Anthropic takes $518 billion of compute obligations to the IPO market on $4.6 billion of revenue

Anthropic spent $7.33 billion on compute and infrastructure in 2025, more than triple what it spent in 2024, according to Reuters' review of the prospectus as reported by Calcalist ^[2]. That was about 58% of its operating costs, with everything else coming to about $5.32 billion ^[2][7]. Measured against that base, the $518 billion of cloud, computing and infrastructure obligations Reuters found in the filing equals about 71 years of 2025 compute spending ^[1][1]. Reuters describes the money as due in the coming years. The account relayed by Calcalist does not give a schedule or say whether any of it can be cancelled ^[1].

The operating numbers reconcile. Revenue of nearly $4.6 billion against $12.65 billion of costs leaves a gap of about $8 billion ^[4]. Calcalist, citing Reuters, puts the operating loss at more than $8 billion before writedowns tied mostly to earlier fundraising ^[5]. Compute alone cost more than the company took in from customers ^[5]. Take the roughly $34 billion accounting charge out of the $42 billion net loss and what is left is about $8 billion again ^[6][10].

The obligations look lighter under a few conditions. Revenue could keep compounding: one more twelvefold year would put it near $55 billion, and $518 billion would then be a little over nine years of sales ^[4][6]. The contracts could be back-loaded or cancellable, in which case the near-term cash call is far smaller than the headline figure. Or the listing could clear above $2 trillion ^[7], and Anthropic could raise equity at a price far ahead of its sales.

I think the first condition matters most and is the hardest to count on. The filing says customer usage, and therefore revenue, is driven by new models ^[11]. Chief executive Dario Amodei has called for the industry to slow the pace at which more powerful capabilities are released ^[10]. The same document warns about what more releases bring. "Our development of highly advanced models, platforms, and applications and expansion of use cases could further increase the risk that our models cause harm," Anthropic said in the filing ^[9]. The growth that would shrink the $518 billion depends on the releases the filing flags as a source of harm, so Anthropic is not in a position to slow its own cadence without slowing its sales. The counter-thesis is that twelvefold growth ^[4] already made the 2024 base look small, and one more year like it would do the same to 2025.

The view is wrong if compute spending per dollar of revenue, about $1.59 in 2025 ^[5], falls below $1 in the first public year while revenue keeps growing.
