Unified Resolution Criteria (Consistent across platforms)
All markets across Polymarket and Kalshi resolve based on the official final score from jleague.jp for the match scheduled April 24, 2026, considering only the first 90 minutes of regular play plus stoppage time, with consistent postponement and cancellation protocols.
Primary resolution logic:
Official final score published on jleague.jp (J-League official statistics)
Core resolution logic:
Spread markets (Kashima -1.5, Kashiwa -1.5, Kashima -2.5, Kashiwa -2.5) resolve based on the goal differential: the named team must win by the specified margin or greater to resolve YES; otherwise NO.
Over/Under markets (O/U 1.5, 2.5, 3.5, 4.5) resolve YES if combined goals meet or exceed the threshold (2, 3, 4, 5 respectively); otherwise NO.
Both Teams to Score resolves YES if both teams score at least one goal each; NO if either team scores zero.
Kalshi match outcome markets (Tie, Kashiwa win, Kashima win) each resolve YES if that specific outcome occurs after 90 minutes plus stoppage time.
Resolution uses only official statistics within 90 minutes of regular play plus stoppage time; extra time and penalties are excluded.
Edge cases & Clarifications:
Game Postponement: If the match is postponed, all markets remain open until the game is completed and the official final score is published on jleague.jp.
Game Cancellation: If the game is canceled entirely with no make-up game scheduled, all Polymarket markets resolve 50-50; Kalshi markets would similarly resolve based on no outcome occurring.
Incomplete Match: If the game is started but not completed within 90 minutes plus stoppage time, resolution is based on the official final score published by jleague.jp for the portion played.
Secondary Resolution Source: If jleague.jp does not publish final match statistics within 2 hours after the event's conclusion, a consensus of credible reporting may be used as fallback.
Timing:
Resolution occurs upon official publication of the final score on jleague.jp, with a 2-hour window for official statistics before secondary sources are considered.
