Judge Sends Musk’s OpenAI Case to April Jury Trial With Microsoft Still a Defendant

Jurors will weigh 2017 internal messages alongside Microsoft’s knowledge.

Overview

  • U.S. District Judge Yvonne Gonzalez Rogers rejected OpenAI and Microsoft motions to dismiss, clearing the case for trial starting April 27, 2026, in Oakland.
  • The court said Musk has standing tied to his roughly $38 million contribution and may argue OpenAI broke nonprofit and open‑source commitments.
  • Evidence heading to the jury includes 2017 messages, such as Greg Brockman’s note stating he could not say the group was committed to a nonprofit structure.
  • Claims that Microsoft knowingly aided any breach will be tried, while an unjust‑enrichment count against the company was dismissed.
  • OpenAI told investors the suit is baseless and likely limited to the $38 million at issue, as prediction market Kalshi priced a roughly 57% chance of a Musk win and Jim Cramer warned of IPO risks.
