Anthropic IPO: The $1 Trillion Valuation, Explained. What We Know and What to Expect

Kunkafa reads markets by asking how far a price could move, in which direction, within what duration. A company that has never traded has no price to read yet. What it has is a filing. Today Anthropic, the maker of Claude, set the terms of its listing, and the filing answers most of the questions a buyer should ask before the first trade. We read it.

1. The deal, in one table

The headline “$1.4 trillion” counts more shares: employee stock awards, options and the shares set aside for Anthropic’s public benefit fund. On that fully diluted basis, reports put the value between $1.3 and $1.45 trillion at the range. Both numbers are correct. They answer different questions: what the listed company is worth today, and what it would be worth once every promised share exists.

2. How the valuation got here

Private rounds from Anthropic’s announcements. Anthropic did not publish valuations for its rounds before 2025, so we do not chart them.

Three things stand out:

• Each step was bigger than the last. Value tripled from March to September 2025, doubled by February 2026 and more than doubled again by May.
• The listing is a small step after a giant one. Counted on today’s shares, the middle of the range is about the $965bn of May. Counted fully diluted, it is up to half higher. Either way, the jump is far smaller than in any round before it.
• The talk ran ahead of the price. In early October, Wall Street estimates reached $2 trillion, and investors expected a listing that month. Before the terms, $1.5 trillion was the figure under discussion. In election week, as AI stocks fell, buyers discussed $1.1 to $1.3 trillion, according to Bloomberg. The filed range sits at $1.3 to $1.45 trillion fully diluted, and $0.92 to $1.02 trillion on today’s shares: up to half below the peak expectation, in about five weeks.

The two charts measure different things. The left one is money paid. The right one is talk: estimates and discussions reported in the press, which do not always say which shares they count. Expectations rose faster than any price anyone paid, and fell back toward the last price that was actually paid.

3. What the money is for

The filing’s answer is broad: “general corporate purposes”, including working capital, operating costs and capital spending, “including investments in compute and infrastructure”, and hiring. Some could fund acquisitions; none is agreed. Part pays the tax due when employee stock awards settle at the listing.

Before the listing, at the end of September, Anthropic already held $146.6bn of liquidity: $95.6bn of cash, $36.3bn of short-term investments and $14.8bn of an unused credit line. Its partners have also agreed to lend up to $77.0bn more through notes, some of it convertible into shares, though some draws depend on Anthropic meeting revenue targets. One of those facilities, $42bn, carries 9% interest.

So the listing does not rescue a company short of cash. It adds about $85bn to a company that already holds about $147bn, because what it has promised to spend is much larger than both.

4. The $900 billion promise

This is the number to read twice. As of September and since, Anthropic has signed purchase commitments and leases worth about $900.9 billion, almost all for compute and data centres:

• About $70.7bn falls due in the twelve months after September.
• About $451.6bn before the end of 2030.
• Most of the rest between 2031 and 2045.

Set against revenue running at $81bn a year, the commitments equal about eleven years of today’s revenue. The filing says the risk plainly: Anthropic’s revenue is mostly paid by usage and “not subject to long-term contractual commitments”, while its compute contracts run for years. If demand slowed, the bills would not.

This is the same shape we described in our AI bubble investigation and in Blue Wave and AI Stocks: long, fixed commitments paid for by revenue that has to keep growing. The difference is scale, and that Anthropic now pays most of it with revenue and equity rather than debt.

5. Revenue and margins, quarter by quarter

The filing shows seven quarters of results. This is where the valuation is earned or not.

Source: Anthropic’s S-1/A, quarterly results of operations (unaudited).

What the quarters show:

• Revenue rose 45 times in six quarters, from $0.38bn to $16.96bn, and grew in every one of them. Customers paying $100,000 a year or more went from about 400 to more than 11,900.
• Compute is the business’s main cost, and it is mostly fixed. Anthropic buys compute 12 to 18 months before it arrives. While revenue outran the deliveries, compute fell from 251% of revenue to 48%. When a large delivery arrived in the September quarter, it rose back to 58%.
• One quarter of operating profit so far. The June quarter made +8%. The September quarter slipped to −3%, for two reasons the filing names: $5.0bn of short-term compute bought at a higher price to meet demand, and a $2.0bn non-cash charge for a donation-matching programme. Without that non-cash charge, the quarter would have shown an operating profit of about $1.4bn, by Kunkafa’s arithmetic.
• Prices are falling. New model versions and contract discounts cut about $600m from September-quarter revenue. Usage grew faster than prices fell.
• The net loss is mostly paper. The net loss was $23.3bn in the September quarter and $104.0bn in nine months, but $94.3bn of the nine-month figure is the rising value of convertible notes and similar securities as Anthropic’s own value rose. It is not cash spent.
• Cash. Operations brought in $6.6bn in nine months. Investment in compute and other assets took $36.5bn. Funding raised brought in $110.7bn.

The business is close to paying its running costs. It is not close to paying for its build-out from revenue alone, and its margin moves with every delivery of compute it has already ordered. That is the gap the listing funds.

6. Who pays Anthropic

• No single customer above 10%. The five largest customers brought in about 25% of revenue in the first nine months of 2026. In the September quarter, 79% came from everyone else, up from 64% in March.
• The clouds sell a large share. 44% of revenue in the nine months came through the marketplaces of cloud providers, which bill the customer and pass the money on after their fees. Amazon, Google and Microsoft are therefore Anthropic’s suppliers, its shareholders and one of its largest sales channels at once.
• Revenue depends on new models. Models released in the six months to September brought in more than 80% of the September quarter’s revenue. Staying at the front is not optional: last year’s model sells for less, and new versions cut prices.
• Most of it can stop quickly. Many of the largest customers have no long-term contract, the filing says, and can reduce or stop spending at any time.

7. Price against revenue

A valuation means little without the revenue behind it. Two ways to measure, both from the filing:

Kunkafa’s arithmetic. Twelve-month revenue is the December 2025 quarter plus the first nine months of 2026.

For comparison, SpaceX listed in June at $1.77 trillion against $18.7bn of revenue in 2025: about 95 times (Wikipedia, CBS). On that measure Anthropic is priced lower against its sales, but the run-rate figure only holds if October’s pace holds. The difference between 12.6 times and 41 times is the whole bet: whether today’s revenue rate is a step on the way up or a peak.

8. The shares still to come

The gap between $1.02 trillion and $1.4 trillion is shares that do not exist yet but have been promised. Three sources:

• Employee stock. Stock-based pay was $3.3bn in the nine months. When restricted stock units settle at the listing, Anthropic expects a one-time charge of about $14.2bn, and part of the listing money pays the tax due on them.
• The public benefit fund. Anthropic has committed 5% of its shares to a charitable fund, plus 2% more for every 50% rise in value above a baseline, subject to a shareholder vote.
• Notes that turn into shares. Partners can lend up to $77.0bn through notes, some convertible into shares at 90% of the recent market price. A lender who converts gets shares at a 10% discount.

The founders’ and employees’ special voting shares carry no economic rights, so they do not dilute the value of a share.

Each of these adds shares, so each share’s claim on future profit gets smaller. On the filing’s own range, the fully diluted value is about 40% above the value of today’s shares.

9. Who controls it

Buyers of ANT get economic ownership with limited control:

• Founders. A single Class F share, held by the seven co-founders together, carries 50.1% of the votes on ordinary matters. Class A, the listed shares, carries at most 49.9%.
• The trust. Anthropic’s Long-Term Benefit Trust holds a Class T share that elects the majority of the board.
• The suppliers. The $26bn placement buys Class N shares, which carry no vote.
• The purpose. Anthropic is a public benefit corporation. Its board must weigh shareholders’ returns against its stated purpose, the responsible development of advanced AI.

10. The suppliers who are also buyers

Google and NVIDIA put in $10bn each, AMD $2.5bn, Broadcom, Micron and Microsoft $1bn each and TSMC $0.5bn. Most of them sell Anthropic the chips, cloud or memory its commitments pay for. Money flows from supplier to customer as equity and back to the supplier as revenue. That is not unusual in this industry, but it means part of the demand behind the $900bn of commitments is funded by the companies it is owed to.

11. When the other 94% can sell

Only 825 million shares, about 6% of the 13.09 billion outstanding after the listing, can trade on the first day. The rest is locked up by agreement with the banks:

Source: Anthropic’s S-1/A, “Shares eligible for future sale” and “Underwriting”. Dates assume pricing around 18 November 2026; the filing allows exceptions.

A small float with heavy demand tends to push a first-day price up, because few shares are for sale. The same arithmetic runs the other way on unlock days, when the number of shares that can be sold multiplies. Those two dates in 2027 matter as much as the first day.

12. The first day, week and month: what SpaceX shows

How a listing trades depends on demand, and demand is not known yet. Orders close around 18 November, with trading expected on 19 November. CNBC reported, citing people familiar with the deal, that the order book was already covered at the range (CNBC). How many times over is not reported.

The nearest reference is SpaceX, the largest listing before this one:

Sources: CBS, CNBC, Leverage Shares, Motley Fool. SpaceX floated about 5% of its shares, close to Anthropic’s 6%.

And the long record: across 9,343 US listings from 1980 to 2025, the average first-day gain was 19% and the median 7% (Jay Ritter, University of Florida).

These are what happened to others, not Kunkafa’s confidence about Anthropic. They frame three cases:

• A strong book, many times covered. A small float meets heavy demand. SpaceX’s path is the example: a first-day gain near the average, a bigger peak within days, and then a slide back to the offer price within five weeks.
• A book covered once or twice. The banks price inside the range and support the price. History’s median, a single-digit first day, is the reference.
• A weak book. The price is cut below $70 or the shares trade under the offer. Nothing in the reporting so far points this way, but the market described in the next section is the one in which it happens.

In each case, the first month says little about the first year. The dates that move the most shares are the unlocks in 2027.

13. The market then and now

SpaceX listed in June, while the Nasdaq was still climbing toward the record it set on 6 October. Anthropic lists into a different market:

• Stocks are in a correction. The Nasdaq 100 closed more than 10% below its record on 2 November, the technical line for a correction. Even after a 3.4% rebound on 9 November it stood about 10.6% below the high. A bear market is a 20% fall; that line has not been crossed.
• Rates are going up, not down. The Fed raised rates in September and held in October, when two of its members voted for another rise. Governor Christopher Waller backs a December rise and says a half-point should be considered if inflation runs hot; Dallas Fed President Lorie Logan expects two more quarter-point rises, according to CNBC. October’s consumer prices rose 0.4% in the month, above forecasts, and futures put the odds of a December rise at about 85% for a quarter-point and 15% for a half-point (CBS, CME FedWatch).
• AI is the thing being questioned. The midterms put data centres on the ballot, and AI and chip stocks fell hardest. We covered that week in Blue Wave and AI Stocks. Anthropic’s $900bn of compute commitments sit at the centre of that question.

A first day in a rising market is lifted by the market; a first day in a correction has to be lifted by the company alone. That is why SpaceX’s path is a reference, not a forecast.

14. The other side

• Revenue is real and rising fast. It grew in every quarter in the filing, and run-rate revenue rose $10bn in October alone, to about $81bn.
• Operations already bring in cash. $6.6bn in nine months is rare for a company this young at this scale.
• The range is cautious. Pricing near the May round leaves room in both directions on the first day.
• Liquidity is large. About $230bn after the listing, before partner loans.

15. What Kunkafa’s record shows on the markets around it

Kunkafa does not cover Anthropic, which has no price yet, and does not invent a number for it. Kunkafa does cover the markets the listing touches: the Nasdaq 100, where ANT would list, and four of the companies buying shares in the placement. These are the forecasts Kunkafa published from 2 to 8 November at Kunkafa’s confidence of 95% and above whose duration had ended by 9 November, each measured by how far price travelled toward its level within its own duration.

100% means price reached the level. It is a distance, not an investment return. The forecasts that fell short are in the same rows. Each market’s name opens its weekly report, and how to read forecast results explains each band.

16. Where Kunkafa stops

Kunkafa does not value companies, price listings or forecast first-day trading, and nothing here is a view on whether to buy ANT. For the markets Kunkafa covers, Kunkafa answers one question: how far could this market move, in which direction, and how confident is Kunkafa about each outcome, across every duration at once.

17. Nine questions before the first trade

1. Which value is quoted? $1 trillion counts today’s shares; $1.4 trillion counts every promised share.
2. What is due in the next year? $70.7bn of commitments, against revenue running at $81bn.
3. Does the margin hold when new compute arrives? It went from +8% to −3% in one quarter.
4. Is revenue contracted? Mostly not: it follows usage.
5. Who is buying, and why? Seven suppliers are putting in $26bn.
6. What do the votes buy? Listed shares carry at most 49.9% of the votes.
7. When can the other 94% sell? Mid-May 2027 and November 2027 are the dates to mark.
8. Is the market lifting the listing, or the company? SpaceX listed into a rising market; Anthropic lists into a correction and a rate-rise cycle.
9. What does the other direction look like? A listing priced near its last private round can move either way. Both outcomes stay possible.

Listings are argued in headlines. Moves can be measured. Create a Kunkafa account and read the Nasdaq 100, NVIDIA, Microsoft and Alphabet in both directions, beside their record.
