SpaceX has finalized its $60 billion deal with Cursor, which had acquired a company the day prior.

      SpaceX confirmed its completion in a regulatory filing. Bloomberg's Carmen Arroyo and Natasha Mascarenhas reported the deal's closure. The news desk covered the binding agreement in June when SpaceX submitted an 8-K form and indicated that it expected the completion in the third quarter, pending regulatory approval. That approval has now been granted, aligning with the timeline outlined in the filing.

      Cursor published its own statement the same day, consisting of two paragraphs on strategy and one key sentence. “We will have access to the largest fleet of GPUs in the world, giving us the compute to build stronger models that are also more economical to run,” the company stated. The implication is commercial, translating to more advanced models at lower costs for clients. Moreover, it places the timeline of the process earlier than suggested by the filings, signaling that the acquisition wraps up a partnership initiated in April when Cursor announced collaboration with SpaceXAI to expedite model training. Cursor highlighted Grok 4.6, released on Wednesday, as an initial demonstration of their joint capabilities.

      Notably absent from the statement were any figures, leadership changes, or product commitments apart from that specific model. On August 13, just a day before the deal’s closure, Cursor announced that Firetiger had joined the company, following its acquisition of Graphite in December 2025. A company being acquired for $60 billion was still actively acquiring just before the deal was finalized, which is unusual and indicates the expectations both sides have for the partnership. Cursor retains its name, blog, and its own transactions, while the legal entity is Anysphere. Its vision for the future remains deliberately focused, with SpaceX responsible for building the computing capability, and Cursor positioned as a provider of useful intelligence.

      The target of the acquisition is coding, with specific competitors named. The deal is part of Musk’s strategy to gain a competitive edge over Anthropic and OpenAI, as reported by Bloomberg. SpaceXAI required support as it previously experienced restricted business adoption and underwent layoffs and restructuring. Cursor brings to the table what SpaceXAI has been missing. Its assistant, launched in 2023, quickly became one of the fastest-growing startups historically and has been central to the vibe-coding era.

      The two companies have already collaborated on product releases. Grok 4.5 was introduced in July as an Opus-class model designed for coding, legal, and finance tasks, priced competitively against rivals. Grok Bot was launched on August 11 and operates like a team of agents managing assignments throughout the day.

      A noteworthy aspect of the competition is that Anthropic, one of the intended targets of this deal, is also a customer. In May, it agreed to pay SpaceX approximately $45 billion for computing resources, estimated at around $15 billion a year, according to Axios at the time. Google has entered into a similar agreement with SpaceX for computing services, meaning the same infrastructure supports both SpaceX’s own models and those of its competitors. This is not contradictory but highlights the new business model SpaceX is pursuing. Selling computing resources finances the development of its models.

      Musk informed SpaceX staff this month that the company "must succeed on the software front" and provided a timeline. During an all-hands meeting, he stated that AI revenue is expected to surpass earnings from rockets by September and significantly exceed other revenue streams by the fourth quarter. Considering the $60 billion acquisition in that context reveals the rationale behind it. A rocket company is investing towards a software business that it anticipates will become its largest within just weeks.

      Investors reacted positively to the deal's completion, with SpaceX shares increasing by about 3.6% to $136.20. The company has only had a share price since this summer; its listing was just days old when the Cursor acquisition was made official in June.

      As for the founders, the four MIT co-founders transitioned to billionaires upon completion. While this aspect of the story is significant, it is not as impactful as the transfer of the team and computing resources. Cursor engineers now have access to SpaceX's inventory of advanced AI chips. Cursor's ambition has been described as shifting from completing simple lines of code to developing AI teammates capable of handling genuine work. Whether this access leads to lower operational costs remains uncertain. Cursor claims it will, and it has a direct way to test this.

      Owning the chips alters the unit economics rather than the product itself; the models still need to justify running.

      Cursor is not escaping a difficult market with this acquisition. Value in AI coding is shifting from the model itself to the framework that organizes it. Reports indicate that enterprises are adopting open-source frameworks that direct tasks to more affordable models, with some users claiming 97% cost reductions. This supports the rationale behind acquiring the GPUs. If the competition hinges on cost per task, a company that owns its computing resources holds an advantage. Conversely, there is skepticism about the wisdom of paying $
