Polymarket and Kalshi diverge on market scope and resolution thresholds. Polymarket offers multiple Over/Under markets at different goal thresholds (1.5, 2.5, 3.5, 4.5) and spread markets at different goal margins (-1.5, -2.5), while Kalshi provides only two binary markets resolving on whether either team wins by more than 1.5 or 2.5 goals respectively.
Hero Tip:
If you trade on Polymarket, you have granular control over specific goal thresholds and can hedge across multiple spreads. On Kalshi, you are limited to binary win-margin outcomes. Ensure your position aligns with the platform's available markets before settlement—a Polymarket O/U 2.5 outcome may not map directly to a Kalshi binary.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket offers a comprehensive suite of markets including four Over/Under thresholds (1.5, 2.5, 3.5, 4.5 goals), four spread markets (Al Ittihad -1.5/-2.5, Al Hazem -1.5/-2.5), and a Both Teams to Score market. All resolve on official slstat.com statistics within 90 minutes plus stoppage time, with a 2-hour grace period for official publication before consensus reporting is used. Example: 'This market will resolve to Over if Al Ittihad Saudi Club and Al Hazem SC combine to score 4 or more goals in this game.'
Kalshi: Distinct stance: Kalshi provides only two binary markets: one resolving YES if either team wins by more than 1.5 goals, and another resolving YES if either team wins by more than 2.5 goals. Both markets measure outcomes after 90 minutes plus stoppage time with no extra time or penalties. Example: 'If Al-Ittihad wins by more than 1.5 goals... then the market resolves to Yes. If Al-Hazm wins by more than 1.5 goals... then the market resolves to Yes.'
