Divergence Detected
Issue:
Kalshi presents a binary moneyline-only market while Polymarket offers 84 granular markets (moneyline, multiple spread tiers, multiple total tiers, first-half variants, and player props). Kalshi's resolution logic for postponement, cancellation, and ties is absent; Polymarket explicitly addresses all three.Hero Tip:
Treat these as separate event ecosystems. Polymarket is suitable for precise threshold trading (spreads, totals, props); Kalshi is a simple binary bet on game outcome. Do not assume Kalshi's binary Yes resolves identically to Polymarket's moneyline—verify Kalshi's handling of postponement and cancellation before trading. If the game is postponed or cancelled, Polymarket has explicit 50-50 fallback; Kalshi does not.Critical Divergence Points:
- Polymarket: 84 distinct markets covering moneyline (Nets vs Celtics), spreads (Celtics -16.5, -17.5, -18.5 with corresponding point thresholds), totals (O/U 206.5, 207.5, 208.5, 209.5, 210.5), first-half moneyline, first-half spreads (Celtics -9.5, -10.5), first-half totals (O/U 107.5, 108.5), and 60+ player props (points, rebounds, assists for 15+ players). All resolve via official NBA.com box score. Postponement keeps markets open; cancellation with no makeup resolves 50-50. Ties resolve per specific market rules (e.g., spread ties resolve to Nets, moneyline ties resolve 50-50 implicitly).
- Kalshi: Single binary market: 'If Boston wins the Brooklyn at Boston professional basketball game originally scheduled for Feb 27, 2026, then the market resolves to Yes. If Brooklyn wins the Brooklyn at Boston professional basketball game originally scheduled for Feb 27, 2026, then the market resolves to Yes.' No explicit resolution logic for postponement, cancellation, ties, or overtime. Resolution source and timing undefined.
