Anthropic IPO: What Does the S-1 Actually Show?
In short: Anthropic filed its S-1 with the SEC on 26 October 2026 (ticker ANT). The headline $80.7 billion loss for the first half of 2026 is mostly a non-cash charge on convertible notes; the real operating loss was $693 million, and the second quarter brought the first operating profit, $974 million. The biggest risk is about $637 billion of compute contracts, largely with Amazon, Google and Microsoft.
1. The $80.7B loss is mostly a paper loss
About $72 billion of the reported loss is a fair-value change on convertible notes. These notes are marked to current value, so the more valuable Anthropic becomes, the bigger the reported loss. Strip that out and the operating loss for the half-year was $693 million.
2. Revenue went from $41M to $16.3B in three years
$41 million in 2023, $386 million in 2024, $4.6 billion in 2025 and $16.3 billion in the first half of 2026 alone. The filing lists more than 11,900 customers paying at least $100,000 a year.
3. Compute cost per dollar of revenue fell from $2.00 to $0.48
In the first half of 2025 Anthropic spent about $2 on compute for every $1 of revenue; by the second quarter of 2026 it was 48 cents. That drove the first operating profit: $974 million in Q2 2026.
4. Net revenue retention of about 900%
The average existing customer pays about nine times more than a year earlier. A strong software company is usually around 120%.
5. The risks in the filing
About $895 billion of purchase commitments in the amended S-1, mostly compute and data centres with Amazon, Google and Microsoft, who are also competitors (the first filing showed about $637 billion). Q3 2026 revenue was $17.0 billion. The top five customers make up about 25% of revenue, and the seven co-founders keep 50.1% of the votes through a special share class.
