Anthropic Files IPO Terms: 825M Shares at $70–$78 Plus $26B Chip Backer Placement

Anthropic filed amended initial public offering terms on November 10, 2026, covering 825 million Class A shares at an estimated $70 to $78 each, alongside a contingent $26 billion private placement with seven chip and cloud giants. At the $78 top end, the base offering would generate $64.35 billion in gross proceeds, per the filing's stated share count multiplied by that price.

Anthropic itself is selling 801,351,354 shares; selling stockholders are offering another 23,648,646, and Anthropic receives no proceeds from the secondary sales. The company's primary portion would raise approximately $62.5 billion before underwriting discounts and expenses. Underwriters hold an option to buy up to 123,750,000 additional shares from Anthropic at the IPO price less the underwriting discount.

Anthropic has applied to list the Class A shares on the Nasdaq Global Select Market under the symbol ANT. The prospectus remains preliminary — terms may change, and no securities can be sold until the registration statement becomes effective.

What happened to the earlier draft?

Reuters reported on November 10, 2026, that a prior draft sent to banks proposed roughly 866.7 million shares at $70 to $80. Anthropic then sent a follow-up saying the pricing details were inaccurate and that it would update the filing.

Who is buying the $26 billion private placement?

Advanced Micro Devices, Broadcom, Google, Micron Technology, Microsoft, NVIDIA and TSMC Partners agreed, severally and not jointly, to purchase an aggregate $26 billion of Class N stock at the IPO price. The placement depends on the IPO's completion and other conditions, and it's scheduled to close immediately afterward — with no underwriting discount or commission on those shares.

The Class N shares aren't registered in the IPO and aren't covered by the underwriters' lock-up agreements. They're restricted securities, so resale requires an effective registration statement or an available exemption. Separately, certain directors and affiliated entities indicated interest in buying up to $303 million of IPO shares. Those indications are nonbinding and permit more, fewer or no purchases.

How fast is revenue actually growing?

Anthropic reported $17.0 billion of revenue for the three months ended September 30, 2026 — up 1,127% year over year. Compute and infrastructure expenses grew 382% over the same period, and the company presented that disparity as evidence of compute efficiency.

The customer base shows where the money comes from:

• More than 11,900 customers generated at least $100,000 in trailing-12-month revenue as of September 30, 2026
• More than 1,900 generated at least $1 million
• Approximately 250 generated at least $10 million

Anthropic uses the $100,000 tier as its measure of enterprise adoption, because spending at that level generally reflects organizational rather than individual usage.

What do the infrastructure commitments look like?

Anthropic's purchase commitments and lease agreements total approximately $900.9 billion, substantially all related to compute and infrastructure. That figure covers commitments in place on September 30, 2026, others entered into afterward, and leases not yet commenced.

The filing expects approximately $451.6 billion of the commitments to be incurred before December 31, 2030, with substantially all of the remainder falling between 2031 and 2045. Approximately $70.7 billion comes due in the 12 months after September 30, 2026.

Anthropic held $95.6 billion in cash and cash equivalents plus $36.3 billion in short-term investments as of September 30, 2026. It had raised $141.1 billion in aggregate capital by that date.

Who controls the company after the IPO?

Anthropic is a Delaware public benefit corporation, so its board must balance stockholders' financial interests, the interests of those materially affected by its conduct, and a charter purpose of maintaining and developing advanced AI responsibly for humanity's long-term benefit.

Through Class T stock, the Long-Tenefit Trust can generally elect and remove the Class T directors, who will constitute a majority of the authorized board. That stock carries no economic rights and no general stockholder voting rights.

Immediately before the offering completes, Anthropic will issue one Class F share to a limited liability company organized by its co-founders, giving it 50.1% of aggregate voting power on general stockholder matters — including elections of directors other than the Class T directors — but no economic rights. Anthropic qualifies as a controlled company under Nasdaq's governance rules because the Trust can generally elect a board majority.

Class N shares, including those in the private placement, generally lack voting rights and convert into Class A shares upon sale or transfer to an unaffiliated third party. The consequence is a clear division: public investors would bear the economic exposure to Anthropic's growth and its $900.9 billion in infrastructure commitments, while board appointments and general voting control stay with the Trust and the founder vehicle.
