SpaceX to acquire AI coding tool Cursor for $60 billion（約9.6兆円） in all-stock deal, marking the largest venture-backed startup acquisition so far in 2026.

What happened: SpaceX, fresh off a $75 billion（約12兆円） IPO last week, formalized plans to purchase Anysphere (parent company of Cursor) for $60 billion（約9.6兆円） in an all-stock transaction. Cursor, founded four years ago, had raised $3.4 billion（約5400億円） from investors including Andreessen Horowitz, Thrive Capital, Accel, and Coatue, and was valued at roughly $30 billion（約4.8兆円） in November. SpaceX shares jumped around 16% on Tuesday following the announcement.

Why it matters: The acquisition gives SpaceX a foothold into the enterprise software development market, where AI-assisted coding has taken off and led large companies to significantly pare back their reliance on human engineers. Cursor reported $1 billion（約1600億円） in annualized revenue as of November last year. For Cursor's backers, the deal represents an enormous return on investment in just four years.

What to watch: M&A activity involving venture-backed startups remains robust in 2026—through June 16, at least 1,177 such deals valued at $182.7 billion（約29兆円） have been announced, compared with 1,132 deals valued at $106.7 billion（約17兆円） in the same period last year. This acquisition underscores SpaceX's expansion beyond space exploration into an umbrella company for CEO Elon Musk's other interests, which already include the social media platform X and AI company xAI.
