PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi align on the core resolution: official match outcome after 90 minutes plus stoppage time on February 15, 2026, with no extra time or penalties counted.
Primary resolution logic:
Official Eredivisie (eredivisie.nl) match records and final scorelineCore resolution logic:
- Match resolves based on the official result after 90 minutes of regular play plus stoppage time
- Three mutually exclusive outcomes: Sparta Rotterdam win, NEC win, or draw
- Extra time and penalty shootouts are excluded from resolution
- If match is postponed, all markets remain open until the match is completed
- If match is canceled entirely with no makeup game: draw market resolves Yes, win markets resolve No
Edge cases & Clarifications:
- Match Postponement: If the match is postponed, all markets remain open and unresolved until the match is completed on a future date
- Match Cancellation: If the match is canceled with no makeup game scheduled, Polymarket's draw market resolves Yes while Sparta and NEC win markets resolve No. Kalshi does not explicitly address this scenario
- Extra Time or Penalties: Resolution is based solely on the result after 90 minutes plus stoppage time; extra time and penalty shootouts do not affect resolution
Timing:
Resolution occurs immediately after the match concludes on February 15, 2026, or on the rescheduled date if postponedOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
