SpaceX has closed its $60 billion acquisition of the AI coding startup Cursor on Friday. The companies first partnered in April, giving Elon Musk’s company the right to buy Cursor. SpaceX committed to the acquisition in June.
“Cursor is now part of @SpaceX,” Cursor said in an X post. “Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world’s most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more. SpaceX has built some of the most inspiring and impressive technology in the world, and we’re grateful for the opportunity to become part of such a special company. Onwards.” Musk responded to this saying, “Welcome.”

According to Business Insider, Cursor trained Grok 4.5 jointly with SpaceX which included using “trillions of tokens of Cursor data,” the AI coding company said. It was the first model Cursor built that wasn’t only for software engineering.
“It’s been a pleasure working with the SpaceXAI team on it,” Cursor cofounder Aman Sanger said on X in July. The company also helped train Grok 4.6, which SpaceX released on Wednesday.
Morgan Stanley estimates that Cursor could add about $2.5 billion to SpaceX’s revenue in 2026 and $13 billion in 2027, according to Yahoo Finance. The analysts said the acquisition could support a much more bullish valuation case for SpaceX if the coding platform continues its rapid growth.
Cursor has emerged as one of the leading AI-powered coding platforms, competing with products from companies including Anthropic and OpenAI. According to media reports, the acquisition gives SpaceX a stronger position in enterprise AI software while providing Cursor access to the computing infrastructure of Musk’s companies.

Cursor said that with SpaceX it is prepared to push its ambitions further. “We will have access to the largest fleet of GPUs in the world, giving us the compute to build stronger models that are also more economical to run,” the company said.
“This means we can provide customers with more capable models at lower cost. Grok 4.6, which we released Wednesday, provides an early look at what we can now build together. SpaceX is building the computing capacity needed to scale intelligence far beyond what exists today. Cursor will be one place where that intelligence becomes useful,” the company added. “For us, that opens a much larger horizon than the one we started with, while keeping the work familiar. We still want to help people with ambitious ideas spend less time writing code and more time solving harder problems. “
