Anthropic's $80-100 Billion IPO: Filed Facts vs. Investor Talk

Anthropic wants to raise $80 billion to $100 billion at a valuation of $1.25 trillion to $1.75 trillion before Thanksgiving, according to investors cited by the Financial Times — and none of those figures appears in its SEC filings. The amended S-1, filed Nov. 2, fixes the ticker, the exchange, the banks and an unusual control structure. It leaves the price range, share count and offering date blank. The gap between what is filed and what is leaked is the story.

What the filings actually confirm

Anthropic, PBC filed a confidential draft on June 1, a public S-1 on Oct. 26 and Amendment No. 1 on Nov. 2. The prospectus confirms Class A shares on the Nasdaq Global Select Market under the symbol ANT. Goldman Sachs and Morgan Stanley lead 22 underwriters, followed by J.P. Morgan, Citigroup, Barclays, Wells Fargo and BofA Securities.

The offering mixes new shares with sales by existing holders. Anthropic receives no proceeds from the selling stockholders. Public offerings are planned in Australia, Canada, parts of the European Economic Area, Japan, Switzerland and the U.K., though the company will not list outside the U.S. Anthropic is a Delaware public benefit corporation, and its board must weigh its stated purpose — "the responsible development and maintenance of advanced AI for the long-term benefit of humanity" — alongside shareholder returns.

Everything that sets the price is missing. The cover page reads "between $ and $" per share. Share counts, the underwriting discount and use-of-proceeds remain blank. EDGAR showed no further amendment as of Nov. 8.

What do the numbers show?

Revenue rose in every quarter the filing covers, from $376 million in Q1 2025 to $16.96 billion in Q3 2026. That is a twelvefold jump in seven quarters. First nine-month 2026 revenue was $33.2 billion, against $2.5 billion a year earlier.

The detail matters:

• Q3 2026 revenue: $16.96 billion; compute and infrastructure cost: $9.86 billion; operating loss: $567 million.
• Q2 2026 was the only quarter with operating profit — $974 million — but a $66.3 billion net loss.
• Net losses stem mainly from fair-value changes on convertible notes, derivatives and SAFEs: $94.3 billion in the first nine months, against a $1.26 billion operating loss.
• Price cuts and contractual discounts removed about $600 million from Q3 revenue.
• More than 11,900 customers pay $100,000 or more a year; about 250 pay above $10 million.

Compute and infrastructure fell from 251% of revenue in Q1 2025 to 48% in Q2 2026, then rose to 58% in Q3 as committed capacity came online. The company held $131.8 billion in cash and short-term investments at Sept. 30.

How big are the compute obligations?

The obligations dwarf the cash. Anthropic disclosed roughly $895.4 billion in purchase and lease commitments, "substantially all of which is related to compute and infrastructure," per the filing. Some $447.5 billion is due before the end of 2030, and $69.8 billion falls within 12 months of Sept. 30. That liability schedule explains why an $80-100 billion raise is not optional spending money; it is working capital for contracted capacity.

Who will control the company?

Buyers of ANT get one vote per share and little say. Immediately before the offering, Anthropic issues a single Class F share to an LLC owned by Dario Amodei, Daniela Amodei and the five other co-founders. That share carries 50.1% of the vote on general matters and has no economic rights. The Long-Term Benefit Trust holds a Class T share letting it elect a board majority. Class N shares, held mainly by strategic partners, carry no vote until sold. Anthropic will be a "controlled company" under Nasdaq rules.

The filing also commits equity to the benefit purpose. Beyond the initial 5% contribution to the Anthropic Public Benefit Fund, the board may issue up to another 2% of shares each time the stock rises 50% above a prior milestone. Co-founders pledged 80% of their personal equity to philanthropy. Lockups run until shortly after Q3 2027 results or 365 days post-IPO for insiders; 180 days for most others.

What is still guesswork on valuation?

Every valuation figure comes from investors talking to reporters. Anthropic has declined to comment. The talk has fallen in steps. Bloomberg reported figures as high as $2 trillion circulating in early October. Reuters then reported roughly $1.5 trillion discussed at an investor day. After the Nov. 5 Nasdaq 100 rout — a record 6.4% one-day drop — The Wall Street Journal reported one large buyer saw closer to $1 trillion, with the raise possibly shrinking to about $80 billion.

Bloomberg now reports investors discussing $1.2-1.3 trillion, down from $1.4-1.5 trillion communicated to bankers. One investor told the FT he expects Anthropic to "price it very conservatively, call it $1.5tn, and go up from there." Another told CNBC that $1.5 trillion was "a stretch" and $1-1.25 trillion more likely. Kalshi odds of a listing before December were back above 80% on Nov. 8, per Seeking Alpha.

The filing permits rough per-share arithmetic. Anthropic contributed 846.8 million Class N shares equal to 5% of fully diluted stock, implying about 16.9 billion shares. On that base, $1.25 trillion works out to roughly $74 a share; $1.75 trillion to about $103. Those are estimates, and IPO share issuance would raise the count.

What happens before ANT trades?

No date is set. The Information and CNBC reported a roadshow expected the week of Nov. 6 reports, with Yahoo Finance citing pricing possibly Nov. 13 and trading from Nov. 16. CNBC tied the Nov. 5 sell-off partly to midterms: local communities rejected data-center measures in 40 of 41 ballot fights. Anthropic must still file a price-range amendment before any of the reported terms become real, and until that filing lands, every valuation number on this page remains an investor's talking point rather than a deal.
