Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi use identical resolution logic: the market resolves based on the official match outcome (win, loss, or draw) within 90 minutes plus stoppage time on April 25, 2026, with the same primary resolution source (official governing body statistics or credible consensus reporting).
Primary resolution logic:
Official statistics from HNL (Croatian Football League) or credible reporting consensus if official statistics are not published within 2 hours after match conclusion.
Core resolution logic:
Exactly one of three mutually exclusive outcomes will occur: NK Slaven Belupo wins, HNK Vukovar 1991 wins, or the match ends in a draw.
Polymarket resolves three separate binary markets (Belupo win YES/NO, Draw YES/NO, Vukovar win YES/NO), with exactly one resolving YES.
Kalshi resolves three separate binary markets (Belupo win YES, Draw YES, Vukovar win YES), with exactly one resolving YES.
Resolution is based only on the result within 90 minutes of regular play plus stoppage time, excluding extra time and penalties.
If the match is postponed, all markets remain open until the match is completed.
If the match is canceled entirely with no make-up game, Polymarket's Belupo and Vukovar markets resolve NO, and the Draw market resolves YES. Kalshi's markets would resolve based on the cancellation outcome (tie/draw interpretation).
Edge cases & Clarifications:
Match Postponement: If the match scheduled for April 25, 2026 is postponed, all markets on both platforms remain open and unresolved until the match is actually completed.
Match Cancellation Without Makeup: If the match is canceled entirely with no rescheduled makeup game, Polymarket resolves the Belupo win and Vukovar win markets to NO and the Draw market to YES. Kalshi's interpretation of cancellation is not explicitly stated but would likely follow similar logic.
Resolution Source Hierarchy: Primary source is official HNL statistics. If official statistics are not published within 2 hours after match conclusion, both platforms fall back to consensus of credible reporting sources.
Timing:
Resolution occurs upon official publication of match statistics by HNL or, if unavailable within 2 hours after match conclusion, upon consensus of credible reporting sources. Markets remain open if the match is postponed and close only after the match is completed and the result is officially confirmed.
