SpaceX finalized the acquisition of Cursor, an emerging company focused on artificial intelligence programming, for US$ 60 billion this Friday, the 14th. This deal, which was initially announced in April and formalized in June, intensifies the union between the two corporations.
The collaboration between the companies was already yielding results before the transaction was completed. Cursor was involved in the training process of recent versions of Grok, gained access to the Colossus supercomputer, and integrated its services into the artificial intelligence products offered by SpaceX.
This cooperation primarily covers three aspects: model development, computational capacity, and product distribution. The connection between the companies became more robust even before the official completion of the purchase.
One of the central points of the partnership was the development of Grok, SpaceX's artificial intelligence model. Cursor worked side-by-side with the team responsible for the system in training Grok 4.5, which was previously launched, using a vast amount of data, estimated by the startup itself to be trillions of tokens from its archive.
This work had a notable characteristic: it was the first time Cursor created a model that was not exclusively dedicated to software engineering. Alan Sanger, the company's co-founder, also publicly mentioned the collaboration with SpaceX's artificial intelligence team.
Cursor's contribution did not stop with Grok 4.5; it also assisted in the training of Grok 4.6, which SpaceX presented on Wednesday, the 12th.
Another crucial aspect of the partnership was access to SpaceX's computing infrastructure. Cursor began using Colossus, a supercomputer equipped with 200 thousand Nvidia GPUs, which is also used by Anthropic. For the startup, this structure solved a restriction that prevented the increase of its training efforts. In the announcement made in April, Cursor stated that access to Colossus would enable significant growth in the capacity of its models.
Integration also progressed in products intended for end-users. On Tuesday, the 11th, SpaceX launched its new artificial intelligence agent, named Grok Bot. This product became accessible to SuperGrok Heavy subscribers and was also offered to customers of Cursor Ultra and Cursor Premium Teams plans.
Additionally, current versions of Grok were incorporated into the Cursor system as top-tier models. This move demonstrates that the relationship between the companies went beyond AI training and infrastructure, extending to the offering of functionalities to users.
The closing of the acquisition occurred after a period in which the companies were already operating in close collaboration. During its earnings conference call in August, Elon Musk chose not to detail the partnership at that time, stating that he did not wish to anticipate information while the regulatory process was still pending completion.
With the finalization of the purchase, the relationship, which began as a partnership, officially advances to a new phase under SpaceX's ownership.
