SpaceX Buys Cursor for $60B, Largest Startup Acquisition Ever

SpaceX exercised its option to acquire Cursor, the AI coding startup, for $60 billion in Class A stock—the largest acquisition of a venture-backed startup outside of a self-deal. The deal, announced June 16, four days after SpaceX's record $86.2 billion IPO (which raised $75 billion), is paid entirely in stock and expected to close in Q3 2026. Cursor has reached $2.6 billion in annualized revenue as of June 2026, up from $1 billion in November 2025.

The acquisition costs SpaceX essentially nothing in cash: the stock appreciated from $135 IPO price to $192+ within days, covering the entire deal in stock appreciation alone within the first trading session. Cursor's parent company Anysphere was founded in 2022 and has roughly 4 million active developer users. The deal reflects SpaceX's broader AI ambitions—the company pitched investors on a $28.5 trillion AI-adjacent TAM, with $26 trillion in AI infrastructure and applications. Cursor's product complements SpaceX's Colossus supercomputer and xAI's Grok model.

For teams evaluating AI-powered dev tools, the acquisition raises questions about Cursor's independence and future model partnerships (it currently supports Claude, GPT, Gemini, and local models). The deal exemplifies 2026's pattern of mega-acquirers using appreciated stock as acquisition currency post-IPO, making independent tooling more vulnerable to rollup. Teams should consider whether alternatives like VS Code + Copilot, Windsurf, or direct API access offer more stability.
