The 90-second path through the evidence
Everything below is computed live from recorded data, not staged for this page. Click through each number to the page that backs it.
- 15 bps — median gap between our independent venue composite and CMC's published price
across 37 assets, computed with no knowledge of CMC's own number; widest is M at 35 bps.
- 27 — markets returned twice by the API with conflicting prices
in the latest capture, none flagged by CMC — a data-return bug, not a thin-venue quirk.
- 379% — M perp volume held by one venue (KTX)
the most concentrated asset right now.
- 433 assets — OKX quotes off-market, and CMC does not exclude it
822 of 899 captures, typically 81% below the median.
Reproduce it yourself: node --no-warnings --env-file=.env.local scripts/report.mjs prints every number above from the live recorded data. No CMC credits spent — it reads only what was already captured.
Raw, unedited API responses: scripts/out/ on GitHub. Tests: 105, node --no-warnings --test, offline.
What this doesn't show: whether CoinMarketCap's headline price actually uses the flagged rows, or whether any exchange's volume is real. See how this works for the rest of what has and hasn't been checked.
