This event group covers a professional Czech Extraliga ice hockey match between HC Mlada Boleslav and HC Sparta Prague scheduled for February 22, 2026. The markets resolve based on which team wins the game, with provisions for overtime, shootouts, postponements, and cancellations.
Kalshi market contains a logical contradiction where both possible game outcomes (Sparta Prague win OR Mlada Boleslav win) resolve to Yes, rendering the market non-binary and unresolvable. Polymarket correctly implements a binary win-based structure.
Hero Tip:
Polymarket is the only tradeable market in this group. Kalshi's dual-Yes resolution is a data integrity failure that makes it impossible to distinguish between outcomes. Do not trade Kalshi until the platform corrects the resolution logic to map one team to Yes and the other to No.
Critical Divergence Points:
Polymarket:
Binary winner-take-all structure. Mlada Boleslav victory resolves to Mlada Boleslav; Sparta Prague victory resolves to Sparta Prague. Postponements keep market open; cancellations resolve 50-50. Shootout goals are counted as +1 for winner. Quote: 'If Mlada Boleslav win, the market will resolve to Mlada Boleslav. If Sparta Prague win, the market will resolve to Sparta Prague.'
Kalshi:
Contradictory dual-outcome Yes resolution. Both 'If HC Sparta Praha wins' and 'If BK Mlada Boleslav wins' are stated to resolve to Yes. This creates logical impossibility: there is no No outcome. Quote: 'If HC Sparta Praha wins... then the market resolves to Yes. If BK Mlada Boleslav wins... then the market resolves to Yes.'
