xAI Merged into SpaceX as SpaceXAI Division, Valued at $250B in All-Stock Deal
On May 6, 2026, Elon Musk formally dissolved xAI as an independent company and folded it into SpaceX as a new division called SpaceXAI. The all-stock transaction valued SpaceX at $1 trillion and xAI at $250 billion, creating a combined entity worth $1.25 trillion. The move brings Grok, the X social media platform, the Grok Build coding tool, and the Colossus supercomputer under SpaceX's corporate structure. Michael Nicolls was appointed president of the division. The merger represents the culmination of a consolidation that began in March 2025, when xAI acquired X Corp. in an all-stock deal valuing X at $33 billion. The restructuring followed layoffs of 500 data annotation workers in September 2025 and additional cuts in February 2026 as the company shifted from data labeling to automated AI training pipelines. SpaceXAI now controls nearly 2 gigawatts of compute power, with plans to expand the Colossus supercomputer to house at least 1 million GPUs. The division also inherited xAI's $200 million US Department of Defense contract for military AI applications. The SpaceX IPO filing, reported to be in progress, would make SpaceXAI the only publicly traded company combining space exploration, social media, and frontier AI capabilities.
Merging AI and social media into SpaceX is unprecedented—it creates a vertically integrated empire spanning rockets, chatbots, and a global communication platform. The SpaceX IPO filing will be the most watched tech listing in history, and the $250B xAI valuation shows how quickly AI assets have scaled.
What does the xAI-SpaceX merger mean for Grok users?
Grok continues operating as before but now under the SpaceXAI division. The merger brings more compute resources from SpaceX's infrastructure, potentially enabling faster model training and deployment. The SpaceX IPO could eventually give Grok public market backing.
