Anthropic's internal AI use now costs more than its staff pay at retail prices: crossed over in April, 250x January by September

Anthropic's internal use of Claude, valued at the prices it charges customers, passed monthly employee compensation (excluding stock awards) in April and had grown more than 250-fold by September versus January.

Business Insider reported on Nov. 1 that Anthropic disclosed this in its IPO filing. It does not mean more cash goes to AI than to salaries; it is internal consumption valued at retail prices. Per the filing, more than 90% of code added to its software in September was written by Claude.

An amended filing on Nov. 2 added personnel figures. July–September personnel expenses for 5,300 employees topped $1.7 billion, $1.1 billion of it stock-based compensation, about $322,000 per person for the quarter. Nine-month personnel costs of $4.8 billion were 15% of revenue, versus more than twice revenue in 2023. Headcount is up 5x since the end of 2024. BI estimated revenue per employee at $6.6 million for Anthropic against $3.2 million at Meta and $2.5 million at Google. The filing says "talent density matters more than talent mass."

The story reached two of the top five posts on r/ClaudeAI on Nov. 3. One post's title says Anthropic spends more on "AI employees" than human ones, which differs from BI's retail-price caveat.

In a March piece BI wrote that tech companies are starting to treat AI tokens as a fourth component of pay, alongside salary, bonus and stock.
