First: RH was not the only brokerage to restrict buying in $GME et al. Much of the below applies to many brokerages. I'm going to use "RH" in my writing for simplicity and because it's the most prominent, but it's not fair to call this a RobinHood issue, per se.

Let's talk plumbing. 🪠🪠
Most RH clients (& all HFs) use “margin” accounts, not “cash” accounts. RH's sign up process nudges new customers into margin accounts by default.
Whether RH should do that is worthy of discussion another day.
This is a story of lending and capital.

When an RH’er buys $GME, a whole bunch of things happen behind the scenes, all of which are the ugly plumbing of Wall Street. pic.twitter.com/qjVGaYeDEU

Side Note for Later:
For equity options contracts (puts and calls), the primary clearing entity is OCC (Options Clearing Corp). I'm going to refer to "DTCC" below, but know that the same story can be told for options with OTC.

This guarantee is typically an extremely low risk proposition.
However, "low risk" does not equal “no risk” pic.twitter.com/uOYBlfuetG

So, you bought $GME in your RH margin account: what's happens behind the scenes?

3) Selling Broker vs. Selling Client: Selling Broker fronts its client credit for the proceeds immediately upon transaction;
4) DTCC vs. Selling Broker: DTCC owes the selling broker proceeds at day's end;
5) RH vs. RH Client: (see next Tweet)— Compound248 💰 (@compound248) January 29, 2021
It's actually not particularly important to the story, but we all know RH’s real customer is not you – you are the product.
RH’s *real* customers are buyers of “order flow”, the largest of whom is Citadel (the same Citadel that bailed out Melvin Capital with Point72 on Monday)
— Compound248 💰 (@compound248) January 29, 2021
Citadel et al get a sneak peak at RH's order flow (ie, pending trade activity) & use that to “provide you liquidity” (ie, front-run your trade).

This is important because if RH failed, you would not “own” your stocks, per se. You would be a creditor with a claim against RH. This is a key risk of margin accounts.
See Lehman Brothers.

While many brokers share the proceeds of stock lending w/ clients, RobinHood does not. RobinHood keeps it all.
This is a critical way RH gets paid. This payment can be VERY large on hard to borrow names.

In order to meet legal requirements, the broker has to find un-lent shares (so the same shares aren’t lent twice). The PB will “tag” those shares, indicate to the client the prevailing cost to borrow, and provide the client a “locate ID” that guarantees that client those shares.

Let's look at the HF’s transaction:
– The PB lent the HF specific $GME shares, which the HF immediately sold, receiving cash.
– The HF balance sheet is: owes shares and has cash…
