What the source record says
Brownfield redevelopment of former Century Aluminum smelter. Site acquired February 2026 from Century Aluminum subsidiary; acquisition price reported by multiple outlets as $200M cash plus a 6.8% minority equity interest in TeraWulf (not confirmed in official PR text fetched). Lease entity: TeraWulf's Raylan Data LLC to Anthropic PBC. The ~$19B is contracted lease revenue over the 20-year term — not capex; excluded from investmentUsd. TeraWulf indicated a $3B–$4B construction investment for two data center buildings (range, not a firm single figure; excluded from investmentUsd). Site has ~480 MW of existing power availability; 401 MW is the Anthropic lease capacity. Total site ~750 acres per news sources; TeraWulf's official PR cited 'over 250 buildable acres.' Coordinates are approximate (Hawesville town center). Fluidstack/Abernathy JV is a separate unrelated transaction — excluded from this record.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
