Anthropic's draft S-1 shows $16.3B first-half revenue and an $80.7B net loss

#What happened

Anthropic's draft IPO prospectus (S-1), reviewed by The Wall Street Journal on Oct 20 and covered by Seoul Economic Daily (Reuters-Yonhap) on Oct 22, shows the Claude maker generated $16.3 billion in revenue in the first half of 2026, up sharply from $1.1 billion a year earlier. Over the same period it posted an $80.7 billion net loss, versus about $13 billion a year earlier (per Reuters via The Boston Report). About $72 billion of the loss was a non-cash accounting charge linked to convertible notes and financing instruments that grow in value as Anthropic's valuation climbs — not cash spent running the business. Compute and infrastructure spending came to nearly $9 billion in the half, up from $2.3 billion a year prior. The draft also locks in about $450 billion in cloud commitments over seven to ten years (roughly $111B Google, $110B AWS, $31B Microsoft, per MarketFlux), with talks underway that could push total compute obligations toward $750 billion. The filing is confidential and still a draft; Anthropic declined to comment and the numbers may change before a public filing.

#Why it matters

The numbers land weeks before a planned mid-November IPO reportedly targeting about a $2 trillion valuation (per Reuters via Investing.com). They are among the largest half-year corporate losses ever reported — yet Q3 reportedly turned in $16.8 billion of revenue with adjusted profitability and positive cash flow, and the company has logged two straight quarters of adjusted operating profit. The tension between the accounting loss and the improving operating trend is what the public market will judge when the S-1 unseals. Verified Oct 22, 2026.
