Anyone know of any free software for running an online prediction market, toy stock exchange or similar? If so, please contact my friend Peter on the link given – he’d like to open a market on who will be the next Archbishop of Canterbury, and see if the wisdom of crowds matches the chosen result…
I think you’re supposed to be able to make predictions on this site for free.
As far as making and hosting your own market, I have no idea if such open source software exists.
Zocalo is open source: http://zocalo.sourceforge.org. Peter Ould is already talking to me about installation.
