Anthropic seeks up to $3.5 billion from Japanese investors in IPO, Nikkei Asia reports

Anthropic is seeking to raise up to $3.5 billion from Japanese investors in an initial public offering, Nikkei Asia reports. The move highlights Japan's expanding role in financing advanced AI and raises the stakes in the race to fund large model development. It also signals Anthropic's push to diversify its capital base as it scales compute and global operations.

Nikkei Asia did not specify a listing venue, but said the company aims to attract significant participation from Japanese institutions as part of its IPO fundraising. Anthropic, the developer of the Claude AI system, has previously announced strategic investments and commitments from Amazon and Google to support model training and deployment. Watch for confirmation of the fundraising target, details on the listing venue and timetable, and which Japanese investors anchor the deal. [Developing. This article will be updated.]
