today, june 16, 2026, spacex signed a merger agreement to acquire cursor (anysphere) in an all-stock deal valuing the company at $60 billion. cursor will become a wholly owned subsidiary of spacex. the deal is expected to close in q3 2026, pending regulatory approval
it comes just four days after spacex's blockbuster nasdaq ipo, and gives spacex's ai arm a much-needed foothold in the ai coding tools market, where it had been trailing anthropic, openai, and microsoft
but today's announcement didn't come out of nowhere. the two companies have been circling each other for months, with the relationship deepening in steady, deliberate steps
• march 2026. two cursor engineering leads, andrew milich and jason ginsberg, leave to join spacex. first concrete tie between the two companies.
• april 21, 2026. spacex and cursor announce a combined deal: a compute partnership giving cursor access to xai's colossus supercomputer in memphis, plus an option for spacex to buy cursor for $60 billion later in the year. if spacex walks away, it owes cursor a $10 billion break fee. spacex can exercise the option in the 30 days after september 30, or seven trading days after its ipo, whichever comes first.
• late may 2026. grok v9-medium finishes training, using cursor workflow data (real developer sessions from the editor) as part of its corpus. the partnership starts producing actual models.
• june 16, 2026. spacex exercises the option. merger agreement signed. closing expected in q3 2026.
the relationship moved fast – from a quiet engineer transfer in march to a full acquisition in june, barely three months. each step locked the two companies in tighter: people first, then compute and an option, then a shipped model trained on cursor data, then the buyout. by the time spacex exercised, the integration was already deep enough that the merger was less a surprise than a formality

SpaceX has exercised the option to acquire @cursor_ai in an all-stock transaction with the goal of building the world’s most useful AI models.
