Elon Musk’s SpaceX launched its official rebranding on Monday following its merger with xAI, the parent company of social media platform X, forming a new entity called SpaceXAI. SpaceXAI, which recently launched its initial public offering, integrated xAI in February as Musk sought to consolidate several of his businesses. The X app merged with xAI in March 2025. According to Nikita Bier, X’s head of product, X is now “X App (Formerly Twitter), Acquired by xAI, a Product by SpaceXAI, a division of SpaceX.” X drives the data intake for xAI, and xAI provides artificial intelligence tools to SpaceX. X and xAI originally merged because X was running out of money due to its ad intake drying up, and xAI also ran into money problems as its ambitious AI project reportedly burned through billions of dollars to compete with OpenAI. X merged with xAI, which then merged with SpaceX, which is now flush with a new pool of capital from its IPO.
