SpaceX just executed the largest acquisition of a venture-backed startup in history, exercising its option to buy Cursor parent Anysphere for $60 billion in an all-stock deal that pulls a rocket company straight into the center of the AI coding war. According to CNBC, the deal is expected to close in the third quarter.
The move, disclosed in a Form 8-K filed with the SEC on June 16, lands days after SpaceX completed the largest IPO ever, raising $75 billion.
With the new public-market currency and a soaring share price, Elon Musk’s company is spending equity to own one of the fastest-growing software products on the market.
SpaceX Pays $60 Billion In Stock For An AI Coding Leader
SpaceX secured an exclusive option in April to acquire Anysphere or walk away for a $10 billion breakup fee. On June 16 it exercised that option and signed a $60 billion merger agreement with Anysphere and its subsidiary X67. Cursor becomes a wholly owned SpaceX subsidiary once the deal closes, currently expected in the third quarter of 2026.
Anysphere shareholders will receive SpaceX Class A stock priced on the company’s average share price over the seven trading days before close. If the deal collapses under specific conditions SpaceX owes $10 billion, and $4 billion if antitrust regulators block it.
The price tag reveals how the market now values agentic AI software.
Founded in 2022 by Michael Truell and three MIT classmates, Cursor reached $3 billion in annualized revenue by late April. Per TechCrunch, weeks ago Cursor was reportedly raising a $2 billion round at a $50 billion valuation.
SpaceX paid a steep premium to take it off the table entirely.
SpaceX Wants Cursor To Give Grok A Coding Engine
The strategic logic runs through xAI, which SpaceX absorbed in February. Grok has struggled to break into the frontier tier of AI models, a tier currently led by Anthropic’s Claude and OpenAI’s GPT line.
Cursor changes that math.
For the past several months SpaceXAI and Cursor have been jointly training a model that will ship inside Cursor and Grok Build, handing Musk’s AI unit a distribution channel into millions of professional developers and a product that already wins daily usage.
That distribution matters as much as the technology.
Cursor lives inside the workflow of expert software engineers, the exact users who decide which AI tools become standard. Pair that footprint with SpaceX’s Colossus supercomputer, reported at roughly one million H100 equivalents, and you get training scale plus a captive, high-value audience under one roof.
SpaceX Reframes The Race Against Anthropic And OpenAI
For Anthropic and OpenAI, the competitive picture shifted overnight. Both run their own coding products, Claude Code and Codex, and both are expected to go public this year.
SpaceX bought its way past the build versus buy question and acquired a category leader outright, turning Cursor into a wedge against the two companies that have defined enterprise AI adoption.
The deal also signals where Musk intends to deploy his newly public company’s balance sheet. SpaceX now reaches far beyond launch and satellites. With xAI, Colossus, and Cursor, it is assembling a vertically integrated AI stack that spans chips, training infrastructure, frontier models, and the application layer where revenue actually lands.
Questions remain.
Antitrust reviewers will scrutinize a deal that concentrates a leading coding tool inside a company already tied to xAI and Grok. Cursor’s developer base, much of it loyal to a product known for neutrality across models, may bristle at new ownership. Folding a nimble startup into a sprawling aerospace and AI conglomerate carries its own friction.
What is settled is the signal. Agentic coding tools are now strategic assets that command space-program prices, and SpaceX paid up to own one of the best.
