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.

02Unread leads

6 found by the sweep, unread

Pages the sweep found on these chokepoints. Nobody here has read them yet; they are not events and not evidence.

03What could loosen its grip

about its chokepoints, not the company
  • Gallium nitride power conversion

    Power electronics built on gallium nitride rather than silicon, which waste less energy as heat when converting voltage.

05Ways 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

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.
