Polymarket and Kalshi offer non-overlapping market structures for the same match. Polymarket provides comprehensive spread, over/under, and prop markets with explicit slstat.com sourcing. Kalshi provides only four yes/no margin markets with no stated resolution source, creating incomplete coverage and sourcing ambiguity.
Hero Tip:
Polymarket offers superior market granularity and transparent sourcing via slstat.com. Kalshi's four markets cover only extreme margin scenarios and lack explicit resolution source documentation. Cross-platform traders should treat these as separate market ecosystems rather than direct hedges. Confirm Kalshi's resolution source before settlement.
Critical Divergence Points:
Polymarket:
Comprehensive market suite: spreads at -1.5 and -2.5 for each team, over/under at 1.5, 2.5, 3.5, 4.5 goals, and both-teams-to-score. Explicit resolution source: slstat.com official final score. Scope: 90 minutes plus stoppage time only. Fallback: credible reporting consensus if slstat.com does not publish within 2 hours post-match.
Kalshi:
Four yes/no markets only: Al-Riyadh >1.5 goal margin (Yes), Al Qadsiah >1.5 goal margin (Yes), Al-Riyadh >2.5 goal margin (Yes), Al Qadsiah >2.5 goal margin (Yes). No explicit resolution source stated. Scope: 90 minutes plus stoppage time only. No fallback or consensus mechanism documented.
