It's an empirical fact that smart people can predict things by doing research. See Tetlock's book Superforecasting.

I've been doing it profitably myself for almost 10 years now. I have zero special inside knowledge, and no access to any other non-public information.

> Will the US strike Iran by X date

Last year I did think the market for a strike on Iran was significantly underpriced given the information and conditions within a specific frame of time.

I don't think every smart person can just pop into prediction markets and print money, but I know many smart people who are long-term winners. I also don't try to knock people as degenerate when they have genuine talent.

You haven't been profitable for 10 years on prediction markets and you being profitable doesn't mean anything in regards to insiders or the rigging of a market.
