Artificial intelligence company Anthropic plans to sell up to 552.9 billion yen, equivalent to approximately $3.5 billion, worth of shares to investors in Japan as part of its planned US public listing, according to a filing reported by Reuters on November 2, 2026.
The filing states that the proceeds from the new shares issued to Japanese investors will be used to raise working capital and fund the company’s operating expenses and capital expenditure.
However, the document does not specify the overall size or valuation of Anthropic’s planned initial public offering (IPO). Reuters has previously reported that some investors have discussed a potential valuation of approximately $1.5 trillion for the company. This figure has not been confirmed as the final IPO valuation.
The proposed share offering highlights the participation of Japanese investors in major international public listings. Japan has increasingly become an important source of investment for companies preparing large-scale stock market offerings.
A recent example is SpaceX’s IPO in June 2026, described as the world’s largest public offering. Investors in Japan secured shares worth $2.2 billion out of the $75 billion raised through that listing.
Anthropic is among the major companies developing advanced artificial intelligence models and tools. Its planned public listing comes amid continued investor interest in the AI industry and the businesses building advanced AI systems.
The proposed $3.5 billion allocation in Japan forms part of the company’s broader listing plans. The filing provides details of the intended share sale but does not confirm the final IPO structure, timing or valuation.
The reported currency conversion is based on an exchange rate of $1 to 157.8200 yen.
