This is not quite as interesting as it sounds. Ie, they're not using Tipjoy as a way to have real-money prediction markets (which would be wonderful and, sadly, illegal in the US). I wonder if an unspoken agreement could be reached among like-minded bettors that all debts in inkles get settled via tipjoy tips in dollars. If you could also tip people from your inkles balance then this might be easy enough to establish (even without Inkling officially condoning it).
