Unified Resolution Criteria (Consistent across platforms)
Both Kalshi and Polymarket resolve based on the official outcome of the FC Köln vs. Borussia Mönchengladbach match scheduled for March 21, 2026, considering only the result after 90 minutes plus stoppage time, with the same primary source (official governing body statistics or credible consensus reporting).
Primary resolution logic:
Official Bundesliga statistics as recognized by the governing body; if unavailable within 2 hours of match conclusion, credible reporting consensus.
Core resolution logic:
Market resolves based on the final score after 90 minutes of regular play plus stoppage time (extra time and penalties are excluded).
Kalshi markets resolve YES if Köln wins, YES if a tie occurs, or YES if M'gladbach wins (all three outcomes trigger YES, making this a tautological market).
Polymarket markets resolve YES for Köln win, NO otherwise; YES for M'gladbach win, NO otherwise; and YES for a draw, NO otherwise (three separate binary markets covering all outcomes).
If the match is postponed, both platforms keep markets open until the match is completed.
If the match is canceled with no make-up game, Kalshi markets resolve YES (all outcomes covered) and Polymarket draw market resolves YES, while Polymarket win markets resolve NO.
Edge cases & Clarifications:
Match Postponement: Both platforms keep their markets open until the match is completed, regardless of postponement duration.
Match Cancellation Without Makeup: Kalshi's tautological structure means all three markets resolve YES. Polymarket's draw market resolves YES; Polymarket's win markets resolve NO.
Official Statistics Delay: If Bundesliga does not publish final statistics within 2 hours of match conclusion, both platforms permit resolution based on credible reporting consensus.
Timing:
Resolution occurs upon official Bundesliga announcement of the final match result, or within 2 hours after match conclusion via credible reporting if official statistics are delayed.
