SpaceX has officially let go of the xAI name. The AI company is now called SpaceXAI, bringing a branding decision that Elon Musk first spoke about in May into effect and giving his AI products the same identity as his space company.
The rebrand follows SpaceX鈥檚 acquisition of xAI and X in February, bringing Grok, the social media platform and the company鈥檚 AI work inside the same business. This week, the company also updated its account on X, replacing the xAI name and logo with SpaceXAI.
The announcement itself was short with the newly renamed account posting, 鈥淲e are now @SpaceXAI,鈥� with a 10 second video showing the old xAI logo folding into the new SpaceXAI logo.

Why Retire The xAI Name?
听
The new name brings Musk鈥檚 AI work much closer to the SpaceX brand that already has global recognition.
Business Insider reported that Musk said in May that xAI would be dissolved as a separate company and folded into SpaceX, with its AI products carrying the SpaceXAI brand instead. That means Grok now becomes a product inside the SpaceX family, rather than belonging to a separate business.
The rebrand comes not long after SpaceX鈥檚 record breaking public listing in June. According to Business Insider, the company raised $75 billion in what it called the largest public offering ever, giving SpaceX a valuation of about $1.77 trillion.
That makes the rebrand a lot bigger than just a logo update. It gives investors, developers and customers one name for products that had already been operating under the same corporate roof.

How Important Is AI To SpaceX?
听
SpaceX has become famous for rockets and satellites, although its financial filings say something else鈥�
According to Business Insider, the company spent $12.7 billion on AI capital expenditure during 2025. That was over three times the amount spent on its space and connectivity businesses, which include Starlink.
Business Insider also reported that the AI division has been operating at a net loss. Even so, SpaceX said AI has the largest total addressable market 鈥渋n human history.鈥�

Those filings also set out one of the company鈥檚 most unusual ambitions. SpaceX said it plans to place AI compute satellites, effectively data centres in space, as early as 2028.
Large customers are already lining up for computing capacity. Business Insider reported that Anthropic agreed to pay SpaceX $1.25 billion each month for access to compute power at its Colossus data centres. Google also agreed to pay $920 million each month.

So, Will Any Of This Change Things For Grok?
听
For everyday users, the Grok name is staying and one of the first announcements after the rebrand introduced 21 new flagship voices for Grok Voice.
The company said, 鈥淭oday, we鈥檙e releasing 21 new flagship voices for Grok Voice, joining the original five. All of them are multilingual and available now in the realtime Voice Agent API, the Text to Speech API, and the new Grok Voice Agent Builder.鈥�
SpaceXAI also explained the thinking behind the new collection, writing, 鈥淓ach voice was cast for a specific job: support, characters, commentary, advertising, education. Speech tags like [pause] and can be used to control the delivery.鈥�
Language support also received attention. The company said, 鈥淓very voice is natively multilingual, supporting all of Grok Voice鈥檚 25+ languages.鈥�
Existing voices also received an update. SpaceXAI said, 鈥淎ra, Eve, Leo, Rex, and Sal got an upgrade alongside the new voices. They鈥檝e been retrained with an improved recipe, so pacing, phrasing, and emphasis are more natural.鈥�

What Does One Brand Mean For The Ecosystem?
听
Putting everything under the SpaceXAI name gives Musk鈥檚 AI work one public identity instead of splitting products between SpaceX and xAI.
The company already owns the infrastructure, the chatbot, the social platform and the computing capacity. The new branding makes those pieces easier to recognise as belonging to the same ecosystem.
The SpaceXAI name gives an idea on where the company says it is spending much of its money. SpaceX鈥檚 filings show AI has become one of its biggest business priorities, and the rebrand gives that work the same name as the company building rockets, satellites and what it hopes will become computing infrastructure in orbit.
