SpaceX closes $60B Cursor acquisition, ships Grok 4.6
The deal is done. SpaceX has officially closed its $60 billion acquisition of Cursor, the AI coding tool startup. The companies announced the purchase in June, though the partnership traces back to April when they began working together on Cursor’s model training.
What Cursor Gets
Cursor says the deal gives it access to what it describes as the largest fleet of GPUs in the world. The stated goal is to build and train better models and pass cost savings to customers.
The SpaceXAI Context
SpaceX merged with Elon Musk’s AI company xAI earlier this year. That combined entity officially became SpaceXAI in July. Shortly after, SpaceXAI and Cursor released Grok 4.5, their first jointly built model, designed to excel at coding, agentic tasks, and knowledge work at lower costs. They have since followed up with Grok 4.6, trained on real-world tasks including general coding, web development, and computer-aided design. Cursor describes Grok 4.6 as an early look at what the combined teams can build together.
The Operator Angle
If you use Cursor daily, the pitch is cheaper inference backed by more compute. Whether that translates to lower subscription pricing or just better model performance at the same price remains to be seen. Watch the Grok 4.x release cadence as the clearest signal of how fast this partnership moves.
