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.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
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 |
|---|---|---|---|---|---|
| Accelerator | NVIDIA H200 SXM Accelerators CUDA (Hopper GH100) · 16,896C · 1.98 GHz · TSMC 4N · 700 W NVIDIA H200 GPUs arriving at Kansas City alongside already-installed H100s; Blackwell expected in 2025; about 35,000 GPUs at full 40 MW capacity | NVIDIA | - | Reported | nebius.com |

The read
Nebius's first US GPU cluster, a colocation deployment in Kansas City, Missouri announced in November 2024: Nebius stated an initial 5 MW expandable to 40 MW, about 35,000 GPUs at full potential capacity, with NVIDIA H100 GPUs already installed, H200 GPUs arriving and Blackwell expected in 2025. Nebius's Q2 2025 shareholder letter (filed with the SEC) says the Kansas City data center officially launched in April 2025 with more compute added in early July. The Q1 2026 letter lists Kansas City among sites with more than 100 MW, but gives no detail, so the 40 MW figure is the stated expansion ceiling at announcement. Both sources are Nebius's own, so the tier is reported. It has never submitted an HPL result.
