How to buy or sell spare GPUs, transformers and data center capacity: 6 steps

The parts that hold up the AI build-out can't be ordered off the shelf. Our capacity exchange connects people who have spare capacity with people who need it. Here is how it works.

1Choose buy or sell

Tell us whether you are offering capacity or looking for it.

2Pick a category

GPU compute, GPU hardware, data-center space, power and interconnect slots, transformers and switchgear, turbines and gensets, cooling, optics and networking, memory and storage.

3Describe what you have or need

Model, quantity, location, timing and any price guide.

4Add your contact details

Your details are never published.

5We review every listing by hand

Submissions go only to our team.

6We introduce matches privately

When we see a fit, we connect both sides by email. We don't take part in the transaction.

Why an exchange for AI capacity

Long lead times create mismatches: one company has a transformer it no longer needs, another has a project stalled for want of one. A GPU cluster reserved for a project that slipped can be useful to someone else today. Most of these trades happen through personal networks; the exchange widens that network.

Tips for a good listing

Be specific: exact model and configuration, quantity, location, delivery or availability date, and contract terms. For power equipment, include ratings (for example MVA and voltage) and condition. For powered sites, include the interconnection status and energisation date.

Check current GPU prices and equipment lead times before you price a listing.
