SpaceX has officially acquired Elon Musk’s artificial intelligence startup xAI, forming what is now the world’s most valuable private company valued at around $1.25 trillion. The merger unites Musk’s rocket and satellite operations with cutting-edge AI development, primarily to advance ambitious plans for building data centers in space.
The combined entity aims to deploy massive constellations of solar-powered satellites equipped with high-bandwidth optical links and unprecedented computing power to run advanced AI models.
SpaceX recently filed with the U.S. Federal Communications Commission for permission to launch up to one million such satellites, operating between 500 km and 2,000 km altitudes. These orbital facilities promise lower costs for AI training and processing by tapping unlimited solar energy, bypassing terrestrial power and land constraints.
This integration builds on synergies across Musk’s ecosystem, including SpaceX’s Starlink for space-based internet and xAI’s expertise in large language models like Grok.
It positions the company for an upcoming initial public offering while addressing xAI’s high operational burn rate of about $1 billion monthly.
Key Company Statements
“SpaceX has acquired xAI to form the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device 
communications and the world’s foremost real-time information and free speech platform,” Elon Musk stated in the announcement.
SpaceX emphasized in its FCC filing that space-based AI compute will soon offer the lowest costs, enabling breakthroughs in machine learning, autonomous systems, and predictive analytics to benefit humanity.
Musk added in a memo: “In the long run, AI in space is evidently the sole method to achieve scalability,” highlighting solar power advantages and the need to shift resource-intensive projects off Earth.
