Elon Musk’s latest AI maneuver has a distinctly industrial feel to it: no flashy consumer app, no polished keynote moment, just a giant bet on the tools developers use to build software every day.
SpaceX says it has secured the right to acquire Cursor, the fast-rising AI coding startup, in a deal valued at $60 billion later this year. The company says it is already working closely with Cursor to build what it calls “the world’s best coding and knowledge work AI.”
The pitch is ambitious, but the logic is easy to follow. Cursor brings strong product instincts and a growing presence among developers. SpaceX, meanwhile, offers serious compute muscle through its Colossus training supercomputer, which the company describes as having the equivalent of one million H100s. Put those pieces together, and the goal becomes clearer: a tightly integrated AI development platform built to produce more capable, more useful models.
According to SpaceX, the agreement gives it the option to buy Cursor later this year for $60 billion, or to pay $10 billion for the work already done with the startup. Cursor chief executive Michael Truell also weighed in on X, saying he was “excited to partner with the SpaceX team to scale up Composer,” Cursor’s AI model.
On the surface, a space company moving deeper into AI coding may look like an odd detour. In reality, it fits the broader restructuring of Musk’s empire. In February, he merged SpaceX and xAI in a deal valued at $1.25 trillion, creating a combined entity that could go public as soon as this year. If that happens, it would likely be one of the most closely watched listings in the market.
The timing is notable. Cursor is also reportedly in talks to raise $2 billion at a $50 billion valuation, according to CNBC. The round is said to be led by Andreessen Horowitz, with participation from NVIDIA and Thrive Capital. Horowitz and NVIDIA are both backers of xAI, adding another layer of overlap to an increasingly intertwined ecosystem.
Why does this matter beyond Silicon Valley intrigue? Because software development has become one of the most important battlegrounds in AI. Google, Anthropic, and OpenAI already have a strong foothold there through tools such as Antigravity, Claude Code, and Codex. If SpaceX and xAI can fold Cursor into their own stack, they may be able to close the gap faster than expected.
For now, the move reads like a classic Musk playbook: move fast, buy scale, and aim at the biggest prize in the room.
