How to read the numbers

Implied / market-implied YES

The probability of YES implied by current traded prices (mid or last). It is what participants are paying for, not a claim about real-world odds.

Model estimate

A rule-based heuristic from the signal engine when a rule sets one, not a black-box forecast. Some signals only describe liquidity or spreads and may show no model estimate.

Edge / gap

The difference between the model estimate and market-implied, in percentage points (model minus market for YES). Filters may use “largest gap.” This is informational only-not trading advice or guaranteed advantage.

Stance (above / below / near estimate)

Compares market-implied to the model estimate when both exist. Labels are not buy or sell recommendations.

Confidence

A simple UI clarity label for signals (not a prediction). It summarizes the signal’s own magnitude/quality metrics into one of: Low, Mid-low, Mid, Mid-high, or High.

Volume

Reported trading activity for the market, for context on size and liquidity.

Change & sparklines

Movement in market-implied YES over the window labeled on the card-often 24h where data allows.

Signals

Rule-based flags from ingested public data. They are not trade recommendations.

United Kingdom local elections are currently scheduled to be held on May 7, 2026. This market will resolve to "Yes" if a Green Party candidate wins a mayorship as a result of this election. Otherwise, this market will resolve to "No". A candidate will be considered an official candidate of the Green Party if they are officially nominated by the Green Party and are registered for the relevant election in affiliation with the Green Party. Independent candidates will not count for any party. Only the following mayoral elections scheduled to be held on May 7, 2026, will qualify for this market: Croydon, Hackney, Lewisham, Newham, Tower Hamlets, and/or Watford. Temporary, interim, or placeholder mayors appointed before the election will not be considered. Resolution of this market will be based on the results of the relevant elections, once those results are official. If the results of any of the relevant elections aren’t known by April 30, 2027 11:59 PM ET, this market will resolve based on the available results up to that point. If none of the results of the relevant elections are known by that time, this market will resolve to “No”. This market will resolve based on the results of the elections as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the respective council government.
