I've been following poly market for a while now, polls can be fixed (choosing the demographic to do it the easiest one) and they are a photograph of a moment past 

Prediction market are new and they react live, meanwhile not all the agents of the market have a vote, the poly market bag is already in the $2bi mark ‼️ now it's showing odds and lines and in my view ain't no more about voting and more about money 💰 

But even in the prediction market and knowing how the election goes, if you look closer to swing states there's still battlegrounds for both sides.

But IMO this is the first election with heavy betting and it will shows if it's a better indicator for the following disputes
