A breadth-first environmental scan of the external forces acting on the AI build-out, organised across the six PESTLE categories: Political, Economic, Social, Technological, Legal, and Environmental. The scan is descriptive and applies no severity weighting - each force is reported with its source and, where applicable, a scenario range, and any interpretation is attributed to the source that made it. It is the complement to the author's Capital-Infrastructure Barbell risk paper, which weights the same subject matter by likelihood times severity; where a force maps to a numbered factor in that risk register, the factor is noted inline. Version 0.5 refreshes the scan to mid-2026 readings across all six categories: the resolution of the Fable 5 / Mythos 5 export suspension and the H200-to-China reversal (Political); off-balance-sheet data-centre lease commitments (about 662 billion USD, Moody's), the dot-com-versus-AI capex-to-sales comparison, and an emerging idle-compute counter-signal (Economic); entry-level labour displacement with its counter-evidence, and a forming social licence including data-centre noise litigation (Social); US-specific power intensity and the 2 August 2026 EU AI Act high-risk deadline (Technological and Legal); and the Lake Powell / Glen Canyon water-and-power coupling (Environmental). Anchors are 2026 market readings plus vintage-labelled structural and projection sources (IEA Energy and AI and the IEA 4E EDNA critical review; Lawrence Berkeley National Laboratory; MIT NANDA GenAI Divide; McKinsey Global Institute trade update; the US Bureau of Reclamation 24-Month Study; the February 2026 Supreme Court IEEPA tariff ruling). Produced with assistance from a large language model that is itself a product of one of the actors described; that conflict of interest is stated in the document, and primary coverage is preferred for any Anthropic-favourable reading. Independent analysis, not investment advice.
