Anthropic discloses personnel bill topping US$1.7 billion for quarter
An amended IPO filing puts share-based compensation at US$1.1 billion, with further expenses potentially tied to a public listing.
Anthropic spent more than US$1.7 billion on its workforce during the July–September period, according to its amended S-1 filing. Stock-based compensation contributed US$1.1 billion, making it the biggest expense category within the personnel bill.
The AI company's 5,300-person workforce meant monthly personnel expenses averaged about US$107,300 per employee. That figure does not represent cash salaries alone: it also includes bonuses, benefits, employer payroll taxes and the accounting value of shares earned by employees.
A public listing could bring an additional accounting expense. Certain restricted stock units have two requirements: employees must remain with Anthropic for a specified period, and a qualifying event such as an IPO must occur.
According to Anthropic, completing an IPO on September 30, 2026, would have required it to book US$8.2 billion in compensation expense for those units that day. It also expected a further US$24.1 billion expense associated with the awards, recognized over approximately two years on a weighted-average basis.
For 2026's first nine months, Anthropic reported US$4.86 billion in personnel expenses and US$33.2 billion in revenue. The Claude developer's headcount has increased fivefold from its level at the end of 2024.
