Contracts like this one have settled YES 57.5% of the time, and the crowd is charging 50c. Based on 219 settled sports markets in the 50-59c band, priced about a day before their events. After the 2c taker fee, that leaves about 6c of edge per contract, if this market behaves like the ones we measured.

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.
