Per a federal court ruling on August 11, 2022, Robinhood Markets Inc, the app-based online stock trading platform, must face market manipulation claims brought by a class of its investors. 
The ruling by Judge Cecilia Altonaga of the U.S. District Court for the Southern District of Florida denied Robinhood’s motion to dismiss shareholder allegations of market manipulation. The allegations stem from Robinhood’s actions in the wake of the meme stock frenzy of early 2021.  In the lawsuit, Robinhood shareholders allege that Robinhood engaged in tactics aimed at artificially lowering the prices of nine stocks at the center of the frenzy. These stocks included GameStop, Bed Bath & Beyond, and AMC. 
The meme stock frenzy took place in January 2021 when social media users stirred extraordinary investment interest in several unexpected stocks. The outpour of interest in these stocks was not founded on each stock’s actual performance, but rather on the prospect of triggering a short squeeze on the stocks.
