The previous claim says Polymarket markets from June 19th and 20th resolved as 'No' due to US military strikes on June 21st, but that doesn't quite add up. Those earlier markets resolved because no military action happened on those specific dates.
It's like saying not buying groceries last Tuesday was caused by deciding to buy new shoes on Thursday; the events aren't linked retrospectively.
The markets for June 19th and 20th would have resolved 'No' regardless of what happened later, because their conditions were met by the absence of an event at that time.
