Anthropic IPO filing: $1.7B quarterly payroll, about $107K per employee monthly

Anthropic's S-1 IPO filing reveals the company spent $1.7 billion on personnel expenses in Q3 2026, averaging $107,300 per employee monthly when including salaries, bonuses, benefits, and stock-based compensation. While personnel costs represented over 200% of revenue in 2023, they now account for just 15% of the company's $33.2 billion in revenue through the first nine months of 2026, though an IPO completion could trigger an $8.2 billion stock-based compensation charge for restricted stock units.
