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.

| Component | Points | What the data says |
|---|---|---|
| Liquidity | 0/30 | No positive venue-reported volume was available at snapshot time. |
| News corroboration | 16/20 | 2 live wire headlines lexically matched to this event — real, citable corroboration that the story is moving. |
| 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. Full weighting and worked examples in the methodology.

This page archives the market's final pre-close read; the official resolved outcome is published by the venue itself.
