Elon Musk's SpaceX has officially acquired Anysphere, the startup behind the popular AI coding agent Cursor, for $60 billion in an all-stock transaction. The deal, announced on June 16, comes just days after SpaceX's blockbuster Nasdaq debut that pushed its valuation past $2 trillion.
The acquisition gives SpaceX's AI division, xAI — which Musk merged into the company earlier this year — a major foothold in the enterprise AI coding market. Cursor is one of the most widely used AI coding assistants among professional developers, competing directly with tools from Anthropic and OpenAI.
A Deal Months in the Making
SpaceX first signaled its interest in Cursor back in April 2026, securing an option to either acquire the company for $60 billion later this year or pay $10 billion for a partnership. The company chose the acquisition route, and the deal is expected to close in the third quarter of 2026, according to an SEC filing covered by Reuters.
If the deal falls through under specific circumstances, SpaceX will pay a $10 billion termination fee — reduced to $4 billion if antitrust issues are the cause.
Why Cursor?
Founded in 2022, Cursor has experienced explosive growth. The San Francisco-based startup crossed $1 billion in annualized revenue by late 2025 and now generates roughly $2.6 billion in business-to-business revenue, with enterprise sales climbing sharply. Its investors include Andreessen Horowitz, Thrive Capital, Nvidia, and Alphabet Google.
But despite its revenue growth, Cursor lacked the massive computing infrastructure that rivals like OpenAI and Anthropic command. That's where SpaceX's Colossus supercomputer — with the equivalent of one million H100 GPUs — comes in. Combining Cursor's AI models with Colossus raw compute power creates a formidable competitor in the AI arms race.
Market Reaction
SpaceX shares jumped 10% in early trading following the announcement, adding roughly $247 billion to its market capitalization. At $211.27 per share, the stock has climbed more than 56% above its IPO price of $135. The rally puts SpaceX on track to overtake Amazon in market value, making it the fifth-largest company by that metric.
The Bigger Picture: AI Coding Race Heats Up
AI-powered coding tools have become one of the first genuine revenue-generating categories in the AI industry. Companies are paying significant sums for tools that help developers write, review, and debug code faster. SpaceX had pitched its IPO investors an addressable market worth $28.5 trillion, with a large share expected from enterprise AI.
The acquisition pits SpaceX directly against Anthropic and OpenAI, both of which offer popular coding assistants. SpaceX said it plans to release a new AI model on Cursor soon, as well as Grok Build — xAI coding agent that has been jointly trained for several months using Colossus.
What This Means for Developers
For the millions of developers who use Cursor daily, the acquisition raises questions about the tool future direction. Cursor CEO Michael Truell said the team is "excited to partner with SpaceX to scale up Composer" — Cursor proprietary AI model — calling it "a meaningful step on our path to build the best place to code with AI."
Developers should expect tighter integration between Cursor and xAI Grok models, potentially unlocking capabilities that neither platform could deliver alone.
The acquisition is expected to close in Q3 2026, pending regulatory approvals.
