SpaceX is acquiring xAI, Elon Musk’s artificial intelligence company, in an all-stock deal that values the combined business at $1.25 trillion. The deal, announced on 2 February, values SpaceX at $1 trillion and xAI at $250 billion, according to a Reuters factbox, and CNBC called it “the biggest merger of all time”.
The deal in plain terms
No cash changes hands. xAI shareholders receive SpaceX stock, and xAI becomes a wholly owned subsidiary of SpaceX. The two headline valuations add up neatly: $1 trillion for the rocket and satellite company, $250 billion for the AI lab, $1.25 trillion together.
The xAI number is worth a second look. Reuters notes that xAI was valued at $230 billion in November. So the price SpaceX is putting on it in stock is higher than that last valuation, but not dramatically so. For a company growing as fast as the AI labs claim to be, that is a fairly restrained step up.
Two very different balance sheets
The Reuters factbox is most useful where it puts the two companies’ finances side by side, and they could hardly look more different.
SpaceX is a profitable business. Reuters puts its annual revenue at $15 to 16 billion, with profit of about $8 billion.
xAI, in a recent quarter, posted a net loss of $1.46 billion on revenue of $107 million. In other words, its losses dwarfed its sales many times over.
That contrast explains the structure better than any press release could. Training and serving large AI models is expensive, and a loss of that size points to heavy spending. SpaceX has a large, cash-generating business. Folding the loss-making AI lab into the profitable launch company puts xAI’s costs next to SpaceX’s earnings inside one group.
What caught my attention is how the all-stock structure shifts the risk. SpaceX shareholders now own a slice of xAI’s losses as well as its upside. If xAI’s bet on AI pays off, they share in it. If the spending continues without matching revenue, it is SpaceX’s profit that absorbs it.

Why it matters
The headline size will get most of the attention, but the more lasting story is concentration. Musk’s AI work and his space business now sit under one corporate roof. For customers, partners and regulators, that means one counterparty instead of two, with SpaceX’s balance sheet standing behind xAI’s commitments.
There is also a direct link to our region. In November, xAI was named the first customer for a planned flagship data centre in Saudi Arabia, built by HUMAIN with NVIDIA hardware. That project was announced when xAI was an independent company. From now on, the customer on the other side of that relationship is a SpaceX subsidiary. The deal coverage I have read says nothing about the Saudi plans, but Gulf partners are now dealing, indirectly, with a much larger and more diversified group.
For investors and the wider AI industry, the deal is also a data point on how AI losses get financed. Many AI labs raise money round after round from outside investors. xAI has taken a different route and attached itself to a profitable sister company. I expect others to watch closely whether that model works.
What to watch
- Details of how xAI will be run as a SpaceX subsidiary, and who leads it.
- Whether xAI’s quarterly losses narrow as revenue grows, now that its numbers sit inside SpaceX’s.
- Any regulatory review of the combination.
- Whether xAI’s existing commitments, including the planned Saudi data centre, are restated under the SpaceX name.
