Operated by Cipher Mining .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Cipher Mining provides most financing of the 1 GW Colchis site, about 95 percent equity expected | Cipher Mining | - | Reported | theblock.cobaxtel.com |
| Power | - AEP executed 1 GW direct connect agreement with dual interconnection, energisation targeted 2028 | American Electric Power | - | Reported | theblock.cobaxtel.com |

The read
A 620-acre, 1 GW site in West Texas next to an existing substation, announced in Cipher Mining's third quarter 2025 update through a joint entity in which Cipher expects about 95 percent equity under a future HPC lease. Cipher holds an executed 1 GW direct connect agreement with American Electric Power, which will build a dual interconnection with energisation targeted for 2028 pending ERCOT's final review. No tenant has been named for Colchis: the 15-year, 5.5 billion dollar, 300 MW AWS lease announced in the same update is at a different Cipher campus (see cipher-black-pearl-aws), and Baxtel lists the AWS and Fluidstack leases against other Cipher sites. The town or county is not given in either source, only West Texas near San Angelo, so no site row is created. No accelerators are specified.
