Anthropic plans to sell up to $3.5B of IPO shares to Japanese investors
A Japanese securities filing dated November 2 shows Anthropic may sell up to 552.9 billion yen, about $3.5 billion, of newly issued shares to buyers in Japan as part of its planned US listing. Reuters, which reported the filing from Tokyo, says the proceeds will fund working capital, operating expenses and capital expenditure. Mizuho Securities will run the Japanese distribution, while Goldman Sachs and Morgan Stanley-linked brokers will take subscription applications. The filing does not state the total size or valuation of the offering, though some investors have discussed a figure near $1.5 trillion.
An amended S-1 published the same day adds third-quarter results. Revenue was about $17 billion, up roughly 47% from the second quarter, while total operating expenses rose to $17.5 billion. That turned a $974 million operating profit in the second quarter into an operating loss of $567 million. Anthropic attributes most of the swing to about $5.0 billion of short-term compute bought at higher prices than its multiyear deals. The quarterly net loss was $23.3 billion, mostly from an accounting charge tied to convertible notes.
Japan was already named in the October 26 registration statement, alongside Australia, Canada, parts of Europe, Switzerland and the UK. Japanese buyers took roughly $2.2 billion of SpaceX's June IPO, which raised $75 billion. Anthropic plans to trade on Nasdaq under the ticker ANT, and the Japan figure is a ceiling on value rather than a fixed share count.
Why it matters
For founders, the filing shows a frontier lab funding compute with public equity sized in billions. The amended S-1 discloses about $895 billion in compute and infrastructure commitments, with $69.8 billion falling due within a year. Compute absorbed about 58 cents of each third-quarter revenue dollar, up from 48 cents, so model-serving costs are now a public line item.
For investors and operators, the price set at pricing will become a reference point for private AI valuations, including secondary sales and future funding rounds. The disclosure also shows that short-term compute can cost more than multiyear commitments, so buyers of capacity need to plan contract length as carefully as unit price. Companies selling to or building on frontier labs should watch whether this margin pressure persists.
