PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi align on the same match, time window (90 minutes plus stoppage time), official resolution source (a-league.com.au), and contingency logic for postponement, cancellation, and incomplete matches.
Primary resolution logic:
Official A-League statistics published on a-league.com.au; if unavailable within 2 hours post-match, credible reporting consensusCore resolution logic:
- Both Teams to Score resolves YES if each team scores at least one goal; NO if either team scores zero goals
- Spread markets (Western Sydney -2.5, -1.5 and Adelaide -2.5, -1.5) resolve based on goal margin: -2.5 requires 3+ goal win, -1.5 requires 2+ goal win
- Over/Under markets resolve based on combined total goals: O/U 1.5 (2+ goals = Over), O/U 2.5 (3+ goals = Over), O/U 3.5 (4+ goals = Over), O/U 4.5 (5+ goals = Over)
- All markets reference only the first 90 minutes of regular play plus stoppage time, excluding extra time and penalties
Edge cases & Clarifications:
- Match Postponement: Markets remain open until the match is completed; no early resolution
- Match Cancellation: If the match is canceled entirely with no makeup game scheduled, all markets resolve 50-50
- Incomplete Match: If the match starts but is not completed, resolution uses the official final score published on a-league.com.au
- Source Delay: If official statistics are not published within 2 hours after match conclusion, a consensus of credible reporting may be used instead
Timing:
Resolution occurs after the match concludes (90 minutes plus stoppage time) and official statistics are published on a-league.com.au, or within 2 hours thereafter if consensus reporting is requiredOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
