SpaceX Seals $60B Option to Acquire Cursor in AI Coding Deal
SpaceX announced on April 21 that it has struck a deal giving it the right to acquire Cursor for $60 billion — or pay $10 billion for joint AI coding development. Here is what developers need to know about the biggest potential acquisition in AI coding history.

SpaceX Acquires Option to Buy Cursor for $60B, Launching Major AI Coding Partnership
SpaceX announced on Tuesday that it has struck a landmark deal with AI code editor startup Cursor, giving Elon Musk's rocket-and-AI conglomerate the right to acquire the popular developer tool for $60 billion — or pay $10 billion for joint development work if it opts not to.
The announcement, made via a post on X, described a partnership focused on building "the world's best coding and knowledge work AI." The deal comes as SpaceX prepares for what could be the largest IPO in history, and as xAI — now fully integrated into SpaceX after a February merger valued at $1.25 trillion — struggles to keep pace with Anthropic and OpenAI in the race for AI coding dominance.
"SpaceXAI and @cursor_ai are now working closely together to create the world's best coding and knowledge work AI," SpaceX said in the post. Cursor CEO Michael Truell responded on X: "Excited to partner with the SpaceX team to scale up Composer. A meaningful step on our path to build the best place to code with AI."
What the Deal Actually Includes
The partnership gives Cursor access to SpaceX's Colossus supercomputer — a training cluster the company claims is equivalent to one million Nvidia H100 chips. Cursor has been explicit about why this matters: in a blog post announcing the partnership, the company said it has "wanted to push our training efforts much further, but we've been bottlenecked by compute." With Colossus, Cursor plans to "dramatically scale up the intelligence of our models."
The financial structure is unusual. SpaceX will either:
- Acquire Cursor outright for $60 billion later this year, or
- Pay $10 billion for the collaborative development work if it chooses not to acquire
This dual-path structure gives SpaceX significant flexibility ahead of its IPO while locking in a deep working relationship with one of the fastest-growing developer tools companies on earth.
The Compute Angle: Why Developers Should Care
Cursor today is entirely dependent on third-party models — it resells access to Anthropic's Claude and OpenAI's GPT models to developers. That arrangement is increasingly awkward as both Anthropic (Claude Code) and OpenAI (Codex) launch their own competing coding tools and vie for the same developer market.
This partnership gives Cursor a path toward training proprietary models on Colossus. If it works, developers could eventually get Cursor-native models not subject to the terms, pricing, and availability limits of third-party APIs. That would fundamentally shift the competitive dynamics of the AI coding market.
xAI's Grok models have "lagged behind in coding," as Musk himself acknowledged at a recent conference. Integrating Cursor's distribution — used by developers at Stripe, NVIDIA, Dropbox, and Box, with over $1 billion in ARR — with Colossus compute is SpaceX's most direct bet yet on catching up.
How We Got Here
This deal did not come out of nowhere. The paper trail goes back several months:
- March 2026: Two of Cursor's most senior engineering leaders, Andrew Milich and Jason Ginsberg, departed to join xAI, reporting directly to Musk.
- Early April 2026: Reports emerged that xAI had begun renting Colossus compute to Cursor for model training.
- April 17, 2026: TechCrunch reported Cursor was in talks to raise $2 billion at a $50 billion+ pre-money valuation, with a16z, Thrive, and Nvidia expected to participate.
- April 21, 2026: SpaceX publicly announced the partnership and acquisition option, pre-empting New York Times reporting on the deal.
Cursor's valuation trajectory is staggering: $2.5 billion in January 2025, $9 billion by May 2025, $29.3 billion after its $2.3 billion Series D in November 2025, and now a $60 billion acquisition price — a roughly 24x jump in approximately 18 months.
What Is Not Yet Clear
SpaceX has not disclosed:
- Whether the $60 billion acquisition or $10 billion payment would be settled in cash or SpaceX stock
- The exact timeline for when SpaceX must exercise the acquisition option
- Whether a deal would happen before or after SpaceX's IPO, currently expected as early as June 2026
- Any impact on Cursor's existing investor round, including whether the a16z-led $2 billion fundraise will still proceed
For developers, the critical open question is whether this partnership changes what you actually experience in the editor today. There has been no announcement of new Cursor features, pricing changes, or model availability tied to this deal. For now, it is a strategic signal, not a product update.
The Competitive Picture
This deal is the clearest sign yet that the AI coding market is consolidating around infrastructure bets, not just model quality. With Anthropic pushing Claude Code, OpenAI shipping Codex with agentic features, and now SpaceX/xAI locking in Cursor, the developer tool market is rapidly becoming a proxy war between the biggest AI labs.
Cursor's 300-person team and its $1 billion ARR run rate give SpaceX immediate distribution to the most active professional developer base in AI. What SpaceX gets in return is a product developers already trust — something xAI has not been able to build on its own. The question for developers is whether Cursor's model independence — a key reason many chose it over vendor-locked alternatives — survives a full acquisition.
