Anthropic Reportedly Plans $3.5 Billion Share Sale to Japanese Investors Before Nasdaq Listing

Mizuho is said to be leading the Japanese tranche as the AI company prepares for a US public offering.

Anthropic is reportedly preparing to raise as much as $3.5 billion from Japanese investors ahead of a planned listing on the Nasdaq exchange in the United States. The reports, published by CoinGape and Cryptopolitan on November 2, 2026, describe the transaction as a pre-IPO share sale rather than a traditional public offering tranche.

Mizuho is reportedly leading the Japanese portion of the deal, according to Cryptopolitan. The involvement of a major Japanese financial institution suggests Anthropic is seeking to broaden its investor base beyond US venture capital and institutional backers before going public.

Anthropic, the developer of the Claude family of large language models, has emerged as one of the most closely watched private companies in the artificial intelligence sector. The company competes directly with OpenAI and other firms racing to commercialize generative AI technology. A Nasdaq listing would give public market investors direct exposure to that competition for the first time.

Raising capital from Japanese investors ahead of a US listing is not unprecedented, but a sum of this size signals strong international demand for exposure to leading AI companies. Japanese financial institutions and conglomerates have increasingly sought stakes in US technology firms, viewing AI infrastructure and software as a long-term growth theme.

The reported structure, a private placement preceding a public listing, allows a company to lock in capital and investor commitments before the volatility of an IPO roadshow. It also lets select investors, in this case based in Japan, gain early access to shares that may otherwise be difficult to obtain once trading begins.

Neither CoinGape nor Cryptopolitan detailed the exact valuation Anthropic is targeting through this transaction, nor the specific timeline for the Nasdaq debut. Details such as pricing, share class, and the identities of additional underwriters beyond Mizuho were not fully specified in the available reporting.

The broader context matters for markets watching the intersection of traditional finance and emerging technology sectors, including crypto and blockchain infrastructure. Large AI firms going public often draw comparisons to how digital asset companies have approached public listings, given shared investor interest in high-growth, technology-driven businesses.

If the $3.5 billion figure holds, the Japanese tranche would represent a substantial share of Anthropic's overall pre-IPO fundraising efforts. It would also place Mizuho among the key financial institutions bridging Japanese capital with US technology listings in the current cycle.

Market Impact

A successful $3.5 billion raise from Japanese investors would reinforce the view that institutional appetite for AI exposure remains strong, even as public markets weigh high valuations across the sector. It could also encourage other US-based AI companies to pursue similar pre-IPO placements with Asian financial institutions before listing domestically.

For crypto and broader technology investors, the deal underscores how capital is flowing toward infrastructure-heavy AI firms ahead of public listings. A high-profile Nasdaq debut from Anthropic could also influence sentiment toward other technology IPOs expected in the coming months, including any tied to blockchain or digital asset infrastructure.

As Anthropic moves toward a potential Nasdaq listing, the reported Japanese share sale highlights growing cross-border interest in major AI companies. Further details on valuation, timing, and additional underwriters are expected as the IPO process advances.
