iPhone supply chain chokepoints

category tradeable chokepoint

How scores are shown

Criticality

Comes from the trace model and describes the node's dependency importance.

Evidence

Comes from the canonical Vein Graph: AI assertions, user corrections, and external sources. Provisional — needs corroboration or an external source before strong wording.

Completeness

A data-coverage label based on available summary, evidence, sources, tickers, and chokepoint rationale.

Dynamic claims are capped below 100% and AI-only edges remain labeled as inferred.

Model: trace-score-v1

⚠ Hidden chokepoints found

Apple A-series SoC44% confidence — Single-source leading-edge fab (TSMC) and EDA toolchain create supply risk.

EUV lithography equipment44% confidence — ASML is the sole commercial EUV supplier; export controls affect China access.

ITO / transparent electrode materials44% confidence — Indium refining is concentrated; Samsung & LG dominate OLED fab capacity.
