On July 12–13, 2021, Musk testified in a lawsuit brought by Tesla shareholders. The plaintiffs alleged that he used Tesla's 2016 acquisition of SolarCity to bail out SolarCity while chairing both companies’ boards. Closing arguments in the case took place in January 2022, with lawyers for the plaintiffs arguing Musk should return the Tesla shares he received for his SolarCity stock, valued as of January 2022 at $13 billion. A ruling in the case remained pending as of April 21, 2022.
