The resolution of a Polymarket for June 19th and 20th to 'No outcome' has absolutely nothing to do with US military strikes happening on June 21st; that’s just common sense.
If something didn't happen on those specific days, it didn't happen, and that's the only condition that matters for that market.
Linking a later event to an earlier 'no' simply introduces unnecessary drawdown in understanding the market's clear rules.
It’s like saying my milk went off last Tuesday because I bought fresh milk this Saturday; completely separate.
