Anthropic Faces Rising AI Infrastructure Costs Despite Strong Revenue Growth

Staff Reporter | PNN

Artificial intelligence company Anthropic has disclosed more detailed information about its financial position as it prepares for a potential stock market listing.

Newly released documents show that although the company's revenue is growing rapidly, its expenditure on computing and AI infrastructure is increasing even faster.

As a result, the company's operating margin has come under pressure.

In an updated filing published on Monday, Anthropic included financial information for the three months ending September 30 of this year.

An earlier preliminary filing published the previous week contained financial figures up to the end of June.

According to the latest information, the company's revenue reached $17 billion in the third quarter, compared with $11.5 billion in the previous quarter.

However, its operating losses also increased during the same period, largely due to rising computing expenses.

According to the filing, computing costs accounted for 58 per cent of total revenue in the third quarter.

The figure had stood at 48 per cent in the previous quarter.

This means that despite the increase in revenue, pressure from computing expenses has not eased. Instead, the proportion of revenue spent on computing has increased at a time when the company is preparing for an initial public offering (IPO).

The financial charts included in the report also illustrate this trend.

Since the beginning of 2025, revenue generated for every dollar spent on computing had been steadily increasing.

In the third quarter of this year, the figure briefly climbed to slightly above $2 before falling to $1.72.

Rapidly growing demand for Anthropic's services is considered one of the major reasons behind the increase in expenses.

During the third quarter, the company's total computing bill reached $10 billion.

Of this amount, $5 billion worth of computing capacity was obtained through short-term agreements.

The company's filing stated that expenses under these agreements were significantly higher than the costs of obtaining similar computing capacity through multi-year contracts.

As Anthropic attempts to secure additional computing capacity quickly to meet rising demand, it is being forced to purchase services at higher prices.

These arrangements include a $1.25 billion-per-month computing agreement with SpaceX, as well as multi-billion-dollar agreements with Nscale, Akamai and Vultr.

These companies are often described as 'neocloud' providers in the AI industry.

They generally offer computing capacity through relatively smaller and more flexible contracts, although such services can come at a higher cost.

Anthropic is attempting to reduce expenses by expanding its own computing capabilities.

To achieve this goal, the company has announced an initiative called 'Anthropic Direct'.

However, given the pace at which demand is increasing, managing all of its requirements through its own infrastructure could prove difficult.

As a result, the company is likely to remain dependent on external computing providers, at least for the time being.

Anthropic's filing stated that infrastructure and computing expenses would continue to increase in the coming days and would remain the largest component of its operating costs.

The company also plans to make further investments in computing capacity while adding new resources through multi-year agreements.

With revenue growing rapidly, these expenses may not yet represent a major concern for investors.

However, if infrastructure expansion slows due to delays in data centre construction, rising financing costs or local opposition, AI companies such as Anthropic could face increasing pressure.

The company's future growth will therefore depend not only on demand for its services but also on the availability and cost of computing capacity.
