Right now, Obama is trading at 52.3 points. That is, Intrade implies that he has a 52.3 percent chance to become the next President.
Now, I happen to think that is a patently absurd price. But you don't have to take my word for it. Over at BetFair, another large UK-based gambling and futures site, you can also buy an Obama contract. But the price there is 1.62, which implies a 61.7 percent chance that Obama will become the next President.
I agree that Obama has a better than 52% chance of winning. Worth a look.
