The decision to commit five gigawatts of compute capacity wasn't made lightly inside Anthropic. But when the company’s official account posted on April 20 that it was “expanding our collaboration with Amazon to secure up to 5 gigawatts,” it signaled a bet that goes far beyond the usual cloud partnership. Internal documents circulating among Anthropic’s infrastructure team show that this is not a single data center build-out, but a multi-year, multi-site agreement designed to power the next generation of frontier models—including the rumored Claude 5 architecture.

Engineers close to the project say the rollout has been anything but smooth. The initial target was 3.2 gigawatts by early 2027, but Amazon’s AWS side has struggled with regional grid interconnection delays, particularly in northern Virginia and parts of Ohio where data center construction has outpaced local utility capacity. Anthropic’s infrastructure lead has privately acknowledged that the revised 5-gigawatt figure assumes Amazon can bring two new “hyperscale campuses” online simultaneously, a timeline that sources inside AWS describe as “ambitious.”

What makes this deal strategically important is the shift in how Anthropic is spending its capital. Instead of leasing compute by the hour, the company is effectively co-investing in dedicated power and hardware—a model pioneered by Microsoft and OpenAI, but taken to a new scale for a startup. The agreement covers both training and inference workloads, meaning Anthropic expects long-term demand from enterprise customers who want to run models in a dedicated, low-latency environment. This also reduces exposure to Nvidia’s allocation cycles, since Amazon’s custom Trainium chips will be a primary compute layer.

What remains uncertain is the regulatory path. The 5-gigawatt commitment requires environmental impact reviews in multiple states, and some local utility boards have already pushed back on the combined load. Anthropic has not commented on specific site locations, but people familiar with the planning say at least one facility is targeting a 2028 in-service date.

For now, the bet is clear: Anthropic is positioning itself as the infrastructure-heavy player in the AI race, trading flexibility for guaranteed capacity. Whether Amazon can deliver the power on time is the open question that will define Claude’s next evolution.
