The U.S. Supreme Court is set to hear arguments on November 6 from Facebook and Nvidia in separate securities fraud lawsuits that could have significant implications for how companies disclose financial risks. Facebook's case, brought by Amalgamated Bank, centers on allegations that it misled investors about the 2015 Cambridge Analytica data breach. Nvidia is accused of downplaying the high demand for its GPUs tied to volatile cryptocurrency markets. Both companies appealed after the 9th Circuit allowed the lawsuits to proceed. The outcomes of these cases could make it harder for private litigants to hold companies accountable for securities fraud.
