W.E.T. Score
How much signal is behind this number?
The W.E.T. Score grades the evidence, not the outcome. Five measurable inputs — traded volume, news corroboration, cross-venue agreement, market coverage, and track-record depth — scored against how much verifiable signal sits behind the headline probability.
Scored from the July 21, 2026 snapshot · 53/100 · Developing Signal
| Component | Points | What the data says |
|---|---|---|
| Liquidity | 24/30 | $275.1K in matched volume across this event's markets. Log-scaled: thin books score near zero, $1M+ maxes the component. |
| News corroboration | 0/20 | No wire headlines matched this event at snapshot time — the price stands alone. |
| Cross-venue agreement | 8/20 | Priced on one venue only — no independent book to check the number against, so this component sits at a neutral 8/20. |
| Market coverage | 12/15 | 8 tracked markets on this event — more side markets and strikes mean more angles pricing the same story. |
| Track-record depth | 9/15 | 6 days of daily probability history on file. A longer tape shows how the price behaves, not just where it sits. |
The W.E.T. Score measures market microstructure — how much money, agreement, coverage, and corroboration sit behind a price. It is not a prediction of the outcome, not a rating of whether the favorite wins, and not trading advice: a Thin Signal market can still resolve YES, and a Prime Signal market can still resolve NO. Full weighting and worked examples in the methodology.
