Theoretically, being a SME means having an edge with which one can extract money. Agree or disagree? Why?

So what is the rational reason someone who isn't a subject matter expert (assuming that's what you mean by SME) to bet in prediction markets? The platforms appear to be marketed to the general public to be used casually as a way to make quick money.

Someone who is a "subject matter expert" (and given how specific many of these predictions are, being an expert usually means you are an insider with non-public information) can indeed make money as long as a bunch of idiots with worse information place bets thinking they know the outcome. This is considered to be a crime when done with other securities.

Disagree. I don’t need to be a subject matter expert on the environment or fire risks to profit from a wildfire prediction market. I need enough money to buy a pack of cigarettes.

EDIT: I suppose I also need to be able to purchase the “shares” in the “market”
