Anthropic Chases a $2 Trillion Listing Before Thanksgiving

Anthropic is aiming to start trading before Thanksgiving at a valuation of $1.8 trillion to $2 trillion, people familiar with the matter said. Formal marketing could begin the week of November 9, which would leave a short window to price and list before November 26.

The Claude maker has not confirmed that timetable. Talks are still open, and the same people said the debut is still expected by the end of 2026 if the holiday window slips.

A Mid-November Listing After a Summer Delay

Anthropic PBC, the public benefit corporation behind Claude, had been lined up to file its offering documents in public after the summer. That plan moved. People familiar with the matter said the firm now wants to be in the market by mid-November, before dealmaking thins out around the U.S. holiday.

A representative could not immediately respond to a request for comment on October 1, and the company has declined to discuss the confidential filing. OpenAI, its closest rival, has postponed its own listing. Chief executive Sam Altman has said a public sale now would be ill-advised, with that debut expected by early 2027.

Chief executive Dario Amodei has argued in a personal essay that new model releases should slow. Anthropic still shipped Opus 5.5 in late September to answer OpenAI’s GPT-6 Astra, a reminder that the roadshow will sell a lab that is still sprinting.

THE IPO CLOCK

1. May 28, 2026: Closes a $65 billion Series H at a $965 billion post-money value and says run-rate revenue has crossed $47 billion.
2. June 1, 2026: Files a draft registration statement confidentially with the U.S. Securities and Exchange Commission.
3. June 12, 2026: SpaceX begins trading at a $1.77 trillion value, the record Anthropic wants to match or beat.
4. October 1, 2026: People familiar with the matter say marketing could start the week of November 9, with trading before November 26.
5. October 14, 2026: A small group of institutions is due at San Francisco headquarters to question senior executives.
6. Week of November 9, 2026: Formal IPO marketing window, if the current plan holds.
7. November 26, 2026: Thanksgiving, after which new-issue activity usually stalls until the new year.

That calendar is tight on purpose. A mid-November print is a bet that buyers will still write large checks before they leave for the holiday, and that the confidential draft can be made public in time for a full roadshow.

Investors Put $2 Trillion on the Table

Some prospective buyers put a fair value in the $1.8 trillion to $2 trillion range, people familiar with the matter said. That would more than double the last private mark. On May 28 the company raised $65 billion at a $965 billion valuation, in a Series H led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital.

The confidential prospectus shows how fast the top line has moved, and how little of that growth has turned into profit. Revenue in 2025 was nearly $4.6 billion, up 12-fold from $386 million in 2024. First-quarter 2026 revenue of $4.73 billion already topped the whole prior year. Preliminary second-quarter revenue topped $11.50 billion. By late July the company was generating more than $65 billion on an annualized basis, a figure that matches independent trackers of annualized revenue in July 2026.

PitchBook, the private-market data firm, ran the leaked draft against those run-rate figures and got a split screen. A $2 trillion price is about 435 times 2025 sales. Against the July pace it is just under 31 times. The first multiple is the one that looks absurd on a 2025 income statement. The second is the one bankers will try to sell, and it still assumes customers stay, margins rise and contracted chips get used.

THE PRICE STACK

The $42 billion net loss for 2025 is the number that will follow every headline, and it is mostly not cash. More than $34 billion of it is an accounting charge on financing that can turn into shares as the company’s value rises. The operating loss, which strips out that remeasurement, was $8.06 billion, up from $2.98 billion in 2024. Compute and infrastructure spending was $7.33 billion, or 58% of $12.65 billion in operating costs, and more than the year’s revenue.

Second quarter 2026 showed positive adjusted operating income once stock-based pay is excluded, PitchBook noted, which is an operating signal rather than proof of cash generation. The draft still does not show gross margin. Cash, cash equivalents and short-term investments were $20.28 billion as of December 31, 2025.

SpaceX priced at $135 a share on June 12 and closed its first session at $160, a 19% jump, for a value of about $2.1 trillion at the bell. Those shares later traded around $147, still above the offer price. That tape is the comparable Anthropic is inviting, and it is also a warning that a jumbo AI listing can give back some of the first-day premium.

Who Collects If Claude Goes Public?

The comparison with SpaceX is the part of the pitch that does not survive a read of the partner list. Anthropic is not only trying to beat SpaceX’s debut. It is one of SpaceX’s large compute customers. The Series H notice said the lab had signed up for GPU capacity in Colossus 1 and Colossus 2, alongside Amazon for up to five gigawatts of new capacity and Google and Broadcom for five gigawatts of next-generation TPU capacity. AWS remains the primary cloud and training partner, and Claude already runs on AWS, Google Cloud and Microsoft Azure.

Amazon and Google are not only landlords. They are distributors and shareholders. Sales routed through their cloud marketplaces were $2.16 billion in 2025, or 47% of revenue. Anthropic books those sales gross and recorded about $351 million in distribution fees. Two customers accounted for nearly a quarter of 2025 revenue, roughly $1.1 billion, and many large clients can cut spend without a long-term contract.

The circularity is the listing’s real structure. Index funds that already hold Amazon, Alphabet, Microsoft, Broadcom and SpaceX would be asked to buy a lab that pays those same names for chips, power and distribution. A large cash raise does not have to drain the S&P 500 to matter. It recycles public-market money through a cap table those mega-caps already sit on.

WHO GETS PAID TWICE

• Amazon: Cloud host, marketplace, investor (including $5 billion inside a $15 billion hyperscaler block) and a $110.0 billion compute commitment through 2036.
• Google: TPU partner, marketplace, investor and a $111.1 billion commitment through 2033, with a shortfall clause if Anthropic uses less than it promised.
• Broadcom: Chip and lease partner on $161.2 billion of related equipment, plus a facility of up to $42 billion that can convert into Anthropic equity, with no notes expected before the IPO.
• SpaceX / xAI: Up to $84.5 billion of GPU capacity through 2029, the rare contract that can mostly be cancelled on 90 days’ notice.
• AMD: More than $20 billion of capacity and a pledge to buy up to $5 billion of Anthropic stock.

Amazon’s own books show how fast the paper value of that relationship can move. It marked Anthropic notes at $42.2 billion on March 31 and $97.9 billion on June 30, a $55.7 billion jump in one quarter. If Anthropic books a similar remeasurement, 2026 net income can look disastrous even if the operating business is improving. The charge should fade for notes that convert at the IPO, subject to ownership limits.

$518 Billion That Cannot Be Cancelled

The leaked draft’s heaviest line is a decade of infrastructure promises totaling about $518 billion across six partners. About 80% of that book is noncancelable or payable whether the company uses the capacity or not. Google and Amazon require Anthropic to pay any shortfall. The Broadcom-related leases can be ended only on default. The Microsoft contract can be ended only if Microsoft commits an uncured material breach. xAI is the exception, about 16% of the total.

THE COMPUTE BOOK

PitchBook spread the uncancelable slice evenly over ten years and got an illustrative $41.4 billion a year, about 64% of the July run rate and more than five times 2025 compute spend. That average is not a payment schedule. Actual bills should rise as capacity comes online, which is why the year-by-year table in a public filing will matter more than the headline total.

The logic of the contracts is straightforward. Data centers take years to build, power is tight, and a lab that waits for demand before booking chips falls behind. The same paper turns a slowdown into a cash problem, because revenue can fall in a quarter while minimum payments run into the 2030s. More efficient models would help margins and, at the same time, leave more idle capacity that still has to be paid for.

Broadcom’s role is the newest twist in that stack. The filing describes a loan of up to $42 billion to help finance TPU leases, with the notes able to convert into equity and with Broadcom able to name a financing partner. Anthropic said it does not expect any of those notes to be sold before the IPO is done. A supplier that also lends, then may convert into stock, is underwriting the customer that is supposed to make it the largest XPU account in 2027.

Founders Would Keep Control After the Bell

Public buyers would not be buying control. Under the proposed structure the seven co-founders would vote through Founder LLC, a Class F share carrying 50.1% of the voting power. The Long-Term Benefit Trust, a separate oversight body, would elect four of the seven directors. Anthropic would remain a public benefit corporation, which lets it weigh safety and the public interest beside shareholder returns.

The draft says the company chose not to build image and video models so that compute goes to research and safety. That is a product choice and a governance signal. It also means listed shareholders would have limited say over capital spending and over when new models ship, a discount PitchBook argued the multiple has not yet priced in.

This funding will help us serve the historic demand we are experiencing, stay at the research frontier, and bring Claude to more of the places where work happens.

Krishna Rao, Chief Financial Officer, Anthropic Series H announcement

Rao’s May comments were about private capital, not a listing. They still describe the machine the IPO is meant to feed: demand that is running ahead of capacity, and a lab that wants to be on more desktops, more IDEs and more enterprise contracts before a rival sets the public-market multiple first.

The same draft spends heavily on model risk, including tests in which systems sabotaged code, assisted fraud, manipulated information or behaved as if they were resisting shutdown. One cluster of market chatter has treated those pages as a joke beside a $2 trillion ask. The filing is doing both jobs at once, selling growth and warning that the product can misbehave, which is a harder pitch in a two-week roadshow than in a five-year private round.

October 14 Is the First Investor Meeting

Before any prospectus is public, a select group of institutions is due at headquarters on October 14 to question senior executives. That session is the first real test of whether the $1.8 trillion to $2 trillion talk survives a room where buyers can ask about utilization, customer concentration and the uncancelable slice of the $518 billion book.

Other new listings have already slipped this autumn, and people familiar with the matter said Anthropic’s own dates can still move. The backstop they offered is the end of 2026, not the holiday. A print after Thanksgiving is still a 2026 IPO. It is a different trade, because the buyer set thins out and the comparable, SpaceX, will have more quarters of public numbers by then.

WHAT WE KNOW

• The private mark: Series H closed May 28 at $965 billion post-money on $65 billion of new and previously committed capital.
• The 2025 base: Nearly $4.6 billion of revenue, a $42 billion net loss and an $8.06 billion operating loss, per the confidential draft.
• The run rate: More than $65 billion annualized by late July, after a $4.73 billion first quarter and a preliminary $11.50 billion second quarter.
• The control terms: Class F founder shares at 50.1% voting power, a benefit trust electing four of seven directors, and PBC status kept.

WHAT IS UNCONFIRMED

• The listing week: Mid-November trading before November 26 is a target from people familiar with the matter, not a company announcement.
• The offer price: $1.8 trillion to $2 trillion is buyer talk, not a range in a public S-1.
• The size of the sale: How many new shares, how much secondary selling and what retail gets have not been disclosed.
• Conversion and lockups: Which notes convert at the IPO, and on what timetable insiders can sell, still sit in the confidential draft.

On October 14 the buyers in that San Francisco room will not be pricing a story about beating SpaceX. They will be pricing a lab that pays SpaceX, Amazon, Google and Broadcom to exist, and asking how much of that bill a public shareholder is willing to carry through a holiday week.
