Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of

One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

Role	Part	Supplier at build	Quantity	Confidence	Source
Integrator	- Meta designs, builds and operates the 715,000 sq ft Cheyenne, Wyoming data center, optimized for AI workloads	Meta Platforms METANASDAQ	-	Reported	datacenters.atmeta.com
Accelerator	- Epoch AI estimate: about 68,400 NVIDIA B300 GPUs (modelled, not disclosed by Meta)	NVIDIA NVDANASDAQ	68,400 estimated	Reported	epoch.ai

AI datacenter metrics

Figures beyond an accelerator count, each with who stated it. What can and cannot be compared across AI datacenters.

Metric	Value	As of	Basis	Note	Source
Accelerators	68,400 accelerators	2026-10-02	Third-party estimate	About 68,400 B300. Epoch AI chip estimate (modelled from satellite imagery, cooling equipment and chip availability); not an operator disclosure.	epoch.ai
Stated investment	0.8 USD bn	2024-07	Operator stated	Meta: investment of more than 800 million dollars at announcement; floor value, buildings and fit-out not split from compute	datacenters.atmeta.com
IT power	152 MW	2026-10-02	Third-party estimate	Epoch AI modelled IT power from satellite imagery and permits; not operator-stated. Epoch projects 207 MW by Q1 2027.	epoch.ai

How it is powered

Source	Provider	MW	Status	As of	Basis	Note	Source link
Grid	Black Hills Energy	-	operating	2026-10	Operator stated	Meta says it worked with Black Hills Energy to plan energy for the Cheyenne data center and pays full costs; no MW stated.	datacenters.atmeta.com
Wind and solar	-	365	contracted	2026-10	Operator stated	Meta says one Wyoming project it supports adds 365 MW of new clean energy to the grid. Used to match its electricity use; not a direct supply to the site.	datacenters.atmeta.com
Battery storage	-	200	contracted	2026-10	Operator stated	The same Wyoming project Meta supports adds 200 MW of battery storage to the grid; a grid-side addition, not on-site storage.	datacenters.atmeta.com

How AI campuses are powered: capacities are what the operator, utility or filing states, not what has been delivered.

The read

Meta's Cheyenne, Wyoming data center, announced on 2 July 2024 as an investment of more than 800 million dollars across 715,000 square feet, with Black Hills Energy adding new grid resources and a description of the site as optimized for Meta's AI workloads. Meta publishes no capacity or hardware. Epoch AI's AI data centers dataset (CC BY 4.0) estimates about 68,400 B300 chips and 152 MW of IT power, with both initial buildings estimated operational by July 2026, and projects about 207 MW by Q1 2027, from satellite imagery and permit records. Meta has not announced an in-service date, so operational status and these figures are Epoch's modelled estimates in the metrics table only. Hardware rests on Epoch alone, so the tier is reported. Separate from NCAR's Cheyenne supercomputer.
