OpenAI Files for IPO After Winning Musk Court Battle

OpenAI is preparing to file a confidential draft of its IPO prospectus as early as Friday, March 13, 2026, as the company moves toward what could be one of the largest public market debuts in history, according to sources cited by CNBC. The filing comes just a day after OpenAI secured a major legal victory when Elon Musk lost his lawsuit that had threatened the AI company's corporate structure, leadership, and finances. The ChatGPT maker has been working with Goldman Sachs and Morgan Stanley, two of the most prominent tech IPO bankers, and CEO Sam Altman reportedly hopes the company will be ready to go public by September, sources told the Wall Street Journal. OpenAI may file IPO paperwork confidentially with regulators within days or weeks. The timing of OpenAI's IPO push coincides with expectations that SpaceX, now one of OpenAI's chief competitors after absorbing Musk's AI venture xAI, will release its own IPO filings as soon as this week. The two companies represent the most high-profile IPO candidates of the era, setting the stage for what many are calling the next battle between Musk and Altman, though this time playing out on financial markets rather than in courtrooms.
