Anthropic IPO: Date, Ticker, Price, Lockup & How to Buy

Update (October 11, 2026): The public S-1 has still not appeared on EDGAR. The reported timeline has shifted twice since early September: the Wall Street Journal reported on September 18 that Anthropic was targeting a November 2026 listing, and Reuters reported on September 28 that the debut would likely come after the November 3 midterm elections rather than before them. Bloomberg reported on October 1 that marketing could begin the week of November 9. Investor discussions around a potential $2 trillion IPO valuation have been reported by the Financial Times and other outlets, though Anthropic has not confirmed this figure. None of this is company-announced or publicly filed.

Latest update, October 4, 2026. A draft of Anthropic's IPO prospectus has reached Reuters, which published financial details from it on September 28, the first time any of those numbers have been made public. Those are the first full-year figures ever attached to this company, and they are set out below. They are not a public filing. We checked the SEC's EDGAR database again on September 29, 2026 and there is still no Anthropic filer record, no public S-1, and no entry in the SEC's ticker registry, which means you cannot yet read the document Reuters read. Reuters also reported that the draft runs to 261 pages and gives about 80 of them, over a third, to the risks of the technology itself, warning of a "catastrophic or existential risk to humanity" and of models that show "self-preserving behaviors" and "resist shutdown". Anthropic remains private and has announced no official ticker, exchange, IPO price or trading date. On September 5 Reuters reported that the prospectus was no longer expected within days but in late September, that marketing would begin in mid-October at the earliest, and that the listing would be completed days before the November 3 midterm elections. Reuters cautioned that the plans, including the timing, are subject to change. None of it is company-confirmed.

The table below is the fastest way to see where this actually stands. Every row carries one of four labels, and the difference between them matters more than it sounds. Company-stated means Anthropic said it. Press-reported means journalists reported it and Anthropic has not confirmed it. SEC-filed means it sits in a document the SEC can hold the company to. Not announced means Anthropic has not said it publicly. Journalists may well have reported it, and it may well turn out to be true. We just cannot point to the company saying so. Publicly checkable means you can verify it yourself, usually on the SEC's EDGAR database.

No. As of September 4, 2026, Anthropic is a private company. Its shares are not listed on the Nasdaq, the NYSE or any other public exchange, and you cannot buy them through a standard brokerage account. Anthropic has confidentially submitted a draft registration statement, which is a step toward an IPO rather than the IPO itself. Submitted is not the same as filed: a confidential submission starts the SEC's review without becoming public, and only a public filing puts the document on the record.

A company going public moves through several stages, and only the last one produces something you can buy. Anthropic announced on June 1, 2026 that it had confidentially submitted a draft registration statement on Form S-1 to the SEC. An S-1 is the registration document a company files before selling shares to the public; it is where the financials, the share structure and the risk factors get disclosed. Submitting it confidentially means the SEC can begin reviewing while the contents stay private. Outsiders see nothing.

When the S-1 becomes public, it contains the prospectus investors can read, and that is the document that matters to you. It becomes visible on the SEC's EDGAR database, and details like the intended exchange and the ticker symbol would normally appear in it. No public version exists yet.

After that come the roadshow, the pricing, and then the first day of trading. That puts Anthropic at the start of the sequence, not the end. For a fuller walk through the mechanics, see what an IPO actually is.

Anthropic does not have an official stock ticker symbol. No announcement has been made. The company has not confirmed which exchange it intends to list on either, though Business Insider reported on September 13, 2026, citing a person familiar with the plans, that Anthropic had selected the Nasdaq. A ticker becomes public during the filing and exchange-listing process, and would be confirmed before trading begins, if the listing proceeds.

We are deliberately not going to guess at what it might be. Inventing a plausible-looking symbol for a company that has not announced one is how bad information starts circulating, and you can see the results of that further down this page.

Once trading begins, a real ticker will have a live exchange quote, availability through brokerages, and an order you can actually place. Not one of those things exists for Anthropic today.

This page is updated when that changes, and the status table above is the first thing corrected.

No. Codes such as ANTH.PVT, ANTHR.FG, ANTHRO and ANTHZZX shown by financial-data platforms are third-party or private-company identifiers. They are not Anthropic's official exchange ticker, and they do not mean Anthropic is publicly traded.

Data providers need somewhere to file a private company in a system built for public ones. So they assign it an internal reference, and because their pages are laid out for listed stocks, that reference lands in the slot where a ticker normally sits. It looks like a ticker because it is sitting in a ticker-shaped hole.

You cannot buy any of them. No order you can enter at your brokerage will fill against ANTH.PVT, because the code is a label in a database rather than a security trading on a venue.

This matters because people act on it. Someone searches for the ticker, lands on a page showing a code and a number, and concludes they have found a tradeable stock. Given what is on the screen, that conclusion is reasonable. That reading is also wrong.

Anthropic does not have a public stock price. Some financial websites display an estimated or private-market figure for Anthropic shares, but those are not prices set by trading on a public exchange.

Yahoo Finance provides the clearest example, which showed $589.01 against ANTH.PVT when this page was last checked on September 4, 2026. That figure is a Forge Price, a modeled estimate built from funding rounds, private transactions and indications of interest. Yahoo says plainly that it "is not a quotation."

So the number is not invented, and the site is not hiding anything. The figure comes from a private market calculation that ordinary investors cannot access through a normal brokerage account, and Yahoo labels it as one. But it is not a stock price. A listed share price comes from buyers and sellers transacting continuously on an exchange, and nothing like that exists for Anthropic today.

The providers do not even agree with each other, and not by a little. Around the same period, Nasdaq Private Market put Anthropic at roughly $730 a share, while Hiive showed figures above $1,300. Yahoo's Forge Price sat near $589. The spread is more than two to one on the same company on the same days. No provider here is malfunctioning. Each provider models different inputs, from different transactions, with different methods, because there is no continuous public market producing a single authoritative number.

If you searched for the Anthropic stock price and found a number, that is almost certainly what you found.

No Anthropic IPO date has been confirmed, and the reported timetable has already moved once. Reuters reported on August 27, 2026, citing The Information, that the prospectus would be made public after Labor Day with a potential listing in late September or early October. On September 5 Reuters reported that the prospectus was not expected until late September, that marketing would begin in mid-October at the earliest, and that the listing would be completed days before the November 3 midterm elections. Treat that as a reported timetable rather than a date announced by Anthropic, and note that it has already slipped once. It has now slipped past its own window, and the reported direction has reversed. Reuters reported on September 28 that the debut would likely come after the November 3 midterm elections. When we checked EDGAR on October 11, 2026 there was still no Anthropic filer record and no public S-1.

No IPO date has been published. Its own Series H announcement in May does not mention an IPO, a listing window, or any month. What exists is reporting, attributed to people familiar with the process, relayed by Reuters from The Information.

Even a well-sourced timetable is not a date. IPO timing depends on SEC review finishing, on market conditions holding, and on the company deciding demand is there. Any of those can move it. Companies have delayed listings by weeks over a bad market stretch and by months over a review question.

There is a reason so much on this page is reported rather than stated by Anthropic. Securities rules make companies especially cautious about IPO-related publicity at this stage. Ordinary business communications can continue, but statements that could be viewed as promoting the offering are more constrained.

One mechanical rule gives you something concrete to watch. A company using the SEC's confidential review process has to confirm it will publicly file the registration statement at least 15 days before any roadshow. The roadshow comes before pricing and the first trade. If a listing really is happening in late September or early October, the public filing cannot be far away.

It might not happen at all. Companies withdraw, postpone, or change route. This page assumes a conventional underwritten IPO throughout, because that is what has been reported, but a direct listing uses the same S-1 and has no offer price and no allocation at all.

The sequence itself is fixed even when the calendar is not. A confidential draft goes to the SEC, then a public filing appears, then the roadshow, then pricing, then the first trade. Only the first step is complete. You can watch for the second one on the SEC's EDGAR database, and that is the moment most of the unknowns on this page start getting answers.

For a sense of how the last stages actually play out, how the SpaceX debut actually traded walks through a comparable listing from pricing through the first close.

No IPO price, price range, or share count has been announced. Those numbers are set late in the process, usually the night before trading begins.

The first real price signal arrives earlier, though: an amended public filing carries an indicative price range, weeks ahead of pricing night, and that range is often revised up or down before the final number is set. That range is the number you would actually encounter first. Its most recent company-stated valuation is $965 billion post-money, but that came from a private funding round rather than from an IPO.

Two completely unrelated $65 billion figures are circulating. One is the Series H raise. The other is the reported revenue run-rate at the end of July. They have nothing to do with each other, and seeing them in the same article is not a sign that either is wrong.

The $65 billion figure you have seen is not the IPO raise. That was the Series H, a private funding round Anthropic announced on May 28, 2026, which valued the company at $965 billion post-money. Money raised in a private round comes from a named group of investors. An IPO is different: it can include newly issued shares that raise money for the company and, in some offerings, shares sold by existing holders. Either way, Anthropic has not published those numbers.

Three different numbers get blended together constantly.

You cannot buy Anthropic stock through a normal brokerage today because it is not listed. Once it lists, buying it works like buying any other listed share. Some brokerages run IPO participation programs that occasionally allocate shares at the offer price, but access is limited and never guaranteed.

There are two routes to ending up with shares on day one, and they are not equally available.

An allocation at the offer price is one route. This is the route institutions take, and a slice of it sometimes reaches retail customers through brokerage participation programs. Eligibility rules vary by broker, allocations are rationed when demand is high, and requesting shares is not the same as receiving them.

Buying on the open market once trading has started is the other. Anyone with a brokerage account can do this, and it is how most individual investors actually end up holding a newly listed stock. You pay whatever the market is asking at that moment, which is often not the offer price. That gap is covered in detail further down.

Reuters, citing The Information, reported that Anthropic is considering allowing existing shareholders to sell shares as part of the IPO. Reuters reported that this would set Anthropic apart from the SpaceX and Cerebras listings earlier this year, in which existing stockholders did not sell. If it holds, it means some of the shares changing hands would be coming from existing holders rather than newly issued by the company. Again: reported, not filed.

You cannot buy Anthropic shares through a normal brokerage account before its IPO. Some accredited or institutional investors may be able to take part in board-approved private transactions, but Anthropic says transfers made without that approval are void and will not be recognized on its books.

That is Anthropic's own language, not a cautious paraphrase. The generic explanation you will find elsewhere is that accredited investors can buy pre-IPO shares on private marketplaces. As a general statement about private companies, that holds. As a description of Anthropic specifically it falls down badly.

Anthropic's published guidance warns about unauthorized sales of its stock. Its position is that transfer restrictions in its bylaws apply to both preferred and common stock, that any transfer without board approval is void rather than merely disputed, and that it does not permit special purpose vehicles to hold its shares. Where a transfer into such a vehicle lacked approval, the company's position is that the whole chain fails. It also publishes a short list of firms it says are not authorized to buy or sell its shares.

We are describing the mechanism here, not pointing you toward it. Void is a strong word and it is the right one to notice. A buyer in that position is not a shareholder in a dispute; on the company's account they are not a shareholder at all. A marketplace can show you a listing on a company this restricted. Whether Anthropic will acknowledge the transfer is a separate matter.

For the wider picture, the wider 2026 AI IPO wave covers the whole group.

There is no Claude stock. Claude is a product, not a company. Anthropic makes it, and Anthropic is privately held, so no Claude ticker exists and there is no way to invest in Claude directly.

Plenty of people know the product long before they know the company behind it, which is exactly how you end up searching for a Claude ticker. The same pattern shows up with any product that becomes better known than its maker.

So searches for Claude stock, Claude ticker, or how to invest in Claude are all really searches for Anthropic, and the answer is the one on the rest of this page. Anthropic is private, and nothing trades on an exchange today.

Several large listed companies have invested in Anthropic, and it is tempting to treat buying one of those as a way of owning a slice of Anthropic. That approach has a flaw. When you buy shares in a large public company, you are buying that company's entire business, of which an Anthropic stake may be a very small part. Its share price will be driven overwhelmingly by everything else that company does.

If the mechanics of how ownership and share prices actually work are new to you, how share prices and valuation work starts from the beginning.

Anthropic's $965 billion valuation is a post-money figure from its Series H funding round, which the company announced on May 28, 2026 and which raised $65 billion. It reflects what a group of private investors agreed to pay for a slice of the company. Not a market price, and not what the company would be worth on an exchange.

Post-money is simpler than the word suggests. Work it backwards. If investors put in $65 billion and the agreed post-money valuation is $965 billion, then everything that existed before the money arrived was valued at $900 billion. That earlier figure is the pre-money valuation. The post-money number is broadly the pre-money number plus the cash that came in. That arithmetic assumes the whole raise bought newly issued shares; rounds this size often include tranches, employee share sales or option-pool changes, any of which make the clean subtraction approximate.

A post-money valuation describes the company and the check at the same time. Raise more money at the same pre-money value and the post-money number climbs, without anything about the business having changed that morning.

The Series H was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, alongside a long list of other institutions. It followed the Series G in February 2026, which raised $30 billion at a $380 billion post-money valuation.

The revenue line underneath those rounds is where company-stated and press-reported figures sit side by side. Anthropic said its run-rate revenue reached $14 billion at the time of the Series G in February, and that it had crossed $47 billion by the Series H in May. In August, Axios reported that the figure had passed $65 billion by the end of July, based on an update Anthropic shared with investors. That last number is reported rather than announced, and none of the three has appeared in an audited filing.

Run-rate revenue takes a recent short period and multiplies it out to a year. Run-rate is real revenue from a short period, annualized, not revenue actually earned over twelve months.

Reuters put numbers to this on September 28, 2026, from a prospectus it had seen. These are the first full-year numbers attached to Anthropic. They are reported rather than publicly filed, so you cannot check them against a document yourself yet. The reported 2025 revenue is nearly $4.6 billion, a twelvefold increase on the year, set against a net loss of about $42 billion. Roughly $34 billion of that loss was an accounting charge for the rising estimated value of financing that can later convert into shares, rather than cash spent running the business, which leaves an operating loss of more than $8 billion. Compute and infrastructure took $7.33 billion, about three times the 2024 figure and more than half of $12.65 billion in total operating expenses. Cash and short-term investments stood at $20.28 billion on December 31. Reuters also reported roughly $518 billion of future cloud and computing commitments, and that close to a quarter of 2025 revenue came from two customers who are not tied to long-term contracts.

Now put the $4.6 billion next to the $65 billion, because that gap is where people will get lost. The two measure different things. The $4.6 billion is revenue actually earned across the whole of 2025. The $65 billion is a run-rate, which is one recent period multiplied out to a year. A company growing this fast can report both honestly, and neither one is the other. When an audited filing finally appears, the annual figure is the one that will be in it.

Two figures that look contradictory are not. Anthropic's preliminary second-quarter revenue was reported above $11.5 billion for three months, while the run-rate at the end of July was reported above $65 billion. Both can hold at once: a quarter counts what was booked over three months, and a run-rate multiplies out the most recent stretch, so a fast-growing company's run-rate always runs ahead of what it has actually banked. The arithmetic is just multiplication: any company running at roughly $5.4 billion in its latest month would show a $65 billion run-rate, whatever it booked in the quarter before.

Comparisons between the AI labs deserve one more caveat. Anthropic and its rivals are reported to count cloud-partner revenue differently. Anthropic is reported to book the full value of Claude sold through partners such as Amazon Bedrock and Google Cloud, treating the partner's cut as a cost. OpenAI is reported to book only its own share. The difference in approach has been publicly debated between the two companies. Headline run-rate figures across the two companies may therefore not be directly comparable, and the public filing should make Anthropic's revenue recognition much clearer.

A negotiated private valuation and a public market price are different kinds of number. A private round is one agreement, struck once, between parties who chose each other. A market price is continuous, made by anyone who wants to trade, and it moves daily. Companies have listed above their last private valuation and companies have listed below it. We covered both sides of the wider valuation argument in whether AI valuations are a bubble.

The underlying concepts sit in how private valuations are set and market capitalization.

The IPO price is not necessarily the price most retail investors will pay. Shares are sold at the offer price to allocated buyers first. Trading then opens at whatever the market sets, which is often higher. Buying after the open means paying the market price, not the offer price.

The chain runs like this. Underwriters and the company set an offer price. Allocated buyers, mostly institutions plus whatever slice reaches retail through brokerage programs, receive shares at that price. Then trading opens, and from that second onward everyone pays whatever the market is asking.

So two people can both say they bought at the IPO and mean completely different things.

SpaceX makes the point concretely, because the numbers are recent and public. It priced at $135 a share. When trading opened the next morning the first public trade cleared at $150, and it closed the day at $160.95. Someone allocated shares paid $135. Someone who opened their brokerage app after trading started and bought paid $150 or more. Both of them would tell you they got into the SpaceX IPO.

One claim gets overstated everywhere, though: retail allocation is not zero. SpaceX originally targeted around 30 percent of its offering for retail buyers and cut it to the low 20 percent range before pricing, which CNBC reported on June 11, 2026 as institutional demand crowded retail out. Against a typical IPO's 5 to 10 percent, that is unusually generous rather than absent.

When more money wants in than there is stock to go around at the offer price, the gap opens, so the first public trade clears higher. None of that is guaranteed, though. Shares can and do open below their offer price, which is sometimes described as breaking issue, and then the arithmetic runs the other way.

The calculator below runs both cases. It opens on the real SpaceX numbers, and you can put in any pair of prices you like. On how first days behave generally, see first-day volatility and what happened on SpaceX's first day.

Nothing has been scheduled, because no listing date exists. But two different events both get called a halt, and they mean close to opposite things. Knowing which is which is the difference between reading a normal debut and thinking something has gone wrong.

A delayed open is not a halt. A newly listed stock does not begin trading at the opening bell. The exchange first runs a price-discovery auction, collecting buy and sell interest until it can strike an opening price. On a large listing that can take hours. SpaceX listed on June 12, 2026 and did not open until midday, and the first public trade cleared near $150 against a $135 IPO price. Nothing had failed. That was the auction doing its job, and we covered it in detail in the SpaceX IPO explainer.

A volatility halt is a halt. Once trading starts, a new listing is subject to the same Limit Up-Limit Down rules as every other listed stock: if the price moves outside a defined band inside a short window, trading pauses automatically for five minutes so the order book can settle. On a volatile debut both up-halts and down-halts are possible, and more than one can happen.

The distinction matters because the two carry different information. A delayed open means the opening price has not been found yet. A five-minute pause after trading has begun means the price moved faster than the band permits. Neither one is a judgement on the company. Both are ordinary on a large debut.

Anthropic has not announced which exchange it will list on, though Business Insider reported on September 13, 2026 that it had selected the Nasdaq, so the exact opening procedure is not confirmed yet either. Limit Up-Limit Down applies across US listed venues, so the five-minute pause mechanic holds regardless of where it lists.

The public filing will be the first public SEC disclosure containing audited financial statements. A registration statement of this kind typically includes audited revenue and losses, the share structure, risk factors, what the company intends to do with the money, and the intended exchange and ticker. Until it is public, most figures circulating about Anthropic are reported rather than filed.

Reported means a journalist has sourced it, often well, often from people genuinely close to the process. Filed means the company has put its name to it in a document the SEC can hold it to. Both are useful. Only one carries legal weight.

Most financial figures available today are either company-stated or reported by journalists rather than disclosed in a public SEC filing. The run-rate figures came from the company's own announcements and investor updates rather than from audited statements. The listing window came from reporting. The idea that existing shareholders may sell into the offering came from reporting. Not one of those figures has been filed.

Reuters, citing The Information, also reported that Anthropic is weighing lockup periods longer than the customary 180 days. A lockup is the window after listing during which insiders and early investors are contractually barred from selling. A longer one would mean less insider stock reaching the market early, which changes the supply picture in the months after listing. If you want the mechanics, see when insider lockups expire. The underwriters running the offering set these terms alongside the company, and the banks running the offering explains that role.

Structurally, Anthropic is a Delaware public benefit corporation, and its Long-Term Benefit Trust selects members of its board. Since April 2026, directors chosen by that trust have held a majority of board seats. A Delaware public benefit corporation's board is directed to balance the stockholders' pecuniary interests, the interests of those materially affected by the company's conduct, and the specific public benefit in its charter, rather than shareholder returns alone. That is unusual for a company approaching a listing, and the share classes and voting rights that go with it are exactly the kind of detail the public filing would spell out.

When the public filing lands, the table below is what changes.

Supporters point to Anthropic's reported revenue growth, its enterprise adoption, and how few pure-play frontier AI companies are available on public markets. Skeptics point to heavy capital requirements, profitability that has not been established in audited public financial statements, concentrated competition, and a valuation set in a private round rather than by an open market.

Both sides are working from the same short list of facts. No audited financial statements are publicly available yet. Everyone is reasoning from run-rate figures, a couple of funding rounds, and a set of impressions about the industry.

The bull argument runs roughly like this. Revenue has grown fast on the numbers available: $47 billion run-rate stated by the company in May, and over $65 billion by the end of July according to August reporting. Anthropic also disclosed preliminary second-quarter figures to prospective investors in August, reported on August 15 as revenue above $11.5 billion with positive adjusted operating income. Enterprise customers tend to stay put once they have built on something. And there are very few ways to own a frontier AI lab directly through a public market, which supporters argue creates real scarcity value.

The bear argument uses the same facts differently. Training and serving frontier models consumes enormous capital. That profitability figure is adjusted, which is not standardized accounting: the company excluded certain costs, and it decides which ones. The figures are preliminary and private rather than audited, they cover a single quarter, and long-term profitability has not been established in audited public financial statements. The competitive set includes some of the best-funded companies in the world. And the $965 billion figure was negotiated with a chosen group of investors rather than discovered by an open market, which skeptics argue makes it a weaker anchor than it looks.

The reported draft adds to that side of the ledger in an unusual way. Roughly 80 of its 261 pages go to the risks of the technology, according to Reuters on September 28, including a warning that the models could pose a "catastrophic or existential risk to humanity" and can show "self-preserving behaviors" or "resist shutdown". Risk factors are written to protect a company legally and every prospectus has them, so their presence is not a prediction. The proportion is still unusual, and it is reported from a draft rather than read in a filed document.

We are not going to hand you a verdict, and it would be worth nothing if we did. What would actually settle parts of this is the public filing, because public investors cannot yet verify those figures against an SEC filing.
