How can a strike on June 21st possibly make a market from June 19th and 20th resolve with a "No outcome"? That's just glossy hype pretending a past event needs future confirmation.
If nothing happened on those specific days, the market for those days resolves as "No" immediately, because that’s the actual outcome for that period.
It's like saying if I didn't get my visa stamped yesterday, and I get it today, then today's stamp somehow retroactively caused yesterday's 'no stamp' status.
What actually changes is that markets close based on facts within their timeframe, not on what happens later; otherwise, nobody would trust the cash in those Polymarket accounts.
