Kalshi settles on goal-differential thresholds (markets resolve YES if either team wins by >1.5 or >2.5 goals), while Polymarket settles on simple win/loss/draw outcomes. The platforms use fundamentally different resolution scopes: Kalshi requires specific margin thresholds, whereas Polymarket resolves on any Porto win, any Nottingham win, or a draw.
Hero Tip:
If you bet on Kalshi, your YES outcome requires a decisive margin (>1.5 or >2.5 goals); a 1-0 or 1-1 result will resolve NO on all four Kalshi markets. On Polymarket, a 1-0 Porto win resolves YES on the Porto win market and NO on the draw/Nottingham markets. Do not assume Kalshi and Polymarket outcomes will align—they measure different things.
Critical Divergence Points:
Kalshi: Outlier: Kalshi uses goal-differential thresholds as the sole resolution criterion. All four markets resolve YES only if Porto wins by >2.5 goals, Nottingham wins by >1.5 goals, Porto wins by >1.5 goals, or Nottingham wins by >2.5 goals respectively. Matches with margins of ≤1.5 goals resolve NO on all markets. Key quote: 'If Porto wins by more than 2.5 goals... then the market resolves to Yes' and 'If Nottingham wins by more than 1.5 goals... then the market resolves to Yes.'
Polymarket: Outlier: Polymarket uses simple binary outcomes (Porto win YES/NO, Nottingham win YES/NO, draw YES/NO) with no goal-differential thresholds. A 1-0 Porto victory resolves YES on the Porto win market regardless of margin. Key quote: 'If FC Porto 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.'
