Intro

This market tracks the first five innings of an MLB game between the Detroit Tigers and Houston Astros scheduled for June 16, 2026 at 8:10 PM ET. The consensus probability across Polymarket, Kalshi, and Predict shows the Houston Astros (-1.5) spread at 50.0%, with the Detroit Tigers (-2.5) spread also at 50.0%. Resolution will be determined by Official MLB final statistics from MLB.com box scores and official records, or by consensus of credible reporting if official statistics are not published within 24 hours of game conclusion. Watch how each team's bullpen performs during the first five innings, as this period often determines early-game momentum and spread outcomes.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All three platforms (Polymarket, Kalshi, Predict) apply identical resolution logic: official MLB statistics as primary source, 24-hour publication window, postponement handling, 50-50 tie/cancellation resolution, and clearly defined thresholds for each market type.Primary resolution logic: Official MLB final statistics (MLB.com box scores and official records); consensus of credible reporting if official statistics not published within 24 hours of game conclusion

Core resolution logic:

  • Moneyline (Winner): Resolves to team with higher final score after 9 innings; 50-50 if tied or game canceled with no makeup
  • Spreads (Full Game): Resolves based on final score margin; Houston Astros (-1.5) wins if ahead by 2+ runs, otherwise Detroit Tigers wins; ties resolve to the underdog side
  • Spreads (First 5 Innings): Resolves based on score differential at end of 5th inning only; ties resolve to underdog side
  • Over/Under (Full Game): Over 8.5 resolves Yes if combined runs >= 9; Under if < 9
  • Over/Under (First 5 Innings): Thresholds vary by market (2.5, 3.5, 4.5, 5.5, 6.5); Over resolves Yes if combined runs meet or exceed threshold; Under if below
  • First Inning Scoring: Yes if any run scored in 1st inning by either team; No if scoreless
  • Extra Innings: Yes only if play begins in 10th inning or later; No if game completes in 9 innings; 50-50 if game ends in tie before extra innings

Edge cases & clarifications:

  • Game Postponement: All markets remain open until the game is completed. Check Houston Astros home schedule on MLB.com for makeup game date.
  • Game Cancellation (No Makeup): All markets resolve 50-50 if game is canceled entirely with no makeup game scheduled.
  • Tied Game After 9 Innings: Moneyline resolves 50-50. First 5 innings spreads resolve to underdog. Extra innings market resolves 50-50 if no play begins in 10th inning.
  • Official Statistics Delay: If MLB does not publish final statistics within 24 hours of game conclusion, resolution uses consensus of credible reporting (e.g., ESPN, MLB.com news, official team announcements).
  • Kalshi Run Threshold Markets: Kalshi markets resolve Yes if either team reaches specified run threshold (2+, 3+, 4+, 5+, 6+, 7+, 8+ runs). These are independent Yes/No markets, not comparative.
Timing: Resolution occurs within 24 hours after official game conclusion (final out recorded). For postponed games, resolution timing resets to 24 hours after the makeup game concludes. First 5 innings markets resolve after the 5th inning is completed, even if game is later postponed or extended.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.
