01Chokepoints it holds

1 of 1 sourced

Score = concentration + substitution + lead time + inelasticity, each 0–3, an analyst judgement dated 2026-09-15; open a score for its rationale and assessment. Makers are those the corpus records, not the whole market. No market-share figure is sourced, so none is shown.

04What could loosen its grip

about its chokepoints, not the company
  • Amorphous metal transformer cores

    Transformer cores wound from rapidly cooled metal ribbon that has no crystal structure, instead of the grain-oriented silicon steel the industry is short of.

    readiness
    Estimate, not a measurementIn production at scale. In production at scale, but only for part of the problem. ABB has sold amorphous metal distribution transformers for two decades; the constraint is applicability rather than maturity, because the lower saturation induction means a larger core cross-section, larger coils and a larger footprint — acceptable on a pole, not on a grid-scale unit.By Substrata · 2026-09-18Supporting source →/9

Readiness is the 1–9 technology-readiness scale, a dated judgement; open a figure for the reasoning and its source.

06Ways to take part

how to reach it, not whether to

Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not

08What this holds up

2 loops

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
