Cursor is now a SpaceX company. The $60B all-stock acquisition of Anysphere, the company behind the AI code editor, became effective on 14 August 2026, according to a regulatory filing - two months after the binding agreement and a few weeks after SpaceX went public. The editor most vibe coders open every morning is, as of this month, a wholly owned subsidiary of a rocket company.
The deal
The structure was unusual from the start. In April, xAI secured an option to either buy Cursor outright for $60B or pay $10B for a collaboration. On 16 June, SpaceX - which had already folded xAI into itself earlier in the year - exercised the buy side. The price was paid entirely in SpaceX stock, roughly 391 million Class A shares, with Cursor's outstanding options and restricted stock assumed by the buyer. Cursor now sits inside the SpaceXAI division alongside Grok and X.
Cursor did not sit still while the paperwork cleared: the day before closing it bought Firetiger, its second acquisition after Graphite in December 2025. Neither price was disclosed.
The numbers
The valuation only makes sense against the revenue curve. Cursor went from roughly $100M to $4B in annualized revenue in about 16 months - one of the fastest ramps in software history - and its last priced round, a Series D in November 2025, valued it at $29.3B. Morgan Stanley analysts have suggested the deal could add as much as $13B to SpaceX revenue by 2027; that is a forecast, not a booking, and it assumes enterprise adoption holds its current pace.
A year ago the story was "an editor raised at $9B". Now the editor is a line item in a rocket company's S-1. The seat where software gets written turned out to be the most valuable seat in the building.

Cursor's own line is that it now has "access to the largest fleet of GPUs in the world", which it says means stronger models that are also cheaper to run. For the solo founder the practical questions are narrower: does the price hold, do the models keep improving, and does the product stay editor-first rather than becoming a front door for Grok? Cursor has said nothing about changes to plans or pricing. Grok 4.6 shipped the same day the deal closed, and the Grok Bot agent product a few days before - the integration pressure will be real.
What it signals
Three things. First, the vibe-coding tool is no longer a feature a platform can bundle away; it is an asset worth tens of billions to whoever controls the compute. Second, distribution and compute are consolidating - the same company now sells GPU capacity to Anthropic and Google and owns the editor. Third, for the four MIT co-founders, this is the payout that turns the "drop out and build a dev tool" story into the reference case for a generation of builders. Whether Cursor stays the builder's editor or becomes SpaceX's is the story of the next twelve months.
