W.E.T. Score
How much signal is behind this number?
The W.E.T. Score grades the evidence, not the outcome. Five inputs — comparable volume evidence, news corroboration, cross-venue verification, market coverage, and track-record depth — scored against how much verifiable signal sits behind the headline probability.
Scored from the final settled snapshot · 30/100 · Thin Signal
| Component | Points | What the data says |
|---|---|---|
| Liquidity | 10/30 | The event combines unlike venue-native volume units. W.E.T. does not add contracts to dollars, so this component remains at the documented neutral 10/30. |
| News corroboration | 0/20 | No wire headlines matched this event at snapshot time — the price stands alone. |
| Cross-venue verification | 8/20 | No canonical exact-match pair is available for this snapshot. Related listings are not compared, so this component remains at the documented 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 | 0/15 | 0 attributable days tied to one venue, favorite, and listing key. Legacy unkeyed points earn no depth credit. |
The W.E.T. Score measures evidence quality — comparable volume, verified agreement, coverage, and corroboration behind a price. Venue-reported contract counts are never treated as dollars. 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.

Why settled odds still matter
A settled market is a permanent record of what traders collectively expected before the outcome was known — the raw material for judging how well prediction markets forecast the real world. This page archives the market's final pre-close read; the official resolved outcome is published by the venue itself. Comparing final reads to outcomes across many markets is how prediction-market accuracy is measured.
