Kalshi settles on goal-differential thresholds (>1.5 or >2.5 goals), while Polymarket settles on binary match outcomes (win/loss/draw). The platforms use fundamentally different resolution scopes: Kalshi requires specific margin thresholds, whereas Polymarket resolves on simple match result.
Hero Tip:
If you bet on Kalshi, your YES outcome requires a team to win by a specific goal margin (>1.5 or >2.5 goals). On Polymarket, betting YES on Southampton or Arsenal win resolves YES for any victory, regardless of margin. A 1-0 Southampton win resolves YES on Polymarket but NO on all four Kalshi markets. Conversely, a 2-0 Arsenal win resolves YES on Kalshi market #4 but also YES on Polymarket's Arsenal win market—outcomes may diverge significantly depending on final scoreline.
Critical Divergence Points:
Kalshi: Outlier: Settles on goal-differential thresholds across four separate markets, each tied to a specific margin requirement. Market #1 resolves YES if Southampton wins by >2.5 goals; #2 if Arsenal wins by >1.5 goals; #3 if Southampton wins by >1.5 goals; #4 if Arsenal wins by >2.5 goals. Resolution is based on 'after 90 minutes plus stoppage time (does not include extra time or penalties)'.
Polymarket: Distinct stance: Settles on binary match outcomes (Southampton win, Arsenal win, or draw) with no goal-margin thresholds. Three separate markets resolve YES/NO based solely on which team wins or if the match ends level. Resolution is based on 'the outcome within the first 90 minutes of regular play plus stoppage time' and uses official FA statistics or credible reporting consensus within 2 hours of conclusion.
