Description

In the upcoming NBA game, scheduled for March 28 at 3:00PM ET: If the Spurs win, the market will resolve to "Spurs". If the Bucks win, the market will resolve to "Bucks". 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.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue:

Polymarket and Kalshi have fundamentally incompatible resolution scopes. Polymarket markets resolve on specific game outcomes (moneyline, spread, totals, player props), while Kalshi's market resolves YES if either team wins, making it logically impossible to distinguish between outcomes and rendering it unresolvable as a prediction market.

Hero Tip:

Do not trade across these platforms expecting consistent outcomes. Polymarket offers granular, resolvable markets (e.g., Spurs moneyline, specific spreads, player performance). Kalshi's market is structurally broken—it resolves YES regardless of which team wins, so there is no NO outcome. Avoid Kalshi entirely for this event group.

Critical Divergence Points:

  • Polymarket:

    Aligned with standard sports betting logic: Polymarket offers 26 distinct, mutually exclusive markets covering moneyline (Spurs vs. Bucks), multiple spread thresholds (-16.5, -17.5, -18.5, -19.5), totals (O/U 225.5, 226.5, 227.5), first-half outcomes, and 30+ player prop markets (points, rebounds, assists). Each market resolves to a single outcome (YES or NO) based on final box score from NBA.com. Example: 'This market will resolve to Spurs if the Spurs win the game by 18 or more points. Otherwise, this market will resolve to Bucks.'

  • Kalshi:

    Outlier: Kalshi provides a single binary market with a logical contradiction. The resolution rule states 'If Milwaukee wins...then the market resolves to Yes' AND 'If San Antonio wins...then the market resolves to Yes.' This means the market resolves YES in all possible outcomes (either team winning), leaving no NO resolution path. This violates basic binary market structure and makes the market unresolvable.
