This event group covers a professional Czech Extraliga ice hockey match between Mountfield HK and HC Vitkovice scheduled for February 25, 2026. Markets on Polymarket and Kalshi are tracking the winner of this single game, with resolution based on final score including overtime and shootout outcomes.
Kalshi market contains a logical contradiction where both possible game outcomes (Vitkovice win and Mountfield HK win) are mapped to the same resolution state (Yes), making the market unresolvable and creating a data integrity failure.
Hero Tip:
This is a critical market design flaw on Kalshi. Both winning outcomes cannot resolve to Yes—there must be a No outcome. Request immediate clarification from Kalshi whether the Mountfield HK condition should resolve to No, or if the market description is incomplete. Polymarket's binary structure is sound and resolvable. Avoid trading Kalshi until the contradiction is formally corrected.
Critical Divergence Points:
Polymarket: Clean binary winner-take-all design. Mountfield HK win resolves to Mountfield HK; Vitkovice win resolves to Vitkovice. Postponement keeps market open; cancellation without makeup resolves 50-50. Shootout adds one goal to winner's score for resolution purposes. Key Quote: If Mountfield HK win, the market will resolve to Mountfield HK. If Vitkovice win, the market will resolve to Vitkovice.
Kalshi: Logically incoherent YES/NO structure. Both Vitkovice win and Mountfield HK win are stated to resolve to Yes, leaving no valid path to No resolution. This creates an unresolvable market. Key Quote: If HC Vitkovice wins... then the market resolves to Yes. If Mountfield HK wins... then the market resolves to Yes.
