Anthropic IPO Date: Pricing Nov. 18, Nasdaq Debut Nov. 19

Anthropic's initial public offering now has a confirmed timeline: the company is set to price its shares after the market closes on Wednesday, November 18, 2026, with trading in its Class A common stock due to open on the Nasdaq Global Select Market the next morning, Thursday, November 19, under the ticker "ANT." The offering covers 825 million shares priced at $70 to $78 each, which would raise as much as $64.4 billion and value the AI lab at roughly $1.4 trillion on a fully diluted basis.

Key Dates: Pricing November 18, Trading Begins November 19

Anthropic filed a second amendment to its Form S-1 registration statement with the Securities and Exchange Commission on November 10, 2026, formally launching the roadshow that precedes pricing. That filing, along with Anthropic's own newsroom post announcing the roadshow, set the indicative price range and share count that bankers are now marketing to institutional investors. Reporting since then — including Bloomberg's coverage of the deal's rapid oversubscription — has converged on the same two dates that now anchor the offering: final pricing after the close of trading on November 18, and the start of public trading on the Nasdaq Global Select Market on November 19.

Those dates are the standard mechanics of a U.S. IPO. Once the Securities and Exchange Commission's review period lapses and the roadshow concludes, the underwriters and the company agree on a final offer price based on the orders collected from institutional investors — a process typically completed the evening before the stock opens for trading on the exchange. For Anthropic, that puts pricing on the evening of November 18 and the Nasdaq debut on the morning of November 19, assuming no last-minute delay tied to market conditions or regulatory sign-off.

Offer Terms: Price Range, Share Count, and Deal Size

According to Anthropic's own roadshow announcement, the offering consists of 825,000,000 shares of Class A common stock priced in a range of $70.00 to $78.00 per share. Of that total, 801,351,354 shares are being sold by Anthropic itself, while 23,648,646 shares are being sold by existing stockholders; Anthropic has said it will not receive any proceeds from the shares sold by those selling stockholders. Underwriters also hold a 30-day option to purchase up to an additional 123,750,000 shares, the standard overallotment mechanism used to stabilize trading in the days after a debut.

At the top of the range, the base offering alone would raise approximately $64.4 billion for Anthropic and its selling shareholders combined — a figure that, if it holds, would rank among the largest U.S. IPOs on record and put Anthropic's listing in the same conversation as SpaceX's much-discussed (but still private) valuation benchmarks. The company's shares are expected to list on the Nasdaq Global Select Market, for which Anthropic has submitted a listing application under the symbol ANT.

What the Range Implies for Anthropic's Valuation

At $70 a share, the offering implies a valuation toward the low end of what bankers have floated in recent months; at $78, the top of the range, reporting has pegged Anthropic's fully diluted valuation at approximately $1.4 trillion, inclusive of outstanding stock options and restricted stock units. Several outlets have separately noted that the company's valuation excluding those options and RSUs lands closer to $1 trillion — the gap between the two figures reflects just how much of Anthropic's capitalization sits in employee and founder equity rather than shares already in public hands.

That range sits below the $1.5 trillion to $2 trillion figures that circulated in press speculation earlier in the fall, when AI valuations generally were running hotter. It's a reminder that an indicative price range set in an S-1 amendment is a marketing tool, not a guarantee — the final price on November 18 could land anywhere inside the $70–$78 band, or, in a strong enough book, even above it.

Underwriters and Bookrunners

Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC are listed as the sources for copies of the preliminary prospectus in Anthropic's own roadshow materials, confirming their role as the lead underwriters steering the deal through pricing. Anthropic had previously named Morgan Stanley, Goldman Sachs and JPMorgan Chase among the banks advising on the offering when the company first moved toward going public earlier in 2026, before the underwriting syndicate was finalized for the public filing.

Investor Demand Heading Into Pricing

Demand for the offering has reportedly run well ahead of the shares on offer. Bloomberg reported on November 12 that the deal was already several times oversubscribed, with order books covering the offering roughly six times over — a signal, if it holds through the rest of the roadshow, that bankers may have room to price at or above the top of the stated $70–$78 range rather than below it. Strong early demand is also one reason the November 18 pricing date has stayed on track even as broader tech markets have been choppy in the lead-up to the listing.

The Concurrent $26 Billion Private Placement

Separate from the public offering, Anthropic has arranged a concurrent private placement of roughly $26 billion in non-voting Class N shares, sold at the same price set in the IPO, to a group of strategic technology partners. Reporting has named chip and cloud companies including Nvidia, Google, Microsoft, AMD, Broadcom, Micron and TSMC among the buyers in that placement — relationships that mirror the compute and cloud partnerships already underpinning Anthropic's business. The private placement is structured to close alongside the public offering but does not add to the 825 million shares being sold to public investors.

How IPO Pricing Day Actually Works

For investors unfamiliar with the mechanics, "pricing" and "trading" are two distinct events. On the pricing date — November 18 for Anthropic — the company and its underwriters set the final per-share price after the stock market closes, based on the demand recorded during the roadshow. That price determines how much Anthropic and its selling stockholders actually raise. The following morning, November 19, the stock becomes available to trade on the exchange for the first time; the opening trade is typically set through an auction process run by the designated market maker, and it can open well above or below the IPO price depending on demand from the broader market, not just the institutional investors who received allocations the night before.

That distinction matters for anyone trying to get in on day one. Retail investors generally cannot buy at the $70–$78 IPO price itself unless their brokerage has access to a retail allocation; most will be buying at whatever price the stock opens at on Nasdaq once trading begins on November 19. Pandromeda's guide to buying ANT stock walks through the mechanics of getting an order in once trading opens.

How Anthropic Got Here

Anthropic first disclosed that it had confidentially submitted a draft registration statement to the SEC on June 1, 2026, saying at the time that any offering would "depend on market conditions and other factors." The company filed its public S-1 on October 26, 2026, formally naming its intent to list on the Nasdaq Global Select Market under "ANT," and followed with two amendments — on November 2 and November 10 — that progressively filled in the offering's terms, culminating in the $70–$78 price range and 825-million-share count now being marketed. Pandromeda covered the moment the range itself was set in our earlier report on Anthropic's IPO price range; what's new this week is that the pricing and trading dates have now firmed up around November 18 and 19.

The IPO arrives as Anthropic continues to push out new products on the Claude side of its business — most recently the Claude Fable 5.2 and Mythos 5.2 model releases — underscoring that the listing is as much a bet on Anthropic's continued model and product cadence as it is on its current revenue run rate.

What Could Still Change Before November 18

Every figure in this piece — the price range, the share count, the valuation, and even the dates themselves — comes from a registration statement that has not yet become effective and a roadshow that concludes only once institutional orders are finalized. Anthropic has explicitly cautioned, in its own SEC filings, that the number of shares offered and the price range are subject to change, and that the offering overall depends on market conditions. A sharp swing in equity markets, a regulatory snag, or unexpectedly weak demand in the offering's final days could still push the final price toward the bottom of the range, delay pricing past November 18, or in a worst case postpone the listing entirely. Conversely, the oversubscription reported by Bloomberg this week is the kind of signal that typically pushes pricing toward — or above — the top of the range rather than below it.

Why the Date Matters More Than the Range Right Now

Since Anthropic's $70–$78 price range was set on November 10, most of the public discussion has focused on what the company might be worth. But for anyone actually trying to track or trade the listing, the more actionable update is the calendar: pricing after market close on November 18, first trades on Nasdaq the morning of November 19. That's the window in which Anthropic stops being a private company valued in funding rounds and becomes a publicly traded one valued, every trading day, by whoever is buying and selling ANT shares on the open market.

What's Next

Barring a delay, Anthropic's underwriters will collect final orders through the close of trading on November 18, set the IPO price that evening, and open ANT for trading on the Nasdaq Global Select Market the morning of November 19. In the days that follow, watch for: the final price itself (and whether it lands inside, above, or below the $70–$78 range); the stock's first-day trade relative to that price; confirmation of how much Anthropic and its selling stockholders actually raised once the underwriters' 30-day overallotment option is factored in; and whether the concurrent $26 billion private placement closes on schedule alongside the public offering. Pandromeda will update this report once pricing is confirmed and again once ANT opens for trading.
