Mega IPOs on the way: SpaceX releases filing as OpenAI reportedly prepares for September listing
SpaceX Corp. today published the filing for its upcoming initial public offering.
The move came against the backdrop of reports that OpenAI Group PBC could submit the paperwork for its own IPO to regulators as early as Friday. According to the Wall Street Journal, the company may go public in September. But the paper’s sources cautioned that the time frame could still change.
The IPO updates from SpaceX and OpenAI come a day after a jury dismissed a high-profile lawsuit that Elon Musk had brought against the latter company. The litigation could have potentially complicated the ChatGPT developer’s efforts to go public. Anthropic PBC, OpenAI’s top rival in the AI market, is expected to file for an IPO of its own later this year.
SpaceX, which competes with OpenAI through its xAI unit, generated sales of $4.69 billion in the first quarter. That represents a 15% year-over-year increase, less than half the 33% sales gain it delivered in 2025. In the same time frame, SpaceX’s expenditures have increased significantly. It logged a net loss of $4.28 billion in the first quarter compared to $4.94 billion during all of 2025.
