Curious if there is a way to force these companies to place bets on the predictions that they make. They say that a merger is going to do XYZ -- well, with what degree of certainty? And are you willing to take a position tied to the outcome? Because as it stands, they can make an argument it will help with consumer choice -- but that isn't the driver, it's about profits. So if the idea is to protect the consumer or benefit them, make a prediction about that and then take a position where you will get an additional payoff if you are right. If you are wrong, you'll be "fined" by having to cover the bet.
