Lake Mariner Anthropic AI Factory

Kind: datacenter
Location: Lake Mariner, NY
County: Niagara
State/region: NY
Country: United States
Declared cost: $3.5 billion (financing target for Anthropic-leased facility, per July 13, 2026 headline)
Announced: 2026-07-09
Status: partially operational as of October 3, 2026

Where it stands

TeraWulf's Lake Mariner campus in New York has 102 MW of critical IT capacity in service and generating revenue, with another 336 MW under construction in CB-4 and CB-5. The total is 438 MW contracted to Core42 and Fluidstack. The passages do not tie Anthropic to Lake Mariner: Anthropic's 401 MW, 20-year lease is at the Justified campus in Hawesville, Kentucky. These figures are therefore for the Lake Mariner campus, and the 'Anthropic AI Factory' label may be a mis-attribution. Needham and the CEO said New York's moratorium does not affect Lake Mariner.

Analytical estimate. Each site below is located from public records (filings, releases, news, OpenStreetMap) and checked against free satellite imagery; "How we located this site" lists every step and the score it earned. The conclusion is computed from night-time lights, surface heat and year-over-year change, with the dates it rests on. These are hypotheses under active tracking, not legal parcels or an official endorsement.
