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 | - Cipher builds and leases the Black Pearl site, about 300 MW gross and 216 MW critical IT, to Amazon Data Services | Cipher Mining | - | Reported | sec.gov |

The read
Cipher Digital's (formerly Cipher Mining) Black Pearl campus near Wink, Texas, converted from bitcoin mining to AI and HPC hosting for Amazon Web Services. Amazon Data Services leases about 300 MW of gross capacity, 216 MW of it critical IT load under contract, on a 15-year triple-net lease (about 5.5 billion dollars) with three optional five-year extensions, signed 3 November 2025. Cipher's investor exhibit lists five construction subphases, with the first data hall (35 MW IT) and a network hall (15 MW IT) rack-ready by 30 September 2026 and Data Hall 4 (81 MW IT) by 28 February 2027; an August 2026 report says rent commenced in early August 2026, first-phase halls are still being finished and the second phase is under construction. Air-cooled and liquid-cooled racks are planned. Cipher does not state a GPU model or count; AWS owns the compute. Cipher is recorded as operator. The tier is reported. It has never submitted an HPL result.
