PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's market resolves YES for any outcome (both TCU win and Duke win trigger YES), creating a logical contradiction that makes the market fundamentally unresolvable. Polymarket offers multiple distinct markets with proper binary logic (moneyline, spreads, totals) that resolve correctly based on game outcome.Hero tip: Avoid Kalshi's market entirely—it is logically broken and will resolve YES regardless of the actual game result. Trade only on Polymarket's markets, which have clear, mutually exclusive outcomes (Duke wins by X points, TCU wins, Over/Under totals). If you hold Kalshi YES, you will receive payout regardless of outcome; if you hold Kalshi NO, you will lose regardless of outcome.

Critical divergence points:

  • Kalshi: Outlier: Market resolves YES if TCU wins OR if Duke wins—both outcomes trigger YES resolution, violating binary market logic. Quote: 'If TCU wins the TCU at Duke men's college basketball game originally scheduled for Mar 21, 2026, then the market resolves to Yes. If Duke wins the TCU at Duke men's college basketball game originally scheduled for Mar 21, 2026, then the market resolves to Yes.' This creates a guaranteed YES outcome regardless of actual game result.
  • Polymarket: Aligned with sound market design: Offers multiple properly constructed binary markets including moneyline (TCU vs. Duke with mutually exclusive outcomes), spread markets (Duke -5.5 through -21.5 with clear thresholds), and over/under totals (137.5 through 149.5 with distinct point thresholds). Quote: 'This market will resolve to "Duke Blue Devils" if the Duke Blue Devils win the game by 12 or more points. Otherwise, this market will resolve to "TCU Horned Frogs."' Each market has exactly one winning outcome per game result.
