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

As of about 5:45 AM PT / 8:45 AM ET on Tue Oct 27, 2026. Anthropic has not priced its IPO, so there is no ANT quote in this article. Everything below comes from the SEC filing, company statements or named press reports, and it can change the day Anthropic files an amended S-1.

Anthropic's S-1 is public, but it leaves the IPO date, share count and price range blank. Here is what is filed, what is only reported, and how regular investors could get ANT shares.

Anthropic filed its public S-1 on Monday, Oct 26, and searches for the Anthropic IPO date, the Anthropic stock symbol and how to buy Anthropic stock jumped with it. The filing answers some of those questions and leaves the biggest ones blank. For how markets reacted on filing day, see our Monday midday recap.

1. The short answer: Anthropic IPO date, ticker and valuation

• Anthropic IPO date: not set. The Wall Street Journal reports the week of Nov 16 (via Yahoo Finance). That is a press report, not a company statement. The S-1 leaves the share count, price range and prospectus date blank (SEC EDGAR, Anthropic press release).
• Ticker: ANT. Anthropic says it applied to list its Class A common stock on the Nasdaq Global Select Market. It is not trading yet.
• Valuation: not in the S-1. The last private round was $965B post-money in May (Anthropic, via NerdWallet and Yahoo Finance). The WSJ reports an IPO valuation of $1.5 trillion to $2 trillion (via Yahoo Finance).
• Lead banks: Goldman Sachs and Morgan Stanley, in a 22-bank syndicate (CNBC, Yahoo Finance).
• How to buy: not possible yet. No retail broker allocation has been announced (Yahoo Finance).

2. Anthropic IPO date: what is set and what is not

Anthropic filed the S-1 with the SEC on Monday, Oct 26. EDGAR accepted it at 9:00:11 AM ET / 6:00 AM PT (SEC EDGAR filing index). The cover page leaves the number of shares, the price range and the prospectus date blank. That means the Anthropic IPO price range is empty today, and Anthropic's press release says the number of shares and the price range are not determined. Anthropic's press release also says the registration statement "has not yet become effective", so the shares cannot be sold or ordered until it does. When we searched EDGAR at about 5:40 AM PT Tuesday, the original S-1 was the only S-1 on file (the earlier confidential drafts show only as DRS filings), so there is no amended S-1 with a price range yet.

Anthropic IPO when? Here is what the press reports about timing, none of it confirmed by the company:

• WSJ (via Yahoo Finance, Oct 26): targeting a debut the week of Nov 16, raising $100 billion or more.
• Bloomberg (Oct 1): formal marketing could start as soon as the week of Nov 9, which would put trading before Thanksgiving on Nov 26. Bloomberg said the timeline could still shift.
• Reuters (Oct 26, via CNA): Anthropic is expected to go public before Thanksgiving.
• Polymarket (via Yahoo Finance, Oct 26): traders gave 27% odds of a listing by Nov 20, 52.5% by Nov 25 and 82% by year end. That is a prediction market, not a schedule.

One rule puts a floor under the calendar. The SEC says a company that used the confidential review must file publicly at least 15 days before its roadshow. CNBC reports Anthropic filed confidentially in June. Counting 15 days from Oct 26 gives Nov 10 as the earliest roadshow start under that rule (our arithmetic).

So the honest answer to "Anthropic IPO date" is unknown. The next hard signal is an amended S-1 that adds the price range and share count.

3. Anthropic stock symbol, exchange and underwriters

Anthropic says it applied to list its Class A common stock on the Nasdaq Global Select Market under the symbol ANT (Anthropic press release, S-1). ANT is not trading, so it has no price today. CNBC notes that a different company, Anteros Metals, already uses ANT on the Canadian Securities Exchange. Check the exchange and company name before you place any order once trading starts.

Goldman Sachs is listed first on the prospectus and Morgan Stanley second. They are joined by JPMorgan, Citigroup, Barclays, Wells Fargo, Bank of America and 15 other banks, 22 in all (CNBC). The company is selling shares, and selling stockholders are selling more. Anthropic does not receive proceeds from the selling stockholders' shares (S-1). It says it plans to use its own net proceeds for general corporate purposes, including capital expenditures and working capital (CNBC, from the S-1).

4. Anthropic IPO valuation: what is filed and what is reported

• Filed: nothing. With the price range and share count blank, the S-1 gives no price per share and no market value, and you cannot work out a per-share price from it.
• Last private round: $965B post-money after a $65B Series H in May 2026 (Anthropic, via NerdWallet and Yahoo Finance).
• Reported IPO valuation: $1.5 trillion to $2 trillion, raising $100 billion or more (WSJ via Yahoo Finance). Bloomberg reported on Oct 1 that some prospective investors saw $1.8 trillion to $2 trillion as fair. Reuters reported on Oct 26 that some investors now value Anthropic at about $1.5 trillion, down from roughly $2 trillion a week earlier, after it shared some financial details at an investor event.
• Prediction market: Polymarket traders put about 40% on a first-day close above $2 trillion, down from about 62% a month earlier (Yahoo Finance, Oct 26). Those are traders' odds, not a forecast.

To put the range in revenue terms: Anthropic's second-quarter revenue was $11.555B (S-1). Times four is about $46B a year, the same figure Yahoo Finance used. At $1.5 trillion that is about 32 times, and at $2 trillion about 43 times (our arithmetic). Annualizing one quarter is a simple projection, not guidance. The S-1 says Anthropic does not expect revenue to keep growing at comparable rates.

For scale, SpaceX raised $85.7B in its June IPO, and its shares finished last week slightly below where they opened (CNBC).

5. What the S-1 shows: revenue, losses and cash

• Revenue: $16.286B in the first six months of 2026, against $1.163B in the first six months of 2025 and $4.585B for all of 2025 (S-1). That is about 3.6 times all of 2025 in half a year (our arithmetic). Second-quarter revenue was $11.555B.
• Operating result: a $693M operating loss in the first half of 2026, against $2.135B a year earlier (S-1). The second quarter alone showed $974M of operating income, the first positive quarter among the six the S-1 shows.
• Net loss: $80.748B in the first half of 2026 (S-1). Of that, $72.388B is a change in the fair value of convertible notes, derivative liabilities and SAFEs. The S-1 says those changes were primarily driven by a rise in the company's own valuation. NerdWallet describes them as on-paper accounting charges.
• Other expense: the S-1 also shows $8.757B of other expense, net, in the first half of 2026. NerdWallet says investors should not wave that away.
• Compute and infrastructure expense: $8.945B in the first half of 2026 (S-1).
• Cash: $112.4B in cash and cash equivalents plus $19.3B in short-term investments at June 30, 2026 (S-1).

6. How to buy Anthropic stock: IPO shares, after listing, and pre-IPO offers

You cannot buy Anthropic stock on any exchange today, because ANT is not trading. Two routes are real, and one of those is not announced yet. Pre-IPO offers and indirect exposure are covered below as well.

• IPO allocation through a broker (not announced). The S-1 says the underwriters' representatives "may agree to allocate" shares to underwriters for sale to their online brokerage account holders. No retail broker list exists yet (Yahoo Finance). NerdWallet reads the S-1 as pointing to Morgan Stanley's E*TRADE as the clearest possibility. At SpaceX's June IPO, five brokers offered IPO shares directly: E*TRADE, Fidelity, Charles Schwab, Robinhood and SoFi (NerdWallet), and about 30% of the shares went to retail investors (Motley Fool). Nothing like that is announced for ANT.
• How an IPO request usually works. You complete an investor profile, read the prospectus, then place a conditional offer, also called an indication of interest, with the number of shares and your maximum price. It does not guarantee an allocation. You usually learn the night before or the morning of the IPO whether you got shares (Yahoo Finance). Robinhood says its IPO Access shares are allocated by investment banks and assigned randomly, requests open only after the underwriters set a price range, retirement accounts are not eligible, and selling within 30 days can block IPO access for 60 days (Robinhood).
• Broker rules from the SpaceX IPO. Robinhood and SoFi let all account holders in, with no balance minimum. Fidelity usually requires $500,000 in household assets, and lowered that to $2,000 for SpaceX (Motley Fool, BrokerChooser). Whether any of this applies to ANT is unknown. Check your own broker's current rules.
• Buy after it lists. Once ANT trades, any brokerage account that can trade Nasdaq stocks can place an order. A limit order sets the most you will pay. A market order does not.
• Pre-IPO shares: be careful. NerdWallet reports that Anthropic's website says it does not allow share sales without board approval and that purported third-party sales may not be legitimate. Forge Global and Hiive both say Anthropic shares are not available on their platforms. NerdWallet also calls claims by some funds of Anthropic exposure through special purpose vehicles suspicious, and says Anthropic declined to comment. Treat any pre-IPO Anthropic offer as a red flag.
• Indirect exposure. Amazon and Alphabet are shareholders and suppliers. Amazon's convertible notes cannot convert if Amazon would hold more than 12% of Anthropic's capitalization, and Google holds an option to buy up to $10B of non-voting Class N stock at the IPO price in a private placement (S-1). Owning those stocks is not owning Anthropic.

7. Anthropic's share structure: who votes after the IPO

ANT will not be a one-share, one-vote stock. The S-1 calls the structure novel, with "no direct public company precedent."

• Class A (what IPO buyers get): one vote per share (S-1).
• Class F: one share, held by a Founder LLC whose members are the seven co-founders, including Dario and Daniela Amodei. It carries 50.1% of total voting power, including director elections other than the Class T directors, and has no economic rights (S-1).
• Class T: held by the Long-Term Benefit Trust, which elects and removes the Class T directors. They make up a majority of the board. Class T has no economic rights (S-1).
• Class N: no votes, held mainly by strategic partners, and it converts to Class A on a sale to an unaffiliated party (S-1).
• Public benefit corporation: Anthropic must balance stockholders' financial interests with the interests of people affected by its conduct and its stated public benefit purpose (S-1).
• What that means for buyers: the S-1 says the structure makes it harder to replace directors and management and could deprive stockholders of a chance to sell at a premium. Anthropic is also a "controlled company" under Nasdaq rules (S-1).
• Lock-ups: the S-1 staggers insider selling. Some shares can be sold from the first trading day, more on the 27th and 48th days, and some holders are locked up for 365 days (S-1).

8. Anthropic IPO risk factors: what the S-1 spells out

• Losses and margins: the headline $80.7B loss is mostly an accounting charge, but the S-1 says operating margin is expected to fluctuate over time, particularly when substantial new compute arrives and its costs land.
• Compute commitments: Anthropic committed to spend at least $110.0B with Amazon between May 2026 and April 2036, at least about $114.5B with Google between April 2026 and July 2033, and at least $44.9B with Microsoft between November 2026 and May 2033 (different periods), all regardless of actual usage and non-cancelable except for uncured breaches (S-1). CNBC counts $265.6B of non-cancelable purchase commitments at June 30, 2026, and reports a SpaceX compute deal of about $3.1B a month once capacity is delivered.
• Customers: no single customer was more than 10% of revenue in the nine months to Sept 30, 2026, but the top five were about 25%. The S-1 says many top customers are not on long-term contracts or can cut spending at any time. Cloud marketplaces (Amazon, Google and Microsoft) sold 48% of first-half 2026 revenue (S-1).
• Government: the Pentagon labeled Anthropic a supply-chain risk. A federal court in California ruled for Anthropic, but on Sept 25 the D.C. Circuit ruled 2 to 1 that the designation was proper. Anthropic has asked for a rehearing by the full court, and the S-1 says it may see material revenue losses or disruptions (S-1).
• AI safety: the S-1 says advanced AI systems could pose "catastrophic or existential risks to humanity" if misused, replicated, weaponized or allowed to operate with high autonomy.
• Market backdrop: CNBC reports neoclouds CoreWeave and Nebius lost more than 30% in October and that other AI-linked listings were pulled or delayed. Reuters says volatility has thinned the fall IPO calendar.

9. What happens next

• Amended S-1: this is where the price range and share count should appear. Robinhood says it opens IPO requests only after a price range is set.
• Roadshow: reported to start as soon as the week of Nov 9 (Bloomberg). Not confirmed by the company.
• Effectiveness, pricing and first trade: the SEC must declare the registration effective first. The reported debut is the week of Nov 16 (WSJ).
• This week: the Fed decides Wednesday, Oct 28, and Microsoft and Alphabet report after the close that day. Our latest read on Fed hike odds covers the rate side.

FAQ

When is the Anthropic IPO date?

No date is set. The S-1 filed Oct 26 leaves the price range, share count and prospectus date blank. The Wall Street Journal reports a target debut the week of Nov 16 (via Yahoo Finance), which is a press report, not a company statement. As of about 5:45 AM PT on Oct 27, there was no amended S-1 on EDGAR.

What is the Anthropic stock symbol, and is ANT trading yet?

The symbol is ANT. Anthropic says it applied to list its Class A common stock on the Nasdaq Global Select Market under that symbol (Anthropic press release, S-1). It is not trading yet, so there is no ANT price. CNBC notes that Anteros Metals already uses ANT on the Canadian Securities Exchange, so confirm the exchange before you trade.

What is the Anthropic IPO price and valuation?

Neither is in the S-1, because the price range and share count are blank. Anthropic's last private round was $965B post-money in May. The WSJ reports an IPO valuation of $1.5 trillion to $2 trillion (via Yahoo Finance), and Reuters says some investors now value it at about $1.5 trillion. Those are press reports, not company statements.

How do I buy Anthropic stock?

You cannot yet, because ANT is not trading. If a broker gets an IPO allocation, you can request shares with a conditional offer, and you may or may not be allocated any. The S-1 says underwriters may allocate shares to their online brokerage account holders, but no broker is named. Once ANT lists on Nasdaq, any brokerage account that trades Nasdaq stocks can buy it.

Can I buy the Anthropic IPO on Robinhood, SoFi or Fidelity?

Unknown. As of Oct 27, no retail brokerage has been announced for the Anthropic IPO (Yahoo Finance). For SpaceX's IPO, E*TRADE, Fidelity, Schwab, Robinhood and SoFi offered shares (NerdWallet), but that is precedent, not an ANT plan. Robinhood opens IPO requests only after the price range is set, and allocation is not guaranteed.

Can I buy Anthropic stock before the IPO?

Practically, no. NerdWallet reports that Anthropic's website says it does not allow share sales without board approval and that purported third-party sales may not be legitimate. Per NerdWallet, Forge Global and Hiive both say Anthropic shares are not available on their platforms, and some funds' claimed exposure through special purpose vehicles looks suspicious. Treat pre-IPO offers with caution.

What does Anthropic's S-1 say about revenue and losses?

Revenue was $16.286B in the first half of 2026, against $1.163B a year earlier and $4.585B for all of 2025. The net loss was $80.748B, of which $72.388B was a change in the fair value of convertible notes, derivative liabilities and SAFEs that the S-1 ties mainly to the rise in Anthropic's own valuation. The operating loss was $693M for the half (S-1).

What are the biggest risks in Anthropic's S-1?

The S-1 flags large non-cancelable compute commitments, including at least $110.0B with Amazon through April 2036, a top-five customer share of about 25% of revenue, the Pentagon supply-chain risk designation with ongoing litigation, and AI safety risks. It also says founders hold 50.1% of the vote through Class F stock, and the Long-Term Benefit Trust elects a majority of the board.

Bottom line

Anthropic's S-1 settles the ticker, the exchange and the lead banks. It does not settle the IPO date, the price or the valuation, which are still press reports. The numbers it does give are striking: $16.286B of first-half revenue, an operating profit in the second quarter, and an $80.748B net loss that is mostly an accounting charge tied to its own valuation. If you want shares, the only paths are a broker IPO allocation that has not been announced, or an order on Nasdaq after ANT lists. Be wary of any pre-IPO offer. The amended S-1 with a price range is the next thing to watch.
