Cursor has officially been acquired by SpaceX, completing a process that began in April when the companies announced a partnership to accelerate model training. The AI coding assistant, founded as Anysphere, will now operate with access to what SpaceX describes as the largest GPU fleet in the world.
The acquisition was announced Thursday alongside the release of Grok 4.6, the latest model from SpaceX's AI division, which the Cursor team says provides an early look at what the combined organization can build. Grok 4.6 is available immediately in Cursor and Grok Build, with API access priced at $2 per million input tokens and $6 per million output tokens.
What's new
- Cursor is now a wholly owned subsidiary of SpaceX.
- Grok 4.6 launches with a focus on long-running agents, interactive work, and visual projects.
- Benchmark claims: matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index (composite of nine benchmarks); 69.9% on CursorBench v3.2; 65.9% on DeepSWE v1.1; 61.3% on FrontierCode v1.1.
- Training included longer supplemental runs, curated model-generated data for reasoning and engineering, and expanded agentic RL across kernel optimization, web development, and CAD domains.
- 2x included usage in Cursor and Grok Build for the first week.
The combined team will use SpaceX's compute capacity to build stronger models that are also more economical to run, aiming to provide customers with more capable models at lower cost. The company emphasized that its mission remains helping developers spend less time writing code and more time solving harder problems.
Why it matters
The deal gives SpaceX a mature AI coding product and distribution channel — Cursor's IDE, enterprise customers, and agent framework — while Cursor gains the compute scale needed to train frontier models without relying on third-party cloud providers. Grok 4.6's benchmark parity with GPT-5.6 Sol on the AA Intelligence Index suggests the combined training pipeline is already producing competitive results.
The acquisition value is reported at $60 billion, though neither company has confirmed the figure. Active collaboration areas include shared model training on SpaceX's Colossus supercomputer cluster, Cursor integration into SpaceX engineering workflows, and joint go-to-market efforts for enterprise customers.
Our take
The speed from April partnership to August acquisition and a joint model release signals unusually tight execution. The real test will be whether Cursor can maintain its product velocity and developer trust while integrating into SpaceX's hardware-first culture — and whether Grok 4.6's benchmark scores translate to day-to-day coding reliability.
