What the S-1 shows
Anthropic's personnel expenses reached $3.152 billion in the first half of 2026, according to its SEC Form S-1 as reported by Crypto Briefing. That's a 486% increase over the same period a year earlier.
Most of it is equity. Stock-based compensation made up approximately 70% of personnel costs (around $2.2 billion), and headcount stood at approximately 5,300 employees as of September 30, 2026.
Revenue grew much faster
The cost line looks large on its own, but it's shrinking relative to sales. Anthropic reported revenue of $16.286 billion for the first half of 2026, up around 1,300% year over year, per Crypto Briefing's reading of the filing.
Personnel expenses fell to 19% of revenue in the first half of 2026, down from 46% a year earlier.
On a trailing-twelve-month basis, the company generated around $6.6 million in revenue per employee as of September 30, 2026, compared with $1.4 million a year prior. That's a very different efficiency picture than the quarterly headline suggests.
Compute is the bigger bill.
Anthropic spent $8.945 billion on compute and infrastructure in the first half of 2026, equal to 55% of revenue for the period and well above the $3.152 billion it spent on people.
The dilution question
Crypto Briefing said the personnel figures would likely draw scrutiny over dilution, arguing that roughly $2.2 billion in equity awards in a single half-year reduces shareholders' ownership with each grant. How much weight public-market investors put on that isn't something the filing answers.
Anthropic plans to list on Nasdaq under the ticker symbol ANT, according to the S-1 filed on October 26. For now, that's a plan disclosed in the filing, not a completed listing.
