Citadel securities (the largest retail market maker, this is the company front-running every single one of your trades through PFOF if you use a "free" broker like Robin Hood)
Citadel LLC (the hedge fund)
Both part of Citadel the mother ship. All owned by 1 man (who like Madoff owns a hedge fund and a market maker, but unlike Madoff actually seems to execute trades with his hedge fund).
Kind of old, but still relevant (not much changed since then). The same documentary makers are working on a new one that I believe will come out this year. There's tons of info to find online if you Google any of those terms in my rant from the previous comment as well.
PS: those are just tips of multiple icebergs, there's more.

1 man who also happens to be the top GOP donor (what could he possibly want in return?): https://www.cnbc.com/2022/10/07/citadels-ceo-ken-griffin-bec...
