This event group covers the Serie A match between Cagliari Calcio and SSC Napoli scheduled for March 20, 2026. Three mutually exclusive outcomes are possible within 90 minutes plus stoppage time: a Napoli victory, a Cagliari victory, or a draw. The markets collectively capture all possible match results with consistent resolution criteria across platforms.
Unified Resolution Criteria (Consistent across platforms)
Polymarket and Kalshi both resolve based on the official match outcome (win, loss, or draw) after 90 minutes plus stoppage time on March 20, 2026, using the same primary source (official Serie A statistics or credible reporting consensus).
Primary resolution logic:
Official Serie A statistics (Lega Serie A) or consensus of credible reporting if official statistics are not published within 2 hours after match conclusion.
Core resolution logic:
Exactly one of three mutually exclusive outcomes will occur: Cagliari Calcio wins, SSC Napoli wins, or the match ends in a draw.
Each outcome is measured only within the first 90 minutes of regular play plus stoppage time (no extra time or 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 draw market resolves YES and both teams' win markets resolve NO; Kalshi's markets all resolve YES (covering all possible outcomes).
Edge cases & Clarifications:
Match Postponement: If the match scheduled for March 20, 2026 is postponed, all markets remain open and unresolved until the rescheduled match is completed.
Match Cancellation Without Makeup: If the match is canceled entirely with no make-up game, Polymarket's draw market resolves YES (treating cancellation as equivalent to a draw for resolution purposes), while Cagliari and Napoli win markets resolve NO. Kalshi's markets all resolve YES because the cancellation satisfies the condition that the match occurred (or did not occur in a way that prevents resolution).
Resolution Source Timing: Primary resolution source is official Serie A statistics. If official statistics are not published within 2 hours after match conclusion, resolution may use consensus of credible reporting (news outlets, official team sources, etc.).
Timing:
Resolution occurs immediately upon completion of the match (after 90 minutes plus stoppage time) on March 20, 2026, once the official result is confirmed by Serie A or credible reporting consensus.
