Anthropic discloses $895 billion in compute commitments as it updates its IPO filing

A $895 billion bill

Anthropic put a total price tag on its computing ambitions for the first time on Monday. An amended S-1 filing lists about $895 billion of aggregate spending commitments, nearly all of it for computing and data centers, according to Yahoo Finance. About $70 billion of that comes due within a year, and the full bill is almost seven times the roughly $132 billion of cash and short-term investments Anthropic held at the end of September.

The scale of the number is worth sitting with. $895 billion is more than the entire annual GDP of many countries, and it dwarfs the amounts OpenAI and other rivals have publicly disclosed in filings. Anthropic has said its "Anthropic Direct" effort is building its own compute base, but it has repeatedly acknowledged that direct ownership alone cannot cover its needs, which is why the neocloud and CSP deals dominate the commitment list. The amended filing makes the balance of that strategy transparent for the first time.

Silicon UK reported the same number in more precise form: $895.4 billion in purchase commitments and lease agreements for computing power and infrastructure, of which $447.5 billion is expected to be incurred before the end of 2030. Anthropic is one of the biggest customers the cloud giants have, and one of their rivals too. As Evercore ISI analyst Mark Mahaney wrote after the first filing, "For the hyperscalers, Anthropic is at once a customer, competitor, sales channel and investment."

The disclosure follows earlier signed-up capacity. Anthropic has been paying SpaceX $1.25 billion a month for compute, alongside multi-billion dollar deals with Nscale, Akamai and Volta, TechCrunch reported. In the new filing, SpaceX's AI unit appears as a commitment of up to $120.5 billion, behind Google at about $121 billion and Broadcom at roughly $161 billion in equipment leases. Amazon rounds out the top tier at $110 billion.

Purchase commitments alone jumped to about $314 billion from $55 billion at the end of 2025, Yahoo Finance said, and Anthropic also plans another $125 billion to $150 billion of Google chips and expects to spend more than $20 billion with AMD. Neither of those deals has a fixed dollar commitment, so neither counts toward the $895 billion.

Profits lasted one quarter

The filing also added third-quarter results, extending the financials from June 30 to September 30, 2026. Revenue jumped to about $17 billion from $11.6 billion in the second quarter, up roughly 50 percent, according to Yahoo Finance and Silicon UK. That is a markedly slower growth rate than the 144 percent quarter-over-quarter pace Anthropic reported in Q2.

But Anthropic's first operating profit lasted just one quarter. The company reported a $567 million operating loss in Q3, one quarter after an operating profit of $974 million, driven primarily by an additional $4.3 billion in computing costs, Silicon UK reported. A $2 billion non-cash charge tied to a donation-matching program added to the loss, Yahoo Finance said.

The margin picture for compute got worse, not better. In the new quarter, compute took up 58 percent of revenue, up from 48 percent the quarter before, TechCrunch reported. Demand outran the capacity Anthropic books 12 to 18 months ahead, so it bought about $5 billion of short-term computing that, in the filing's words, "currently costs significantly more than comparable compute procured under our multi-year commitments." The company's spending on chips, power and other infrastructure jumped 77 percent from $5.6 billion to $9.9 billion.

What the filing says next

Anthropic's own filing frames the pressure as ongoing: "We expect compute and infrastructure expenses to increase in absolute dollars and remain our largest operating expense for the foreseeable future as additional committed compute becomes available to us under multi-year arrangements with CSPs, and as we continue to invest in additional compute." Its response is a project called Anthropic Direct, its own effort to build a compute base, but TechCrunch notes those efforts are not going to keep pace with demand, and neoclouds remain the best option.

The net loss picture improved on paper. The company's net loss fell to $23.29 billion from $66 billion in the previous quarter, though much of that swing reflects the one-off charges and revenue growth in the period, Silicon UK said.

Anthropic also disclosed that it estimates 5 percent to 7 percent of its revenue in the first nine months of the year came from customers who were breaking its usage policy or commercial terms. It stepped up enforcement in August and September and warned the crackdown "may reduce our overall revenue and growth rates in future periods," Yahoo Finance reported.

The company is expected to begin marketing its shares to potential investors next week, with a market value that could range from $1.5 trillion to $2 trillion, Silicon UK reported. Seaport Research Partners analyst Jay Goldberg cautioned on Yahoo Finance before the filing that the profitability would not last: "They will be profitable probably in the next quarter or two. But then they're going to start going back into losses."

Yahoo Finance's reading of the filing also flagged the policy-violation disclosure: Anthropic estimates 5 to 7 percent of its revenue in the first nine months of the year came from customers who were breaking its usage policy or commercial terms. It stepped up enforcement in August and September, and warned that the crackdown may reduce overall revenue and growth rates in future periods. For investors, that is a double-edged signal: it shows a commitment to policy enforcement, but it also admits a measurable slice of current revenue came from users the company was actively cutting off.

Why it matters

The $895 billion figure is the clearest public statement yet of how much money a single frontier lab has committed to the physical infrastructure of AI. It also shows how exposed the business remains to compute prices: revenue for every dollar spent on compute peaked at just over 2x this past quarter, then fell back to 1.72x, per TechCrunch's reading of a chart in the filing.

That mix matters for the IPO. Investors weighing Anthropic's listing will see a company with durable revenue growth, a widening operating loss driven by compute, and a balance sheet already carrying hundreds of billions in forward commitments. The market value range of $1.5 trillion to $2 trillion puts a premium on the growth story continuing, and there is little room for a slowdown in the data center buildout or a spike in local opposition that stalls new capacity.
