Elon Musk has filed a preliminary injunction against OpenAI and Microsoft in California’s Northern District Court to prevent OpenAI’s transition to a for-profit entity. According to tech journalist Kyle Wiggers reporting for TechCrunch, the filing accuses OpenAI’s leadership, including CEO Sam Altman and Microsoft, of anticompetitive behavior and self-dealing. The motion claims the defendants are discouraging investors from backing rivals like Musk’s xAI, sharing proprietary information illegally, and potentially harming marketplace competition. Musk’s attorneys argue that immediate court intervention is necessary to prevent “irreparable harm” and maintain OpenAI’s original nonprofit mission. The filing also seeks to halt any transfer of intellectual property and assets during the transition. OpenAI has dismissed the claims as “utterly without merit” in their response.
