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.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
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 | - Galaxy develops and leases the Helios campus to CoreWeave under 15-year leases (133 MW critical IT delivered in Phase I, 526 MW committed across three phases) | Galaxy Digital | - | Reported | prnewswire.com |
AI datacenter metrics
Figures beyond an accelerator count, each with who stated it. What can and cannot be compared across AI datacenters.
| Metric | Value | As of | Basis | Note | Source |
|---|---|---|---|---|---|
| Accelerators | 63,151 accelerators | 2026-08-30 | Third-party estimate | Epoch AI chip estimate, latest per chip type (B200); some rows are company disclosures, others modelled. | epoch.ai |
| Stated investment | 5 USD bn | 2026-08-30 | Third-party estimate | Epoch AI modelled build cost, compute plus construction, 2025 USD, scaled from IT power; not a disclosed spend. | epoch.ai |
| Facility power | 200 MW | 2026-07-06 | Operator stated | Galaxy: about 200 MW gross power for Phase I. Phase I only; 800 MW gross approved and contracted across the three CoreWeave phases. | prnewswire.com |
| IT power | 133 MW | 2026-07-06 | Operator stated | Galaxy: Phase I complete, 133 MW critical IT delivered to CoreWeave. Phase I only; CoreWeave has committed 526 MW across three phases. | prnewswire.comtheblock.co |

The read
Galaxy Digital's Helios campus in Dickens County, West Texas, a former bitcoin-mining site converted to AI and HPC and leased in full to CoreWeave. On 6 July 2026 Galaxy announced Phase I complete, delivering about 200 MW of gross power and 133 MW of critical IT load to CoreWeave; CoreWeave has committed 526 MW of critical IT load across three phases under 15-year leases, which Galaxy describes as the full 800 MW of gross power currently approved and contracted. Phase II is a 260 MW critical-IT greenfield build with data-hall deliveries expected from the first half of 2027, and the campus approved power capacity is stated as 1.63 GW with potential to reach 3.6 GW. CoreWeave is recorded as operator because it is the named tenant, following the Polaris Forge 1 convention, while Galaxy is the developer and landlord. Neither fetched page names the GPU model or count, so no accelerator is recorded. Both sources are a Galaxy press release and a trade write-up of Galaxy's announcement, 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.
