KalshiRules
This market will resolve “Yes” if any player throws a Perfect Game in any game during the 2026 MLB season (including postseason).
- Otherwise, this market will resolve to “No”.
- A “Perfect Game” is achieved when a pitcher throws a complete game without allowing a baserunner.
- If the 2026 MLB season is cancelled, postponed after November 30, 2026, 11:59 PM ET, or it cannot be determined if a Perfect Game occurred within that timeframe, this market will resolve to “No”.
- The resolution source for this market will be official information from the MLB; however, a consensus of credible reporting may also be used.
