SpaceX Acquires Cursor for $60 Billion in First Post-IPO Power Move

SpaceX is moving forward with its $60 billion acquisition of AI coding startup Cursor, the company confirmed in a regulatory filing Tuesday, making it the first major acquisition powered by SpaceX's newly public stock. According to the Associated Press, Cursor — made by San Francisco startup Anysphere — will become a wholly owned subsidiary when the deal closes in the third quarter of 2026.

SpaceX had secured an option in April to either buy Cursor outright for $60 billion or pay $10 billion for a partnership deal. The company chose the acquisition path, and the timing couldn't be more favorable: SpaceX shares have surged roughly 50% since their June 12 IPO at $135, giving the company a market capitalization that briefly touched $2.97 trillion on Tuesday, according to The Guardian.

Cursor isn't just another AI startup. It's the tool that helped spark the "vibe coding" movement, where developers describe what they want in plain language and let AI write the code. The Associated Press notes that the term was coined by a prominent AI researcher using Cursor's Composer feature combined with Anthropic's Claude Sonnet in early 2025.

But the real prize for SpaceX is Cursor's user base. The Guardian reports the platform has more than 1 million users, and as Harrison Rolfes, an analyst at PitchBook, told the publication: "Owning the tool that professional developers already trust daily is a faster path to enterprise AI revenue than winning the model race."

SpaceX's IPO filing also revealed that Cursor's access to developer data — including coding requests and design decisions — could help improve xAI's Grok model,.¹

The acquisition showcases the extraordinary power of SpaceX's newly public stock as a deal‑making tool. According to Fortune, SpaceX's stock appreciated by the entire $60 billion cost of Cursor in just a few hours on its first day of trading.

"The IPO gave SpaceX a valuation and a premium currency," Franco Granda, Senior Analyst at PitchBook, told.² "Signing a $60 billion all‑stock deal four days after listing, with the stock up more than 50% from the offer price, shows the playbook. SpaceX can now buy a company that size without touching cash, debt, or IPO proceeds, and the higher the stock runs, the cheaper the deal feels."

SpaceX opened at $135 per share on June 12 and closed Monday at $192.46, giving the company a market cap of $2.51 trillion — up roughly $740 billion from its IPO valuation in less than four trading days,.² The $60 billion Cursor deal represents less than a tenth of that gain.

For the developers who rely on Cursor daily, the big question is whether the tool will remain independent or become an xAI/Grok distribution channel. Cursor currently competes with Anthropic's Claude Code and OpenAI's Codex but has also relied on partnerships with both companies for the foundations of its technology, the AP notes.

When the deal was first announced in April, Cursor said the partnership with SpaceX subsidiary xAI would enable it to build future AI products using xAI's Colossus data center complex in Memphis, Tennessee. That access to compute is significant: The Guardian reports that a lack of access to computing power has hampered Cursor's growth, something SpaceX — as a datacenter owner — can solve.

Matt Britzman, senior equity analyst at Hargreaves Lansdown, summed it up: "Cursor does not have the scale of OpenAI or Anthropic, but it has built some very impressive coding models relative to cost. That makes this a positive move for SpaceX," he told.¹

The Cursor acquisition is the latest and largest move in a rapidly consolidating AI coding tools market. The competition for developer mindshare is fierce: Anthropic's Claude Code has captured strong developer loyalty, OpenAI continues to push Codex into enterprise workflows, and GitHub Copilot remains the incumbent with millions of users.

But Cursor carved out a unique position. It was Cursor's Composer, combined with Anthropic's Claude Sonnet, that a prominent AI researcher was using when he coined "vibe coding" in early 2025, per the AP. The tool's wide distribution to expert software engineers is what SpaceX described as a key driver of the acquisition's appeal.

Rolfes at PitchBook cautioned that the deal won't "close the gap" between xAI's models and those developed by Anthropic and OpenAI, but he emphasized that owning the developer toolchain may matter more than winning the model benchmark race,.¹

The deal is expected to close in Q3 2026, at which point Cursor will operate as a wholly owned SpaceX subsidiary. The immediate question is whether Cursor's existing model partnerships with Anthropic and OpenAI will survive the acquisition, or whether the tool will shift toward xAI's Grok as its primary AI backend.

What's clear is that SpaceX now has a direct line to the developer community — and a powerful new currency to fund its ambitions. As one analyst put it, the higher the stock runs, the cheaper every deal becomes. And with SpaceX shares continuing to climb, the Cursor acquisition may be just the beginning.
