SpaceX completes its $60 billion all-stock acquisition of Cursor maker Anysphere

The most popular AI code editor now belongs to Elon Musk’s rocket company. SpaceX completed its $60 billion acquisition of Anysphere, the company behind Cursor, on August 14, 2026.

The terms

The deal is all-stock: an SEC filing shows Cursor’s outstanding shares converting into roughly 389 million SpaceX shares, with Cursor becoming a wholly owned unit of the new SpaceXAI division. Both companies say no startup has ever been bought for more.

The path was short. The relationship began in April as a partnership to speed up Cursor’s model training. Four months later, the partnership turned out to be a courtship.

What each side gets

Cursor gains access to Colossus, the 200,000-GPU supercomputer, for model training. SpaceX gets the dominant AI coding product on the market, and Cursor’s team will now also work on improving Grok and related products, including Grok Build, Grok Bot and the Grok API.

The open questions

For the millions of developers who work inside Cursor daily, the acquisition raises questions the announcement does not answer. Whether the editor stays model-agnostic is the largest one: Cursor’s value has rested on letting users pick frontier models from any lab, and its new owner ships a competing model family. Pricing under a new owner is the second. How much usage telemetry now flows into the broader Musk ecosystem is the third.

None of that is resolved yet. What is resolved is the market structure: the most widely used AI coding interface is no longer a neutral layer between developers and model vendors.
