Anthropic spent $1.60 on compute for each dollar of 2025 revenue, prospectus shows

Anthropic's IPO prospectus, seen by Reuters, shows $7.33B of 2025 compute spending against $4.59B of revenue and $518B in forward infrastructure obligations. For teams building on Claude, today's prices and capacity terms rest on a cost base the company still runs at an operating loss.

What happened

  • Anthropic's 2025 operating loss was $8.06B, up from $2.98B in 2024, while revenue grew roughly 12x from $386M the year before.
  • About $34B of the reported $41.97B GAAP net loss is an accounting charge on financing instruments that could convert into shares and rose with the company's value.
  • Nearly a quarter of Anthropic's 2025 revenue came from just two customers, according to RuntimeWire's account of the prospectus.
  • Anthropic submitted a confidential draft S-1 on June 1, and Reuters reported that a public debut is likely after the November midterm elections.

Why it matters

  • Who has to decide decision A team pricing its product on current Claude rates is relying on terms set by a vendor that spent more on compute than it earned in 2025, so those rates belong in the plan as variables.
  • What it limits constraint Anthropic carries decade-long supply contracts against large customers with no long-term contract holding them, and the terms it controls to close that gap, price and commitment length, both fall on buyers.
  • What doesn't add up contradiction The two reports disagree on whether the $518B lands in the coming year or over time, and that schedule sets how much pressure the obligations put on near-term pricing.

The reported figures reconcile. Revenue of $4.59B [1] minus $12.65B of operating expenses [5] matches the $8.06B operating loss [13]. Compute and infrastructure took $7.33B of those expenses. That is nearly triple the prior year and about 58% of the total [4][5]. Divided by revenue, it comes to roughly $1.60 of compute for every dollar earned [14].

The $1.60 is a company-wide ratio. For it to mean Claude is sold below cost, most of the $7.33B would have to be inference, the capacity that answers requests. The same line also pays for training. The Neuron notes that better models need larger training runs and more customers need more inference capacity [23]. The reported figures do not split the two, and they do not cover API pricing. If training is the larger share, serving can carry a margin while the company as a whole still loses money on operations [9].

The forward commitments are harder to read. Anthropic committed more than $100B over ten years to AWS for up to 5 GW of capacity [21]. Separately, it expanded its Google and Broadcom relationship for multiple gigawatts [22]. The AWS deal alone averages more than $10B a year, above the entire 2025 compute and infrastructure line [24]. The roughly $518B in cloud, compute and infrastructure obligations [6] is about 71 times 2025 compute spending [15]. It is also roughly 25 times year-end cash and short-term investments [16].

The two reports disagree on when that money is owed. RuntimeWire describes obligations Anthropic "plans to take on in the coming year" [18]. The Neuron calls them "forward commitments associated with the infrastructure Anthropic expects to need over time" [19]. RuntimeWire adds that how quickly the commitments fall due will matter to investors [20].

The demand side runs on shorter terms. According to RuntimeWire, Anthropic's risk factors warn that many large clients could reduce or end spending because they are not bound by long-term contracts [8]. In my view, a supplier holding decade-long costs against revenue that can walk will reach first for the terms it controls. Those are price and commitment length.

For a product whose gross margin moves with token price, I think current Claude rates and rate limits belong in the plan as provisional. The vendor setting them runs at an operating loss [9]. Year-end cash covers about two and a half years of the 2025 loss, though an operating loss is not the same as cash burn [17]. Reuters reported the listing could value Anthropic above $2 trillion, more than twice its $965B post-money valuation from May [10].

What to watch

  • Whether the public S-1 gives a payment schedule for the $518B in obligations, and how much of it falls due in 2026.
  • Any split of the $7.33B compute line between training and inference, or a gross margin on API revenue.
  • Changes to Claude API pricing, rate limits or committed-spend contract terms ahead of a listing Reuters expects after the November midterms.
