Anthropic IPO draws heavy orders as Japan sale targets up to $3.5 billion
Anthropic’s IPO has reportedly attracted orders multiple times the available shares. Its planned $3 billion–$3.5 billion Japanese allocation would exceed Japan’s reported domestic IPO proceeds so far this year, but indications of interest are not completed sales.
- Anthropic’s IPO has reportedly drawn orders multiple times the shares available, led by large indications of interest.
- Japan’s planned allocation is $3 billion–$3.5 billion, through a sale that does not require a Japanese exchange listing.
- The reported $64.4 billion IPO target excludes the private placement included in a separate $90.4 billion figure.
Anthropic, the US artificial-intelligence developer behind the Claude chatbot, has attracted orders multiple times the shares available in its initial public offering, according to a report citing people familiar with the matter. The demand was driven by large, “anchor-size” indications of interest, the people said. That is evidence of appetite during the offering process, rather than a completed fundraising result.
The Japanese portion shows how consequential even one national allocation could be. Documents released on November 11 put the planned sale there at $3 billion–$3.5 billion, or approximately ¥473.9 billion–¥552.9 billion, according to a report on the offering terms. That is roughly 1.8–2.0 times the approximately ¥270 billion raised through domestic Japanese IPOs priced so far this year, using the report’s yen figures.
The comparison captures the allocation’s scale, with an important boundary: this is Japanese participation in a US IPO, rather than proceeds from a new listing on a Japanese exchange.

The Japan sale uses POWL, a mechanism for offering shares to domestic investors without listing them on a Japanese exchange. The November 11 documents envisage roughly 38.46 million–50 million shares for Japanese investors and an indicative price range of $70–$78 a share. Anthropic said on November 2 that it planned to raise up to $3.5 billion in Japan, according to an earlier account of the company’s plans.
