US judge dismisses xAI trade secret lawsuit against OpenAI

ai-technology · 2026-06-15

On Monday, a federal judge in San Francisco ruled against Elon Musk's xAI, dismissing its lawsuit aimed at OpenAI. The court found that xAI did not demonstrate that OpenAI had persuaded former employee Xuechen Li to misappropriate trade secrets related to chatbots. This ruling follows the earlier dismissal of a similar lawsuit in February. The initial complaint, submitted in September, claimed that xAI staff who transitioned to OpenAI had unlawfully taken confidential materials, including source code. Additionally, this dismissal comes after a federal jury verdict on May 18, which was unfavorable to Musk in a separate US$150 billion case alleging that OpenAI and Sam Altman had violated the company's charitable objectives.
