The utility is a fairly robust signal about the probability of certain events occurring. It's pretty helpful for grounding your beliefs about the world (in certain domains).
For example, I had a lot of people ask me about the Hantavirus and if it was worth worrying about. I didn't have to do any research other than look at the various prediction markets and see them all at 5-10% to determine it was probably a nothingburger. Much quicker than having to parse a bunch of fearmongering news reports and such.
