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 1581 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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Core Scientific Marble 1 high-density data center, 117 MW total power capacity | Core Scientific | - | Reported | corescientific.com |
| Accelerator | - Epoch AI: about 15,000 Grace Blackwell GPUs supported at the two-hall 36 MW stage in March 2026 (estimate; Epoch also types the chips as B200) | NVIDIA | 15,000 estimated | Reported | epoch.ai |

The read
Core Scientific's Marble 1 campus near Marble, North Carolina, a former bitcoin-mining site converted to high-density GPU hosting for CoreWeave. Core Scientific's own page lists 117 MW of total power capacity on a 70-acre, 250,000 sq ft campus and names no GPU model or count. Epoch AI's tracker (CC BY 4.0) relays Core Scientific disclosures that two of three data halls were delivered at about 36-37 MW in March 2026, supporting about 15,000 Grace Blackwell GPUs, and that on 6 May 2026 Marble was fully handed over to CoreWeave with about 65 MW of billable power; Epoch itself estimates about 79k H100-equivalents and a 2.5 bn USD build cost, and types the chips as B200 even while quoting 'Grace Blackwell', so the GPU model is unconfirmed and the 15,000 figure describes the earlier two-hall stage. CoreWeave is recorded as operator because it is the tenant, as with Denton (core-scientific-denton-coreweave) and Muskogee (core-scientific-muskogee-coreweave). Hardware and operating power rest on Epoch alone, so those figures sit in the metrics table as estimates.
