Robinhood has lots of problems, this is not one of them.
[edit] Forgot about fractionals where this statement is true, but that's well known/accepted?
Internalizing trades however is less of a conspiracy. Almost all US brokers do this or offer this trade routing option.
Here's the head of the SEC stating that almost all retail market orders on any broker never hit a lit exchange and are internalized: https://www.youtube.com/watch?v=wg8onYvJW3Q
Originally this was talking about "fake/not-real ownership of the underlying stock", but now it says (quoting for good measure):
> 1. lets people trade "stocks" that aren't stocks the way people think they are. All (convenient) trades (for its HF clients) get internalized and never ever hit any lit market/exchange. The fact that this is possible is a general issue with the US stock market and lack of meaningful regulation and policing.
Now you're saying "internalized trading". Well this is 100% true - of all brokerages. So this no longer makes RH bad vs anyone else... you like Robinhood now?
There are some more hints though for the whole synthetics conspiracy ongoing. The most recent one, going on right now, being the GameStop stock split through stock dividend failing in Germany, because of DTC/DTCC issues.
These types of splits are not uncommon (Google did one a couple of weeks ago without any issues: https://capital.com/google-stock-split) and I've never heard of a stock split failing due to clearing issues before.
So there's that.
