Online prediction market Intrade enabled people to put money where their mouth is. Even the success of their own business was subject to an online bet with the following prediction: 'Intrade.com to be open for business on 31 Dec 2011'.
Interestingly, this was the last version of a regularly returning prediction. In March 2013, Intrade.com appeared to be offline and 'dead', according an article in the Washington Post.
