Closing arguments concluded May 15 in the Northern District of California, sending to the jury a case that will determine whether OpenAI may complete its conversion from a nonprofit to a for-profit entity [1]. The case, *Musk v. Altman*, centers on Elon Musk's claim that OpenAI's leadership betrayed the charitable mission under which the organization was founded and raised early funding [1]. After more than ten days of testimony, jurors in Oakland now hold the question of whether that conversion constitutes a breach of charitable-trust obligations [2].
The trial featured testimony from OpenAI CEO Sam Altman, who took the stand May 12 and denied ever promising Musk that OpenAI would remain a nonprofit in perpetuity [1]. Altman testified that Musk had sought controlling equity in OpenAI and had separately proposed merging the organization with Tesla, characterizations Musk's counsel disputed by drawing on statements from former colleagues to attack Altman's credibility [1]. Microsoft CEO Satya Nadella also testified, disclosing that Microsoft had developed internal concerns about its degree of dependence on OpenAI as a technology partner [3]. Nadella's appearance underscored the commercial stakes for entities beyond the immediate parties [3].
The substantive significance of the verdict extends well beyond the two principals. A ruling for Musk could block or condition OpenAI's restructuring and establish that founders and early donors retain enforceable claims against a nonprofit's deviation from its founding mission [2]. A ruling for the defendants would effectively clear the path for OpenAI's for-profit conversion and signal that courts will apply a deferential standard to mission-change decisions made by nonprofit boards [1]. Either outcome will carry persuasive weight as other AI organizations weigh analogous structural shifts, given the absence of established precedent on charitable-trust duties in the technology sector [2].
No verdict timeline has been set. Once the jury returns a decision, post-trial motions and a potential appeal are likely regardless of the outcome, given the magnitude of the financial interests at stake and the unsettled state of the governing legal doctrine [2].
