SpaceX Has Option to Acquire Cursor for $60B — Colossus Compute Deal Already Active
SpaceX announced an option to pay $10B for Cursor's work or acquire it for $60B outright. xAI is already renting tens of thousands of chips to Cursor for model training; two senior engineers have departed for xAI.
SpaceX locked in an option to buy Cursor for $60B — putting the leading AI coding IDE on a path to Elon Musk's orbit.
What is it?
On April 21, 2026, SpaceX announced a partnership with Cursor giving it two choices: pay $10B for Cursor's 'product and distribution to expert software engineers', or exercise a full acquisition option for $60B at some point later in 2026. Cursor is the AI coding IDE used by developers at over half of the Fortune 500 — the most widely deployed AI coding tool alongside GitHub Copilot. The deal comes after xAI began renting 'tens of thousands of chips' from its Colossus supercomputer to Cursor for model training, and after two senior Cursor engineering leaders — Andrew Milich and Jason Ginsberg — moved to xAI and now report directly to Elon Musk.
How does it work?
The deal is structured as a two-step option, not a completed purchase. SpaceX frames the arrangement as combining Cursor's 'product and distribution to expert software engineers' with Colossus — described as equivalent compute power to one million Nvidia H100 chips. Cursor has already been migrating training workloads to xAI infrastructure. Cursor's valuation has risen from $2.5B in January 2025 to $29.3B in November 2025, with a new round expected to close at $50B — making the $60B acquisition option a modest premium over current funding-round price.
Why does it matter?
Cursor currently runs primarily on Anthropic's Claude models. An acquisition by SpaceX/xAI would almost certainly mean migrating toward Grok — restructuring the model relationship for millions of developers mid-workflow. The HN discussion (676 points, 830 comments) reflects genuine developer concern: Cursor is not just a code editor, it's load-bearing infrastructure for agentic coding stacks at many teams. Two senior engineers already gone to xAI and Colossus compute already flowing in make this more than a rumor. Governance of the most-used AI coding IDE is changing hands.
Who is it for?
Developers using Cursor daily; teams with Cursor Enterprise contracts; anyone tracking who controls the AI coding tools stack.
