SpaceX has officially completed its acquisition of AI coding startup Cursor, finalizing the $60 billion all-stock deal that began with a partnership announcement in April. The integration of Cursor into SpaceX's AI division, SpaceXAI, was confirmed on August 14, marking one of the largest acquisitions in the startup world. The acquisition's completion follows regulatory approvals and the conversion of Cursor's shares into SpaceX Class A common stock.
The Cursor team will now focus on developing SpaceX's Grok AI and related products, including Grok Build, Grok Bot, and the Grok API. This move signals SpaceX's intent to bolster its artificial intelligence capabilities and compete more directly with established AI leaders such as OpenAI and Anthropic. Cursor's primary benefit from the acquisition is access to what it describes as "the world's largest GPU fleet," providing the computing power necessary to build more advanced and cost-effective AI models. This enhanced computational capacity is expected to translate into better AI models at a reduced cost for customers.
The collaboration between SpaceXAI and Cursor has already yielded early results, with the release of Grok 4.6. This latest iteration of the Grok model is presented as a preview of what the combined entities can achieve, demonstrating improvements in coding, agentic tasks, and general knowledge work. Grok 4.6 was trained to perform real-world tasks, including general coding, web development, and computer-aided design. On internal benchmarks, Grok 4.6 High scored 69.9 percent on CursorBench v3.2, with the Extra High variant reaching 70.8 percent. On the Artificial Analysis Intelligence Index, the model achieved a score of 61, matching GPT-5.6 Sol Max.
Cursor, founded in 2022, quickly gained recognition for its AI-powered coding assistant, designed to help programmers write and debug code more efficiently. The company experienced rapid growth, reaching over $1 billion in annualized revenue by November 2025. Prior to the SpaceX acquisition, Cursor had secured significant funding rounds, with its Series D in November 2025 valuing the company at $29.3 billion. Reports from April indicated that SpaceX had the option to acquire Cursor for $60 billion or opt for a partnership alone for $10 billion, with the former option now exercised.
The acquisition also follows Cursor's recent purchase of the team behind Firetiger, an agent builder for software deployment monitoring and incident investigation. This move suggests a broader strategy to integrate AI capabilities across the entire software development lifecycle, from initial coding to post-deployment management.
SpaceX's integration of xAI earlier in the year, now operating as SpaceXAI, signifies a concerted effort to consolidate its AI ambitions. The company is also developing AI satellites and has a facility planned for their large-scale manufacturing. This comprehensive approach aims to establish SpaceX as a significant player in both AI infrastructure and model development.
