    Estimate, not a measurementconcentration 3 + substitution 3 + lead time 2 + inelasticity 3 = 11 of 12. The corpus tracks five producers of prime 300 mm wafers.

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.

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.
