PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Polymarket and Kalshi differ in market scope and structure. Polymarket offers spread markets (win-by thresholds) and over/under total goals markets with binary outcomes. Kalshi offers only spread markets (win-by thresholds) framed as Yes/No conditions without corresponding under/loss outcomes explicitly stated.Hero Tip:
If you trade spreads on both platforms, outcomes will align (e.g., Roma wins by 2+ goals resolves YES on both). However, Polymarket's over/under and both-teams-to-score markets have no Kalshi equivalents, so cross-platform hedging is impossible for those market types. Stick to spread markets for platform consistency.Critical Divergence Points:
- Polymarket: Aligned with Kalshi on spread logic: Polymarket resolves spread markets (e.g., 'Spread: AS Roma (-1.5)') to the named team if they win by the stated margin or more, otherwise to the opponent. Additionally, Polymarket offers standalone over/under total goals markets (O/U 1.5, 2.5, 3.5, 4.5) and a both-teams-to-score market, none of which appear on Kalshi. All markets resolve on official UEFA.com final score within 90 minutes plus stoppage time, with 2-hour fallback to credible reporting.
- Kalshi: Aligned with Polymarket on spread logic: Kalshi resolves spread markets to Yes if the named team wins by the stated margin (e.g., 'Roma wins by more than 1.5 goals' = Yes), otherwise to No. Kalshi offers only four spread markets (Roma ±1.5, Roma ±2.5) with no over/under or both-teams-to-score equivalents. Resolution basis is the official final score after 90 minutes plus stoppage time, matching Polymarket's scope.
