Issue:
Kalshi uses ambiguous "over X.5" phrasing while Polymarket provides explicit goal-count thresholds. Both platforms reference the same game and NHL.com as source, but the linguistic difference creates minor interpretation risk at boundary scores.Hero Tip:
Align on Polymarket's explicit numeric thresholds: 5+ goals for 4.5 line, 6+ for 5.5, 7+ for 6.5, 8+ for 7.5. Kalshi's "over X.5" maps directly to these same values. Shootout rule is consistent: add 1 goal to winning team's score. Confirm final score from NHL.com within 1 hour of game end.Critical Divergence Points:
- Kalshi: Five separate markets using "over X.5" language (over 3.5, 4.5, 5.5, 6.5, 7.5 total combined goals). Resolves to Yes if threshold exceeded. Language does not explicitly state whether 3.5 means >3.5 or >=4, creating minor ambiguity.
- Polymarket: Four O/U markets with explicit goal counts: O/U 7.5 = 8+ goals Over; O/U 6.5 = 7+ goals Over; O/U 5.5 = 6+ goals Over; O/U 4.5 = 5+ goals Over. Unambiguous numeric thresholds. Also includes moneyline (Bruins vs Flyers winner) and spread markets (Bruins -1.5, Flyers -1.5).
