The Four Students Who Sold a Code Editor for $60 Billion
Published November 1, 2026
In August 2026, SpaceX closed a $60 billion all-stock acquisition of Anysphere, the startup behind the AI coding tool Cursor, barely four years after four MIT students founded it. Cursor's annualized revenue had grown from $100 million in January 2025 to about $2.6 billion by June 2026, and its November 2025 funding round had valued it at $29.3 billion. The deal folded Cursor into SpaceX's AI unit, giving it access to one of the world's largest GPU fleets.
In June 2026, SpaceX agreed to buy Anysphere, the San Francisco startup behind the AI coding tool Cursor, in an all-stock deal valued at $60 billion. The transaction closed on August 14, 2026, making Cursor a wholly owned subsidiary of SpaceX's AI unit. For a company that had been founded barely four years earlier by four university students, the price tag was staggering: it was roughly double the valuation Anysphere had commanded in its last private funding round, just nine months before.
Cursor began in 2022 as Anysphere, founded by Michael Truell, Sualeh Asif, Arvid Lunnemark and Aman Sanger, four MIT students who set out to build a code editor with artificial intelligence at its core rather than bolted on. The editor itself launched in 2023, letting developers write, edit and refactor software by describing what they wanted in plain language. Over time it grew from a smart autocomplete into an agent platform: parallel agents that work through tasks on their own, a tool that reviews pull requests, and its own Composer models trained in-house.
The growth numbers explain why a rocket company wanted a code editor. Cursor passed $100 million in annualized revenue in January 2025, crossed $1 billion later that year, and by June 2026 its annualized business revenue stood at about $2.6 billion, according to Reuters data. By November 2025 it counted more than 50,000 teams as customers and served the majority of the Fortune 500, and a $2.3 billion Series D round that month, co-led by Accel and Coatue with Nvidia joining as a strategic investor, valued the company at $29.3 billion. Nvidia has said its own 30,000 developers commit three times more code using the tool.
The SpaceX relationship started as a model-training partnership in April 2026, structured with an unusual option: SpaceX could buy Cursor outright for $60 billion later in the year, or pay $10 billion for the joint work instead. In June, SpaceX exercised the purchase right in a binding all-stock agreement. The logic was about compute as much as code. Folded into SpaceX's AI unit, Cursor gained access to one of the largest GPU fleets in the world, including the Colossus supercomputer, while SpaceX gained a product already woven into the daily work of elite engineering teams.
The deal also raised a question that will decide how much of that $60 billion proves durable: can Cursor stay neutral about which AI models it offers while its owner competes in frontier AI? The company has long let developers use models from Anthropic, Google and others alongside its own. After the acquisition closed, OpenAI said it would stop supplying its models to Cursor, with a cutoff in November 2026, arguing it could not trust the new ownership to honor its terms. Cursor, meanwhile, kept buying, adding the code-review startup Graphite in December 2025 and Firetiger in August 2026.
For the four founders, a student side project became one of the largest startup acquisitions on record in under four years, and their shares converted into stock in a public company worth trillions. The wider lesson is about leverage: Cursor did not sell software to consumers one subscription at a time so much as it sold speed to the people who build everything else. When the tool that makes engineers faster becomes indispensable to the biggest companies in the world, the giants eventually come calling, and they do not haggle over the price.
The lesson: Build the tool everyone else builds with, and your payday arrives when the giants come calling.
