fully-built cost of a gigawatt-scale AI campus incl. IT (all-in ~$30/W; Epoch models ~$38B of up-front capex for a stylized 1 GW-IT US hyperscaler campus, plus ~$0.9B/yr opex)

Value kindobserved — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range.
CaveatThe ~$38B is Epoch's UP-FRONT CAPEX for a stylized 1 GW-IT campus (May-2026 CSV: servers 21.2 + facility 11.4 + network 4.9 + land 0.17 + utility 0.16 = $37.9B). Financing is not included; land is, at a trivial $172M — correcting an earlier note here that placed land in opex. Epoch's annualized TCO for the same campus is ~$8.5B/yr.
