Trading of publicly listed stocks happen on stock exchanges, Nasdaq is one of these. They make money by charging fees for companies to publicly list stocks. But also charging fees from anyone who wants to directly trade there. Say stock brokers who allow smaller customers to trade via services these brokers offer.

So Nasdaq owns the company which facilitates this trading of stocks. But they also own the company which says what are 100 most important companies on that market.

Now they changed rules to get big new most likely popular stock on their market. This could at least maybe get some new brokers in. Or make them in general more desirable market to be connected to and thus get fees.

I am not just sure if there is even more fees in some part I don't know there...

Contrary to the sp500 that only earns money from listing companies but not when people buy shares, right ?

That's a serious conflict of interest.
