Cory Doctorow has an excellent #Gamestop / #Robinhood / #CitadelCapital explainer:

… But there’s a third story, and I think it’s the most important one. That’s Alexis Goldstein’s account of what’s going on with Robinhood and the institutional investors it’s in bed with.

Recall that all of this is only possible because Robinhood lets average joes buy and sell stocks for free. How can Robinhood give away a service that costs it money and still stay in business? (Hint: They’re not making it up in volume).

The answer is: surveillance. Robinhood partners with institutional investors and lets them spy on what the average joes are buying and selling. Sometimes, this is just “market intelligence” (“Hey, people like fidget spinners”) but the main event is front-running.

If you’re paying Robinhood to tell you what assets its customers are about to buy, you can go out and buy them up first and sell them for a profit to Robinhood’s customers.

Or you can buy some of that asset up because you know its price will go up once Robinhood’s customers orders are filled.

Or both.

Citadel Securities is Robinhood’s main institutional investor partner. Founded by billionaire Ken Griffin, they combine tech (high-frequency trading), an “asset manager” (they spend other peoples’ money) and a “market maker” (they sell things like options).

Citadel gets to see all those r/wallstreetbets buy orders before they’re filled. They can fill some of those orders, making a profit. They can buy some of the same stock for themselves, making a profit. They can sell options, making a profit.

A little bit of this profit comes at the expense of average joes: if there wasn’t a front-runner marking up the stocks they buy, the average joes would pay a little less. But the average joes are still profiting from the destruction of the shorts.

Citadel is merely taxing their winnings. The real losers here, though are Citadel’s competitors, funds like Melvin Capital, who were seriously short on Gamestop and went bust thanks to all of this. Guess who bought Melvin at fire-sale prices? That’s right, Citadel.

So the third story goes like this: there are a lot of average joes. They’re numerous, pissed and smart. They move a lot of money against shorts and make it go farther thanks to the force-multiplier effect of options.

Then all this activity is multiplied again by Citadel, a fund that is no better (and no worse) than Melvin or the other targets of the average joes’ wrath. Citadel’s bots are triggered by the average joes’ activity, which turns kilotons of damage into gigatons. …
