Elon Musk took the witness stand on April 29, 2026, in an OpenAI lawsuit, where he contradicted a previous tweet about Tesla's progress on artificial general intelligence. The testimony, covered by TechCrunch, highlighted how Musk's own social media posts became evidence in the courtroom.
The trial, which remains ongoing, has drawn attention to Musk's public statements on artificial intelligence and Tesla's technology roadmap. During the hearing, Musk disputed the characterization of a tweet he had made about AGI, according to the report.
The legal proceeding marks a significant distraction from Musk's typical social media cadence. Musk has taken on an expanded role with the Department of Government Efficiency and continues to lead Tesla, SpaceX, and xAI, leaving less time for posting on X.
Market observers tracking Musk's tweet count for the May 23-25 weekend saw a probability drop of nearly 18 percentage points. The market, which closed on May 25, had priced a low likelihood of Musk posting fewer than 40 tweets over the three-day period.
