Methodology

Every day we freeze the canonical semiconductor cost/pricing data into an append-only ledger. This page compares the most recent snapshot against the closest one ~30 days earlier and surfaces the metrics that moved past a per-dataset significance threshold (filtering out rounding noise).

Each movement shows direction, magnitude (percent for value metrics, percentage-points for rate metrics), the two dates compared, and a confidence tier. The trend column sketches each metric's full ledger history (up to ~90 days). The history is young — the ledger began 2026-06-06, and some domains are tracked from later dates — so a 30-day window automatically clamps to the data available and labels the real lookback, and per-row trends can start on different dates. Underlying values are synthesized from public sources only.

Programmatic access: /api/v1/changes and the get_recent_changes MCP tool. For data provenance and terms, see Terms & Data Provenance.
