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 today, Nikkei Asia reports. A push to tap Japan’s capital base signals how the Claude maker is broadening funding sources amid a costly buildout of AI infrastructure, including data center capacity and advanced chips. The move underscores intensifying global interest in generative AI investment and could deepen ties between Silicon Valley and Tokyo markets as Japanese institutions seek exposure to foundational model developers.

Further details on listing venue, timing, prospective underwriters, and allocation were not immediately available, and the company, founded by former OpenAI researchers and backed by Amazon and Google, is now courting Japanese institutional demand, according to Nikkei Asia. Watch for clarity on listing venue, valuation range, cornerstone investors in Japan, and a filing timeline. [Developing. This article will be updated.]
