SpaceX Stock Jumps 10% on $60B Cursor Deal, Adding $247B in Market Cap

Investors are cheering SpaceX’s latest move: a $60 billion all-stock grab of AI darling Cursor. The deal, revealed Tuesday, propelled the company’s market value up by nearly a quarter-trillion dollars, underscoring Wall Street’s appetite for Musk’s AI-fueled vision and the potential high-margin revenue from enterprise coding tools.

SpaceX’s agreement to acquire Anysphere, the parent company of the AI coding platform Cursor, for $60 billion in an all-stock deal marks one of the largest software transactions of the year and underscores the company’s rapid transformation from aerospace giant to AI-driven conglomerate. The deal, announced on June 16, 2026, just months after SpaceX’s record $85.7 billion initial public offering that valued the company at over $2 trillion, will close in the third quarter of 2026. It represents the culmination of a strategic option disclosed in April, when SpaceX revealed a partnership with Cursor that included the right to purchase the startup for $60 billion—or to opt for a $10 billion collaboration. By exercising the acquisition route, SpaceX is making a decisive bet on the enterprise AI coding market, a space where rivals OpenAI and Anthropic have already staked claims but where Cursor has emerged as a formidable competitor.

SpaceX shares surged nearly 10% in premarket trading following the announcement, adding roughly $247 billion to its market capitalization, which stood at $2.53 trillion.

Cursor’s rapid ascent has been remarkable. Founded in 2022 and launched in 2023, its agentic AI coding tool quickly gained traction among software developers at leading tech firms including OpenAI, Datadog, Nvidia, and Adobe. By the end of 2025, Cursor had surpassed $1 billion in annualized revenue, and recent data shared with Reuters shows its business-to-business revenue has climbed to approximately $2.6 billion on an annualized basis. The startup’s growth, however, has been bottlenecked by access to high-performance computing power. In its April partnership announcement, Cursor explicitly stated that its ambition to advance its Composer agentic model had been constrained by compute, a challenge that the deal with SpaceX’s AI arm, xAI, directly addresses through access to the Colossus supercomputing infrastructure.

The merger of SpaceX and xAI, completed in February 2026, created a combined entity with a vast addressable market estimated at $28.5 trillion, spanning space operations, satellite communications, and artificial intelligence. By bringing Cursor in-house, SpaceX gains a direct revenue stream from the fast-growing developer tools segment while also integrating cutting-edge AI coding capabilities into its own engineering processes. The all-stock structure, which does not touch IPO proceeds, signals confidence in the combined company’s future and avoids immediate cash outlays, an important consideration given the capital-intensive nature of SpaceX’s core businesses like Starship development and Starlink expansion.

Market reaction has been emphatically positive. SpaceX shares surged nearly 10% in premarket trading following the announcement, adding roughly $247 billion to its market capitalization, which stood at $2.53 trillion. At $211.27 per share, the stock has risen more than 56% from its IPO price of $135, and the gains pushed SpaceX’s valuation past Amazon’s to make it the fourth most-valuable U.S. publicly traded company. Investors appear to be pricing in the strategic synergies: Cursor’s enterprise contracts offer high-margin recurring revenue, and the integration with xAI’s infrastructure promises a durable competitive moat in the AI coding assistant sector, where deep-pocketed competitors are also racing to capture enterprise customers.
