SpaceX has completed its acquisition of Cursor, the AI coding startup, in a deal valued at $60 billion. The transaction closed on Friday, August 14, 2026, completing a process that began in April and became public in June.
The deal brings Cursor into SpaceX after the companies first teamed up in April 2026. Their early work focused on Cursor’s model training efforts, creating a working relationship before the companies announced plans for an acquisition two months later.
From Partnership to Acquisition
SpaceX and Cursor announced the acquisition in June 2026, but the companies had already started working together in April. That timeline shows how the relationship moved from a partnership to a purchase within the same year.
SpaceX paid $60 billion for Cursor. The acquisition now stands as a completed transaction, with SpaceX confirming the closing date as Friday, August 14, 2026.
The purchase also connects Cursor to a larger AI structure around SpaceX. Elon Musk’s SpaceX merged with his AI company, xAI, earlier in 2026. That merger came before SpaceX completed its purchase of Cursor.
The connection between SpaceX, xAI, and Cursor has already produced new AI models. SpaceX and Cursor released Grok 4.5 and Grok 4.6 together, linking Cursor’s coding work with the Grok model line.
What Cursor and SpaceX Built Together
Grok 4.5 was designed to excel at coding, agentic tasks, and knowledge work. Those areas point to software that can support programming, handle tasks through AI agents, and work with information beyond simple code generation.
Grok 4.6 was trained to handle real life tasks, including general coding, web development, and computer-aided design. Its training focus gives the model a broader range of work than coding alone, covering both digital projects and design tasks.
Cursor said Grok 4.6 provides an early look at what it can build with SpaceXAI. That statement ties the model to the companies’ work together and frames the release as an early example of the results from the partnership.
The two model releases came before the acquisition was completed, making them part of the deal’s development rather than a separate event. Cursor and SpaceX first worked together in April, announced the purchase in June, and completed it in August.
A Deal Completed After Regulatory Caution
Before the closing, Elon Musk avoided giving details about the SpaceX-Cursor partnership during SpaceX’s August earnings call. He said, “We don’t want to jump the gun on regulators for closing the acquisition.”
That comment came before the transaction reached its final stage. The acquisition has now closed, ending the period between the June announcement and the August 14 completion date.
SpaceX’s purchase of Cursor therefore brings together three connected parts of the 2026 AI story: a partnership that began in April, an acquisition announced in June, and a completed $60 billion transaction in August.
Cursor enters SpaceX after releasing Grok 4.5 and Grok 4.6 with the company. The models’ focus on coding, agentic tasks, knowledge work, web development, and computer-aided design shows the work the companies had already begun before SpaceX formally completed the acquisition.
