SpaceX has staked a claim in developer AI, securing an option to acquire AI coding start-up Cursor for $60bn later this year, or alternatively to pay $10bn for a strategic partnership, the companies said. The arrangement gives SpaceX access to Cursor’s models and distribution to professional developers while offering Cursor greater compute capacity to train larger systems.

Deal gives SpaceX a fast route into coder tools

SpaceX has secured an option to acquire Cursor, a rising AI company that builds tools to automate coding, for $60bn later this year, or alternatively to pay $10bn for a strategic partnership, the companies said. The arrangement effectively hands SpaceX access to Cursor’s models and distribution to professional developers while offering Cursor much greater compute capacity to train larger systems.

Cursor has emerged alongside firms such as OpenAI and Anthropic as a go-to service for developers seeking AI help with coding. SpaceX’s move is designed to accelerate its push into developer-facing AI tools and to close a gap with rivals that have already won early commercial traction in the market.

In a statement, SpaceX said the tie-up would pair Cursor’s products and reach with the firm’s training infrastructure, allowing the merged effort to push on with model development at a much faster pace.

Compute constraints and the lure of Colossus

Cursor had been reported to be raising capital to buy more compute capacity and had been pursuing a funding round near a $50bn valuation, though that process was paused when the SpaceX arrangement was announced.

Mastheads

SpaceX intends to make Cursor’s work run on xAI’s Colossus cluster in Memphis — equipment the company describes as a large H100-equivalent GPU cluster for training large models. Cursor said it would use xAI’s Colossus infrastructure to scale up model intelligence and accelerate training cycles that had been hampered by limited compute.

Cursor said the partnership is intended to remove the compute bottleneck that had been constraining model development and to speed up iterations on its developer-facing tools.

Where the option came from — and why it matters

The arrangement gives SpaceX a choice rather than a committed purchase: it can either exercise a $60bn acquisition option later in the year or pay $10bn to cement the partnership. That structure lets SpaceX lock in access to Cursor’s technology while maintaining flexibility ahead of a reported planned public offering.

For Cursor, the deal replaces private capital it had been courting and provides the compute and operational scale to expand its models quickly while preserving the option of a full takeover down the line. Key points:

  • The option structure avoids an immediate change of ownership that might affect SpaceX’s reported IPO plans.
  • Cursor gains access to a large training cluster and distribution to professional developers.
  • SpaceX gains developer-facing AI products and models without an immediate full acquisition.

Talent and consolidation

SpaceX’s AI push has been accompanied by hires from the AI sector. Two product engineering heads from Cursor, Andrew Milich and Jason Ginsberg, departed the start-up in March to join SpaceX, citing work on lunar projects and on xAI.

This move accelerates SpaceX’s push into developer-facing AI tools and helps close a gap with rivals such as OpenAI and Anthropic, which already have early commercial traction. For Cursor, the arrangement replaces private capital and provides the compute and distribution needed to scale its developer tools.

SpaceX must decide later this year whether to exercise the $60bn option or pay $10bn to cement the partnership — a choice that will determine whether it enters the developer tools market as owner or strategic partner.
