Anthropic IPO: Date, Stock Price, Valuation and How to Buy ANT Shares

The Anthropic IPO is coming soon, but it has not happened yet. Anthropic made its S-1 public on October 26, 2026. It plans to list on the Nasdaq under the ticker ANT. Reports point to a first trading day before Thanksgiving (November 26, 2026), at a valuation of about $1.5 trillion to $2 trillion.

So Anthropic stock cannot be bought on any exchange today. That changes soon.

This guide covers everything you need to know about the Anthropic IPO. You will find the expected Anthropic IPO date, the likely price, the valuation story, the key numbers from the prospectus and the steps to buy Anthropic stock in the US. We also compare it with the OpenAI IPO, because many readers are watching both.

Key takeaways

• Status: Anthropic is not publicly traded yet. The public S-1 was filed on October 26, 2026.
• Ticker: ANT, on the Nasdaq Global Select Market.
• Anthropic IPO date: Not confirmed. Reports point to the week of November 23, with a roadshow from about November 9.
• Anthropic IPO valuation: $1.5 trillion to $2 trillion is under discussion. The last private round valued the company at $965 billion.
• Anthropic IPO price: No price range has been set. An S-1 footnote implies about $71 per share as of September 30.
• Anthropic revenue: $16.3 billion in the first half of 2026, up from $4.6 billion in all of 2025.
  

Is Anthropic going public?

Yes. Anthropic is going public, and the process is now official. The company filed a public S-1 with the US Securities and Exchange Commission (SEC) on October 26, 2026. An S-1 is the document a company must file before it sells shares to the public.

The road was long. Anthropic first filed a confidential draft S-1 on June 1, 2026. Early reports talked about a September or October listing. In September, the debut moved to November so investors could see a full third quarter of results. Then, on October 14, Anthropic held a private investor day at its San Francisco office.

Now the public filing is out. That is the clearest sign yet that the Anthropic IPO will happen in 2026. So, is Anthropic going public this year? Every sign says yes.

Is Anthropic publicly traded right now?

No. Anthropic is not publicly traded as of October 28, 2026. It is still a private company. There is no live Anthropic stock price on the Nasdaq, the NYSE or any other exchange.

Be careful with websites that show an “Anthropic stock price” today. Those numbers come from private markets or estimates. They are not real exchange prices.

When will Anthropic go public?

Anthropic will go public when its shares start trading on the Nasdaq. Reports say that should happen before Thanksgiving 2026. Year-end is the fallback. The company itself has not confirmed a date.

What is Anthropic?

Anthropic is an AI safety and research company based in San Francisco. It builds Claude, a family of large language models used by businesses, developers and everyday users. Anthropic was founded in 2021 and is set up as a Delaware public benefit corporation (PBC).

A PBC must weigh a stated public benefit alongside profit. For Anthropic, that benefit is the safe development of AI. This matters for investors, as you will see later.

Anthropic Claude AI: what the company sells

If you ask what is Anthropic in practical terms, the answer is Claude. Most of the money comes from Anthropic Claude AI products. Businesses pay to use Claude through an API. Teams pay for Claude subscriptions. Developers use Claude Code to write software. Claude is also sold through Amazon Web Services, Google Cloud and Microsoft Azure.

Business customers are the core. As of September 30, 2026, more than 1,900 customers had paid Anthropic $1 million or more over the past year. About 250 had paid $10 million or more.

Is there a Claude AI stock?

There is no separate Claude AI stock. Claude is a product, not a company. If you want Claude AI stock, you need Anthropic stock. Once the Anthropic IPO is complete, that means buying ANT shares.

Anthropic founders

Anthropic has seven co-founders. Most of them worked at OpenAI before 2021.

• Dario Amodei: chief executive officer (CEO)
• Daniela Amodei: president
• Jared Kaplan: chief science officer
• Jack Clark: co-founder and policy lead
• Tom Brown: co-founder, lead author of the GPT-3 paper
• Chris Olah: co-founder, known for AI interpretability research
• Sam McCandlish: co-founder

The Anthropic founders left OpenAI because they wanted to put safety research at the center of AI building. That mission still shapes how the company is run.

Who is Dario Amodei?

Dario Amodei is one of the Anthropic founders and the company’s CEO. He holds a PhD in physics from Princeton University. Before Anthropic, Dario Amodei was vice president of research at OpenAI. He also worked at Google Brain and Baidu.

Dario Amodei is one of the best-known voices on AI risk. He often writes about both the promise and the dangers of powerful AI. Reuters reported in August 2026 that he owns about 2% of Anthropic. His sister, Daniela Amodei, is the company’s president.

Who owns Anthropic?

No single owner controls Anthropic. Ownership is spread across the founders, employees and outside Anthropic investors.

• Amazon is the largest strategic investor. Fortune estimated its stake in the mid-to-high teens, in percent. Part of it is held as convertible notes that turn into shares at the IPO.
• Google (Alphabet) is the other big tech backer. Its stake has been reported at around 14%.
• The founders each hold a small slice. Dario Amodei holds about 2%.
• Venture and institutional funds hold the rest. Names include ICONIQ, Lightspeed, Fidelity, GIC, Coatue, Menlo Ventures and Spark Capital. Microsoft and Nvidia also invested in late 2025.

Ownership and control are not the same thing here. A Long-Term Benefit Trust of five independent trustees elects a majority of Anthropic’s board. So big investors like Amazon and Google do not run the company. When people ask who owns Anthropic, the honest answer is: many shareholders own it, but the trust and the founders guide it.

Not the same thing: what is the anthropic principle? Many people ask what is the anthropic principle and land on Anthropic pages by mistake. The anthropic principle is an idea from physics and philosophy. It says the universe must allow life, because we are here to observe it. Physicist Brandon Carter named it in 1973. It has nothing to do with Anthropic the company or the Anthropic IPO.

Anthropic IPO Date: When Will Anthropic Go Public?

The Anthropic IPO date is not confirmed yet. Bloomberg reported that Anthropic wants to start trading before Thanksgiving, which falls on November 26, 2026. Fortune pointed to Thanksgiving week, starting November 23. One Yahoo Finance report said trading could start as soon as November 16.

The date has moved before. First it was after Labor Day. Then October. Then before the US midterm elections. Now it is late November. So treat any Anthropic IPO date as a target, not a promise.

Anthropic IPO timeline

How the last steps work

An IPO follows a set path. Here is what happens between now and the first trade.

1. Amended S-1. Anthropic adds a price range and the number of shares on offer.
2. Roadshow. Bankers and executives pitch the stock to large investors for about one to two weeks.
3. Pricing. The final Anthropic IPO price is set the night before trading, based on demand.
4. First trading day. ANT shares open on the Nasdaq. Anyone with a brokerage account can buy.
5. Lock-up. Insiders wait before they can sell. Anthropic plans staggered unlocks over about a year, though some employees can sell on day one.

If you are waiting for the Anthropic IPO date, watch for step 1. The amended S-1 usually lands a few days before the roadshow.

Anthropic Valuation: How Much is Anthropic Worth?

Anthropic was last valued at $965 billion in its private Series H round in May 2026. For the Anthropic IPO, reports point to a valuation of $1.5 trillion to $2 trillion. Some investors told Bloomberg they see fair value at $1.8 trillion to $2 trillion.

So how much is Anthropic worth? Right now, about $965 billion on paper. After the IPO, the market decides.

Anthropic valuation history

The Anthropic valuation has grown faster than almost any company in history. It went from $61.5 billion to $965 billion in about 14 months. Each step below is a private funding round. If you are new to these terms, our guide to startup funding stages explains how companies move from pre-seed to IPO.

Anthropic IPO valuation: is it justified?

The Anthropic IPO valuation looks huge. The Anthropic valuation history shows each recent round at least doubling the one before. But revenue has grown even faster. Few companies have managed to scale a business at this speed. Anthropic said its annualized revenue passed $65 billion in July 2026. Reports say it projects about $110 billion of annualized revenue by year-end.

At a $2 trillion valuation, that is roughly 18 to 30 times annualized revenue. Fast-growing software stocks often trade in that range. Still, the multiple assumes growth stays very high for years.

The IPO raise could also break records. Reports say Anthropic may raise up to $100 billion. That would beat SpaceX’s record offering from June 2026.

One warning: the Anthropic IPO valuation is not official yet. Reported numbers have swung from $1.5 trillion to over $2 trillion in a few weeks. Wait for the price range in the amended S-1.

Anthropic IPO Price, Stock Price and Ticker

The Anthropic IPO price has not been set. The public S-1 leaves the price range blank. Anthropic will add it in an amended filing just before the roadshow.

But there are clues.

What the S-1 hints about the Anthropic IPO price

A footnote in the S-1 values shares at about $71.43 each as of September 30, 2026. Analysts worked this out from a $2 billion stock grant settled with about 28 million shares. That board value includes a discount, because the shares could not be traded yet. So the Anthropic IPO price will likely be higher.

Other private-market signals point the same way. Nasdaq Private Market showed about $85.10 per share on October 9.

Anthropic stock price prediction: simple scenarios

Here is a rough way to think about the Anthropic stock price. Take a valuation and divide it by about 16.9 billion shares, the count analysts used from the filing.

These numbers are illustrations, not a forecast. The real share count will rise when convertible notes (including Amazon’s) turn into stock. New IPO shares add more. A stock split before listing would change the per-share number completely.

Anthropic stock price on day one

The Anthropic stock price on the first day can be very different from the IPO price. Hot IPOs often jump at the open. They can also fall later. SpaceX, which listed in June 2026, traded below its IPO price for much of its first months. Keep that in mind before you chase the first-day Anthropic stock price.

Anthropic stock ticker

The Anthropic stock ticker is ANT. Anthropic plans to list Class A shares on the Nasdaq Global Select Market under that symbol. Each Class A share carries one vote.

Some websites show “ANTH.PVT” or similar codes. Those are private-market labels, not the real Anthropic stock ticker. After the Anthropic IPO, search for ANT in your brokerage app.

Anthropic Prospectus: Revenue, Profit and Risks

The Anthropic prospectus is the S-1 filed on October 26, 2026. It is the first time the company has shared full financial numbers in public. Yahoo Finance has a live summary of the filing. It is also long: about 240,000 words, according to The Irish Times.

You can read the Anthropic prospectus for free on the SEC’s EDGAR database. Search for “Anthropic PBC” and open the latest S-1. A PDF version can be printed from the same page. Avoid unofficial “Anthropic prospectus PDF” downloads from other sites.

Anthropic revenue

Anthropic revenue is growing at a rate rarely seen in business.

That is about 14 times more Anthropic revenue in the first half of 2026 than in the same half of 2025. Most of it comes from businesses and developers using Claude.

There is one risk inside these numbers. About 20% of first-half Anthropic revenue came from two large customers. Reports say Amazon and Google are its two biggest customers. Losing either one would hurt.

Is Anthropic profitable?

No, Anthropic is not profitable on a net basis. It posted a net loss of $80.7 billion in the first half of 2026. It lost $42 billion in 2025.

That headline loss looks scary. But most of it is an accounting charge, not cash. About $72.4 billion came from a rise in the value of convertible notes and similar tools. When Anthropic’s value went up, those notes became worth more on paper. Accounting rules count that as a loss.

The operating business tells a different story. Anthropic made an operating profit of $974 million in Q2 2026, its first ever. For the full first half, the operating loss shrank to $693 million. A year earlier it was $2.14 billion.

Anthropic profitability outlook

Anthropic profitability depends on one big cost: computing power. That cost drives its burn rate, which is how fast a company spends its cash. Anthropic spent about $9 billion on compute and infrastructure in the first half of 2026. That is more than the $7.3 billion it spent in all of 2025. The filing also lists very large long-term compute deals, some running to 2045. Earlier reports said Anthropic expects to break even in 2028.

So is Anthropic profitable? Not yet. But Anthropic profitability is much closer than the $80.7 billion loss suggests.

Key risks in the Anthropic prospectus

• Customer concentration: two customers drive about one-fifth of revenue.
• Compute costs: huge, long-term spending on chips and data centers.
• Regulation: new AI rules could raise costs or limit products.
• Government dispute: an ongoing conflict with the US administration over how the government can use its models.
• Catastrophic AI risk: the filing warns that insurance may not cover a major AI incident. For the bigger picture, see the advantages and disadvantages of artificial intelligence.
• Governance: the PBC structure and the Long-Term Benefit Trust limit shareholder control.

How to Buy Anthropic Stock in the US

You can buy Anthropic stock once ANT starts trading on the Nasdaq. Before that, most people cannot buy it. A few brokers may offer IPO shares to their customers at the IPO price, but space is limited.

Here is how to buy Anthropic stock, step by step.

1. Open a brokerage account. Use a US broker such as Fidelity, Charles Schwab, E*TRADE, Robinhood or SoFi. Do this now, not on IPO day.
2. Check for IPO access. Some brokers let customers request IPO shares. Morgan Stanley is a lead underwriter, so E*TRADE (owned by Morgan Stanley) is the most likely route. The S-1 says underwriters may set aside shares for online brokerage customers. Other brokers have not been named yet.
3. Request shares if offered. You usually enter how many shares you want and a max price. You may get fewer shares than you asked for, or none.
4. Or buy on the first trading day. Search for ANT and place an order. Use a limit order, not a market order. Prices can swing wildly in the first hours.
5. Decide your position size. Only invest money you can afford to lose. New IPOs are volatile.

How to invest in Anthropic before the IPO

If you are asking how to invest in Anthropic before trading starts, there are a few options. Each has limits.

• Pre-IPO platforms: Sites like Forge Global and Hiive trade private shares. But Anthropic does not allow share sales without board approval. Both platforms have said Anthropic shares are not available there.
• Big tech stocks: Amazon (AMZN) and Alphabet (GOOGL) are the biggest Anthropic investors. Nvidia (NVDA) and Microsoft (MSFT) own smaller ones. This is the easiest way to invest in Anthropic indirectly, though Anthropic is a small part of each company.
• Funds: Some closed-end funds and ETFs claim Anthropic exposure. NerdWallet flagged some of these claims as doubtful. Read each fund’s holdings report before you buy.
• Mutual funds: Morningstar has tracked mutual funds with stakes in Anthropic. Fidelity was a co-lead of the Series F round, for example.

Watch out for scams

Hot IPOs attract scams. Ignore offers of “pre-IPO Anthropic shares” from strangers, social media ads or messaging apps. Anthropic has not authorized private resales. If someone promises guaranteed profits on Anthropic stock, walk away.

Knowing how to invest in Anthropic safely matters more than getting in first.

Is the Anthropic IPO Worth Buying?

The Anthropic IPO could suit investors who believe AI demand will keep growing fast and who can handle big price swings. It is a poor fit for anyone who needs safe, steady returns. There is no right answer for everyone, so weigh both sides.

The bull case for Anthropic stock

• Fast growth. Revenue rose about 14 times year over year in the first half of 2026.
• Real business customers. More than 1,900 customers pay over $1 million a year.
• Operating profit is here. Q2 2026 showed the first operating profit.
• Strong position in enterprise AI. Claude is sold on all three major clouds.
• Scarcity. It may be the first pure-play frontier AI lab on a US exchange.

The bear case for Anthropic stock

• Rich price. A $2 trillion Anthropic IPO valuation leaves little room for error. Some analysts also warn of an AI bubble in tech stocks.
• Huge compute bills. Long-term spending commitments are massive.
• Customer concentration. Two customers bring in about 20% of revenue.
• Limited control. Public shareholders cannot easily change the board.
• Recent IPO history. SpaceX spent months below its IPO price after its June 2026 debut.
• Competition. OpenAI, Google, Meta AI and others are fighting for the same customers.
  

Our take

Anthropic stock looks like a high-growth, high-risk bet. Many investors wait a few weeks after a big IPO. That lets the first-day hype fade and the price settle. Others buy a small position on day one and add later. Whatever you choose, keep the position small compared with your whole portfolio.

Anthropic IPO vs OpenAI IPO

Anthropic will almost certainly go public before OpenAI. Anthropic has a public S-1 and a target date in November 2026. OpenAI has not set an IPO date, and CEO Sam Altman has said the OpenAI IPO will not happen in 2026.

OpenAI IPO date

There is no official OpenAI IPO date. OpenAI reportedly submitted a confidential draft S-1 in June 2026. Later, Altman said “not 2026” when asked about timing, citing safety rather than market conditions. He did not commit to 2027 either. So the earliest likely OpenAI IPO date is sometime in 2027.

Is there an OpenAI stock?

No. There is no public OpenAI stock today. OpenAI is private, just like Anthropic before its listing. Any “OpenAI stock price” you see online comes from private markets or prediction sites.

The same goes for searches for “open ai stock”. There is no open ai stock ticker yet, and no live open ai stock price. Microsoft (MSFT) owns a large stake in OpenAI, so it is the most common indirect way to get exposure.

OpenAI stock price: what is OpenAI worth?

Without a listing, there is no real OpenAI stock price. The best guide is its last private valuation. OpenAI raised $122 billion at an $852 billion valuation in March 2026. Reports say it is now seeking about $1.25 trillion in a pre-IPO round. Until it lists, any open ai stock price is only an estimate.

Side-by-side comparison

If you want an OpenAI stock, you will have to wait. If you want a listed frontier AI lab soon, the Anthropic IPO is the first chance.

What Reddit Investors are Saying About the Anthropic IPO

On Reddit, the Anthropic IPO is one of the most discussed listings of the year. Threads on r/investing, r/business and r/ClaudeAI show three common views.

• Fans of the product. Many Claude users say they want to own a piece of the tool they use every day.
• Valuation skeptics. Others call a $2 trillion price too high for a company with a large net loss.
• Wait-and-see buyers. A big group plans to wait for the first weeks of trading, citing how SpaceX traded after its IPO.

Reddit threads are opinions, not research. Use them to spot questions, then check the facts in the S-1.

What the Anthropic IPO Means for B2B and Sales Teams

The Anthropic IPO is also a signal for business buyers. About 80% of Anthropic revenue comes from enterprise customers, according to Forbes. That shows how fast companies are putting AI into daily work, from coding to customer support to sales.

For sales and marketing teams, the lesson is simple. AI is now a core business tool, not an experiment. Teams that use AI to research accounts, find verified contacts and personalize outreach move faster than teams that do not. Our guides to AI agents for business and business process automation show where to start. And if more leads are not turning into deals, read our take on lead prioritization for sales teams.
