Anthropic Seeks to Sell Billions of Shares in Japan. An Expert Explains Why The IPO Boom Needs Global Money.

Anthropic's plan to sell up to $3.5 billion in shares to Japanese investors shows how the artificial intelligence financing race is pushing companies beyond Wall Street to find buyers for increasingly large offerings.

The Claude developer disclosed the proposed Japanese sale in a filing Monday as part of its planned U.S. initial public offering. Proceeds would support working capital, operating expenses and capital investment. The filing did not establish the overall IPO's size or valuation.

For Patrick Boyle, a visiting finance lecturer at Queen Mary University of London and King's College London, and founder of Palomar Capital Management, the overseas push reflects the competing demands on investors financing the technology industry.

"A deal this size can't rely on U.S. institutions alone," Boyle said. U.S. institutions, he added, are "already stretched across the big tech companies' other fundraising." That makes distribution a central part of the transaction.

Investment banks must locate prospective buyers across markets rather than assume domestic institutions will supply all the necessary money. "Japan is an obvious place to look," Boyle said. "It's one of the largest pools of growth-hungry savings in the world, Japanese households and institutions have been big international investors for decades."

"AI is the most sought-after growth story on the planet, so there's natural appetite there." Mizuho Securities will manage Anthropic's Japanese share sale. Goldman Sachs, Mitsubishi UFJ Morgan Stanley Securities and Morgan Stanley MUFG Securities are among the firms handling applications.

The proposed allocation follows another major test of Japanese demand for an American technology offering. Investors in Japan received $2.2 billion in shares in SpaceX's June IPO, which raised $75 billion overall. "International issuance has become the standard playbook for the hottest mega-IPOs," Boyle said.

SpaceX also offered a model for reaching individual investors through local financial intermediaries. Boyle sees Anthropic's Japanese distribution strategy as an extension of that approach. "When you need this much capital, you tap every deep pool of savings you can reach, and you use a local intermediary to get to the retail investors in each market," he said.

The fundraising comes with substantial spending needs. Anthropic's updated IPO filing showed $17 billion in quarterly revenue and a $23.3 billion quarterly net loss. The company also disclosed $895.4 billion in computing and infrastructure commitments, including $70 billion due over the next 12 months.

Boyle said the same search for a broader investor base is visible in technology companies' borrowing across currencies and markets. "You see the same pattern in the bond market," he said.

His comparison distinguishes two routes to financing the expansion: borrowing from creditors and selling ownership stakes to shareholders. In both cases, his argument is that the scale of demand for money encourages companies to widen their reach. "Anthropic's Japan share sale is the equity version of the same logic: when the sums are this big, you go to every deep pool of capital you can reach."
