For those of you who love prediction markets (a variety of which we’ve written about in the past), there’s a new site that looks to be as vast, inclusive, and user-friendly as anything I’ve seen: Predictify.

Economists Speak Out on Prediction Markets

We’ve blogged quite a bit about prediction markets. Now, some very prominent economists (including four Nobel prize winners) have come together to release a joint statement asking the U.S. government to make it easier for researchers to create them. While the statement argues the merits of prediction markets extremely cogently, and while I’m completely in […] Read More »

Comic Con and a Prediction Market for Gamers

Last weekend, I went to New York Comic Con with my 14-year-old nephew. As someone who’s never been heavily into superheroes, manga, anime, or gaming, I found it utterly fascinating.

Predicting the End of the Government Shutdown

Flip Pidot, co-founder and CEO of the American Civics Exchange, writes to let us know that the exchange has recently added cash prizes to their political prediction markets and is currently running two parallel government shutdown prediction markets, allowing for an interesting experiment:

At American Civics Exchange, we’ve just begun to implement cash prizes in our political prediction market (a sort of interim maneuver on our way to regulated exchange-traded futures).
