xAI has officially been rebranded as SpaceXAI, marking the final step in Elon Musk's plan to merge his artificial intelligence company into SpaceX.
The change follows SpaceX's acquisition of xAI, X, and its flagship AI chatbot Grok earlier this year. Musk had previously said xAI would cease operating as a standalone company, with all of its AI products becoming part of SpaceX under the SpaceXAI brand.
On Monday, the company's official X account changed its username from xAI to SpaceXAI and unveiled a new logo showing the original xAI branding transforming into the new identity.
The rebrand comes shortly after SpaceX's record-breaking IPO in June, which raised $75 billion at a valuation of roughly $1.77 trillion, making it the largest public offering in history.
Although SpaceX is best known for its rockets and Starlink satellite internet network, its IPO filings revealed the company is investing heavily in artificial intelligence. SpaceX spent $12.7 billion on AI in 2025, more than three times its combined spending on its space and connectivity businesses.
While the AI division is not yet profitable, SpaceX believes it represents its biggest long-term opportunity, describing the market as the largest "in human history." The company also plans to launch AI compute satellites—space-based data centers—as early as 2028.
SpaceX has already secured major AI infrastructure customers, including Anthropic, which agreed to pay $1.25 billion per month for computing capacity at its Colossus data centers, and Google, which agreed to pay $920 million per month.
