Description

In the upcoming NHL game, scheduled for March 21 at 7:00PM ET: If the Islanders win, the market will resolve to "Islanders". If the Canadiens win, the market will resolve to "Canadiens". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, this market will resolve 50-50. The result will be determined based on the final score including any overtime periods and shootouts. In the event of a shootout, one goal will be added to the winning team's score for the purpose of resolution.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue:

Kalshi and Polymarket resolve on fundamentally different event types. Kalshi resolves on moneyline winner (either team winning resolves YES), while Polymarket resolves on multiple distinct markets: moneyline, over/under totals at four different thresholds, and a spread. Kalshi's market structure is logically contradictory and unresolvable.

Hero Tip:

Avoid Kalshi's market entirely — it states both 'If NYI Islanders wins...resolves YES' AND 'If MTL Canadiens wins...resolves YES', meaning every possible outcome resolves YES. This is a data integrity failure. Trade only on Polymarket's clearly defined markets (moneyline, O/U 4.5/5.5/6.5/7.5, and spread), which have coherent resolution logic.

Critical Divergence Points:

  • Kalshi:

    Outlier: Market contains a logical contradiction. Both outcomes (Islanders win OR Canadiens win) are stated to resolve YES, making the market unresolvable. The structure violates basic binary market logic and suggests a data entry error rather than a valid market definition.

  • Polymarket:

    Distinct stance: Offers five separate, well-defined markets covering different aspects of the game: moneyline (Islanders vs. Canadiens winner), four over/under total goals markets (O/U 4.5, 5.5, 6.5, 7.5), and a spread (Canadiens -1.5). Each market has clear, mutually exclusive resolution criteria with consistent postponement and cancellation rules.
