Justified Data (Anthropic)
Also known as TeraWulf Justified Data campus
Operated by Anthropic at Hawesville Justified Data Campus .
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.

The read
TeraWulf's Justified Data campus in Hawesville, Kentucky, where TeraWulf signed a 20-year lease with Anthropic on 6 July 2026 for 401 MW of critical IT load, worth about 19 billion dollars of contracted revenue with investment-grade credit support. Initial capacity is due in the second half of 2027 and the full 401 MW by early 2028. Neither the SEC exhibit nor the trade report names accelerators or a power supplier, and the exhibit does not say construction has started, so the status is planned. The trade report is derived from the TeraWulf announcement, so the tier is reported.

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.
