MARKETS LIKE THIS SETTLED AT

87¢

Contracts like this one have settled YES 87.1% of the time against a 87c price, which is close enough to fair that the 1c fee eats whatever is left. Based on 1,230 settled sports 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 sports curve it came from.
