Description

This event group covers the outcome of a single NPB (Nippon Professional Baseball) game between the Yokohama BayStars and Yomiuri Giants scheduled for June 26, 2026 at 5:15 AM EDT. Markets on Kalshi and Polymarket are pricing the same underlying sporting event but with materially different resolution mechanics and outcome spaces.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's resolution logic contains a logical contradiction: both possible game outcomes (Giants win and BayStars win) are mapped to the same resolution state (Yes), making the market fundamentally unresolvable and creating data integrity failure. Polymarket uses a proper binary outcome space with explicit tie/cancellation handling.Hero tip: Kalshi's market cannot be fairly settled as currently written. Polymarket is the only resolvable market for this event. Avoid trading Kalshi until platform corrects the resolution criteria to distinguish between the two teams' outcomes.

Critical divergence points:

  • Kalshi: Binary YES/NO market where both team-win scenarios resolve to YES. This is a logical contradiction that makes settlement impossible. Key Quote: 'If Yomiuri Giants wins...resolves to Yes. If Yokohama DeNA BayStars wins...resolves to Yes.'
  • Polymarket: Categorical outcome market resolving to team name (Yokohama BayStars or Yomiuri Giants) with explicit 50-50 resolution for tie, cancellation, or no make-up game. Key Quote: 'If the Yokohama BayStars win, the market will resolve to Yokohama BayStars. If the Yomiuri Giants win, the market will resolve to Yomiuri Giants.'
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.
