PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Polymarket explicitly defines cancellation outcomes (draw resolves YES, wins resolve NO) while Kalshi provides no cancellation clause. Additionally, Kalshi's three mutually-exclusive YES conditions lack clarity on which single outcome resolves YES, creating ambiguity if multiple conditions could theoretically apply.Hero Tip:
Traders should note that Polymarket's draw market is the only contract that benefits from a full cancellation scenario. If you are long the draw on Polymarket, a cancellation is favorable; if you are long any win market on Polymarket, cancellation is unfavorable. Kalshi's silence on cancellation is a red flag—contact support to confirm whether Kalshi will mirror Polymarket's cancellation rules or adopt a different protocol. For postponements, both platforms remain open, so no immediate settlement risk.Critical Divergence Points:
- Polymarket: Three separate markets: San Jose win (YES if San Jose wins, NO otherwise), Draw (YES if draw, YES if canceled with no makeup, NO otherwise), Seattle win (YES if Seattle wins, NO otherwise). All reference 90 minutes plus stoppage time. Postponements keep market open; full cancellations trigger the divergent YES/NO outcomes noted above.
- Kalshi: Single event group with three outcome conditions: Tie wins (YES), Seattle wins (YES), San Jose wins (YES). All reference 90 minutes plus stoppage time. No explicit cancellation or postponement language provided. Logical structure implies only one outcome resolves YES, but cancellation handling is undefined.
