MARKETS LIKE THIS SETTLED AT

88¢

Contracts like this one have settled YES 87.8% of the time against a 88c price, which is close enough to fair that the 1c fee eats whatever is left. Based on 41 settled other markets in the 80-89c band, priced about a day before their events.

This is what this kind of contract has been worth, not a forecast for this one: a band average does not know what is happening in the news. See the Fair Value Board for every market scored this way, or the other curve it came from.

What history says about this price

Across our settled record, markets priced near 80–89¢ have gone on to settle YES 83% of the time (n=367). The price implies 80%, so historically this band has come in about 3 points higher than the sticker. That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
