Update: Anthropic amends its IPO filing and shows $17 billion in third-quarter revenue, up more than 1,100% in a year

The amended prospectus (S-1/A) Anthropic filed with the SEC on Monday brings the third-quarter numbers: revenue of $16.96 billion, about 1,127% above the same period of 2025 and about 47% above the previous quarter. Over nine months, revenue totals $33.24 billion. The company had an operating loss of $567 million in the quarter, after an operating profit of $974 million in the second; according to Business Insider, the swing came mainly from $5 billion in short-term contracted compute. The net loss was $23.29 billion in the quarter and about $104 billion over nine months, mostly from the change in the value of convertible notes. Purchase and lease commitments reach about $895.4 billion, almost all in compute. The document still has no price range; according to Reuters, investors talk of valuing the company at about $1.5 trillion, and a filing in Japan plans to sell up to 552.9 billion yen (about $3.5 billion) in shares to Japanese investors, led by Mizuho.
