A men's college basketball game between Detroit Mercy (Titans) and Robert Morris (Colonials) scheduled for March 9, 2026 at 9:30 PM ET. Markets cover moneyline, spread, and total points outcomes across Polymarket and Kalshi platforms.
Kalshi and Polymarket use different market structures and threshold definitions for the same game. Kalshi offers 25 granular spread-based binary markets with exclusive thresholds (>X points), while Polymarket offers categorical moneyline, specific spread markets with inclusive thresholds (X or more points), and total points markets. The spread thresholds differ between platforms (-5.5 on Kalshi vs -5.5 and -4.5 on Polymarket).
Hero Tip:
Kalshi's 25 markets are highly redundant and create settlement complexity. Use Polymarket's moneyline as the primary truth source for winner determination. For spread betting, note the exclusive vs inclusive threshold difference: Kalshi resolves on >1.5 points while Polymarket resolves on 2+ points (or 6+ for -5.5 spread). Confirm the exact final score including overtime before settlement.
Critical Divergence Points:
Kalshi: Offers 25 separate Yes/No binary markets covering all possible spread outcomes from >1.5 to >20.5 points for both teams. Uses exclusive threshold language (more than X points). Example: If Detroit Mercy wins by more than 1.5 points, market resolves Yes; if by exactly 1.5 or less, resolves No.
Polymarket: Offers moneyline (categorical winner), two spread markets at -5.5 and -4.5 with inclusive thresholds (6+ or 5+ points respectively), and three Over/Under total markets (146.5, 147.5, 148.5). Example: Robert Morris -5.5 resolves to Robert Morris if they win by 6 or more points; otherwise Detroit Titans.
