Anthropic 撤回 IPO 定价文件，草案曾拟募资至多 693 亿美元

Reuters reported on November 10, 2026, that Anthropic sent banks a draft securities filing late on November 9, 2026, outlining an IPO that could raise up to $69.3 billion, before a follow-up email said the pricing details were inaccurate.

An Anthropic representative later said the company would update the filing. The follow-up did not identify which details were erroneous, Reuters could not determine what was incorrect, and Anthropic declined to comment. The pricing figures therefore cannot be treated as confirmed, and the second email provided no basis for determining whether other terms would change.

What the Retracted Draft Contained

The original email described 866.7 million Class A shares at $70 to $80 per share, including a secondary offering. Of that total, Anthropic would sell about 843.3 million shares and existing shareholders another 23.3 million. The top-end figure combined the company and shareholder sales, rather than measuring only the shares Anthropic itself would sell.

Separately, the retracted filing showed $26 billion in investments lined up alongside the IPO. Google, Nvidia, Advanced Micro Devices, Broadcom, Micron Technology, Microsoft, and TSMC had agreed to participate in a private placement of Anthropic’s Class N common stock at the IPO price, with closing immediately after the offering. The placement was distinct from the Class A share sale, making it a separate financing component rather than part of the IPO total.

Offering Timetable and Filing Status

A formal roadshow was expected on November 10, 2026, with pricing expected in the subsequent week. Both steps remained reported expectations rather than completed events or a company-confirmed timetable. Anthropic’s SEC submissions history listed an amended IPO registration filing dated November 2, 2026, as its latest public entry, with no later entry carrying the emailed draft.

Valuation Expectations and Capital Needs

The Reuters report placed the offering against delayed or withdrawn listings by other AI infrastructure and data-center companies, rising interest rates, and a selloff in shares and bonds of AI operators such as CoreWeave. The backdrop also included broader questions about whether AI spending was sustainable.

Investors had previously discussed an Anthropic valuation of as much as $2 trillion, but expectations had since fallen, with $1.5 trillion viewed as the high end of the range, the report said.

Anthropic had nearly $900 billion in computing commitments with partners including Amazon and Google. These commitments concerned future capacity, some reliant on financing outside Anthropic’s control. Both companies also occupied overlapping roles in Anthropic’s business, backing it financially while providing computing capacity and distribution even as their own AI efforts competed with Claude.

The report said revenue was almost $17 billion for the three months ended September 30, 2026, and that the quarterly growth rate had declined sharply. Those figures made the offering’s scale and terms important to Anthropic’s ability to finance future capacity.

Until the promised update arrives, the retracted draft shows the potential scale of Anthropic’s financing without establishing which pricing terms remain valid. That makes the update central to understanding how the proposed public share sale and separate private placement would support the company’s capital-intensive expansion.
