PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both platforms measure the identical event (Portsmouth vs Derby on March 16, 2026, 90 minutes plus stoppage time) with consistent outcome definitions, though cancellation handling differs slightly between platforms.
Primary resolution logic:
Official EFL Championship match records and on-field officials' final determinationCore resolution logic:
- Match outcome is determined by the official final score after 90 minutes of regular play plus stoppage time
- Three mutually exclusive outcomes: Portsmouth FC win, Derby County FC win, or draw
- Extra time and penalties are excluded from resolution scope
- Resolution occurs immediately upon match completion or official cancellation
Edge cases & Clarifications:
- Match Postponement: If the match is postponed, all markets remain open and unresolved until the rescheduled match is completed. Markets do not resolve based on postponement alone.
- Match Cancellation (No Rescheduling): Polymarket: Draw market resolves Yes; Portsmouth and Derby win markets resolve No. Kalshi: All three outcome markets resolve Yes (per the provided rules). This represents a minor platform divergence in cancellation protocol.
- Stoppage Time Clarification: Resolution includes all stoppage time added by the referee at the end of the 90-minute period. Goals scored during stoppage time count toward the final result.
Timing:
Resolution occurs immediately upon official match completion on March 16, 2026, or upon official cancellation with no rescheduled date. If postponed, resolution is deferred until the rescheduled match concludes.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
