Contracts like this one have settled YES 10.4% of the time, and the crowd is charging 5c. Based on 48 settled other markets in the 0-9c band, priced about a day before their events. After the 1c taker fee, that leaves about 4c 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 other curve it came from.

What history says about this price

Across our settled record, markets priced near 0–9¢ have gone on to settle YES 14% of the time (n=146). The price implies 5%, so historically this band has come in about 9 points higher than the sticker. That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
