Quick Facts
- SpaceX closed its $60 billion all-stock acquisition of Cursor on Aug. 15, 2026, the largest venture-backed startup acquisition ever recorded.
- SpaceX issued 389 million Class A shares to complete the deal, representing 3.4% dilution at the company’s IPO valuation.
- Cursor reported roughly $2.6 billion in annualized revenue at the time of closing, with enterprise sales rising.
SpaceX officially closed its $60 billion acquisition of AI coding startup Cursor on Aug. 15, 2026, completing the largest purchase of a venture-backed startup in history. The deal was structured entirely in stock, with SpaceX issuing 389,289,254 Class A shares through its wholly owned subsidiary X67 Inc. to acquire Anysphere, Inc., the legal entity behind Cursor.
Cursor posted the announcement on its blog: “Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world’s most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more.”
The path to closing spanned several months. In April 2026, xAI, which SpaceX had already absorbed in a $1.25 trillion all-stock merger, announced it had the right to acquire Cursor for $60 billion or pay $10 billion for a joint work arrangement. SpaceX formalized the acquisition agreement on June 16, just days after its Nasdaq debut at $135 per share in what was the largest IPO in history at $75 billion raised.
Cursor CEO Michael Truell described the deal as “a meaningful step on our path to build the best place to code with AI,” adding that he was excited to scale the company’s Composer model with SpaceX’s resources.
Founded in 2022 by Truell and three MIT classmates, Cursor helped popularize AI-assisted software development, reaching $1 billion in annualized revenue by late 2025 and growing to approximately $2.6 billion by the time the deal closed. The company built a coding tool that allows developers to generate, edit, and review code using AI models.
Despite that revenue growth, Cursor’s market share had slipped. Spending data from Ramp showed its share of the AI coding category fell from 41% in June 2025 to about 26% in May 2026. Anthropic now controls roughly half the category.
The acquisition gives Cursor access to what SpaceX describes as the largest fleet of GPUs in the world. Cursor had previously noted it was “bottlenecked by compute,” writing in April that each additional layer of computing had produced meaningfully stronger models. That constraint disappears as a SpaceX subsidiary.
SpaceX had already begun using Cursor’s data before the deal closed. Grok 4.5, released in July 2026, was jointly trained on trillions of tokens of Cursor data capturing how developers interact with codebases. SpaceX released Grok 4.6 on Aug. 12, three days before the deal closed.
Bret Greenstein, Chief AI Officer at West Monroe, drew a comparison to Tesla’s supply chain model: “SpaceX appears to be following a pattern we’ve already seen at Tesla with vertical integration. AI also requires the infrastructure to support it, including energy, data centers, and connectivity, all of which tie directly to SpaceX’s broader goals.”
The all-stock structure kept cash off the table. Investor Bill Ackman noted publicly that stock-based deals cost the acquirer less in real dilution than the headline figure implies. At SpaceX’s IPO valuation, the $60 billion in shares equated to 3.4% dilution. The deal also carried a $10 billion termination fee under certain conditions and a $4 billion fee if antitrust issues had blocked closing.
One day before closing, Cursor announced that a company called Firetiger had joined the firm, following its December 2025 purchase of Graphite. The continued acquisition activity on the eve of the deal suggests SpaceX plans to let Cursor operate with significant independence.
Elon Musk told SpaceX staff that AI will represent “99% of the value of SpaceX” within four to five years and that digital intelligence would eventually outpace biological intelligence as computing scales.
