The vision of people who believe strongly in prediction markets is, for instance, that you could have a prediction market for "if we replace our CEO, will our revenue be higher in X years than the counterfactual where we kept our CEO?", and use that as input to the CEO's performance evaluation. Because people have to put their money where their mouth is, if you believe that a market is incorrectly priced, you can go make money on it.

Whether this works in practice remains to be seen, but it's an interesting vision.
