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 |
|---|---|---|---|---|---|
| Accelerator | - NVIDIA Blackwell and Vera Rubin platforms, including GB300 NVL72 and Vera Rubin NVL72, across the 310 MW campus; no unit count stated | NVIDIA | - | Reported | nebius.com |

The read
A 310 MW multi-building AI factory that Nebius announced on 31 March 2026 on an industrial site of about 100 acres in Lappeenranta, Finland, with first capacity for customers in 2027. Nebius names NVIDIA Blackwell and Vera Rubin platforms (GB300 NVL72 and Vera Rubin NVL72) as the hardware, a closed-loop liquid cooling system with heat recovery, and describes it as one of Europe's largest dedicated AI compute deployments. The only source is Nebius's own announcement, so the tier is reported and no GPU count is stated. It has never submitted an HPL result.
