On April 21, 2026, SpaceX and Cursor announced a collaboration to develop AI models using SpaceX’s Colossus supercomputer, with Cursor granting SpaceX an option to acquire the company for $60 billion later this year.
How the partnership combines Cursor’s software with SpaceX’s computing power
Cursor’s leading AI coding tools will be integrated with SpaceX’s Colossus system, which provides the equivalent of one million H100 GPUs for training large models. This combination aims to create what both companies describe as the world’s most useful AI for coding and knowledge work.
What the acquisition option means for both companies
As part of the agreement, Cursor has given SpaceX the right to buy the startup for $60 billion later in 2026, or alternatively pay $10 billion for the joint work completed under the partnership. The structure allows SpaceX to defer a full acquisition while securing access to Cursor’s technology and user base.
Why this deal reflects broader trends in AI development
The arrangement mirrors last year’s move when major AI startups began seeking infrastructure partnerships to avoid the prohibitive costs of building their own supercomputing clusters. By leveraging SpaceX’s existing Colossus investment, Cursor gains scale without bearing the full capital burden, while SpaceX positions itself as a provider of AI infrastructure beyond its own internal projects.
What is Colossus and why is it significant?
Colossus is SpaceX’s supercomputer cluster designed for AI training, reportedly scaled to the equivalent of one million H100 GPUs, which the company says will support frontier model development.
Could Cursor choose not to be acquired by SpaceX?
Yes, under the terms, Cursor retains the option to decline the acquisition and instead accept a $10 billion payment for the collaborative work completed under the agreement.
