Anthropic Launches IPO Seeking Up to $64.4 Billion
Anthropic set an IPO price range of $70 to $78 per share in its second S-1 amendment, offering up to 825 million shares for a valuation of as much as $1.4 trillion and roughly $64.4 billion in proceeds, with about $62.5 billion flowing to the company via 801 million new shares. The filing also formally declares that Anthropic has crossed a Responsible Scaling Policy threshold where AI meaningfully accelerates AI research, a call based on expectations for future models rather than demonstrated current capabilities.

Anthropic again amended its S-1 today. Amendment No. 2
In its today's filing, Anthropic says it has crossed a line set in its Responsible Scaling Policy: the point where AI is making AI research much faster, which requires stronger safety checks.
A week earlier it said only that it “may imminently” cross it. The call is based on what it expects from future models, not on anything current models have shown. The filing also sets the IPO price at $70 to $78 a share.
↳ 引用 @rohanpaul_ai (Rohan Paul): Anthropic forges ahead with IPO roadshow They will sell up to 825M shares at $70 to $78 each, a range that values it at as much as $1.4T.
At the top of that range the deal raises about 62.5B from 801M new shares.
Existing stockholders are selling only 23.6M shares, so almost all the cash funds the company instead of letting early investors exit.
Earlier talk had pointed to as much as $2T, and the cut follows a tech selloff and midterm results showing voters souring on AI data centers.
Even reduced, the price sits above the $1.25T private valuation OpenAI reached last week.
Shares are expected to start trading on Nasdaq under the ticker “ANT” as soon as Thursday or Friday next week.
