When Is the Anthropic IPO? Anthropic IPO Date, Plans and Status for 2026

When is the Anthropic IPO? As of November 12, 2026, Anthropic has not announced an IPO date.

What is confirmed: it filed a public S-1 on October 26, set a price range of $70 to $78 per share in an amended filing on November 10, and will list on the Nasdaq Global Select Market under the ticker ANT.

What is reported: a first trade in the week of November 16, with some reports naming November 19 or 20, ahead of Thanksgiving on November 26.

Key Takeaways

• Anthropic filed its public Form S-1 with the SEC on October 26, 2026, five months after the confidential draft of June 1, filed Amendment No. 1 with third-quarter results on November 2, and filed Amendment No. 2 with the price range on November 10.
• Confirmed by the filing: Class A common stock, the Nasdaq Global Select Market, the ticker ANT, and 22 underwriters led by Goldman Sachs and Morgan Stanley.
• Also confirmed since November 10: 825,000,000 Class A shares at $70.00 to $78.00 per share.
• Not confirmed: the final price, the pricing date and the listing day, which come with the final prospectus and the exchange's listing notice.
• The roadshow began on November 10, 2026, according to media reports, the first day the SEC's 15-day rule allowed.
• The range implies a valuation of about $916.1 billion to $1.02 trillion on shares outstanding after the offering, against the $965 billion post-money valuation from the May 2026 Series H.

Anthropic IPO at a Glance

The Anthropic IPO is a filed, undated Nasdaq listing: the paperwork is public, the exchange, ticker and price range are set, and the final price and date are not.

• Company: Anthropic, PBC, a Delaware public benefit corporation and the developer of the Claude models.
• Ticker: ANT, per the application disclosed in the S-1.
• Exchange: Nasdaq Global Select Market.
• Price range: $70.00 to $78.00 per share, filed November 10, 2026.
• Shares offered: 825,000,000 Class A shares.
• Lead banks: Goldman Sachs and Morgan Stanley, listed first on the cover among 22 banks.

• Status: roadshow under way (reported); pricing date not announced.

The confirmed terms of the Anthropic IPO as of November 12, 2026, from the public Form S-1 and its two amendments.

Has Anthropic Announced an IPO Date?

Anthropic has not announced an IPO date as of November 12, 2026.

The amended S-1 filed on November 10 sets the number of shares and the price range, but not a pricing date or a listing day.

Anthropic's own filing announcement confirms the Nasdaq application and the ANT symbol but gives no timeline.

What does exist is a procedural floor, and it has now been passed.

A company that used the SEC's confidential review process must file publicly at least 15 days before its roadshow begins, under the Division of Corporation Finance's expanded draft registration procedures of March 3, 2025.

Counting 15 days from October 26 put the earliest roadshow start at November 10, 2026, and media reports say the roadshow began that day, as covered in our Anthropic IPO roadshow guide.

Pricing follows the roadshow, and the first trade follows pricing by one day, so the listing sits in the second half of November if the reported schedule holds.

The most specific timing so far comes from press reports: media reports say Anthropic aims to debut in the week of November 16, 2026, with some naming November 19 or 20, and Anthropic has not confirmed it.

Bloomberg reported on October 1 that Anthropic wanted to start trading before Thanksgiving, November 26, when US markets are closed.

The sequence so far is normal: a first public S-1 rarely carries a price range, an amended filing adds it as the roadshow begins, and the final price is set the evening before trading.

Anthropic IPO Timeline: Confirmed, Reported and Expected

The Anthropic IPO timeline has four confirmed dates, one reported estimate and several expected steps, and each entry below carries its label.

• June 1, 2026 — Confirmed: Anthropic announced that it had confidentially submitted a draft S-1 to the SEC.
• October 26, 2026 — Confirmed: the public Form S-1 was filed, naming the Nasdaq Global Select Market, the ticker ANT and 22 underwriters.
• November 2, 2026 — Confirmed: Amendment No. 1 (Form S-1/A) added third-quarter 2026 results and the US retail brokerage platforms, and left the share count and the price range blank.
• November 10, 2026 — Confirmed: Amendment No. 2 added the share count, 825,000,000 Class A shares, and the price range, $70 to $78.
• Roadshow, from November 10, 2026 — Reported: media reports say marketing began on the first day the 15-day rule allowed.
• Debut the week of November 16 — Reported: media reports say Anthropic aims to list that week, with some naming November 19 or 20.
• Pricing — Expected: the underwriters set the final price the evening before the first trade, after the roadshow; date not announced.
• First trade — Expected: ANT opens on Nasdaq the day after pricing, once the SEC declares the registration effective; date not announced.
• Settlement — Expected: trades settle one business day after the trade (T+1).
• Post-listing lock-up releases — Confirmed structure: the S-1 sets a staggered release schedule for the lock-up period after the listing, generally 180 days, with the largest holders fully free to sell only by the third-quarter 2027 results or day 365, whichever comes first.

What the Market Expects

The market expects Anthropic to list in late November 2026, but that is a market expectation, not a confirmed date.

Prediction markets put odds on each possible listing date, and the current ladder is tracked in our guide to prediction-market odds on Anthropic's listing timing.

What Would Confirm the IPO Date?

Three official signals would confirm the Anthropic IPO date: the SEC declaring the registration statement effective, a pricing announcement followed by a final 424(b)(4) prospectus, and a Nasdaq notice that ANT will begin trading.

• SEC effectiveness: the SEC declares Anthropic's registration statement effective, which allows the shares to be sold.
• Pricing: Anthropic announces the final IPO price, and a final 424(b)(4) prospectus with that price follows.
• Nasdaq notice: Nasdaq publishes an IPO notice for ANT that sets the first trading day.

Until those appear, any specific date remains a report.

Anthropic IPO Status: Confirmed, Reported, or Just Noise

The exchange, the ticker, the lead banks, the price range and the filing itself are confirmed by the S-1 and its amendments; the listing day and the final share price are confirmed by no one.

• Anthropic has filed to go public — Confirmed: Form S-1 on EDGAR, filed October 26, 2026.
• The exchange is Nasdaq — Confirmed: the S-1 discloses an application to list on the Nasdaq Global Select Market.
• The ticker is ANT — Confirmed: S-1 cover page.
• Goldman Sachs and Morgan Stanley lead the deal — Confirmed: the cover lists 22 underwriters with those two banks first.
• The price range is $70 to $78 — Confirmed: Amendment No. 2, filed November 10, 2026; the final price is not set.
• The deal covers 825,000,000 Class A shares — Confirmed: Amendment No. 2; that is $57.75 billion to $64.35 billion at the range, before fees.
• Anthropic is worth $965 billion — Confirmed as of May 2026: the Series H announcement of May 28, 2026; the IPO valuation is a separate number.
• The IPO valuation will be $1.5 trillion to $2 trillion — Reported, and now out of line with the filing: that was a discussion range in press reports, while the filed range implies about $916.1 billion to $1.02 trillion.
• Retail investors will get 15% to 20% of the shares — Reported: Bloomberg reported on October 28 that Anthropic could earmark that share for retail investors, with JPMorgan leading the retail allocation.
• The IPO will be in November 2026 — Not confirmed: the roadshow is reported to be under way, but no pricing date or listing day has been announced.

Which Anthropic IPO claims are confirmed, reported or not confirmed, and the basis for each.

What Anthropic Has Actually Said

Anthropic has made two statements about the offering, and neither names a date.

On June 1, 2026 it announced the confidential draft submission and said the offering would depend on market conditions and other factors.

On October 26, 2026 it announced the public filing, the exchange and the Anthropic stock ticker, ANT.

Every figure tied to the offering comes from the S-1, which is marked "subject to completion," so the financial history is fixed while the offering terms are not.

What Is Only Market Expectation

Reported timelines, anchor investors and IPO valuations are not company statements, and the filing does not confirm them.

Prediction-market prices and pre-IPO product quotes measure what traders expect, which is useful information but not a disclosure.

One expectation has already become fact: reports named Nasdaq as the venue in September, and the S-1 confirmed it in October.

What the Public S-1 Changed

The public S-1 replaced five months of estimates with filed numbers and disclosed terms.

The filing reports revenue of $16.29 billion for the six months ended June 30, 2026, against $1.16 billion a year earlier.

It reports a net loss of $80.7 billion for the half, of which roughly $72.4 billion is a non-cash change in the fair value of convertible notes rather than cash spent.

It also reports $131.7 billion of cash and short-term investments at June 30, 2026, and a share structure in which public Class A holders get one vote each while a founders' share controls 50.1% of the vote.

Amendment No. 1, filed November 2, added the third quarter: revenue of $16.96 billion, up about 47% from the second quarter, and a GAAP operating loss of $567 million after an operating profit in the second quarter, as broken down in Anthropic's Q3 2026 results.

Amendment No. 2, filed November 10, added the offering terms: 825,000,000 Class A shares at $70 to $78, which values Anthropic at about $916.1 billion to $1.02 trillion on shares outstanding after the offering, plus a $26.0 billion concurrent private placement.

The full numbers are in the Anthropic revenue and profitability guide.

The ownership and control details, and how the private mark relates to the filed IPO range, are in the guide to Anthropic's IPO valuation.

Checking EDGAR and the Company Newsroom

Two sources settle any Anthropic IPO claim: the SEC's EDGAR database and Anthropic's newsroom.

On EDGAR, search for the filer "Anthropic, PBC" and check both form types S-1 and S-1/A; Amendment No. 2 of November 10, 2026 is the latest document, and it carries the price range.

Anthropic's newsroom has published a notice at each step, so a claim that appears on neither source is a report, not a fact.

The step-by-step guide to finding the filing is in Where Is Anthropic's S-1?

Day-to-day developments, each labeled confirmed or reported, are logged in the latest Anthropic IPO news page.

Anthropic IPO Plans for 2026: What Still Has to Happen

Anthropic's IPO plans for 2026 still need four things to happen before ANT can trade, and none of them is fully in Anthropic's control.

• SEC review: the staff can issue comments on the public filing, and each round takes time to answer.
• Nasdaq approval: the listing application is pending and is confirmed at pricing.
• Investor demand: the roadshow sets the final price in practice, whatever range the amended filing proposes.
• Market conditions: Anthropic itself named these as a condition of the offering in June.

A fifth variable is the share structure: the summary risk factors in the Anthropic IPO prospectus flag a "novel capital structure" and concentrated voting power, and how investors value one-vote Class A shares under it will shape the price range.

MEXC View: Which IPO Date Signals Can You Trust?

Our view is simple: on the Anthropic IPO date, filings and official notices are the timetable, and headlines are the weather report.

This year, reported targets moved from October to mid-November, while the filed steps arrived in a steady sequence: the public S-1, the third-quarter amendment and then the price range.

Each filing has also narrowed what is left to report, and after the November 10 amendment the only open items are the final price, the pricing date and the first trading day.

That is why we treat the SEC's effectiveness notice, the 424(b)(4) prospectus and Nasdaq's trading notice as the only confirmations of the date, and a dated headline as a reason to check EDGAR, not as an answer.

Can You Buy Anthropic Stock Before the IPO?

No, Anthropic stock cannot be bought before ANT starts trading, and the routes that give pre-listing exposure are compared in when and how you can buy Anthropic stock before the IPO.

Getting shares in the IPO itself is a separate step that opens only when the deal prices, through a broker that receives part of the allocation, and the broker programs and the offerings outside the US are compared in the guide to buying Anthropic IPO shares at the offer price.

After the listing, anyone with a broker that trades Nasdaq stocks can buy ANT at the market price, which can differ from the offer price.

On MEXC, the Anthropic Pre-IPO Countdown page tracks the steps between the filing and the first trade, so the status above can be checked against it as the roadshow and the pricing arrive.

Frequently Asked Questions

When is the Anthropic IPO?

As of November 12, 2026 Anthropic has not announced an IPO date; media reports point to a first trade in the week of November 16.

Not the final price; the November 10 S-1/A sets a range of $70 to $78 per share, and the final price is set at pricing.

Is the Claude IPO the same as the Anthropic IPO?

Yes, "Claude IPO" refers to the same event, because Claude is Anthropic's product and the company going public under the ticker ANT is Anthropic, PBC; there is no separate Claude stock.

Is Anthropic publicly traded?

No, Anthropic is still private; it filed its public S-1 on October 26, 2026, and ANT trades on Nasdaq only after the SEC declares the registration effective and the deal prices.

Has Anthropic filed for an IPO?

Yes, Anthropic submitted a confidential draft S-1 on June 1, 2026, filed the public Form S-1 on October 26, 2026 and filed amendments on November 2 and November 10, 2026.

What is the status of the Anthropic IPO?

As of November 12, 2026, the Anthropic IPO is filed but not priced: the price range is $70 to $78, the Nasdaq listing as ANT is set and the roadshow is reported to be under way, while the final price and the listing day are still pending.

What is Anthropic's ticker symbol?

Anthropic has applied to list its Class A common stock under the symbol ANT.

Where will Anthropic stock trade?

Anthropic stock will trade on the Nasdaq Global Select Market, and the S-1/A names no other listing venue.

When will Anthropic go public?

Reports point to a first trade in the week of November 16, 2026, with some naming November 19 or 20, but Anthropic has confirmed no date.

What is Anthropic's IPO valuation?

The filed range implies about $916.1 billion to $1.02 trillion on shares outstanding after the offering, against a last confirmed private valuation of $965 billion from May 2026, and the final figure is set at pricing.

Will Anthropic go public before OpenAI?

Yes on current facts, because Anthropic has a public S-1 on EDGAR while OpenAI has only a confidential submission and is reported to be leaning toward 2027, as the Anthropic vs OpenAI IPO comparison sets out.

The Bottom Line

One filing is public, one exchange, one ticker and one price range are confirmed, and one date is still blank.

Treat any pricing date or first trading day as a report or a market expectation until Anthropic, the SEC or Nasdaq confirms it.

Check EDGAR and Anthropic's newsroom before acting on a headline, and read what any pre-IPO product actually delivers before committing money.
