Description

Norwich City FC and Derby County FC will compete in an EFL Championship match on April 21, 2026. The outcome will be determined by the result after 90 minutes of regular play plus stoppage time, excluding extra time or penalties. Three mutually exclusive outcomes are possible: Norwich win, Derby win, or draw.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market structure is logically incoherent: all three outcome markets (Tie, Norwich win, Derby win) resolve YES simultaneously, making it impossible to determine a single winner. Polymarket markets are mutually exclusive and resolvable.Hero tip: Avoid Kalshi markets in this group entirely. They violate basic mutual exclusivity — you cannot simultaneously win bets on all three outcomes. Polymarket offers three properly exclusive markets where exactly one resolves YES.

Critical divergence points:

  • Polymarket: Three mutually exclusive binary markets: Norwich Win (YES/NO), Draw (YES/NO), Derby Win (YES/NO). Exactly one outcome occurs; exactly one market resolves YES. Resolution source is official EFL statistics or credible consensus within 2 hours of match conclusion. Postponement keeps markets open; cancellation with no makeup resolves Draw to YES, others to NO.
  • Kalshi: Three separate YES/NO markets, each stating 'If [outcome] occurs, then resolve to Yes.' All three markets resolve YES if any outcome occurs, creating logical impossibility. No cancellation or postponement rules provided. Quote: 'If Tie wins... then resolves to Yes. If Norwich wins... then resolves to Yes. If Derby wins... then resolves to Yes.'
