Elon Musk just pulled off his biggest corporate shuffle yet. SpaceX has swallowed xAI in an all-stock deal that values the combined beast at roughly $1.25 trillion (£910 billion). Translation? The world’s most valuable private company just got created, and it’s gearing up for what could be the mother of all IPOs later this year.
The move isn’t just about empire-building. It’s Musk betting big on space-based AI infrastructure whilst packaging his rocket business, chatbot tech, and satellite internet under one roof for public investors.
What’s Actually in This Deal?
SpaceX Gets Valued at $1 Trillion, xAI at $250 Billion
The merger, announced Monday on SpaceX’s own website, pegs SpaceX at around $1 trillion and xAI at $250 billion. That’s a massive jump from SpaceX’s December valuation of $800 billion and xAI’s recent $230 billion Series E round last month.
The deal also brings xAI’s Grok chatbot and X (formerly Twitter) into the SpaceX fold. So now Musk’s got rockets, AI, social media, and Starlink satellite internet all playing for the same team.
He’s calling it a “vertically integrated innovation engine.” Fancy talk for: everything I own now talks to everything else I own.
Why Merge Now? The IPO Angle
SpaceX has been teasing a public listing for ages, and this merger is basically the pre-game show. By absorbing xAI, SpaceX can pitch investors a unified AI-meets-space growth story instead of just “we launch rockets really well.”
And that story revolves around one big idea: space-based data centres.
Musk’s argument? Earth can’t handle AI’s power demands. He reckons global electricity needs for artificial intelligence “cannot be met with terrestrial solutions” without wrecking the planet or the grid. His solution: stick the data centres in orbit.
“In the long term, space-based AI is obviously the only way to scale,” the announcement read. Bold claim, but classic Musk.
Musk’s Corporate Jenga Tower Keeps Growing
This isn’t the first time Musk’s shuffled his deck. Last year, xAI bought X in another all-stock deal, giving the AI firm access to heaps of social media data. Then last month, Tesla announced a $2 billion investment into xAI, which raised eyebrows among shareholders worried about conflicts of interest.
Now SpaceX is the mothership, and everything else slots underneath. It’s efficient, sure. But it’s also putting a lot of eggs in one very Elon-shaped basket.
What Could Go Wrong?
Regulators and national security types are going to have questions. SpaceX holds billions in US government defence and intelligence contracts, and Musk’s already juggling leadership roles across multiple companies. Adding AI into that mix? Expect scrutiny.
There’s also the timing. Musk’s had a rough few weeks—Tesla earnings disappointed, and xAI’s governance has been under the microscope. This merger feels like a strategic reset, but it’s also a high-wire act.
The Bottom Line
Musk’s betting that space-based AI is the future, and he’s consolidating his empire to make it happen. The $1.25 trillion valuation sets up what could be the biggest IPO in history, but it also raises big questions about conflicts, oversight, and whether one person should control this much critical infrastructure.
One thing’s certain: if this IPO happens, it’ll be unmissable.

FAQ
Q1: Is SpaceX actually going public this year?
A: SpaceX is preparing for an IPO as early as summer 2025, though no official date has been confirmed. The xAI merger is widely seen as a move to make the company more attractive to public investors by adding AI growth potential.
Q2: Why does Musk think AI data centres need to be in space?
A: Musk argues that Earth’s power grids can’t meet the massive electricity demands of AI infrastructure without major environmental and social costs. Space-based data centres would sidestep those constraints, though the logistics remain highly experimental.
Q3: What happens to X (formerly Twitter) in this deal?
A: X gets folded into SpaceX alongside xAI’s Grok chatbot. This gives SpaceX control over Musk’s social media platform, AI tools, and the data that powers them—all under one corporate structure.
Q4: Will regulators block this merger?
A: It’s possible. SpaceX has major US defence contracts, and Musk’s overlapping roles across companies could raise conflict-of-interest concerns. National security agencies and antitrust regulators are likely to review the deal closely.
Q5: How did xAI’s valuation jump so quickly?
A: xAI raised $20 billion in a Series E funding round last month, valuing it at around $230 billion. The hype around AI, plus access to X’s data and Musk’s track record, helped drive investor interest despite the company’s relative youth.
