SpaceX exercises $60B option to acquire Cursor, AI coding startup, in largest VC-backed M&A deal ever
SpaceX announced on June 16 that it is acquiring Cursor (developed by Anysphere) for $60 billion in an all-stock transaction, completing what is widely described as the largest acquisition of a venture-backed startup ever. The deal is expected to close in Q3 2026. SpaceX exercised an option it secured in April, when the companies announced a partnership under which Musk's company could either buy Cursor for $60 billion or pay $10 billion to collaborate.
Cursor has grown explosively since its 2022 founding, crossing $1 billion in annualized revenue in late 2025 and reaching roughly $2.6 billion in B2B enterprise revenue and $4 billion in total annualized recurring revenue by June 2026. The tool is used by over half of Fortune 500 companies for code generation, debugging, and editing. SpaceX is paying roughly 15 times revenue—one of the largest multiples ever for an AI software company. The acquisition gives SpaceX, fresh off a blockbuster IPO that raised $75 billion, a developer-heavy customer base and a competing foothold against Anthropic and OpenAI in the AI coding space.
Architects building with Cursor should note that independence from hyperscalers and Musk's ecosystem is now gone, which may trigger migration to GitHub Copilot (Microsoft), Gemini Code Assist (Google), or emerging independent tools. For SpaceX's xAI division, the deal merges Cursor's product distribution and install base with access to Colossus, xAI's Memphis data center complex, accelerating model scaling. This signals that capital structure—IPO liquidity and stock-for-stock deals—now determines outcome in the AI developer tools race as much as product differentiation.
