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 | - TeraWulf holds the majority stake in the joint venture developing the 168 MW critical IT Abernathy campus (agreed in July 2026 to sell its 50.1 percent interest) | TeraWulf | - | Reported | investors.terawulf.cominvestors.terawulf.com |

The read
A 120-acre HPC campus at Abernathy, Texas, developed as a majority-owned TeraWulf joint venture with Fluidstack under a 25-year lease worth about 9.5 billion dollars, with Google backing about 1.3 billion dollars of Fluidstack's lease obligations. TeraWulf's 28 October 2025 release states 168 MW of critical IT load (240 MW gross) with delivery in the second half of 2026. In its Q2 2026 results TeraWulf said it agreed to sell its entire 50.1 percent interest in the joint venture for about 530 million dollars; the buyer is not named in the fetched page. No fetched page confirms delivery, so status is under_construction. No page names the compute hardware. Both sources are TeraWulf's own, so the tier is reported. It has never submitted an HPL result.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
