Anthropic cuts Japan share offering target to $3 billion

Anthropic has lowered the amount it hopes to raise from Japanese investors in its upcoming IPO. The Claude developer now targets $3 billion from its Japan tranche, down from an earlier goal of up to $3.5 billion.

Even after the trim, the Japanese slice is still expected to be the largest offering ever by a foreign company in Japan.

What changed in the Japan tranche

Anthropic PBC first filed documents for the Japanese portion of its offering on November 2, 2026. That filing sought up to $3.5 billion, or ¥552.9 billion, from investors in Japan.

An updated prospectus followed on November 10. That update brought the Japan-specific target down to $3 billion.

The same November 10 update set the overall IPO price range at $70 to $78 per share. Anthropic plans to offer 825 million Class A shares within that range.

At the top of the range, gross proceeds could reach up to approximately $64.4 billion. The implied valuation at that upper bound stands at approximately $1.4 trillion.

On top of the public offering, Anthropic has lined up a $26 billion private placement from strategic investors, including Google and Nvidia.

How the Japanese offering works

The Japan portion is being handled by a roster of brokers that includes Mizuho Securities and Goldman Sachs. The deal is aimed predominantly at institutional investors.

Retail investors are not shut out entirely. Individual allocations are set to be handled through a lottery mechanism, which means demand from everyday buyers may outstrip what they actually receive.

Proceeds from the newly issued shares are earmarked for working capital, operating expenses, and capital expenditures.

Anthropic expects to list under the ticker “ANT.” Trading is anticipated to begin in mid-to-late November 2026, with November 19 cited as the likely start date.

The road to the listing

The IPO process formally kicked off when Anthropic filed its S-1 registration statement with the US Securities and Exchange Commission on October 26, 2026. The Japan filing came about a week later.

Japan has recently become a notable venue for foreign tech listings. SpaceX raised $2.2 billion from its Japanese IPO in June 2026, which stands as the current record for a foreign company in that market.

Anthropic’s revised $3 billion target would still clear that mark comfortably.

What the revision signals

For investors in Japan, the practical effect is fewer dollars available through the local tranche. Combined with a lottery for retail allocations, that could make shares harder for individuals to secure at the offering price.

Investors will be watching where the final price lands within the $70 to $78 range. A pricing near the top would suggest demand held up despite the Japan trim, while a pricing near the bottom would raise questions about appetite at this valuation.
