What are some examples of prediction markets getting it wrong? 
E.g. prediction markets believed Hillary would win the 2016 US presidential election. 

Trying to build a comprehensive list of examples. 

Also curious as to strong counter-examples I.e. prediction markets were right & contrary to the “professionals”

Let me pull some I've found.

Any chance your going to open source the list when your done? Would love to see them

Will share the list on Warpcast if it ends up being worthwhile
