Amazon just turned up the funding spigot for Anthropic — again. On Sunday, reports confirmed that the cloud giant plans to invest up to $25 billion in the company behind Claude, on top of the $8 billion it has already poured in. An initial $5 billion tranche flows immediately, with the rest tied to milestones.
What Anthropic gives back
This isn’t charity. In return, Anthropic has committed to spending over $100 billion on AWS services over the next decade. That means Claude’s training and inference will run primarily on Amazon infrastructure — specifically on the company’s custom Trainium chips, generations 2 through 4. Trainium4 doesn’t even exist yet, which tells you how far ahead both sides are planning.
The deal also includes up to 5 GW of new computing capacity. For context, that’s more electricity than some European cities consume.
Amazon is hedging every bet
Here’s what makes this interesting. Earlier this year, Amazon also invested up to $50 billion in OpenAI — partly structured as cloud credits. AWS boss Matt Garman publicly defended the dual approach: customers want choice. In practice, it means that no matter which AI company wins, Amazon collects the cloud bill.
What this means for Claude
For Anthropic, the deal is a show of strength. The company reportedly turned down VC funding offers at valuations north of $800 billion, choosing instead to finance its growth through strategic cloud partnerships — with Amazon, Google/Broadcom, and Microsoft. The message: we don’t need venture capital, we need compute.
And compute is the scarcest resource in AI right now. Between the Broadcom/Google deal earlier this month (3.5 GW), the Microsoft partnership ($30 billion in Azure credits), and now Amazon, Anthropic has built a multi-cloud strategy that few competitors can match.
My take
What impresses me most about this deal is how Anthropic has locked in hundreds of billions of dollars worth of infrastructure — without going public, without giving up control, and without tying itself to a single cloud provider. That’s remarkable in a market where OpenAI just raised $122 billion and is still heading for an IPO.
The open question: when will these investments turn into real returns? $100 billion in AWS costs over ten years is a staggering commitment — even for a company with a $30 billion annual run rate.
