will not facilitate a trade without approval. There is no public ticker. Class A shares, once listed, are expected to carry one vote each, but a founder-controlled Class F share would hold 50.1 percent of voting power on key matters.
