On Wednesday, Robinhood account holders filed their consolidated second amended complaint alleging that Robinhood Financial LLC, Robinhood Securities LLC, and Robinhood Markets Inc. committed negligence, breach of contract, breach of fiduciary duty, and violations of California's Unfair Competition Law after system failures halted trading last year. The plaintiffs allege that e-trading platform's several dozen outages locked users out of their accounts while the market made big gains, resulting in significant trader losses. The Northern District of California complaint explains how the supposedly everyday-consumer friendly platform works and that its systems crashed due to lack of oversight procedures. According to the complaint, Robinhood takes responsibility for the outages.
