Anthropic IPO Six Times Oversubscribed Ahead of Thursday Debut

Anthropic's IPO is roughly six times oversubscribed, Bloomberg reported, putting the AI lab on track for a November 19 Nasdaq debut at a fully diluted valuation of up to $1.4 trillion under the ticker "ANT." The book of orders runs about six times the shares on offer.

The company and selling shareholders plan to sell 825 million Class A shares at $70 to $78 each, raising up to $64.4 billion. A concurrent $26 billion private placement to strategic partners lifts the total capital raise to $90.4 billion — the largest first-time share sale on record, eclipsing SpaceX.

What does the deal look like?

Goldman Sachs and Morgan Stanley lead a 22-bank syndicate. Bankers have told prospective investors that existing backers will get priority in allocation, leaving new buyers with smaller slices than they requested. Some institutions are already flipping expected allocations in secondary markets. Pre-IPO holders are packaging stakes through special purpose vehicles.

The private placement commits AMD, Broadcom, Google, Micron, Microsoft, Nvidia and TSMC to buy Class N shares — non-voting, converting to Class A on transfer — at the IPO price. Nvidia alone pledged about $10 billion.

How fast is revenue growing?

The prospectus shows revenue accelerating from $4.6 billion in full-year 2025 to $33 billion in the first nine months of 2026. Annualized "run-rate revenue" hit $81 billion as of October 31, up from $71 billion at end-September and $65 billion at end-July. The Q3 2026 quarter alone recorded $17 billion.

Anthropic defines run-rate as consumption fees over a trailing 28-day period multiplied by 13, plus one month of subscription fees multiplied by 12 — a self-defined snapshot, not a forecast. About 80% of revenue is "pay-for-intelligence," meaning token-metered usage. Subscriptions make up the rest.

What sits behind the valuation?

The filing discloses approximately $900.9 billion in aggregate purchase commitments and leases, "substantially all" for compute and infrastructure. $451.6 billion falls due before 2031; the remainder stretches to 2045. About $70.7 billion comes due in the 12 months after September 30, 2026. Morningstar analyst Malik Ahmed Khan noted the commitments are structured over more than a decade.

Anthropic says it manages compute as a fungible pool across AWS Trainium, Google TPUs, Nvidia GPUs and AMD GPUs, claiming efficiency gains from dynamic orchestration.

Who controls the company?

Anthropic is a Delaware public benefit corporation. A Long-Term Benefit Trust holds Class T shares electing four of seven board seats — a majority — with no economic rights. A single Class F share held by a Founder LLC of seven co-founders, including CEO Dario Amodei and President Daniela Amodei, carries 50.1% of general voting power, including election of the remaining three directors. Public Class A shareholders hold 49.9% of general voting power. The structure makes Anthropic a "controlled company" under Nasdaq rules.

What about Nvidia?

The IPO arrives as Nvidia, Anthropic's key chip supplier and investor, reels from the ouster of CEO Jensen Huang over reported personal misconduct, including an affair with an alleged Chinese agent. Nvidia shares have fallen 27% since early October. Nvidia remains committed to the private placement and to "tens of billions" in chip supply agreements. The roadshow includes a livestream with Amodei and JPMorgan Chase CEO Jamie Dimon.

Why are some investors skeptical?

The AI trade has sold off amid midterm-election fears of data-center regulation, weak hyperscaler free cash flow and the Nvidia shock. Prospective buyers discussed lowering Anthropic's valuation to $1.1–1.3 trillion before the oversubscription news.

Ariel Investments co-CEO Mellody Hobson called the market's fixation on one IPO "worrisome" and "single-minded," comparing the mood to 1999 and flagging "circular financing" among AI players. Morningstar's Khan assigns a $92-per-share fair value, or $1.7 trillion, citing a 47% five-year revenue CAGR and durable technological advantage. William Blair's Arjun Bhatia projects $135 billion revenue by 2027, calling 11 times that estimate an attractive multiple for a once-in-a-generation company.

What remains unknown?

The final price will be set November 18. The prospectus warns that oversubscription does not guarantee strong aftermarket trading. A $21.9 billion non-cash charge in Q3, from fair-value changes on convertible notes, derivatives and SAFEs, underscores the complexity of the pre-IPO capital structure. Whether the LTBT and Founder LLC can operate smoothly under public-company scrutiny, whether the $900.9 billion in compute commitments can be met if chip supply tightens, and whether token-metered revenue sustains its growth rate will define the first year of public life for the most valuable IPO ever priced.
