Key Highlights

● IPO valuation chatter once ran as high as about $2 trillion.

● It moved to roughly $1.4 trillion to $1.5 trillion.

● A later report put it at $1.2 trillion to $1.3 trillion.

● Another report cited $80 billion to $100 billion in fundraising.

Not long ago, talk around Anthropic's initial public offering ran as high as about $2 trillion. Then the AI trade wobbled, and the reported figures followed it down. Chatter moved to roughly $1.4 trillion to $1.5 trillion, and on November 6 reports reported a range of $1.2 trillion to $1.3 trillion, with some estimates as low as $1.1 trillion, according to media reports.

Another report gave a wider range of $1.25 trillion to $1.75 trillion, alongside a fundraising target of $80 billion to $100 billion. None of these figures is official. As of Monday, November 9, 2026, no price range or share count was on file, reports said.

Still far above the last private round

Even the cooled numbers are well above where private investors last valued the company. Anthropic's last private valuation was about $965 billion, set in a funding round in May. A public listing at the lower end of the reported range would still mark a sizable step up.

The company's filings help explain the ambition. Anthropic's S-1 cites third-quarter Revenue of $17.0 billion and roughly $895 billion of AI infrastructure commitments through 2045. It plans to list on the Nasdaq Global Select Market under the ticker "ANT," with 22 underwriters led by Goldman Sachs (NYSE:GS) and Morgan Stanley (NYSE:MS).

Why the chatter cooled

The timing of the slide lines up with the AI sell-off. After the November 3 midterm elections, investors dumped AI stocks on fears that the new Democratic majorities in Congress could restrict data-center construction, reports said. The Nasdaq Composite fell into correction territory on November 5, according to market coverage, and reports said that Goldman Sachs' broad AI basket was roughly a quarter below its peak heading into November 4.

When publicly traded AI stocks fall, the comparisons bankers use to value a new listing fall too. That makes it harder to justify the loftiest figures, regardless of how fast the company itself is growing.

The spending debate weighs as well. Goldman Sachs sees AI capex growth peaking, and a research firm has warned that AI spending has outpaced operating cash flow, according to market reports. Those concerns are likely to be raised for a company with infrastructure commitments as large as Anthropic's.

Monday's rebound offers some relief

The market's mood improved on Monday. The S&P 500 jumped 173.08 points to 7,549.94, its best day since April 8, and the PHLX Semiconductor index rocketed to 10,033.93. A JPMorgan strategist called the sell-off "an intra-cycle reset," and a Morgan Stanley strategist said it "is likely the final stage of this correction."

Still, not all AI names rallied. Nvidia (NASDAQ:NVDA) slid amid an independent review by its board involving CEO Jensen Huang, and Citi downgraded US stocks and global tech to neutral, according to market data.

Pricing Details Still Pending

The most important number will be the official price range in an amended filing, which would replace the chatter with something concrete. The Information has reported a listing could come the week of November 16, though that has not been confirmed. Investors will also watch how other AI companies trade: CoreWeave (NASDAQ:CRWV) and Nebius Group (NASDAQ:NBIS) report this week, and Nvidia reports on November 17. A strong run in AI stocks could lift valuation talk again; a fresh sell-off could push it lower.
