If I live in a country that is under threat of being attacked by U.S. it is nice to have a website where I can look to get a reasonable probability that the attack happens
If the odds sit at 97% NO for weeks or months, then 3 hours before the invasion an insider makes their play, you would have to be constantly monitoring this market, interpret that spike correctly as an insider trade, and be able to, in that very short amount of time, take actions that change the outcome for you, personally.
Doesn't seem like much of an upside to me.
