Anthropic, the artificial intelligence company behind the Claude chatbot, has finally locked in the specifics of its blockbuster initial public offering. In a securities filing on Nov. 10, the company set a proposed price range of $70 to $78 per share and said it plans to price the deal on Nov. 18 before shares begin trading on the Nasdaq on Nov. 19 under the ticker symbol ANT.

At the top of that range, the San Francisco-based AI lab would command a valuation of roughly $1.4 trillion on a fully diluted basis — TechCrunch pegged the precise figure at $1.404 trillion — making its debut one of the largest IPOs in U.S. market history and a defining test of Wall Street's appetite for artificial intelligence.

Anthropic Sets the Stage for a $1.4 Trillion Market Debut

The company will offer 825 million Class A shares at between $70 and $78 apiece, according to the amended S-1 filing reported by CNBC. That translates to a base raise of up to $64.4 billion, with underwriters holding an over-allotment, or greenshoe, option that could add roughly $9.7 billion more — pushing the total potential offering toward $74 billion at the top of the range.

Goldman Sachs and Morgan Stanley are leading the underwriting effort for a 22-bank syndicate, a marquee role that pits two of Wall Street's biggest firms against each other for a slice of the AI boom. Anthropic launched its investor roadshow on Nov. 10 and is expected to close its offer period on Nov. 17, one day before pricing.

From OpenAI Departure to Nasdaq: How Anthropic Got Here

Anthropic was founded in 2021 by siblings Dario Amodei, who serves as CEO, and Daniela Amodei, along with a group of former OpenAI researchers who left over concerns about AI safety. The company's flagship product, Claude, has become one of the most widely used AI assistants, competing directly with OpenAI's ChatGPT and Google's Gemini.

  • Oct. 27, 2026: Names Goldman Sachs and Morgan Stanley as lead underwriters
  • Nov. 10, 2026: Sets a $70–$78 price range in an amended S-1 and launches its roadshow

  • Nov. 19, 2026: Shares expected to begin trading on Nasdaq under ANT

Explosive Growth — and a Heavy Loss — in the Numbers

Anthropic's financials tell a story of breakneck expansion. Revenue hit $16.8 billion in the third quarter of 2026, up roughly 47% from $11.6 billion in the second quarter and more than three times the $4.7 billion generated in the first quarter. For the nine months ended Sept. 30, revenue reached about $33.2 billion, a jump of roughly 1,200% from the year-ago period, and far above the $4.59 billion the company recorded for all of 2025.

The company has also begun to show operating leverage. Anthropic posted an operating profit of $974 million in the second quarter, or $2.24 billion on an adjusted basis, and it has told investors it achieved profitability ahead of the IPO. Still, its first-half net loss ballooned to $80.7 billion, driven largely by a one-time charge tied to its compute commitments, which the filing pegged at around $637 billion.

Customer retention is a bright spot: Anthropic reported roughly 900% net revenue retention and a base of about 11,900 enterprises spending more than $100,000 a year — up from fewer than 1,000 just a year earlier.

Why the $1.4 Trillion Price Tag Matters for Everyday Investors

The valuation itself has been a moving target. Early reports suggested Anthropic could seek a price tag as high as $2 trillion, and prospective investors later pushed for something closer to $1.5 trillion. The final range — which values the company at up to about $1.4 trillion on a fully diluted basis, or roughly $1.3 trillion by other measures — reflects a more cautious markdown as IPO investors balked at richer terms.

The debut carries major implications for the broader AI trade. Amazon and Google, Anthropic's two largest backers, could see the value of their stakes swell by hundreds of billions of dollars; Reuters calculated the combined value could reach about $411 billion at the top of the range. For retail investors, the IPO offers a rare chance to buy a pure-play frontier AI company, but it comes with warnings: Anthropic's own prospectus flags AI backlash, intense competition, and even existential risks from advanced AI as key threats — a theme CEO Dario Amodei reportedly raised within the first 30 seconds of the company's roadshow video.

Some prominent voices are skeptical. Investor Michael Burry, famous for predicting the 2008 housing crash, has warned that the OpenAI and Anthropic IPOs could mark the top of an AI investment bubble, questioning whether the enormous sums flowing into AI can ever justify such valuations.

Where the IPO Stands Right Now

As of the latest filings, the roadshow is underway and the offer period is expected to close Tuesday, Nov. 17. Pricing is slated for Nov. 18, with trading to follow on Nov. 19. Investors who want to participate generally need a funded brokerage account and should check whether their broker offers access to IPO shares, since allocations are often limited and typically reserved for larger accounts.

What Happens Next for the ANT Ticker

If demand is strong, underwriters can exercise the greenshoe option to sell additional shares, and the final price could land at or above the top of the range. A well-received debut would likely validate the AI IPO pipeline, while a sharp selloff could cool sentiment across the sector. Either way, all eyes will be on the first day of trading to see whether Anthropic can hold — or exceed — its trillion-dollar price tag in the open market.

  • Anthropic plans to price its IPO on Nov. 18 and begin trading Nov. 19 on Nasdaq under the ticker ANT.
  • The company set a price range of $70 to $78 per share for 825 million shares, targeting a valuation of up to about $1.4 trillion.
  • Revenue grew roughly 1,200% year over year, but a one-time charge pushed first-half net losses to $80.7 billion.
  • Amazon and Google stand to gain hundreds of billions of dollars on their stakes.
  • The debut is a key test of investor appetite for AI — and a potential signal for the broader market.
