Anthropic reported about 5,300 employees on Sept. 30 as revenue per employee topped $6.6 million over the prior 12 months, its registration filing showed. The figure is a companywide measure and does not represent individual employee compensation.
The ratio stood at $1.4 million for the 12 months ending Sept. 30, 2025. Anthropic’s workforce grew from roughly 940 people at the end of 2024 to about 5,300 on Sept. 30, 2026, an increase of roughly 5.6 times.
Separately, the filing reported $16.286 billion in revenue for the six months ended June 30, 2026, compared with $1.163 billion in the first half of 2025. Anthropic said a series of model and product launches expanded customer use across its offerings. The six-month revenue figure covers a different period from the trailing 12-month measure.
Personnel expenses totaled $3.152 billion in the first half, a 486% year-over-year increase. Anthropic linked a $1.9 billion rise in stock-based compensation and a $510 million increase in cash compensation to headcount growth. The filing also reported $8.945 billion in compute and infrastructure expenses for the period.
