PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Kalshi market contains a logical contradiction where all three possible outcomes resolve to Yes, making the market fundamentally unresolvable. Polymarket markets are logically consistent and mutually exclusive.Hero Tip:
Do not trade the Kalshi market in its current form. The resolution logic is broken—all outcomes cannot resolve to Yes simultaneously. Contact Kalshi support for clarification. Use Polymarket's three separate markets as your authoritative reference, as they are logically sound and mutually exclusive.Critical Divergence Points:
- Kalshi: Market structure is logically contradictory. All three conditions (Tie, Blackburn win, Portsmouth win) are stated to resolve to Yes. This violates binary market logic and makes the market unresolvable. Key Quote: 'If Tie wins...then the market resolves to Yes. If Blackburn wins...then the market resolves to Yes. If Portsmouth wins...then the market resolves to Yes.'
- Polymarket: Three separate, mutually exclusive binary markets with sound logic: Draw (Yes if draw, No otherwise), Blackburn Win (Yes if Blackburn wins, No otherwise), Portsmouth Win (Yes if Portsmouth wins, No otherwise). Consistent cancellation rules apply: postponement keeps market open; full cancellation resolves Draw to Yes and win markets to No. Key Quote: 'If the game ends in a draw, this market will resolve to Yes. Otherwise, this market will resolve to No.'
