xAI now officially operates as SpaceXAI. The rebrand was announced, appropriately enough, on X. SpaceXAI has now consolidated Musk’s major non-Tesla ventures under one corporate entity, including SpaceX, xAI and the recently acquired Cursor.
The move formalizes what Musk announced back in May, when he said xAI would no longer exist as a separate company under SpaceX. As mentioned in our earlier reporting, the merger was aimed at (eventually) building data centers in space.

That ambition is getting a bit more realistic as rocket launch costs have decreased, mostly thanks to SpaceX’s innovations in the area of reusability. Even before the merger was announced, SpaceX filed an application with the FCC to launch a million satellites for a space-based data center. When SpaceX acquired xAI in February, Musk argued that “global electricity demand for AI simply cannot be met with terrestrial solutions.”
From merger to monetization
The road for xAI, now SpaceXAI, has been bumpy. The company lost several co-founders shortly after the February deal, which valued the combined entity at 1.25 trillion dollars. Rather than chasing frontier models, the firm now largely rents out compute. Google agreed to pay 920 million dollars per month for GPU capacity from the Colossus data centers in Memphis through 2029.
Not everyone is convinced, and the infrastructure deals hide an alleged demise of the “AI kan” status of Grok maker xAI. Former Meta AI chief Yann LeCun recently called the company a “failure”, noting that Grok has struggled to win enterprise adoption. Earlier this year, SpaceX also acquired coding tool Cursor for 60 billion dollars, although the shape which Musk is angling for remains unclear.
Public listing behind the rebrand
SpaceX, together with xAI and X, went public in June. A limited amount of shares are being floated, and they have driven up the total value of the company to 2.1 trillion dollars. The new brand has not yet appeared in official filingsa, but the website already shows the updated logo and company name. To note, xAI had acquired X in 2025, which is why the social network now sits under SpaceXAI too.
