Anthropic reports nearly $17 billion in third-quarter revenue in an amended IPO filing and seeks up to $3.5 billion from Japanese investors
The updated prospectus adds third-quarter financials as the company prepares one of the largest listings in the AI sector.
Anthropic reported third-quarter revenue of nearly $17 billion in an amended prospectus for its initial public offering1. The company released the amended filing on Monday with its third-quarter financials included2.
Separately, Anthropic is seeking to raise up to $3.5 billion from Japanese investors as part of the IPO3. It plans a $3.5 billion share sale to investors in Japan as the US listing approaches4.
The filing did not disclose the overall size of the proposed offering or set a definitive valuation4.

Why it matters to investors
The amended prospectus gives public-market investors their first look at the company’s most recent quarter before the listing2. A revenue figure close to $17 billion for a single quarter sets the baseline against which any IPO price will be judged1.
The Japanese tranche matters for the structure of the deal. Allocating up to $3.5 billion to Japanese investors spreads demand beyond the US market3,4, which can matter for an offering of this scale at a time when AI stocks have been volatile.
The listing is also arriving into a nervous market. Stock futures rebounded on Monday ahead of a busy week of earnings, jobs data and the midterm elections, with Anthropic’s S-1 filing among the items investors were weighing5. One market participant said on Friday, “I just don’t see anything broken with the AI trade fundamentally”5.
Because the filing leaves both the offering size and the valuation open4, the revenue figure is for now the clearest hard number investors have1.
What to watch
The next milestones are the price range and the total size of the offering, neither of which the current filing establishes4. Those numbers will determine how the nearly $17 billion quarterly revenue figure translates into a valuation1.
The response from Japanese investors to a share sale of up to $3.5 billion will be an early read on international appetite3,4.
Investors will also look at how the amended prospectus treats the third quarter in detail, since it is the first filing to include those figures2.
Finally, the listing’s timing overlaps with a week of earnings, labour-market data and US midterm elections that could move risk appetite in either direction5. How AI shares trade through that week will shape the backdrop for the pricing1,5.
