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.

The read

A 2,842-acre campus at Cedar Creek in Bastrop County, Texas, about 26 miles south east of Austin, developed by Pacifico Energy (a 710 MW gas-fired plant, supporting about 490 MW of data center load, run independently of the ERCOT grid) and BlackChamber Group (the data center, through Black Chamber Partners); estimated total investment 2.2 billion dollars. A 7 October 2026 filing with the Texas Department of Licensing and Regulation lists a 498,165 square foot first building (366 million dollars, construction 30 November 2026 to 31 January 2028) as the first of two. Baxtel, citing Austin Business Journal, reports Anthropic is in talks to lease the site, but the filing names no tenant and no lease is final; the same article notes stormwater permit challenges, withdrawn tax abatement requests and a state-ordered pause on approvals. No accelerator type or count is public.
