Anthropic in Talks to Lease 1GW Data Center, Seeking Direct Control Over Computing Power by Bypassing Cloud Providers
nashnova research
Anthropic is in early talks with Stream Data Centers to lease up to 1 GW of compute capacity — its largest direct-lease deal yet, and a decisive move away from renting chips through AWS and Google toward owning the infrastructure itself.
How big is this deal?
Anthropic would move in as a direct tenant at a Stream-developed facility, with capacity up to 1 GW.
Industry estimates put the capital cost of 1 GW at no less than $40 billion. This means → just the building and power alone cost a fortune, before a single chip goes in.
Google may provide credit backing for the project, though the exact scope remains unclear.
Why bypass AWS and Google Cloud?
Today, the vast majority of Anthropic's compute comes from renting chip servers through AWS, Google, and others — essentially running on someone else's turf with someone else's gear.
The logic of direct leasing: buy and operate your own servers, cutting out the cloud provider's margin. In plain terms = skip the middleman's markup.
Beyond cost savings, Anthropic gains greater control over chip pricing, supply timing, and technical architecture. This reflects a rising anxiety among AI companies about supply-chain security for compute.
What chips will go inside?
Anthropic plans to deploy TPUs jointly designed by Broadcom and Google (tensor processing units — chips purpose-built for AI training).
Nvidia GPUs are also on the shortlist. This means → Anthropic is keeping its options open, preserving bargaining leverage across chip suppliers.
On the chip side, Anthropic has already struck a 2 GW chip-lease deal with AMD this year and signed a $35 billion TPU lease through a special-purpose vehicle set up by Apollo and Blackstone.
Has Anthropic done this before?
Yes, on a smaller scale: it previously signed data-center leases with former Bitcoin miners Hut 8 and TeraWulf.
If the Stream deal closes, it would far exceed those earlier agreements and become the company's largest single direct lease.
Over roughly the past 11 months, Anthropic has signed compute agreements totaling $531 billion — but the bulk still runs through cloud-provider channels.
What are its rivals doing?
OpenAI last month signed an initial lease for a data center in Ohio with planned capacity of 10 GW — ten times the scale Anthropic is negotiating here.
OpenAI also secured up to $105 billion in credit support from Nvidia. This means → on the "build your own compute" track, OpenAI is moving faster and with deeper backing.
Anthropic's $531 billion in total compute agreements is a large headline number, but its direct-lease share remains small. Whether it can deliver on the cost savings depends on execution in procurement and operations.
What could still go wrong?
People familiar with the matter say the Stream deal is still months from signing, and talks could fall apart.
The exact capacity and deal structure are both still under negotiation.
Anthropic still needs financial guarantees for the lease and separate financing for the chips inside. In plain terms = the building isn't signed yet, and the money for the fit-out isn't lined up either.
