Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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.

The read
Nebius signed a letter of intent in October 2026 to be first offtaker of Volt's planned Rotterdam campus: 600 MW across six buildings, with a first phase of two 100 MW data centres costing about 7 billion euros (7.8 billion dollars) including construction and computing hardware. Electricity would come from nearby offshore wind farms through Eneco. Baxtel describes the project as a planned EU AI gigafactory, but the EuroHPC AI Factories page fetched for this sweep lists no selected AI Gigafactory sites, so that label is unconfirmed. No GPU type or count, construction start or energisation date is given, and a letter of intent is not a lease. Nebius's other European sites include nebius-bethune and nebius-lappeenranta.
