Anthropic's latest filing shows personnel expenses jumped 486% YoY to $3.152B for the first half, far outpacing compute's 283% growth; per compute dollar, staff spending rose from $0.23 to $0.35.
- Stock-based compensation drove the shift, climbing from $286M to $2.2B — about 70% of personnel expense. Excluding stock pay, personnel grew 3.8X, roughly in line with compute.
- Of the $9.741B first-half research spend, $3.2B was non-compute (after $6.6B of the $8.945B compute bill served customers) — closely matching the personnel bill, suggesting most staff costs go to research (author's estimate).
- Revenue rose 14X to $16.286B; trailing revenue per employee exceeds $6.6M, up from $1.4M.
- Key risk: employee shares vest fully only at IPO and aren't yet expensed, so the IPO quarter will see a sharp one-time spike in recorded staff costs.
