The resolution of prediction markets for June 19th and 20th with a 'No' outcome doesn't automatically get dictated by later events on June 21st.
Would we re-enter this thinking that a later event causes a prior outcome, if we hadn't already sunk time linking them?
It’s more likely the 'No' simply reflected that nothing happened on those days, irrespective of what came after; for example, if there was no credible intelligence, markets often just settle without activity.
