On February 2, 2026, SpaceX acquired xAI in a $1.25 trillion deal—the largest corporate merger in history. SpaceX is valued at $1 trillion, xAI at $250 billion. Musk plans to build orbital data centers using 1 million satellites, claiming "space-based AI is the only way to scale." An IPO targeting $50 billion is expected in June 2026.
The Largest Merger in History
On February 2, 2026, Elon Musk announced that SpaceX would acquire his AI startup xAI in a deal valued at $1.25 trillion. The all-stock transaction makes it the largest corporate merger ever recorded, surpassing any previous tech or industrial combination.
According to documents viewed by CNBC, the deal values SpaceX at $1 trillion and xAI at $250 billion. The merger is structured as a "triangular merger," keeping xAI as a fully owned subsidiary while insulating SpaceX from potential legal exposure.
Data Centers in Space
The strategic rationale for the merger is ambitious: building AI data centers in orbit. On January 30, 2026, SpaceX filed with the FCC to launch a constellation of up to 1 million satellites operating at altitudes between 500 and 2,000 kilometers.
"Global electricity demand for AI simply cannot be met with terrestrial solutions, even in the near term, without imposing hardship on communities and the environment," Musk wrote. "In the long term, space-based AI is obviously the only way to scale."

The Numbers Behind the Deal
The financial picture reveals why the merger was necessary. According to Bloomberg, xAI is burning approximately $1 billion per month as it races to compete with OpenAI and Anthropic. Meanwhile, SpaceX generated an estimated $8 billion profit on $15-16 billion revenue in 2025.
The deal structure was designed to protect SpaceX's upcoming IPO. The tax-free reorganization allows xAI shareholders to defer capital gains taxes until they sell their SpaceX shares. Share conversion: 1 xAI share = 0.1433 SpaceX shares.
June 2026 IPO
SpaceX is planning an IPO for June 2026, reportedly timed to coincide with Musk's birthday and a planetary alignment. The Financial Times reports the company is looking to raise up to $50 billion at a valuation as high as $1.5 trillion.
The merger dramatically reshapes the IPO, giving investors access to both a dominant space company and a frontier AI model developer in a single offering. However, some analysts question whether the June timeline is still viable given the complexity of integrating two companies.
Concerns and Skepticism
Not everyone is convinced. Harvard astrophysicist Jonathan McDowell notes there are currently only 14,518 active satellites in Earth orbit—9,555 of them Starlink. A million-satellite constellation raises serious concerns about Kessler Syndrome, where orbital collisions create cascading debris.
"I think it's unclear at this stage whether it's feasible or not—but SpaceX seem to think it is," McDowell told The Register. Many scientists consider a million additional satellites a "nightmare scenario" for space sustainability.
