Four Days After Its Record IPO, SpaceX Is Buying the AI Coding Startup Cursor for $60 Billion.

On June 16, 2026, SpaceX signed a definitive agreement to acquire Anysphere— the company behind the popular AI coding agent Cursor — for roughly $60 billion in an all-stock deal, according to a securities filing and reporting from CNBC and Reuters. It is the first major acquisition SpaceX has made with the stock it minted in its record IPO just four days earlier.

Cursor was founded by four MIT students in 2022. It grew from an $8 million seed round into one of the fastest-scaling software companies on record — valued at $9.9 billion in mid-2025, $29.3 billion last November, and now $60 billion. The price is not a surprise: SpaceX disclosed a call option in April that let it buy the company for exactly that figure.

The logic runs through Elon Musk’s AI consolidation. SpaceX absorbed his AI lab xAI — maker of the Grok models — earlier this year, and xAI has trailed Microsoft, Anthropic, and OpenAI in the booming market for AI coding tools. Buying Cursor hands it an enterprise-adopted product and a distribution channel overnight. This page lays out the deal, what Cursor actually is, why SpaceX wanted it, and the antitrust questions trailing it.

The structure, per SpaceX’s Form 8-K: a SpaceX subsidiary called X67 Inc. merges into Anysphere, which survives as a wholly owned SpaceX subsidiary. Every Anysphere share converts into SpaceX Class A common stock, with the exact share count fixed by SpaceX’s seven-trading-day volume-weighted average price right before closing — a mechanism that locks the $60 billion value regardless of how the stock moves in the interim. It is an exercise of the option SpaceX disclosed in April, which gave it the choice to buy Anysphere outright for $60 billion or pay $10 billion for the partnership work alone. It chose to buy.

Cursor is an AI coding agent and development environment — software that lets engineers edit code, search a codebase, run commands, and complete programming tasks through natural-language instructions, powered by Anysphere’s in-house model, Composer. It was founded in 2022 by four MIT students: Michael Truell (the CEO, now 25), Sualeh Asif, Aman Sanger, and Arvid Lunnemark. Its rise has been near-vertical: $100 million in annualized revenue in early 2025, more than $500 million by that summer, past $1 billion by late 2025, and a company-stated $2 billion by February 2026. Backers have included Thrive Capital, Andreessen Horowitz, Accel, Coatue, Nvidia, and Google.

Three forces converge here. First, catch-up: after folding xAI into SpaceX, Musk’s AI effort lacked a competitive coding product while rivals shipped GitHub Copilot, Anthropic’s Claude Code, and OpenAI’s Codex; Cursor is an instant, enterprise-adopted answer. Second, compute: Cursor has been bottlenecked buying outside compute, and folding it into xAI’s Colossus supercomputer lets it scale Composer in-house. Third, currency: SpaceX’s June 12 IPO — the largest in history, valuing the company near $1.77 trillion — gave it a freshly liquid, publicly traded stock to spend, which is how a $60 billion all-stock deal becomes possible four days later.

The collaboration was telegraphed publicly two months before the acquisition, when SpaceX framed the partnership this way in April:

A $4 billion regulatory termination fee — on top of the standard $10 billion break fee — is its own statement: SpaceX is pricing in real antitrust risk. The companies began working together before the deal closed, and xAI’s general counsel reportedly told staff to limit contact with Cursor employees to avoid “gun-jumping” concerns. CNBC also reported that Microsoft had examined buying Cursor before SpaceX moved. Whether regulators see a vertical tie-up that strengthens competition against Microsoft and OpenAI, or a consolidation that should worry them, is the open question the termination fee is hedging against.

“Excited to partner with the SpaceX team to scale up Composer. A meaningful step on our path to build the best place to code with AI.”

Strip away the spectacle and the deal is a clean strategic trade: SpaceX spends freshly minted public stock to buy distribution and talent in the one AI market where Musk’s empire was behind, and Cursor trades independence for unlimited compute and a balance sheet that can outspend anyone. The risks are equally clear — an all-stock price tied to a four-day-old, $1.77 trillion valuation, and an antitrust review the parties are already paying to insure against. The deal is signed; whether it closes on these terms in the third quarter is now a question for regulators, not founders.
