This is a common take on "inside information", but for most people this opinion is totally unaligned with their own goals. The people who benefit from "no insider trading" in any market, are a small group of active traders, some institutional, some not.

For literally everyone else, insider trading is a net win. Insider trading improves price discovery. If you passively invest then you benefit from the price being more accurate when whatever fraction of your paycheck goes into the market.

I don't know your own situation, maybe you are one of those few traders who needs information to spread a certain way in order to make money. For everyone else, don't be fooled into promoting an idea against your own interests.

This is talking about using Compound AI (product I'm working on) to query Polymarket data, including finding insiders, just as a fun example analysis you could do.

Often you need a well-calibrated probability of a future event to feed into some other analysis, and Polymarket is pretty great for that. An example is how much insurance (hedge) to buy for some disastrous event.
