On April 21, 2026, SpaceX and Cursor AI (the coding AI startup under Anysphere Inc.) announced an unusual strategic partnership. Under the deal, SpaceX secured an option to acquire Cursor by the end of 2026 for $60 billion, or pay $10 billion as consideration for the joint development work. The collaboration combines Cursor's native AI code editor with SpaceX's Colossus supercomputer, which targets a capacity equivalent to one million H100 GPUs. The two companies claim they will build 'the world's best AI for coding and knowledge work.'
Deal Structure and Financial Details
SpaceX confirmed the agreement in a post on X, stating it would allow both firms to build 'the most useful models in the world.' The New York Times had earlier reported, citing sources, that SpaceX agreed to buy Cursor for $60 billion, but SpaceX revised that framing, clarifying it is an option, not a completed acquisition. Cursor, developed by Anysphere Inc., was founded in 2022 by four MIT classmates: Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger. The product is a fork of Visual Studio Code with deep AI integration, enabling developers to write, edit, and generate code using natural language commands. Truell expressed interest in scaling Cursor's Composer model, and the SpaceX computing deal gives Anysphere access to training infrastructure it could not easily replicate independently.
The deal structure is unusual. SpaceX holds a call option to acquire Cursor outright by end of 2026 for $60 billion, or pay $10 billion as joint work compensation. This gives SpaceX flexibility while providing Cursor with significant financial security before any acquisition is completed.
Cursor's Rapid Growth
Cursor has grown fast. The company surpassed $1 billion in annualized recurring revenue (ARR), with year-over-year growth exceeding 9,900%. Over one million developers use the platform daily, and 67% of Fortune 500 companies have adopted it, collectively generating more than 150 million lines of enterprise code per day. In November 2025, Cursor raised $2.3 billion in a Series D round at a $29.3 billion valuation, with investors including Andreessen Horowitz, Accel, Coatue, Thrive Capital, Nvidia, and Google. In April 2026, the company was in advanced talks for another $2 billion round at a valuation above $50 billion, with the same core investors participating.
SpaceX's AI Strategy and Colossus Supercomputer
SpaceX acquired Elon Musk's independent AI company xAI in February 2026 in an all-stock transaction that valued the combined entity at approximately $1.25 trillion. That deal brought the Colossus supercomputer, originally developed by xAI, under SpaceX's umbrella. Since then, SpaceX has described plans to expand Colossus to orbital data centers. The partnership with Cursor builds on this foundation: SpaceX now controls significant compute capacity and is directing it toward software tools used by professional developers, a segment where OpenAI and Anthropic are also actively competing.
SpaceX set a record for annual launches in 2025 with roughly 165 orbital missions and secured the majority of U.S. national security launches for fiscal year 2026. The company is preparing for what analysts expect to be one of the largest initial public offerings in history, with a possible listing as early as June 2026. SpaceX also holds 8,285.45 BTC on its balance sheet, monitored by Arkham Intelligence. If it were public today, it would rank as the 15th largest publicly listed bitcoin holder.
Option Period and Outlook
No details on employee transfers or organizational integration between SpaceX and Cursor have been disclosed. The option period is expected to extend through the end of 2026. Cursor previously declined an acquisition interest from OpenAI. Whether SpaceX exercises the $60 billion option will depend on the progress of joint model development in the coming months. For now, however, both companies remain private, unless SpaceX decides to act.
