The military strikes on June 21st didn't cause the earlier Polymarket resolutions for June 19th-20th; those markets simply resolved as "No Outcome" because nothing happened on those specific days.
It's like saying a job offer today retroactively makes yesterday's interviews irrelevant — that's not how it works.
Each day's market has its own finite timeframe, and the outcome is based on what actually occurred within that period, not some future event.
You're confusing a sequence of events with a direct trigger; time and market resolutions are pretty clear about that.
