Anthropic’s Q3 personnel costs topped $1.7 billion ahead of IPO
Anthropic’s amended IPO filing reported more than $1.7 billion in personnel expenses for 5,300 employees from July through September, averaging over $322,000 per worker for the quarter. Stock-based compensation made up $1.1 billion of the total, underscoring how heavily the company’s reported costs reflect employee equity as it approaches a public listing.1
TL;DR
- The headline personnel figure is not equivalent to cash wages: stock-based compensation accounted for most of the quarter’s expense.1
- Prediction-market expectations cluster in the $1.5 trillion to $1.75 trillion IPO valuation band, while reporting has described a broader possible range and the filing has not set a price.23M3
Still to come
- Anthropic is expected to list later this month, but its amended filing did not disclose the share price or how much it plans to raise. The final IPO terms will establish the valuation against which the reported expectations can be measured.
The expense total includes salaries and bonuses, benefits, employer payroll taxes and stock-based compensation. That last category was the largest component in the quarter, at $1.1 billion. Anthropic said it had more than $32 billion in stock-based compensation expenses not yet included in its accounting as of the end of September, and the filing said a successful listing would increase personnel costs in coming quarters.1
The costs are rising alongside fast-growing revenue: personnel expenses totaled $4.8 billion in the first nine months of 2026, or 15% of revenue over that period, according to the filing. Anthropic reported third-quarter revenue of $17 billion but a net loss of $23.3 billion; it has also committed about $895.4 billion to computing and infrastructure, including $70 billion due over the next 12 months. The figures frame the IPO around both the scale of the business and the substantial costs and obligations behind its growth.12
The IPO valuation remains uncertain. Several media outlets have reported a possible valuation of $1.5 trillion to $2 trillion, but the amended filing gave no share price or fundraising target. On November 2, prediction-market pricing implied about a 69% probability that the IPO valuation will fall between $1.5 trillion and $1.75 trillion, a narrower range that shows where market expectations are concentrated without resolving the final price.23M3
