Mind The Agentic Action Gap: Stop Losing Money With AI Agents
SpaceX has announced a new agreement with Cursor, a San Francisco-based AI coding start-up, that gives the rocket company the option to acquire Cursor for $60 billion later this year.
The announcement, made Tuesday via social media, sent ripples through the AI and tech investment communities, given both the staggering price tag and the unlikely pairing of a rocket company with a code-writing software start-up.

What's in the Deal?
The agreement is structured with two potential outcomes for SpaceX:
| Option | Cost |
|---|---|
| Acquire Cursor outright | $60 billion |
| Pay for the partnership without acquisition | $10 billion |
In its X post, SpaceX said the partnership would "allow us to build the world's most useful" AI models.

The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will…
For Cursor, the deal offers something the start-up has openly struggled to secure on its own: computing power. In a blog post Tuesday, Cursor acknowledged that its lack of access to hardware for training AI models had "bottlenecked" its growth.
Through SpaceX, Cursor will gain access to xAI's Colossus supercomputer — described as capable of running 200,000 H100/H200 GPUs — which the start-up says will help it "dramatically scale up the intelligence of our models."

Why Would a Rocket Company Buy a Coding App?
SpaceX's core businesses — orbital rocket launches and Starlink satellite internet — seemingly have little obvious overlap with tools that help software engineers write code faster.
But the deal makes more sense when viewed through the lens of Musk's broader AI ambitions.
- Musk co-founded OpenAI, the company behind ChatGPT, before departing its board
- He later launched xAI, which developed the Grok chatbot
- SpaceX acquired xAI in February, creating a combined entity that valued itself at $1.25 trillion
- SpaceX has also announced plans for AI data centers in orbit and an AI chip factory
Musk has been explicit about his vision. In a letter to SpaceX employees following the xAI acquisition, he wrote: "In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun's energy would require over a million times more energy than our civilization currently uses!”
He has argued that becoming a multiplanetary species will only be possible once data centers are deployed in space to harness solar energy at scale.
Cursor's Rise — and the Competitive Pressure It Faces
Founded in 2022 by four MIT alumni — Michael Truell, Sualeh Asif, Aman Sanger and Arvid Lunnemark — Cursor quickly established itself as one of the hottest companies in the AI coding space.
Key milestones include:
- Reached $100 million in annual recurring revenue within 12 months
- Raised $3.4 billion in venture funding from Thrive Capital, Andreessen Horowitz and Accel
- Achieved a $29.3 billion valuation as of November 2025
But despite its rapid ascent, Cursor has faced mounting pressure from well-funded rivals. Anthropic, the AI safety company, has reported surging revenue from Claude Code, its enterprise-focused coding tool. OpenAI has invested heavily in Codex and has been aggressively courting business customers. For a start-up — however well-funded — competing against two of the most capitalized AI companies in the world is an increasingly steep climb.
Cursor CEO Michael Truell shared his optimism about the deal on X, writing, "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."

The xAI Connection
The deal also patches over a significant gap in Musk's AI portfolio. xAI had been developing its own coding tools but fell behind OpenAI and Anthropic, experiencing what sources described as an employee exodus. In March, xAI hired Andrew Milich and Jason Ginsberg — two former Cursor leaders — in an attempt to reboot those efforts.
Following those hires, Musk posted publicly that "xAI was not built right first time around, so is being rebuilt from the foundations up. Same thing happened with Tesla."

Acquiring Cursor outright, rather than attempting to rebuild from within, would give SpaceX and xAI an immediate and proven product with an established user base among professional software engineers.
IPO Timing Adds Intrigue
The announcement comes as SpaceX is preparing for what analysts expect to be one of the largest initial public offerings in history, potentially arriving as early as June. Whether SpaceX intends to close a Cursor acquisition before or after going public remains unclear — and the $60 billion price tag would rank among the largest tech acquisitions ever recorded if completed.
