PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental market structure mismatch - Kalshi's binary design cannot properly handle tie/cancellation scenarios while Polymarket has explicit 50-50 resolution rulesHero tip: Avoid trading the Kalshi market due to its flawed resolution structure. Polymarket provides proper resolution mechanics including 50-50 splits for ties/cancellations. If participating, use Polymarket for accurate settlement.

Critical divergence points:

  • Polymarket: Resolves to specific team names; 50-50 split for ties/cancellations. Quote: If game is canceled entirely...this market will resolve 50-50
  • Kalshi: Binary Yes/No market that resolves Yes for either team win, with no provision for ties/cancellations. Quote: If Tohoku Rakuten Golden Eagles wins...market resolves to Yes
