SpaceXAI says xAI has been folded into SpaceX following a February 2026 acquisition, with the former AI company now operating under the SpaceXAI name. The company also introduced Grok 4.5, a model aimed at coding, agentic tasks and knowledge work.
SpaceXAI has rebranded xAI under the SpaceXAI name after SpaceX acquired the AI company earlier this year.
According to an official xAI news page, SpaceX announced on February 2, 2026, that it had acquired xAI. Engadget reports that xAI is now officially known as SpaceXAI, describing the change as a rebrand that comes five months after the SpaceX-xAI merger. Engadget also reports that Elon Musk had described xAI as no longer operating as a separate company under SpaceX.
The change marks a formal shift in how the former xAI organization presents itself publicly. The company’s official acquisition announcement identifies SpaceX as the buyer, while Engadget’s report says the independent xAI brand has been replaced by SpaceXAI.
The provided sources do not include a detailed corporate structure, financial terms, or a full integration plan. They do, however, support the central point: SpaceX acquired xAI in February 2026, and the AI operation is now being presented publicly as SpaceXAI.
The sources also indicate that the rebrand is tied to a broader effort to combine SpaceX’s infrastructure ambitions with AI development. The official xAI acquisition page says the deal supports the acquisition part of the story, while Engadget frames the name change as the latest step after the merger.
SpaceXAI has also introduced Grok 4.5, according to an official company post titled “Introducing Grok 4.5.” The company says the model is built for coding, agentic tasks and knowledge work, and that it is available in Grok Build, Cursor and the SpaceXAI console.
Reuters, in a report carried by Investing.com, also says SpaceXAI launched Grok 4.5 for coding and agentic tasks. Reuters adds that Cursor said it partnered with SpaceXAI to train the model.
The SpaceXAI launch post says Grok 4.5 was trained alongside Cursor. That makes Cursor a notable part of the model’s rollout, though the provided sources describe this as a partnership rather than giving financial or acquisition details.
The confirmed facts from the cited sources are that SpaceX announced an acquisition of xAI on February 2, 2026; that xAI is now being identified as SpaceXAI; and that SpaceXAI has launched Grok 4.5 for coding, agentic tasks and knowledge work.
The sources do not independently substantiate every detail circulating around the change, including any precise deployment timeline for orbiting AI data centers or detailed claims about satellite-based compute infrastructure. Those ideas may be part of the broader context around SpaceX and AI infrastructure, but they are not established in the provided source excerpts.
For now, the concrete development is organizational and product-focused: the former xAI brand has been folded into SpaceXAI, and the company is using the new name to launch Grok 4.5 as an AI model aimed at software development and task-oriented workflows.
