Many thanks to the awesome Damon Root for this great interview. Here’s a summary:

Since it launched in November 2009,FantasySCOTUS.net has attracted nearly 5,000 players and become the toast of the legal world. The brainchild of 25-year-old Josh Blackman, a graduate of George Mason University Law School and a teaching fellow at Pennsylvania State University’s Dickinson School of Law, Fantasy SCOTUS asks players to predict the outcome of Supreme Court decisions based on their knowledge of the Constitution, legal precedent, and the proclivities of various Supreme Court justices. The game is a cousin to the thriving world of prediction markets, where participants bet on real-world outcomes in everything from elections to the Academy Awards.
