Musk-Altman trial reveals Altman's $1.5bn Helion stake, judge's tight schedule, trustworthiness clash

The case unfolded in a federal court in California over three weeks, with Elon Musk alleging that Altman misled him about OpenAI’s nonprofit commitments. Testimony came from prominent tech figures, including OpenAI co‑founder Ilya Sutskever, former board member Tasha McCauley, and Microsoft CEO Satya Nadella, who noted his firm’s extensive due diligence before investing billions in OpenAI. Microsoft appears as a co‑defendant, accused by Musk of aiding and abetting the alleged scheme. The trial also touched on Musk’s claim that Altman “stole a charity,” a sum Musk himself describes as tiny relative to his wealth.

Court records show Altman holds a stake in Helion Energy valued at more than $1.5 billion; he served as chairman of Helion’s board until recently and the startup has yet to deliver any power. A power‑purchase agreement between OpenAI and Helion was flagged as potentially worrisome given the lack of delivered energy. Judge Gonzalez Rogers maintained a strict schedule, allowing only two 20‑minute breaks each day and denying a lunch break to keep participants alert; she also admonished those who took photographs or asked off‑limits questions, and once deadpanned about federal funding when audio problems arose. During cross‑examination, Musk’s lawyer Steven Molo asked Altman if he is completely trustworthy; Altman answered, “I believe so,” and later sought to amend his reply to “yes.” The exchange highlighted broader scrutiny of Altman’s candor, fueled by a recent New Yorker profile and testimony from former OpenAI board members and executives who described instances where they felt he was not fully forthcoming.

The size of Altman’s Helion stake raises questions about possible conflicts of interest, especially given his prior board role and the ongoing power‑purchase talks between OpenAI and the fusion company. The judge’s tight timetable reflects a courtroom prioritizing efficiency, limiting downtime for lawyers, jurors, and observers. Altman’s brief trustworthiness answer became a focal point for assessing his credibility as the jury deliberates. Observers should watch for the jury’s verdict, any subsequent appeals, and how the outcome might influence OpenAI’s governance, Altman’s future investments, and the broader conversation about transparency in high‑stakes tech ventures.
