Acquisition Finalized

SpaceX has officially closed its acquisition of Cursor, an AI coding startup. The completion of the deal was announced on Cursor's blog, making the startup a part of Elon Musk's aerospace company.

Background of the Deal

The initial agreement between SpaceX and Cursor was made public in April, outlining a collaboration to develop technology. This deal included an option for SpaceX to acquire Cursor for $60 billion. The acquisition moved forward two months later, coinciding with SpaceX becoming a public company.

Access to Computing Resources

A key aspect of the acquisition for Cursor is gaining access to SpaceX's computing infrastructure. Cursor stated that becoming part of SpaceX provides it with "access to the largest fleet of GPUs in the world." SpaceX's computing resources are also rented out to other companies, including Anthropic and Google.

Strategic Importance for AI Development

SpaceX indicated that it is building the computing capacity necessary to expand intelligence beyond current capabilities. Cursor's role within SpaceX will be to make this intelligence useful, integrating its AI coding expertise with the available computational power.

How outlets covered it

OpenAI has terminated Cursor's direct access to its models, citing past contract violations by Elon Musk's companies, Twitter and xAI, following SpaceX's acquisition of Cursor. In contrast, Anthropic confirmed it will continue to support Cursor as a trusted partner, increasing compute for Claude models within the platform.

OpenAI announced its intention to end its contract providing AI models to Cursor, an AI-powered code editor owned by SpaceX, by November 12, 2026. This decision stems from OpenAI's claim that Elon Musk's companies have violated previous contracts, making them unable to trust SpaceX to adhere to terms of service. The termination impacts developers using OpenAI models via Cursor, who will need to adapt to the change.

OpenAI announced it will end Cursor's access to its models, citing concerns over SpaceX's adherence to terms of service following its acquisition of Cursor. This decision impacts approximately 5% of Cursor's user traffic and reflects ongoing disputes between OpenAI and Elon Musk.

OpenAI will cease providing its models to the AI coding assistant Cursor by November 12, 2026, or earlier, due to Cursor's acquisition by SpaceXAI. OpenAI stated it lacks confidence that SpaceXAI will adhere to its terms of service, citing past experiences with Elon Musk's companies.

SpaceX has officially completed its acquisition of AI coding startup Cursor, following an initial deal announced in April. This acquisition provides Cursor with access to SpaceX's computing infrastructure, including a large fleet of GPUs, to further develop AI capabilities.
