Elon Musk faced nearly three hours of intense cross-examination by OpenAI's attorney on Wednesday, marking the second day of his testimony in a high-stakes civil trial against the company. As he prepares for further questioning on Thursday, several key revelations emerged regarding his motivations for the lawsuit, his communications with colleagues, and the early governance of the organization. The trial has scrutinized Musk's decision to sue only in 2024, despite leaving OpenAI in 2018. During testimony, Musk explained that he initially supported the creation of a for-profit subsidiary to fund the nonprofit, provided the profit arm served the mission. However, he stated his stance shifted dramatically after Microsoft announced a $10 billion investment in the fall of 2022. Musk argued that such a massive sum indicated a commercial return was expected, effectively making the for-profit entity control the nonprofit. He recalled describing the situation to co-founder Sam Altman as a bait and switch. A significant portion of the examination focused on Musk's text communications with Shivon Zilis, his partner and the mother of his children. Zilis's meeting notes, entered into evidence, suggest that in August 2017, Musk directed her to form a C-corporation structure and recruit staff to move to Tesla. When presented with these records, Musk disputed his recollection of the specific instruction but admitted he wanted to maintain open lines of communication with OpenAI and ensure a flow of information. He testified that his intent was to monitor developments at the company while he was occupied with other ventures. Exhibits also clarified Musk's role in OpenAI's early leadership structure. While he viewed his responsibilities as similar to a CEO, he declined the formal title of co-CEO in a 2015 email to Altman. Musk cited concerns that the title would create public perception issues for SpaceX and Tesla, where he was already heavily committed. This caution proved prescient, as Musk testified that Tesla faced severe financial difficulties and was on the verge of bankruptcy between 2017 and 2018, a period he described as so demanding that he slept on the factory floor. Finally, the trial shed light on the compensation strategies discussed among the founders. Although OpenAI began as a nonprofit, Musk and Altman planned to offer competitive salaries, bonuses, and stock options. Emails revealed Musk's willingness to allow employees to convert cash compensation into SpaceX or Y Combinator stock. Additionally, he offered a limited number of employees free Model 3 Teslas. When questioned about receiving these vehicles, Musk clarified that he personally paid full price for any cars he acquired, denying any conflict regarding discounts. The proceedings continue as the court examines the shifting dynamics between the co-founders and the company's evolution.
