Winners & losers: It's no secret that if you want some of the most lucrative compensation packages in tech, AI is the industry to be in. That's been perfectly illustrated by Anthropic's amended S-1 filing, which reveals its personnel costs recently averaged over $100,000 per employee per month.

The filing, spotted by Business Insider, shows that Anthropic recorded more than $1.7 billion in personnel expenses from July through to September. With 5,300 people working at the company, that works out at over $322,000 per person over the three-month span, or about $107,300 per employee per month.

Those costs include standard cash salaries along with bonuses, benefits, and employer payroll taxes. The largest share, $1.1 billion, came from Anthropic's stock-based compensation expenses, which reflect the value of company shares employees earn as part of their pay. Anthropic records that value as an expense even though employees don't receive the equivalent amount in cash.
