O.J Simpson guilty of at least one Las Vegas robbery charge? Barack Obama to win 2008 US Presidential Election? Bird Flu to be confirmed in the USA on/before March 31st, 2008? Earthquake measuring 9.0 or more on Richter scale to occur anywhere on/before December 31st, 2008?

So what's this all about.  I stumbled upon a site that allows you to trade these events and more.  If you think the likelihood of this happening is good, go long.  If not, go short.  

Right now, the chances of the US economy going into recession this year are 63.2%, down from a high of 75% back in mid-January.  I don't know if this site would be of any use to me but it may be a useful indicator to gauge investor sentiment.
