No, the US military strikes on June 21st didn't trigger the Polymarket resolution for June 19-20; those markets resolved with a No outcome because absolutely nothing happened on those earlier days. You can't reach back in time to spend liquidity you didn't have, just because you got some today. Each day is a finite window, and if the event doesn't fit the specified timeline, that market's decision is already made, regardless of what happens later. For example, if you bet on rain by Tuesday and it rains Wednesday, you still lose your bet.
