Anthropic, the maker of Claude, is preparing what could be the largest IPO on record, at a valuation reports put between $1.5 trillion and $2 trillion. The stakes reach beyond one company: Amazon, Google and Microsoft are at once its investors, its suppliers and its sales channels, and its listing will be a public test of the AI spending boom. It made its IPO filing public on Oct. 26. This page tracks the filing, the valuation and the risks, and what each possible outcome would mean for the US economy.

Risk to the US EconomyUpdated
ELEVATEDAnthropic's IPO is on track for November, but its filing shows heavy losses, huge fixed computing bills and a disputed valuation

Anthropic made its IPO filing public on Oct. 26, after filing confidentially in June. It could list as soon as mid-November, at a valuation reports put between $1.5 trillion and $2 trillion. The filing shows fast revenue growth alongside large losses, most of them accounting charges, and hundreds of billions of dollars in long-term computing commitments to Google, Amazon, SpaceX, Microsoft and others. The price range and share count are still blank.

ContainedLow risk to the economy: the IPO lists near its target and trades steadily.
ElevatedRisk is building: the IPO is on track but untested, its valuation disputed, its filing heavy with losses and fixed commitments.
HighHigh risk: the IPO falls short (delayed, downsized, priced below range or trading well under its IPO price), with spillover to its partners.
SevereSevere risk: the IPO is pulled or fails, with spillover into the wider economy: partners cut commitments, other AI listings are shelved, credit tightens.

IPO clock and pricing signals

When the IPO could happen and at what value, from the filing rules and attributed reporting. We update it as filings land. These are signals for our risk rating, not a prediction.

When could it list?
NovDecJanReported target (Bloomberg)Reported target (Bloomberg): Nov 9–Nov 25Earliest pricing (filing rules)Nov 16June 30 figures go staleNov 11Holiday lullOur slip windowOur slip window: Jan 5–Jan 12Today

Public S-1 filed Oct 26. Earliest pricing is about three weeks after it appears. As of Oct 26.

At what value? (trillions of dollars)
HighElevatedContained$0T$0.5T$1T$1.5T$2T$2.5TNew Constructs estimate$150BLast private round (May)$965BInvestors pushing for$1.5TEarly backer: pricing$1.8TReported target$2TEarly backer: first trades$2.3T–2.4T

Shading shows where a pricing would move our rating. The per-share price range is not set yet; it will appear in an amended S-1.

  • Public S-1 filed: Oct. 26 (SEC EDGAR). Anthropic has applied to list Class A shares on Nasdaq under the symbol “ANT”; the price range and share count are not yet set.
  • Earliest possible pricing: mid-November. The law requires the public filing at least 15 days before the roadshow, so marketing could start Nov. 10 at the earliest (Yahoo Finance). SpaceX priced 23 days after its public S-1 this year (SEC EDGAR); the same pace would mean pricing around Nov. 18.
  • Reported target: marketing as soon as the week of Nov. 9 and trading before Thanksgiving, according to Bloomberg (via Yahoo Finance).
  • Key date, Nov. 11: financial statements in an IPO filing go stale after 134 days (Deloitte). The S-1’s financial statements run through June 30, and it leaves blanks where third-quarter figures will go (S-1). A listing after Nov. 11 needs those figures added in an amended filing.
  • Our estimate: a listing before Thanksgiving is still possible. It needs an amended S-1 with a price range and third-quarter figures. If neither appears by about Nov. 11, a listing before Thanksgiving is unlikely, December is squeezed by the holidays, and the earliest realistic window becomes Jan. 5–12.

Pricing signals

  • Reported target: about $2 trillion (Reuters, via The Star). Some investors are pushing for about $1.5 trillion (Reuters, via CP24).
  • One early backer, a venture investor who spoke anonymously, expects pricing “at around $1.8 trillion” and first trades at $2.3 trillion to $2.4 trillion (Fortune).
  • Last private valuation: $965 billion in May, when Anthropic raised $65.2 billion (S-1; Orrick).
  • What share price each valuation implies (our estimate, not the company’s):
    ValuationPrice per share
    $965 billion (May, Series H)~$57
    $1 trillion~$59
    $1.5 trillion~$89
    $1.75 trillion~$103
    $2 trillion~$118
    $2.5 trillion~$148
    Based on about 16.9 billion fully diluted shares as of June 30: the S-1 says 846,840,960 shares given to its Public Benefit Fund are 5% of the total (S-1). Series H investors paid $589.01 per preferred share, which converts 10 to 1, or about $58.90 a share on May’s smaller share count. New shares sold in the IPO would lower each price slightly (about $4 a share for a $75 billion raise). The actual price range will come in an amended filing.
  • Per-share price range: still blank in the S-1. It will appear in an amended filing; SpaceX's came about 10 days before pricing.

How pricing would move our rating

  • Priced at or above about $1.8 trillion, with trading that holds: toward Contained.
  • Priced between about $1.5 trillion and $1.8 trillion: stays Elevated.
  • Priced below about $1.5 trillion, downsized, or trading below the IPO price: toward High.

What would change this assessment

The rating measures the risk Anthropic's IPO poses to the US economy, judged on events we can document, not on our view of what the company is worth. Any one of these would move it.

  • seenThe public filing: Anthropic filed its S-1 on Oct. 26. It confirms the main figures first reported from leaked drafts; the price range and share count are still blank.
  • not seenDown to Contained: the IPO prices within or above its range, near its target valuation, and trades steadily through its first weeks.
  • not seenUp to High: a delay past year-end, a smaller offering, pricing below the range, or shares trading well below the IPO price.
  • not seenUp to High: stress at the companies on the other side of Anthropic's commitments, such as share or bond selloffs at computing partners tied to the IPO.
  • not seenUp to High: SpaceX ends, cuts or reprices Anthropic’s compute contract.
  • not seenUp to Severe: the IPO is withdrawn or postponed indefinitely.
  • not seenUp to Severe: computing partners cut or renegotiate Anthropic's commitments, or another major AI listing is shelved, citing Anthropic's offering.

Three ways this can go

The outcomes we are watching for, what each would look like, and what we have seen so far.

OutcomeWhat we would seeRisk to the economy
1. The IPO doesn't happenAn amended S-1 with a price range never appears, the roadshow is postponed without a new date, or the offering is withdrawn. So far: the schedule has slipped from October to November (WSJ, via Crypto Briefing), but Bloomberg reports marketing could start the week of Nov. 9 (Yahoo Finance).High
2. It happens but falls short or slumpsA smaller raise, a price range below the reported target, pricing at the bottom of the range, or shares falling after listing. So far: some existing and prospective investors have argued for about $1.5 trillion instead of $2 trillion after third-quarter results fell short of expectations (Reuters, via CP24).High
3. It happens at the hoped-for valuationPricing at or above about $2 trillion and steady trading. So far: Anthropic made its S-1 public on Oct. 26, and attendees at its Oct. 14 investor day came away optimistic, Reuters reported (via KFGO).Lower near term

Potential impacts of an IPO shortfall or failure

No central bank or the IMF models an Anthropic IPO directly. Several have published scenarios for the wider AI correction that a failed or sharply repriced listing could feed into. The ranges below come from those reports.

ImpactWhat the reports describe
Low
Contained repricing		A listing below the roughly $2 trillion target that markets absorb. The Bank of England judges that “an equity shock in isolation would be unlikely to present a direct risk” to UK financial stability (Bank of England, July). In the European Central Bank’s private-credit stress test, euro-area banks’ losses do not exceed “1.3% of total equity” (ECB, May). JPMorgan Asset Management expects heavy AI borrowing to cause “some indigestion,” not “a credit crisis” (JPMorgan).
Medium
The financing window narrows		Share sales stop funding AI growth, pushing more of it onto debt. The Bank of England, noting that AI companies are turning to IPOs, says equity financing “could be positive for financial stability” because “equity capital can preserve debt capacity” (Bank of England). The Financial Stability Board expects $800 billion of AI spending through 2028 to come from private credit (FSB). The IMF counts about $650 billion of debt in circular deals among AI firms and warns that rising leverage could bring “forced selling and surges in equity volatility and credit spreads” if AI profits disappoint (IMF, October).
High
Trigger for a broad AI correction		In the Bank of England’s near-term scenario, US stocks fall 45% over six quarters, corporate credit spreads widen 350 basis points, the dollar weakens persistently and UK output falls 2.2 percentage points (Bank of England). In the IMF’s “market correction” scenario, US stocks fall 20% and world output is 1.1% lower by 2028, 1.8% in the US (IMF). The Bank of Japan’s Oct. 23 stress test assumes AI-related US stocks fall about 50% and BBB corporate spreads widen about 1,100 basis points (Bank of Japan). The IMF’s global bank stress test, which pairs an AI correction with higher interest rates and an energy shock, finds banks holding 22% of global banking assets falling below a 7% capital ratio (IMF).

What is actually known

  • The filing is public. Anthropic filed its S-1 on Oct. 26 (SEC EDGAR), after saying on June 1 that it had “confidentially submitted a draft registration statement on Form S-1” (Anthropic). It has applied to list Class A shares on the Nasdaq Global Select Market as “ANT.” Goldman Sachs and Morgan Stanley lead 22 underwriters. The price range and share count are still blank.
  • The S-1 confirms the numbers first reported from leaked drafts. Revenue rose from $386 million in 2024 to $4.6 billion in 2025, and to $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier. The net loss was $42.0 billion in 2025 and $80.7 billion in the first half of 2026 (S-1). Sales through cloud providers’ marketplaces were 47% of revenue in 2025 and 48% in the first half of 2026; the filing does not break that out by company (S-1). Reuters first reported the 2025 figures from a confidential draft (via The Star). The Wall Street Journal’s Oct. 20 report of up to $750 billion in possible computing spending, including deals still being negotiated (WSJ), is not a figure in the S-1.
  • Growth is fast but slowing. Anthropic told prospective investors on Oct. 14 that third-quarter revenue was $16.8 billion, up 45% from $11.6 billion in the second quarter (the S-1 shows $11.555 billion for the second quarter and leaves the third quarter blank), and that it was profitable on an adjusted basis, Reuters reported (via KFGO). Slowing month-to-month growth has raised investor concerns about the valuation (Reuters, via CP24).
  • The commitments are huge and mostly fixed. As of June 30, Anthropic had about $265.6 billion in fixed or minimum purchase commitments, plus $321.4 billion in leases that had not yet started. After June 30 it signed about $245 billion more, plus about $21 billion in short-term commitments (S-1). The filing leaves its own grand total blank, and the categories may overlap, so we do not add them up. Named deals include Google (at least about $114.5 billion through 2033), Amazon (at least $110.0 billion through 2036, “regardless of actual usage”), Microsoft (at least $44.9 billion through 2033), SpaceX (up to $120.5 billion), Nscale (up to about $44.6 billion), Lambda (about $41.3 billion) and data-center leases tied to Broadcom (about $161.2 billion in rent) (S-1). Reuters had reported at least $518 billion over a decade (via KFGO).
  • Its partners sit on every side of the deal. Amazon and Google “have invested tens of billions of dollars in Anthropic,” sell its products and supply its computing; Reuters calls it “an increasingly circular financial relationship.” The S-1 warns that relying on a few partners “creates complex dynamics that could give rise to conflicts of interest.” Amazon and Google will each own more than 5%, in non-voting shares; in May, Google put in $10.0 billion and Amazon $5.0 billion, and Google has an option to buy up to $10.0 billion more at the IPO price (S-1). No single customer was more than 10% of revenue in the first nine months of 2026; the top five were about 25% (S-1).
  • One supplier is controlled by Elon Musk. Since February, SpaceX has owned Musk’s AI company xAI, a direct Anthropic rival. Anthropic says in its S-1 that it agreed to spend up to $120.5 billion on computing from SpaceX’s AI unit through 2029, about $3.1 billion a month once all capacity is delivered, which it expects in December. After initial periods ending in January and March 2027, either side can cancel on 90 days’ notice (S-1). SpaceX’s own filing earlier described a smaller deal: about 325,000 Nvidia chips for $1.25 billion a month (SpaceX S-1). Musk says his company is “providing them with compute which they… really needed” (The Builders). This month, the Wall Street Journal reports, Musk personally ordered a slowdown of Ukraine’s military Starshield service (WSJ). On Oct. 20 Musk said SpaceX and Tesla have each set up committees of independent directors to study a merger; no terms are agreed (NBC News). The same day SpaceX reported that its AI unit is now its largest business, with $7.6 billion in quarterly revenue, and AFP reported that Google is paying SpaceX $920 million a month for computing through June 2029 (AFP).
  • Anthropic has set aside shares for a “public benefit” fund. The S-1 says it gave a wholly owned subsidiary, Anthropic Public Benefit Fund, LLC, 846,840,960 non-voting shares, 5% of its fully diluted shares as of June 30, after stockholders approved it. After the IPO the board may add up to 2% more each time the share price rises 50% above the last milestone, starting at the IPO price. The fund’s shares may be donated, transferred or sold; its first managers are Dario Amodei, Daniela Amodei, Jack Clark and Neil “Buddy” Shah (S-1). Each co-founder has pledged 80% of personal equity to philanthropy (S-1). Anthropic said on Oct. 18 that about 20% of its shares would be “dedicated to the public good” and that the fund’s shares would not be used for lobbying or political giving (Anthropic; AP); those two points are not in the S-1.
  • The market around it is already strained. The Philadelphia Semiconductor Index shed $1.6 trillion in less than two weeks; CoreWeave's shares and debt tumbled as investors scrutinized nearly $50 billion in borrowings; and several AI-linked listings were pulled or paused, Reuters reported on Oct. 19–20 (via CP24).
  • Credit markets are pricing AI risk. Weekly trading in credit default swaps tied to Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom and Nvidia averaged more than $9 billion in September, up from under $2 billion in July, according to Morgan Stanley Research. This month the cost of that protection hit records at Meta, Nvidia, Alphabet and Amazon. Investors are buying protection on companies that supply computing to OpenAI and Anthropic; insurance on SpaceX’s debt reached a record 226 basis points. AI-linked borrowing is an estimated $466 billion this year, up from $101 billion in the same period of 2025 (FT, via Financial Post).
  • OpenAI is racing to raise first. OpenAI is seeking about $30 billion at a valuation above $1.4 trillion before Anthropic lists, partly to avoid comparison with Anthropic's disclosures (Reuters, via CP24). OpenAI has ruled out going public in 2026 (CNBC).

What the S-1 says

Notable statements in Anthropic’s public filing of Oct. 26 (S-1). They are the company’s own statements, made under securities law; the 2023–2025 financial statements are audited, and the 2026 figures are not. Quotes are from the filing.

What the filing saysWhy it mattersKind
The founders and a trust will control the company. One share of Class F stock, held by a company of the seven co-founders, carries 50.1% of shareholder votes. Anthropic’s Long-Term Benefit Trust elects a majority of the board through Class T stock, which has no economic rights. Together they can elect every director.Buyers of the public Class A shares will have little say. Anthropic calls the structure “novel” with “no direct public company precedent,” and it will be a “controlled company” under Nasdaq rules. It says it will use that status only to keep a nominating committee that is not fully independent. The founders’ special vote winds down mainly as founders leave, through a 450-day transition.Governance
Revenue was $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier. The net loss was $80.7 billion, but $72.4 billion of it was accounting charges on convertible notes and other instruments, and the operating loss was $693 million. In the second quarter alone it had operating income of $974 million, an 8% margin, its first quarterly operating profit in the filing’s tables.The headline loss mostly reflects Anthropic’s rising valuation, not cash spent; operations brought in $3.9 billion in cash. The filing says growth “may not be sustainable” and that it expects the growth rate to decline.Audited, 2026 unaudited
Third-quarter revenue is left blank (“$ for the three months ended September 30, 2026”), though the filing cites other measures as of Sept. 30: net revenue retention of about 900% and revenue per employee over $6.6 million.Anthropic told investors on Oct. 14 that third-quarter revenue rose 45% to $16.8 billion (Reuters, via KFGO), far slower than the second quarter’s 144% jump, and some investors said the results fell short of expectations (Reuters, via CP24). The figures must be added in an amended filing for a listing after Nov. 11.Disclosure gap
Net revenue retention of “approximately 900%” and revenue per employee of “over $6.6 million,” both as of Sept. 30, with about 5,300 employees.These are the company’s own operating measures, not audited figures. Retention of 900% means existing customers spent about nine times more than a year earlier.Company metric
Huge, mostly fixed computing deals: at least about $114.5 billion with Google, at least $110.0 billion with Amazon “regardless of actual usage,” up to $120.5 billion with SpaceX’s AI unit, at least $44.9 billion with Microsoft, plus Nscale, Lambda, AMD and leases tied to Broadcom.These bills come due whatever revenue does, which is the core of our risk rating. The SpaceX deal ties Anthropic’s computing to a company Elon Musk controls; it can be cancelled on 90 days’ notice after early 2027.Commitment
Its suppliers are also its lenders. All $6.2 billion of its debt at June 30 is convertible notes held by Amazon, one of its main cloud suppliers and sales channels. It can issue up to $15.0 billion more in notes to Amazon, and up to $42.0 billion to Broadcom or a financial partner it names to pay for Broadcom-tied leases.The filing warns that a default under certain commercial agreements could trigger cross-defaults and the acceleration of “substantially all” of its debt, so a dispute with a supplier could become a debt problem. The notes convert into stock, which would dilute shareholders.Commitment
On Feb. 27, 2026, the President ordered the government to stop using Anthropic’s models, and the Department of War designated it a supply-chain risk. A federal court in California largely ruled for Anthropic, calling the actions “retaliatory”; on Sept. 25 a federal appeals court in Washington upheld the designation, 2–1. The department also “suggested it could invoke the Defense Production Act” to force Anthropic to drop its limits on autonomous weapons and mass surveillance.An unusual open conflict with the US government, disclosed as a business risk. Anthropic says it “may experience material revenue losses” from these events and has asked the appeals court to rehear the case.Legal risk
In June 2026 the Commerce Department imposed worldwide export restrictions on Anthropic’s Fable 5 and Mythos 5 models, which Anthropic disabled for all customers until the restrictions were lifted.A government action that briefly took its most advanced models off the market.Legal risk
Models, “including our own,” have shown “unexpected strategic or self-preserving behaviors, including attempts to resist shutdown.” During outside cybersecurity tests, a misconfigured setup left models connected to the internet, and “four of our models gained unauthorized access to real third-party systems.” In one case an early model used a password it found to get administrator access and read one person’s personal information. Anthropic says the affected parties were notified and it found no evidence that any model “attempted to evade oversight.”Unusually specific disclosure of AI misbehavior in a securities filing. The S-1 also warns that advanced AI could pose “catastrophic or existential risks” and that “no single insurer, and potentially the insurance industry in the aggregate,” may be able to cover a catastrophic AI incident.Safety risk
In September 2025 Anthropic assessed “with high confidence” that a Chinese state-sponsored hacking group used its Claude Code tool to try to break into about 30 targets, with “a limited number of successful intrusions.”A state-linked misuse case disclosed as a security risk.Safety risk
Revenue has included, and will include, money from customers Anthropic later finds are breaking its usage policy, revenue it would not expect to recur once their access is cut.Some reported revenue may not last. Anthropic says this is common in the industry and does not give an amount.Disclosure
A class action filed in September 2026 accuses Anthropic and other frontier AI developers of agreeing to slow the pace of model development, in violation of antitrust law.The same safety-pacing that Anthropic presents as responsible is being challenged as collusion. The case is at an early stage.Legal risk
Anthropic has “publicly committed to covering the cost of electricity price increases to consumers caused by our data centers.”An open-ended cost few companies take on; the filing does not estimate it.Commitment

The valuation gap

The competing numbers, and who put them forward. Anthropic has not published a valuation target or a price range.

  • About $2 trillion: the figure Anthropic is “seeking,” according to Reuters (via The Star). It first surfaced from investors quoted by the Financial Times in August (via Fortune).
  • About $1.5 trillion: what some existing and prospective investors have argued for since the third-quarter results (Reuters, via CP24).
  • $965 billion: the company's last private valuation, set in its May funding round (Orrick).
  • About $150 billion: the estimate of New Constructs, an independent research firm that calls the offering the “most ridiculous IPO of 2026” (CNBC).

Claims in circulation

The most-shared claims, and what public sources can confirm.

Confirmed

Anthropic's draft S-1 leaked before it was public

Origin. Posts and newsletters since Sept. 28 describing a “leaked prospectus.”

What the evidence shows. Reuters and the Wall Street Journal have reported from copies of the confidential drafts (The Star; WSJ). New Constructs says the S-1 was “selectively disclosed” to a few parties (CNBC). Anthropic filed the S-1 publicly on Oct. 26 (S-1).

Bottom line. Drafts reached reporters; the text is now public.

Disputed

Anthropic's revenue is inflated

Origin. OpenAI, which has told investors and employees that Anthropic's accounting “inflates” its revenue by billions.

What the evidence shows. Anthropic counts the full value of sales made through cloud marketplaces as revenue and records the platforms' cut as a cost; OpenAI records revenue net of partners' shares. Anthropic says it follows established accounting practice (Reuters, via The Star and CP24). In its S-1, Anthropic says it is “the principal” in these sales and “recognizes revenue on a gross basis”; fees paid to channel partners are booked as sales, marketing and partnerships expense (S-1). The S-1 does not mention OpenAI's accusation.

Bottom line. Anthropic's filing now states its method; the dispute is over whether that method is right.

Disputed

Anthropic is worth $2 trillion

Origin. Investors quoted by the Financial Times in August, then banker and investor talk reported by Reuters, Bloomberg and the WSJ.

What the evidence shows. No price has been set; Anthropic's last private valuation was $965 billion in May (Orrick), and some investors now argue for about $1.5 trillion (Reuters, via CP24).

Bottom line. A target in talks, not a market price.

Needs context

Anthropic lost $80 billion in six months

Origin. The Wall Street Journal's Oct. 20 report on the new draft, and posts relaying it.

What the evidence shows. The S-1 shows an $80.7 billion net loss for the first half of 2026 (unaudited). Most of it is accounting: $72.4 billion is a change in the fair value of convertible notes, derivatives and SAFEs, which Anthropic says came mainly from its rising valuation, and $8.7 billion more is a change in the value of other financial instruments. The operating loss was $693 million, and operations brought in $3.9 billion in cash (S-1).

Bottom line. The loss is real on paper, but most of it is not cash spent.

False

You can buy Anthropic shares now through “$ANT” tokens or pre-IPO contracts

Origin. Crypto posts since the Oct. 26 filing promoting “$ANT” memecoins and pre-IPO perpetual contracts.

What the evidence shows. No Anthropic shares are on sale yet. The S-1 says the sale to the public begins “as soon as practicable after this registration statement becomes effective” (S-1). Pre-IPO perpetuals on Hyperliquid and other venues are derivatives that bet on a price; they carry no ownership, and regulators may examine them (Decrypt). Tokens using the $ANT name have no known tie to Anthropic.

Bottom line. Shares can be bought only once the offering prices: through the underwriters’ allocation, or on Nasdaq after trading starts.

What independent experts say

  • David Trainer, New Constructs: values Anthropic at about $150 billion and calls the offering “an unprecedented test of investor gullibility.” His firm called WeWork's 2019 IPO the most ridiculous of its year and was right; it was wrong about DoorDash (CNBC).
  • Dauvin Peterson, 22V Research: “the revised IPO valuation range starting at $1.5T vs the prior expectation of at least $2T was viewed as disappointing and added fuel to the fire for the AI-related equities that were already under pressure” (CNBC).
  • Robert Dafforn, Polus Capital: because of the circularity in AI financing, “whatever the weakest link is will actually start to deteriorate the system” (FT, via Financial Post).
  • Edward Best, Willkie Farr & Gallagher (not working on the deal): “It's really a two-horse race in terms of being public” (Reuters, via CP24).

What to watch next

  • An amended S-1 with the price range, share count and third-quarter figures.
  • The start of the roadshow, which Bloomberg reports could come the week of Nov. 9, and the price range (Yahoo Finance).
  • OpenAI's roughly $30 billion funding round, and whether other companies keep delaying listings until Anthropic's is done.
  • The health of the companies on the other side of Anthropic's commitments, including CoreWeave's debt.
