Description

This event group covers the Bundesliga match between 1. FC Heidenheim 1846 and Bayer 04 Leverkusen scheduled for March 21, 2026 at 10:30 AM ET.

All markets resolve based on the official final score within 90 minutes of regular play plus stoppage time.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi and Polymarket use different threshold interpretations for total goals markets. Kalshi offers markets at 1.5, 2.5, 3.5, and 4.5 goals (resolving YES if combined score exceeds these thresholds), while Polymarket uses 1.5, 2.5, 3.5, and 4.5 but with different outcome mappings: Polymarket's O/U 3.5 resolves Over at 4+ goals, O/U 2.5 resolves Over at 3+ goals, and O/U 4.5 resolves Over at 5+ goals, creating misalignment on what constitutes the same threshold.Hero tip: If you trade the same goal threshold on both platforms, verify the exact resolution rule: Kalshi uses 'more than X goals' while Polymarket uses 'X or more goals' for Over outcomes, meaning a final score of exactly 3 goals resolves differently (YES on Kalshi O/U 2.5, but Under on Polymarket O/U 2.5). Arbitrage opportunities exist at boundary scores.

Critical divergence points:

  • Kalshi: Distinct stance: Kalshi resolves YES if combined goals are strictly greater than the stated threshold (e.g., O/U 2.5 resolves YES at 3+ goals, O/U 3.5 resolves YES at 4+ goals). Quote: 'If Leverkusen and Heidenheim collectively score more than 2.5 total goals... then the market resolves to Yes.'
  • Polymarket: Distinct stance: Polymarket resolves Over if combined goals meet or exceed a threshold that is 1 goal higher than the stated line (e.g., O/U 2.5 resolves Over at 3+ goals, O/U 3.5 resolves Over at 4+ goals, O/U 4.5 resolves Over at 5+ goals). Quote: 'This market will resolve to Over if 1. FC Heidenheim 1846 and Bayer 04 Leverkusen combine to score 4 or more goals' for the O/U 3.5 market.
