As of October 29, 2026, $965 billion is Anthropic's private valuation from the May 2026 Series H round, and press reports put the IPO valuation discussion at $1.5 trillion to $2 trillion. The final IPO valuation will be set only at pricing, when the amended S-1's price range meets investor demand.

Key Takeaways

The only valuation Anthropic has confirmed is $965 billion post-money, from the $65 billion Series H announced on May 28, 2026.
The IPO valuation is a separate number: press reports put the discussion range at $1.5 trillion to $2 trillion, and only the price range in an amended S-1 and the final pricing can settle it.
The valuation climbed from $61.5 billion in March 2025 to $183 billion, $380 billion and $965 billion in about fourteen months, each step announced by the company.
The Form S-1 of October 26, 2026 shows $141.1 billion raised since founding, a credit facility expanded to $15 billion in September 2026, and a 5% stake for the Anthropic Public Benefit Fund.
Amazon has put in about $18 billion and Google about $20 billion, both will hold more than 5% after the listing without voting rights, and the IPO size itself is not set yet.

What Is Anthropic Worth Today?

Anthropic is worth $965 billion on the last valuation the company has stated, set at the close of the Series H round on May 28, 2026.

That round raised $65 billion, was led by Altimeter, Dragoneer, Greenoaks and Sequoia, and was announced alongside a run-rate revenue figure above $47 billion.

The S-1 restates the capital raised but gives no new valuation, because a registration statement reports what investors paid, not what the next buyer will pay.

What the S-1 adds is the scale behind the number: revenue of $16.29 billion for the first half of 2026, a $974 million operating profit in the second quarter, and $131.7 billion of cash and short-term investments at June 30, 2026.

Those figures, not the headline valuation, are what IPO investors are expected to price when the roadshow runs.

From $965B Private to a $1.5T–$2T IPO

Anthropic's valuation moves from $965 billion to a reported $1.5 trillion to $2 trillion in three steps: the private round set a floor, the filing disclosed the balance sheet, and the pricing will set the public number.

The private floor is the $965 billion Series H mark, which was a negotiated price for new preferred shares on one date in May.

The balance sheet behind it, per the S-1, is $141.1 billion of capital raised since founding and $131.7 billion of cash and short-term investments on June 30, 2026, plus a revolving credit facility expanded to $15 billion in September 2026 with a maturity of September 4, 2031.

The public number is the one still missing: Yahoo Finance reported a discussion range of $1.5 trillion to $2 trillion.

The Motley Fool reported on October 29 that more recent estimates had drifted toward the lower end of that range.

Both are reports, not company statements, and the IPO valuation will equal the final price multiplied by the shares outstanding after the offering.

The IPO size, meaning the number of shares sold and the money raised, is not set yet either: the share count is blank in the S-1, and the $1 billion in its fee table is a registration-fee placeholder rather than the deal size.

Reuters reported in September that Anthropic was in talks with Nvidia about an anchor investment of up to $10 billion in the offering, as carried by The Star, but the S-1 summary names no anchor investor, so that remains a report.

Traders are already pricing the public number: Polymarket's closing market cap market puts the most probability on a first-day market value between $1.75 trillion and $2 trillion, which is an opinion with money behind it rather than a disclosure.

How the Price Range Turns Into an IPO Valuation

The IPO valuation is arithmetic on two numbers the amended S-1 will supply: the price range and the number of shares outstanding after the offering.

Multiplying the midpoint of the range by the post-offering share count gives the implied valuation that headlines will quote during the roadshow.

The roadshow can move the range up or down on demand, and the underwriters fix the final price the evening before trading, which fixes the IPO valuation.

The first-day closing market cap is a third number again: the closing price multiplied by the same share count, which is what the prediction-market brackets are betting on.

Each of those numbers can differ from the reported $1.5 trillion to $2 trillion range, and none of them exists as of October 29, 2026.

From Anthropic's private rounds to the reported IPO range; the last step is set only at pricing.

How Did Anthropic's Valuation Climb Round by Round?

Anthropic's valuation rose through five announced rounds, from an undisclosed figure in 2023 to $965 billion in 2026, and the last three each at least doubled the one before.

Series C, May 2023: $450 million raised, valuation not disclosed, led by Spark Capital.
Series E, March 2025: $3.5 billion raised at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners.
Series F, September 2, 2025: $13 billion raised at $183 billion, led by ICONIQ, per the Series F announcement.
Series G, February 12, 2026: $30 billion raised at $380 billion, led by GIC and Coatue, per the Series G announcement.
Series H, May 28, 2026: $65 billion raised at $965 billion, led by Altimeter, Dragoneer, Greenoaks and Sequoia.

The list covers only rounds Anthropic announced with a valuation; the Amazon and Google convertible notes and preferred purchases sit outside it and are covered in the ownership section below.

Over the same period the company's announced run-rate revenue rose from about $1 billion to over $47 billion, which is the growth the valuation steps were pricing.

All preferred series convert into common stock at the IPO, so the round structure disappears the day ANT trades.

Anthropic's announced post-money valuation at each priced round, per the company's own announcements.

There is no official Anthropic share price, and the S-1 gives none, because the price range will appear only in an amended filing.

The S-1 does fix the scale of the share count: Anthropic completed a 10-for-1 forward split of its Class A and Class N shares on September 17, 2026, so any per-share figure dated before that, including quotes of the Series H price per share, is ten times the equivalent current figure.

The Series H round priced preferred shares, and the price paid in that round is not the same thing as a public share price, because the preferred stock carried rights that the Class A common stock sold in the IPO will not.

Secondary-market quotes for "Anthropic shares" may refer to common, preferred or neither, and the company's investor notice treats unapproved transfers as void.

The honest per-share answer as of October 29, 2026 is that no number exists until the amended S-1 proposes a price range.

Why Employee Shares Are Worth Less Than the Headline Price

Preferred shares carry rights such as liquidation preferences that common shares lack, so private common stock has historically been valued below the preferred price of the same round.

That distinction ends at the IPO, when all preferred series convert into common.

Until then, a quoted "Anthropic share price" needs a label: which class, which date and whether the transfer was approved.

Why a Post-Money Valuation Isn't a Market Cap

A post-money valuation is a negotiated price for new preferred shares on one date, while a market cap is the traded price of common shares multiplied by the shares outstanding.

The two can diverge in either direction: preferred protections argue for a lower public price per share, while scarcity and demand on the first day argue for a higher one.

SpaceX closed its first session 19% above its offer price in June 2026, which is the direction the prediction markets are betting on for Anthropic, but a bet is not a measurement.

Anthropic will have a market cap only once ANT trades, and until then every "Anthropic market cap" figure is either the $965 billion private mark or an expectation.

Who Owns Anthropic Stock?

Anthropic's stock is owned before the IPO by Amazon, Google, Microsoft, seven co-founders, employees, the preferred-round investors and the Anthropic Public Benefit Fund, and the S-1 sets out each position.

Amazon: about $18 billion invested since 2023, made up of $8 billion of convertible notes and $10 billion of preferred stock; the notes convert at the IPO, with Amazon's post-conversion stake capped at 12%.
Google: about $20 billion of preferred stock bought in 2026, roughly $10 billion in March and $10 billion in May; a right to buy up to $10 billion more at the IPO price; and a 14.99% cap on the shares it newly acquires, set out in the note purchase agreement filed as an S-1 exhibit.
Amazon and Google after the listing: each expected to hold more than 5% of the company, and neither with voting rights.
Microsoft: also an investor, and also one of the three cloud providers with multi-year compute commitments.
Co-founders: seven, each holding roughly 232 million to 245 million Class A shares, with five of the seven selling some stock in the IPO.
Anthropic Public Benefit Fund: 5% of the fully diluted shares, held in a wholly owned subsidiary.
Series A to H investors: preferred stock that converts into common at the IPO.

Control does not follow share count: public Class A shares carry one vote each, a single Class T share held by the Long-Term Benefit Trust elects a majority of the board, and a single Class F share held by the founders' LLC carries 50.1% of the voting power, as summarized in the guide to where Anthropic's S-1 is and what's inside it.

Amazon's own 10-Q for the June 2026 quarter confirms the $8 billion of notes and the 2026 preferred purchases from its side of the ledger.

Why the Strategic Investors Matter Beyond Their Stakes

Amazon, Google and Microsoft are shareholders, and they are also Anthropic's largest suppliers and, in Amazon's and Google's case, its largest customers.

The S-1 discloses compute commitments of at least $110 billion to Amazon from May 2026 through April 2036, at least about $114.5 billion to Google from April 2026 through July 2033, and at least $44.9 billion to Microsoft from November 2026 through May 2033.

It adds a commitment of up to $120.5 billion with SpaceXAI through 2029, where either side can terminate on 90 days' notice from early 2027, and about $161.2 billion of equipment leases with Broadcom over five years.

Because the two largest customers are also the two largest strategic holders, the S-1 lists customer concentration as a risk, and a change in either relationship would move both the revenue line and the cost line at once.

For a valuation, that means the ownership table and the commitments table have to be read together: the stakes are the smaller number.

Anthropic's major shareholders and the caps on the two largest, per the S-1.

What Anthropic IPO Valuation Should You Expect?

No Anthropic IPO valuation has been set, and the price range in an amended S-1 will be the first figure to anchor one.

Multiplying that range by the shares outstanding after the offering gives the implied valuation, and the final price set the evening before trading gives the real one.

The reported $1.5 trillion to $2 trillion discussion range is the market's starting point, not the company's, and the roadshow that cannot begin before November 10, 2026 is where demand will test it.

The confirmed and expected steps between the filing and the pricing are laid out in the IPO timeline.

What Could Push the Valuation Up or Down

Four things visible today will shape where the price range lands and how the stock trades after it.

Demand split: Business Insider reported, citing Bloomberg, that 15% to 20% of the shares could be set aside for retail investors, which would change the mix of buyers on the first day; the S-1 names no percentage.
Index entry: Nasdaq moved SpaceX into the Nasdaq-100 within a month of its listing, and a deal of Anthropic's expected size may qualify the same way, which brings index buying and, afterwards, index-linked selling.
Lock-up supply: the S-1 sets a staggered release, with some insiders able to sell up to 10% from the first trading day, other holders released in steps on days 27, 48, 62 and 76, and the largest holders fully free only by the third-quarter 2027 results or day 365.
Governance discount: Class A buyers get one vote each under a founders' share with 50.1% of the vote and a trust that elects the board majority, a structure the S-1 itself lists as a risk.

None of these moves the $965 billion mark, which is history, but all of them bear on the number that replaces it.

What a Recent Mega-Listing Shows About Valuation Marks

SpaceX is the 2026 precedent: it priced its IPO at $135.00 per share on June 11, 2026, sold 638,888,888 shares including the underwriters' option for about $85.7 billion of net proceeds, and closed its first session 19% above the offer price.

Its first-day valuation was about $1.77 trillion, according to the Motley Fool, which is the record the reported Anthropic range would challenge.

The lesson for Anthropic is procedural: SpaceX's price range came in an amendment days before pricing, and its first public valuation existed only once the shares traded.

What the largest IPO of 2026 shows about how a price range becomes a market valuation.

Anthropic Pre-IPO Valuation: What Traders Are Actually Pricing

Pre-IPO products and prediction markets price Anthropic's expected valuation, not a share price, and that is the number to compare with the $965 billion private mark.

A pre-IPO valuation contract quoting 1,500 means $1.5 trillion for the whole company, and a prediction-market bracket of $1.75 trillion to $2 trillion means the same kind of whole-company number on the first day of trading.

Neither conveys shares, votes or dividends, and both can move on reports that the company never confirms.

On MEXC, the Anthropic Pre-IPO Countdown page tracks the milestones that will turn these expectations into a filed price range and then a traded price.
