In this example from your proposal:
One market asks, “what will The DAO token value be at a time in the future if we implement this proposal” and the other asks ““what will The DAO token value be at a time in the future if we do not implement this proposal.”
What happens to the dead end vote? What I means is if you put in a vote for the value of the token if we do not implement the proposal, then the proposal is implemented, then accuracy cannot be gauged - so is the money wagered simply returned?
If the money is returned then isn't that very easy to game: If I want to get my own proposal implemented then instead of voting that it will increase the dao price if implemented, I just put lots of money into betting that the dao price will be very low if the proposal isn't implemented; this makes accepting the proposal relatively more appealing so the proposal is implemented, but I haven't risked any of my funds to manipulate the market because I just get a refund.
