Overview
- Musk, who finished three days on the stand Thursday, is suing OpenAI, Sam Altman, Greg Brockman, and Microsoft over what he calls a betrayal of the nonprofit mission.
- Cross-examination focused on emails and texts showing he discussed a for-profit structure and received word of a Microsoft investment, while he said he was misled and admitted he "didn't read the fine print."
- Judge Yvonne Gonzalez Rogers kept the trial focused on alleged breach of charitable trust and barred testimony about AI extinction risk, and the jury serves only in an advisory role in this liability phase.
- Microsoft’s lawyer pointed to a 2020 tweet where Musk said OpenAI was "captured by Microsoft" to argue the claim against Microsoft is too late under a three-year limit.
- OpenAI’s Brockman and then Altman are expected to testify next, and a ruling on liability and possible remedies such as leadership changes, nonprofit reversion, or disgorgement is expected by mid to late May.
