Updated Mon, Apr 6 2026 5:08 PM EDT Meta, Google under fire as court cases bypass 30-year-old legal shield OpenAI said in that letter that Musk will likely make comments about the AI company that are not "grounded in reality" and are "typical of the harassment tactics he's previously deployed." In the letter on Monday, OpenAI referenced a recent report from The New Yorker. That report said Musk and his "intermediaries" had conducted extensive opposition research on Altman, tracking his flights and other movement, and that they and other company rivals circulated this research, as well as false allegations of sexual misconduct, by the OpenAI CEO. Musk and the executive who runs his family office, Jared Birchall, did not immediately respond to a request for comment. OpenAI Chief Global Affairs Officer Chris Lehane told CNBC on Monday that Musk and Zuckerberg are "turning to conduct and approaches that we do think are really highly questionable and sharply worthy of investigation." He asked why "two of the top four wealthiest people, most powerful people in the world," are trying to stop a non-profit from moving forward. OpenAI also referenced SpaceX's IPO in the letter, days after Musk's rocket company confidentially filed for what's likely to be a record offering. The letter said that if Musk's legal efforts are successful, it will benefit xAI's Grok AI platform, which is being investigated globally "for generating sexually explicit deepfakes of women, including children, without their knowledge or consent, allegedly to boost usage of its services ahead of an upcoming IPO." For years, Musk has accused both Delaware and California of bias against him or his companies, moving Tesla and SpaceX headquarters from California to Texas, and reincorporating his businesses, former Delaware corporations, in Nevada and Texas. XAI is also suing California Attorney General Rob Bonta, alleging that the state's new AI data transparency law violates the company's rights to free speech and to protect trade secrets. — CNBC's Lora Kolodny contributed to this report.
