SpaceX has acquired xAI, an artificial intelligence firm founded by Elon Musk three years ago, in a deal that combines the two privately held firms into a company with a US $1.25 trillion reported valuation. The combined company is planning am Initial Public Offering (IPO) this year.

Speaking of the deal, Elon Musk said in a post in Spacex' website that the combined companies will “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.”
Musk added that "in the history of spaceflight, there has never been a vehicle capable of launching the megatons of mass that space-based data centers or permanent bases on the Moon and cities on Mars require. Even in 2025, the most prolific year in history in terms of the number of orbital launches, only about 3000 tons of payload was launched into orbit, primarily consisting of Starlink satellites carried by our Falcon rocket.
The requirement to launch thousands of satellites to orbit became a forcing function for the Falcon program, driving recursive improvements to reach the unprecedented flight rates necessary to make space-based internet a reality. This year, Starship will begin delivering the much more powerful V3 Starlink satellites to orbit, with each launch adding more than 20 times the capacity to the constellation as the current Falcon launches of the V2 Starlink satellites. Starship will also launch the next generation of direct-to-mobile satellites, which will deliver full cellular coverage everywhere on Earth.
While the need to launch these satellites will act as a similar forcing function to drive Starship improvements and launch rates, the sheer number of satellites that will be needed for space-based data centers will push Starship to even greater heights. With launches every hour carrying 200 tons per flight, Starship will deliver millions of tons to orbit and beyond per year, enabling an exciting future where humanity is out exploring amongst the stars.
The basic math is that launching a million tons per year of satellites generating 100 kW of compute power per ton would add 100 gigawatts of AI compute capacity annually, with no ongoing operational or maintenance needs. Ultimately, there is a path to launching 1 TW/year from Earth.My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute will be in space. This cost-efficiency alone will enable innovative companies to forge ahead in training their AI models and processing data at unprecedented speeds and scales, accelerating breakthroughs in our understanding of physics and invention of technologies to benefit humanity.
This new constellation will build upon the well-established space sustainability design and operational strategies, including end-of-life disposal, that have proven successful for SpaceX’s existing broadband satellite systems. The capabilities we unlock by making space-based data centers a reality will fund and enable self-growing bases on the Moon, an entire civilization on Mars and ultimately expansion to the Universe," Musk concluded.
