Kalshi markets resolve on goal-margin thresholds (1.5+ or 2.5+ goal wins), while Polymarket markets resolve on match outcome (win/draw/loss). The platforms use fundamentally different resolution logic for the same underlying event.
Hero Tip:
If you trade on Kalshi, you are betting on margin of victory (large wins only). If you trade on Polymarket, you are betting on match result (any Perth win, any draw, or any Melbourne City win). A 1-0 Perth win resolves YES on Polymarket but NO on all four Kalshi markets. Ensure your position matches your intended exposure.
Critical Divergence Points:
Kalshi:
Outlier: Resolves YES only if Perth wins by more than 1.5 goals OR Perth wins by more than 2.5 goals OR Melbourne City wins by more than 1.5 goals OR Melbourne City wins by more than 2.5 goals. This means only large margin victories (2+ or 3+ goals) trigger YES; narrow wins and draws resolve NO across all four markets. Key quote: 'If Perth wins by more than 1.5 goals... then the market resolves to Yes' and 'If Melbourne City wins by more than 1.5 goals... then the market resolves to Yes.'
Polymarket:
Aligned with standard match-outcome logic: Three separate markets resolve YES if Perth wins (any margin), if the match ends in a draw, or if Melbourne City wins (any margin). Narrow wins (1-0, 2-1) resolve YES on the respective winner market. Key quote: 'If Perth Glory FC wins, this market will resolve to Yes. Otherwise, this market will resolve to No' and 'If the game ends in a draw, this market will resolve to Yes.'
