Key Facts OpenAI's bankers have been preparing initial paperwork that could land with the Securities and Exchange Commission within days, people familiar with the matter told the Journal, though plans remain fluid. Goldman Sachs and Morgan Stanley are among the firms advising the company on the draft prospectus, with September floated as a potential debut window, according to the Journal. The filing would come just days after a federal jury in Oakland, California, on Monday threw out Musk's lawsuit against Altman, OpenAI cofounder Greg Brockman and the company itself, which Musk said he plans to appeal. SpaceX, Musk's rocket and satellite company, is expected to unveil IPO paperwork Wednesday ahead of a potential June offering. This is a developing story and will be updated.
