Amazon Is Building Its Next-Gen AI Data Centers In Under 35 Weeks

Amazon is in a sprint. The AI boom has the cloud giants racing to put up bigger, denser, more power-hungry data centers, and Amazon Web Services just pulled back the curtain on its plan to win.

It's called Titus, and it's all about speed.

The goal: get from breaking ground to running servers in under 35 weeks. That's a major drop from how AWS used to build.

The Plan: Build Faster, Cool Better

Internal AWS documents lay out the Titus playbook. Each new site jumps from about 58 megawatts of compute capacity to roughly 68, packing more power into the same footprint.

The cooling system is the unlock. AWS built its own liquid-cooling tech called the In-Row Heat Exchanger, or IRHX, which lets the company pack in chips that throw off more heat than air cooling can handle.

CEO Andy Jassy talked publicly about IRHX last year, framing it as the system that lets AWS support the newest AI hardware without rebuilding the room around it.

SemiAnalysis analyst Reyk Knuhtsen put it plainly: Amazon is "coming out to the races" with designs built for speed.

Built For Nvidia's Next Chip

Titus isn't just about going faster. It's about going denser.

Internal Amazon documents call for wider aisles built specifically for Nvidia's GB200 systems and the GPUs that come after them.

Capital spending - or CapEx, the money companies put into long-term assets like buildings and equipment - is set to hit a record $200 billion at Amazon this year, with a big chunk of that going into infrastructure that didn't exist on the drawing board two years ago.

A newer version of Titus sites is due to roll out in the first half of 2027.

AWS engineers are also targeting a 10% cut on internal cost and carbon benchmarks while trying to fix what they call "stranded power" - the electricity a site is paying for but not actually using because the racks don't fully load it.

Think of stranded power like renting a 6-bedroom house and only using two rooms. You're paying for the whole thing.

Worth Noting

Titus is one of a few internal Amazon initiatives reshaping how AWS builds. A separate project called Houdini focuses on modular, faster-to-deploy AI sites.

Both point at the same reality: the AI build-out is more about real estate, power, and concrete than it is about software.

The bottom line: cloud margins live or die on this. Faster sites mean revenue sooner, and denser sites mean more chips per dollar of land - and right now, every cloud giant is racing for both.

The shovel side of the AI trade is starting to matter as much as the chip side.
