Confirming earlier reports, late on Monday Elon Musk said SpaceX has acquired xAI, a deal that combines his powerful rocket-and-satellite business with his artificial-intelligence startup that is facing steep competition. SpaceX confirmed the deal Monday, posting a memo Musk sent out about the arrangement on its website.
The deal gives SpaceX a valuation of $1 trillion, and xAI a value of $250 billion, Bloomberg added citing sources. The combined company’s valuation of $1.25 trillion was announced to employees in a memo on Monday.
“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,
The deal brings together two of the largest closely held companies in the world. XAI raised funds at a $230 billion valuation in January, while SpaceX was set to go ahead with a share sale in December at a valuation of about $800 billion. Additionally, the combination will bring together a mature and dominant company in SpaceX, with one that is in a nascent stage. Musk’s xAI is also facing formidable competition from OpenAI, Anthropic and others to build large language models and big businesses around AI technology.
Terms of the offering including price and valuation weren’t disclosed in the statement on SpaceX’s website.
The company is still expecting to hold an initial public offering later this year, one of the people said. SpaceX had been planning an IPO that could raise as much as $50 billion, Bloomberg News reported earlier.
In his memo, Musk also said global electricity demand for AI can’t be met with data centers on the ground, and that space-based technology will be the only way to scale up AI over the long term (something we discussed in December, sharing several stock picks which have since more than doubled).
He pitched using solar power from space as a transformative option to ramp up computing resources needed for AI. The executive has been frequently discussing orbital data centers at events and on X.
Polymarket odds of a deal being formalized by June 30 initially came out around 20% on Jan 30 when the first reports of a combination emerged. They then spiked earlier today after the Bloomberg report, and are now trading at 100%.

On Friday, SpaceX said in a regulatory filing that it wants to deploy an orbital AI network with up to one million satellites over time. The company will need to secure regulatory permission to deploy that fleet. Even if it gets it, which will be problematic to say the least under any Democratic regime, it is unclear just how SpaceX will provide physical service for the airborne data centers.
It will also need to demonstrate further progress with Starship, a powerful two-stage rocket the company has been testing in flight since 2023. Starship hasn’t yet deployed an operational payload during the test missions, and SpaceX has grappled with setbacks during the development campaign.
Last week, The Wall Street Journal reported SpaceX and xAI were planning the tie-up, and other news organizations reported on discussions about the deal.
The deal further entangles Musk’s various business ventures. The billionaire acquired Twitter in late 2022, renamed it X, then merged the site with his artificial intelligence startup xAI in a $33 billion deal. XAI, which also operates chatbot Grok, is an expensive operation, burning around $1 billion a month in service of its stated ambition to gain “a deeper understanding of our universe.” A merger with SpaceX will pool capital and talent, while providing access to computing power.
SpaceX stands out as arguably Elon’s most successful and consistent business. The company, the only American one that can routinely send astronauts to and from the International Space Station, is a key rocket launch provider for both NASA and the US Department of Defense, which the White House has moved to rename the Department of War. The increasing revenue it’s generating from the Starlink network of more than 9,000 satellites is even more significant, now outpacing launch sales and presenting a potential source of funding for xAI’s capital-intensive business.
