Anthropic’s employee bill hit $1.7 billion in one quarter, or $107,000 per worker each month
The figures highlight the extraordinary cost of building an AI company as it races toward a potential $1.5 trillion IPO.
Anthropic is racing toward an IPO, and its latest prospectus update offers a revealing look at the extraordinary costs of building one of the world's most valuable AI companies. Alongside a 1,200% increase in revenue for the first nine months of 2026, to $33.24 billion, the company reported a 314% increase in its net loss, to $104.04 billion.
But beyond the headline financial results, the filing contains some striking details about what Anthropic spends on its employees, how much its founders receive, and the vast sums it is committing to computing infrastructure. Here are five of the most notable figures.
$106,920 a month. This is the average monthly compensation cost per Anthropic employee. The extraordinary packages offered to AI specialists by companies such as Anthropic, Meta and OpenAI are well documented. In recent years, competition for top talent has pushed total annual compensation, including salaries, stock and benefits, into the seven-figure range. In September, a researcher who had been recruited by Meta with a compensation package reportedly worth more than $1 billion left the company after just one year.
Anthropic's updated prospectus suggests that the enormous sums being spent on talent are not limited to a handful of headline-grabbing recruitment deals. The company reported $1.7 billion in employee compensation expenses in the third quarter, when it had 5,300 employees. Dividing the total by the workforce produces an average of approximately $320,750 per employee for the quarter, or $106,920 a month.
That does not mean that every employee, or even a significant proportion of the workforce, earns anything close to that amount. The figure is an average and may be skewed upward by exceptionally large compensation packages awarded to a relatively small number of senior employees and researchers. Still, it offers a striking indication of how much the company is spending to attract and retain talent.
$34.37 million. That is the combined value of the compensation, shares and other payments received by Anthropic's co-founders and executives, Dario and Daniela Amodei, in 2025. Leading one of the world's most closely watched AI companies clearly comes with substantial financial rewards.
Their base salaries were relatively modest by comparison, at $654,177 each. But both also received shares valued at $9.26 million and stock options worth $4.03 million. The main difference between their compensation packages was in the category of "other compensation": Dario received $4.01 million, while Daniela received $2.46 million.
Much of that additional compensation was related to security. Anthropic spent $2.75 million on security for Dario and $1.29 million for Daniela. The company also paid each of them $1.15 million to cover the difference between the purchase price and the market value of shares it repurchased from them.
Dario additionally received $97,100 in reimbursements for "private flights for personal use, as necessitated by his security requirements," including travel costs for guests accompanying him.
$3 billion a month. This is how much Anthropic pays Elon Musk's SpaceX under a short-term agreement for access to computing capacity at the company's data centers. The contract is one of several arrangements Anthropic has entered into to expand its available computing power immediately, even as it invests in building its own infrastructure through direct ownership, long-term leases and partnerships.
These external computing agreements weigh heavily on the company's operating costs. That pressure is expected to ease only as more of Anthropic's own infrastructure comes online.
$895.4 billion. This is the amount Anthropic expects to commit to AI infrastructure in the coming years, through agreements to purchase computing capacity and leases for computing power and physical infrastructure. The figure is equivalent to roughly half the company's projected IPO valuation, although its infrastructure commitments could grow further as its needs evolve. Of the total, $447.5 billion is scheduled to be spent by the end of 2030.
Anthropic is already investing heavily in computing capacity. In the third quarter alone, its spending on AI infrastructure rose 77% to $9.9 billion. Data centers accounted for 58% of the company's expenditures, up from 48% in the same quarter last year.
$1.5 trillion. The most consequential figure does not appear in the prospectus at all. According to reports by The Wall Street Journal and Reuters, this is the valuation that some investors are urging Anthropic to target for its IPO.
In recent months, reports have repeatedly suggested that Anthropic was aiming for a valuation of as much as $2 trillion, potentially surpassing SpaceX to become the largest public offering in history. But in recent days, several institutional investors have reportedly told the company and its advisers that they believe the offering should be priced at a valuation of between $1.5 trillion and $1.6 trillion.
The more cautious expectations come amid a volatile market, growing concerns about investors' exposure to AI stocks and a backlash in the United States against the rapid expansion of data centers. The latter issue is also emerging as a factor in the U.S. midterm elections. Their outcome could influence the administration's approach to investment in AI infrastructure over the next two years, potentially affecting the timing and pricing of Anthropic's IPO.
