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 Rosemount, Minnesota data center, optimized for AI workloads | Meta Platforms | - | Reported | datacenters.atmeta.com |
| Accelerator | NVIDIA B200 SXM Accelerators CUDA (Blackwell) · TSMC 4NP · 1,000 W Epoch AI estimate: about 85,400 NVIDIA B200 GPUs (modelled, not disclosed by Meta) | NVIDIA | 85,400 estimated | Reported | epoch.ai |

The read
Meta's Rosemount, Minnesota data center, announced on 14 March 2024 as an investment of more than 800 million dollars across 715,000 square feet on former UMore Park land, powered by new renewable projects and described by Meta as optimized for its AI workloads. Meta publishes no capacity or hardware. Epoch AI's AI data centers dataset (CC BY 4.0) estimates about 85,400 B200 chips and 178 MW of IT power, with buildings 1 and 2 estimated operational by June 2026 from satellite imagery and an air quality permit. Meta has not announced an in-service date, so operational status and the figures are Epoch's modelled estimates, recorded in the metrics table only. Hardware rests on Epoch alone, so the tier is reported.
