SpaceX’s long-awaited IPO is getting closer, with a stock market debut likely as early as June.
As part of that process, Musk’s company on May 20 filed with the SEC a document that provides some insights into its finances.
While much of the media attention is focused on what is expected to be the largest IPO ever, which could make Musk the world’s first trillionaire, arguably the most interesting details contained in the filing relate to xAI, the AI lab that was merged with SpaceX earlier this year, having itself acquired X (formerly Twitter) in 2025 as part of its plan to accelerate its Grok chatbot.
