I thought the point of them is they are “truth machines” they give a financial incentive for the insider class to essentially share what they know.
The benefit to those outside the insider class are that we now have a better idea of the potential outcome.
How can anyone differentiate an insider bet from a normal one enough to actually make use of it?
This is what their argument is, and personally I think it's a pretty good one. But the main issue is that retail is getting fleeced and lives are being destroyed by gambling, so non-professional investors should not be able to use it. Imo, the upside (some fisherman with insider knowledge betting on the Strait of Hormuz) doesn't outweight the downside (a large-scale societal gambling epidemic[1]).
