For nearly 10 years, I’ve been playing the Hollywood Stock Exchange. Basically it’s a prediction market based on the box office returns of movies. It’s been a pretty good indicator over the years, but the income model was based nearly totally on ad revenue. A few months ago, they announced a complete site overhaul, ostensibly to “update” to the Web 2.0 model. It must not have been very successful, given its short life and eventual reversion to the “old” site.
Anyway, the 2.0 idea has been abandoned in favor of an even more major step forward: the Cantor Exchange. Named after HSX’s parent company Cantor Fitzgerald, it will be similar to the game format except you’ll be able to invest with real money. Details are sketchy as to the actual implementation, but I expect I’ll be playing around with it a little.
