Just two hours after Robinhood's announcement, shares of GameStop quickly moved into the negative territory, falling 50 percent from Wednesday's closing price.

In response, Ocasio-Cortez threatened to hold a congressional hearing over the trading app's actions However, Robinhood was quick to take drastic steps on Thursday, barring users from being able to freely trade their GameStop stock and only allowing them to close out their positions.

The idea to stick it to Wall Street emerged out of a Reddit chat room, where rookies planned to invest in names like GameStop and AMC Entertainment that are heavily shorted by hedge funds.

The $3 billion deposit requirement was ten times what it had typically been, Tenev said. Tenev said Robinhood’s operations team received a request early Thursday morning from the National Securities Clearing Corporation (NSCC), a subsidiary under the Depository Trust and Clearing Corporation (DTCC), for a security deposit of $3 billion to back up a surge in trade volume related to GameStop and other stocks.
