"It wouldn’t be surprising if participation levels over time were low for prediction markets. Companies can’t really pay you in anything but trinkets, or it becomes online gambling. In this upstanding country that’s illegal. Further, as Mark Turrell pointed out to me, any prediction market works by continual trading based on new information. The participants in prediction markets would have to be pretty highly motivated to keep going back to the site and placing new bets."
