SpaceX has formally agreed to acquire Anysphere, the parent company of the AI coding assistant Cursor, in a $60 billion all-share transaction that comes just days after the rocket maker’s historic initial public offering. In a filing with the US Securities and Exchange Commission, SpaceX confirmed it will exercise an option secured in April, when the two companies first announced a partnership on computing infrastructure and AI model training. Under the terms, Cursor’s investors will receive SpaceX stock based on the $60 billion valuation, and the start-up will operate as a wholly owned subsidiary once the deal closes, which is expected in the third quarter of 2026. The agreement includes a $10 billion break fee if SpaceX walks away, rising to $14 billion should regulators block the merger on antitrust grounds.

Viewed from Washington, the acquisition underscores the velocity of Musk’s post-IPO ambitions. The Nasdaq listing raised $85.7 billion, catapulting SpaceX’s market capitalisation past $2 trillion and, by some estimates, as high as $2.5 trillion, while propelling Musk’s personal fortune above $1.3 trillion. Cursor, founded in San Francisco in 2022, has rapidly become a favourite among developers, generating roughly $2.6 billion in annual recurring revenue by automating code writing in competition with tools from Microsoft and Amazon. Swedish media highlight that one of Cursor’s co-founders is Arvid Lunnemark, a Swedish national, adding a Nordic dimension to a deal that has drawn attention from Moscow to Buenos Aires.

Russian business dailies note that the acquisition had been telegraphed since April, when SpaceX reserved the right to either buy Cursor outright for $60 billion or pay $10 billion for the joint work. The delay in exercising the option was linked to the IPO process. In the intervening months, two senior product leaders from Cursor joined SpaceX to work on lunar projects and AI development, while engineers from Musk’s xAI venture collaborated with Cursor on coding and data processing. The integration is expected to strengthen xAI’s position in AI-assisted programming, a field where Musk has openly sought to challenge established players.

Analysts in London see the move as a logical extension of Musk’s strategy to weave AI through his industrial empire, from rockets and satellites to social media and now developer tools. By absorbing Cursor, SpaceX gains a direct foothold in the enterprise software market, leveraging the coding agent’s rapid adoption to cross-sell into corporate clients. Yet the deal is not without risk: the antitrust penalty clause signals awareness that regulators in Washington and Brussels may scrutinise the concentration of AI assets under Musk’s control. With closing not expected until the third quarter of 2026, the transaction will remain a bellwether for how far a newly public SpaceX can stretch its remit beyond the launch pad.
