I have been searching the internet but was unable to find data of the following form:
prediction of events for which we already know the outcome (i.e. markets that have already closed)
data for each individual participant's prediction (1 data point is enough, does not have to be historical)
I tried several sites, IEM, ideosphere.com, etc, however, the problem here is that there's no data on individual predictions.
Does anyone have an idea where I could obtain such data?
p.s. it doesn't have to be data from prediction markets, it could also be expert predictions for example.
