Financials disclosed via Amazon's SEC filing reveal Anthropic's cost structure:
- Personnel expenses rose 486% YoY to $3.152B, far outpacing the 283% jump in compute spend.
- Staff cost per compute dollar climbed from $0.23 to $0.35.
- Stock-based compensation drove most of the shift, climbing from $286M to $2.2B — roughly 70% of personnel expense.
- Excluding stock pay, personnel costs still grew about 3.8x.
The takeaway: talent competition, not compute, is becoming the steepest cost curve for frontier AI labs.
