Option Trading sites for Sporting Events, Elections, etc

Help me out with those sites that facilitate trading in options for sporting events, etc. Can’t seem to remember them, I think they are mostly in Ireland. Trying to see what the sentiment out there is for the Olympic 2016 outcome…I thought Rio for sure, but now I am hearing OBama was tipped off of Chicago win…
