**No perfect game has occurred in the 2026 MLB regular season, which concluded September 27, leaving the total at 24 for all time—the last one thrown by Domingo Germán in 2023.** With the ALCS and World Series still ahead, the 77.8% implied probability on “No” reflects the extreme rarity of the feat amid shortened starts, heavy bullpen usage, and matchup-driven pitching. Only one postseason perfect game exists in MLB history (Don Larsen, 1956), and the remaining schedule offers limited opportunities for a starter to face 27 consecutive batters without a baserunner. Recent trends show declining complete games and no-hitters, reinforcing trader consensus that another perfect outing is unlikely before the season ends.
