Southampton FC vs. Derby County FC

Unified Resolution Criteria (Consistent across platforms)

Core resolution logic:

• Market resolves based on the match outcome after 90 minutes of regular play plus stoppage time only (no extra time or penalties).
• Three mutually exclusive outcomes are possible: Southampton wins (YES on Polymarket Southampton market, YES on Kalshi market 1), Draw (YES on Polymarket draw market, YES on Kalshi market 2), or Derby wins (YES on Polymarket Derby market, YES on Kalshi market 3).
• Exactly one outcome will occur and resolve to YES; all other markets in the group resolve to NO.
• If the match is postponed, resolution is delayed until the match is completed.
• If the match is canceled entirely with no make-up game, Polymarket draw market resolves YES (no winner determined), while Polymarket Southampton and Derby markets resolve NO; Kalshi markets remain unresolved or follow similar cancellation protocol.

Edge cases & Clarifications:

• Match Postponement: If the April 11, 2026 match is postponed, both platforms keep markets open until the rescheduled match is completed and resolved according to the same 90-minute-plus-stoppage-time rule.
• Match Cancellation: If the match is canceled entirely with no make-up game, Polymarket's draw market resolves YES (treating cancellation as 'no winner'), while Southampton and Derby win markets resolve NO. Kalshi's treatment of cancellation is not explicitly specified but should follow similar logic.
• Source Timing: Primary resolution source is official EFL statistics. If EFL does not publish final statistics within 2 hours of match conclusion, credible reporting consensus becomes the authoritative source on both platforms.
