If you have been asking when is Anthropic going to IPO, the wait is nearly over. Anthropic is expected to begin trading on the Nasdaq Global Select Market under the ticker symbol ANT during the week of November 16, 2026, according to multiple reports, with some reports pointing to a debut as soon as Thursday, November 19, or Friday, November 20. The company officially launched its IPO roadshow on Tuesday, November 10, and the final share price is expected to be set as early as Friday, November 13, after the market closes.
The maker of the Claude AI assistant has not yet confirmed an exact first day of trading, and the timing could still shift based on market conditions and final regulatory approval. But every major step in the process — from the confidential June filing to the public S-1 on October 26 to this week’s roadshow — is now complete. Here is everything U.S. investors need to know.
When Is Anthropic Going to IPO? The Full Timeline
Anthropic’s path to the public markets has moved quickly by IPO standards. The company confidentially submitted IPO paperwork to the SEC on June 1, 2026, edging out rival OpenAI in the closely watched race to become the first frontier AI lab to go public.
The key dates so far:
- June 1, 2026 — Anthropic confidentially files for a U.S. IPO
- October 26, 2026 — Anthropic publicly files its Form S-1 registration statement with the SEC
- November 10, 2026 — The company launches its investor roadshow
- November 13, 2026 — Earliest date the final IPO price can be set
- Week of November 16, 2026 — Targeted trading debut, with reports pointing to November 19 or 20
Anthropic has a strong incentive to move fast: reports indicate the company wants to complete the offering before the U.S. Thanksgiving holiday on November 26, when markets thin out and attention shifts away from new listings. You can follow every update directly through Anthropic’s official newsroom, which announced both the S-1 filing and the roadshow launch.anthropic
What the S-1 Filing Revealed
Anthropic’s public S-1, filed October 26, gave investors their first detailed look inside one of the most valuable private companies in the world. The filing was announced by Anthropic alongside its plan to list Class A common stock on the Nasdaq Global Select Market under the symbol ANT.anthropic
The headline numbers show a business growing at a pace almost never seen at this scale:
- Revenue of $33.2 billion for the first nine months of 2026 — up 1,206% year over year
- Operating loss of $1.3 billion over the same period, a major improvement from $5.2 billion in the first nine months of 2025
- $895.4 billion in total spending commitments, primarily for computing power and data center infrastructure
- $69.8 billion of those commitments due within the next 12 months
The filing also showed a massive accounting net loss of roughly $80 billion, even as underlying operating results improved — a figure that has fueled debate about how the company should be valued. Risk disclosures in the prospectus range from a narrow customer base to the possibility of runaway AI systems posing what the company itself describes as existential risks.
IPO Price Range, Shares, and Valuation
According to the terms disclosed at the roadshow launch, Anthropic is offering 825 million shares of Class A common stock at an expected price of $70.00 to $78.00 per share. The breakdown:
- 801.4 million shares sold by Anthropic itself
- 23.6 million shares sold by existing stockholders (Anthropic receives no proceeds from these)
- A 30-day underwriter option for up to 123.75 million additional shares
At the top of the range, the base offering would raise roughly $64.4 billion — stopping just short of SpaceX’s record-setting June 2026 IPO, which raised $85.7 billion at a valuation of about $1.77 trillion. Including a separate private placement, Bloomberg reports the total could approach $90.4 billion.
The price range implies a valuation that has been a moving target. Earlier in 2026, investors expected Anthropic to seek as much as $2 trillion. After a punishing post-midterm selloff in AI stocks, Reuters reports the company is now targeting a valuation of around $1 trillion, while Bloomberg and Yahoo Finance put the fully diluted figure at roughly $1.4 trillion — still enough to make it one of the largest IPOs in history.reuters
The $26 Billion Private Placement From Big Tech
One unusual feature of this deal: alongside the public offering, Anthropic is arranging an additional $26 billion private sale of non-voting Class N shares to major technology companies, including Nvidia, Microsoft, Google, TSMC, Broadcom, AMD, and Micron.
These strategic buyers will pay the same price as public investors — but unlike everyone else, they will reportedly not be subject to the standard six-month lockup that prevents insiders from selling after the debut. For retail investors, that is a detail worth watching, since these holders could have more flexibility to sell early.
How to Buy Anthropic (ANT) Stock
Anthropic stock is not available to buy yet. There are two ways to participate once it goes public:
- At the IPO price: Reports indicate a portion of shares will be reserved for retail investors through several major brokers, reportedly including Robinhood, Fidelity, and Charles Schwab, among others. Availability depends on your brokerage, and demand is expected to be extreme.
- On the open market: Most investors will simply buy ANT through any brokerage after it begins trading on Nasdaq, paying whatever the market price is — which may be sharply higher (or lower) than the IPO price.
Practical advice: if you want IPO shares, check now whether your broker offers IPO access and what eligibility requirements apply. If you plan to buy on the first trading day, remember that newly public AI stocks can be extremely volatile, and the price you pay in the first hours may look nothing like the IPO price.
Why the Valuation Came Down
The IPO arrives at a delicate moment for the AI trade. The U.S. midterm elections on November 3 were followed by a broad selloff in AI-related stocks, and political backlash against data center construction has grown. According to Yahoo Finance, prospective investors debated a valuation of roughly $1.1 trillion to $1.3 trillion before the final terms were set.finance.yahoo
There was even a final dose of drama: on November 9, a leaked prospectus briefly suggested a $69.3 billion fundraising target before Anthropic retracted it as inaccurate, calling the figure outdated.
The bigger picture matters too. Even an AI giant like Anthropic is being priced against cooler investor sentiment than at any point in the past two years — and its debut will be read as a referendum on the entire AI investment boom.
Risks Investors Should Weigh Before Buying ANT
The S-1 is candid about the risks, and so should any investor be:
- History is not kind to IPO buyers. Of more than 9,000 IPOs from 1975 to 2021, about 60% were flat or lower three years after their first-day close, according to University of Florida professor Jay Ritter.
- Index-fund buying may only help briefly. Anthropic will likely get an early boost as index funds are forced to buy it — but SpaceX fell 15% in its first week in the Nasdaq-100 despite a similar boost.
- Nearly $900 billion in commitments could pressure cash flow for years, especially with $69.8 billion due within 12 months.
- A narrow customer base and regulatory uncertainty around AI are explicitly flagged risks.
For long-term investors, the more prudent approach may be waiting for the first few earnings reports as a public company before committing capital.
What to Watch Next
Three milestones will settle the question of when exactly Anthropic goes public. First, the SEC must declare the registration statement effective — possible as early as November 13, since the SEC is closed November 11 for Veterans Day. Second, Anthropic and its underwriters will set the final price, likely the evening before trading begins. Third, the stock opens on Nasdaq under ANT — potentially as soon as Monday, November 16, with reporting pointing to November 19 or 20.
Any of these steps can slip. If market conditions deteriorate or regulatory issues arise, the offering could be delayed. But with the roadshow underway and the calendar pointing at the week before Thanksgiving, all signals point to Anthropic becoming a publicly traded company this month.
Frequently Asked Questions About the Anthropic IPO
When is Anthropic going to IPO exactly?
Anthropic has not confirmed an official first trading day, but the company launched its roadshow on November 10, 2026, and multiple reports from the Wall Street Journal and Reuters point to a Nasdaq debut during the week of November 16 — most likely Thursday, November 19, or Friday, November 20. The final date depends on the SEC declaring the filing effective and the company setting its final price, which could happen as early as November 13.
What stock exchange will Anthropic trade on, and what is the ticker symbol?
Anthropic has applied to list its Class A common stock on the Nasdaq Global Select Market under the ticker symbol ANT. Once trading begins, the stock can be bought and sold through any standard U.S. brokerage account.
How much will Anthropic stock cost?
The expected IPO price range is $70.00 to $78.00 per share. The final price will be set after the roadshow based on investor demand, and it could fall outside that range. Once trading begins, the open-market price will be determined by supply and demand, which can differ significantly from the IPO price on the first day.
How much money will Anthropic raise in the IPO?
At the top of the price range, the base offering of 825 million shares would raise roughly $64.4 billion, one of the largest IPOs in U.S. history. Including a separate private placement of non-voting shares to major technology companies, the total could approach $90 billion.
How can I buy Anthropic stock as a regular investor?
A portion of shares is expected to be offered to retail investors through several major brokers, reportedly including Robinhood, Fidelity, and Charles Schwab. Check whether your brokerage offers IPO access and what its eligibility requirements are. Otherwise, you can buy ANT on the open market through any broker once trading begins.
What will Anthropic’s valuation be after the IPO?
The price range implies a valuation of roughly $1 trillion to $1.4 trillion, depending on how it is calculated. That is below the $1.5 trillion to $2 trillion figures discussed earlier in 2026, reflecting the recent selloff in AI stocks after the midterm elections.
Is Anthropic profitable?
Not yet on a net basis. The company reported $33.2 billion in revenue for the first nine months of 2026 and sharply narrowing operating losses of $1.3 billion, but the filing also showed a large accounting net loss of roughly $80 billion, alongside nearly $900 billion in long-term spending commitments for computing infrastructure.
Is investing in the Anthropic IPO a good idea?
That depends on your risk tolerance and time horizon. Anthropic is the first frontier AI lab to go public, with extraordinary revenue growth, but it carries heavy infrastructure commitments, a narrow customer base, and a valuation that assumes years of continued AI demand. Historically, about 60% of IPOs were flat or lower three years after their first-day close — a reminder that buying on day one is a high-risk strategy.
What happens if the IPO is delayed?
The timing is not guaranteed. Market volatility, regulatory issues, or weak investor demand could push the debut past the targeted week. If the offering does not price before Thanksgiving on November 26, it could slip into December or later, since companies typically avoid launching major listings into holiday-thinned markets.
