Anthropic Amended S-1: $17.0B Q3 Revenue, Compute at 58% of Revenue, and About $895.4B in Committed Compute and Infrastructure Spend
Amendment No. 1 to the S-1 that Anthropic filed with the SEC on November 2 adds its first Q3 2026 numbers. Quarterly revenue was $16.956B, up 1,127% year over year and about 47% above Q2 revenue of $11.555B. Compute and infrastructure expense was $9.863B, or 58% of revenue versus 48% in Q2, including $5.0B of pricier short-term compute. Q3 swung to a $567M operating loss from $974M of operating income in Q2; a $21.9B fair-value charge on convertible notes and similar instruments drove a $23.29B net loss. Anthropic also discloses about $895.4B of purchase commitments and leases, substantially all for compute and infrastructure.
Key Takeaways
- Q3 revenue was $16.956B, up 1,127% year over year and about 47% over Q2 revenue of $11.555B; nine-month revenue reached $33.2B
- Compute and infrastructure expense hit $9.863B, rising to 58% of revenue from 48% in Q2, including $5.0B of short-term compute that costs far more than multi-year capacity
- Q3 operating loss was $567M versus $974M of operating income in Q2; the $23.29B net loss is driven mainly by a $21.9B fair-value change on convertible notes and similar instruments
- Committed compute and infrastructure spend is about $895.4B: roughly $447.5B expected before the end of 2030 and about $69.8B due in the next 12 months
- Anthropic says it does not expect revenue to keep growing at comparable rates; headcount is about 5,300 and more than 1,900 customers pay $1M or more on a TTM basis
