Cursor's four cofounders stand to more than double their net worths through SpaceX's planned $60 billion acquisition of the AI coding startup. Forbes puts the anticipated net worth of each cofounder — Michael Truell, Aman Sanger, Sualeh Asif, and Arvid Lunnemark — at $2.7 billion upon closing.
Backing the founders for major gains are early investors who stand to collect enormous returns: Andreessen Horowitz's reported stake of around 10% translates to roughly $6 billion, while Thrive Capital's approximately 7% position would be valued at about $4.2 billion.
SpaceX agreed to acquire Anysphere, Inc., Cursor's parent company, in an all-stock deal that it expects to close in the third quarter of 2026, pending regulatory approvals. Under the merger terms, each share of Cursor stock will convert into SpaceX Class A common stock, with the exchange ratio based on SpaceX's volume-weighted average closing price over the seven trading days before closing.
The four cofounders met at MIT and founded Cursor in 2022. The startup originated as a coding tool for developers before expanding its scope. Annualized revenue hit $4 billion in early June, according to Forbes, after having reached $2 billion in February and $3 billion in late April. Driving part of that growth is Cloud Agents, a recently introduced product that autonomously handles demanding programming tasks over extended periods in the background.
The path to the SpaceX deal involved several other potential acquirers. Microsoft $MSFT examined a possible acquisition before ultimately declining to submit a formal bid. Cursor also turned down two separate approaches from OpenAI, with its leadership having prioritized independence. Cursor was in the middle of a $2 billion fundraising round — with Andreessen Horowitz, Nvidia $NVDA, and Thrive Capital set to participate at a valuation above $50 billion — when the SpaceX arrangement emerged. The $60 billion deal price exceeded that figure.
The arrangement traces back to April, when SpaceX locked in acquisition rights under terms that would obligate it to hand over $1.5 billion in breakup fees and $8.5 billion worth of computing resources should it choose not to follow through with the $60 billion purchase. Since then, SpaceX has said the two companies have worked together to develop a new AI model slated for release via Cursor and xAI's Grok platform. SpaceX folded xAI into its operations earlier this year.
