Cursor is building 'Sand,' a workplace agent, on SpaceXAI compute

The code-editor company's first non-developer product is in internal testing — but a $60 billion SpaceX buyout may rewrite the roadmap before Sand ships.

Cursor is building a workplace agent, internally codenamed Sand, on compute leased from SpaceXAI, according to a July 9 report in The Information citing two people familiar with the project. Internal rollout to Cursor employees began in late June, and development reportedly started in April, the same month Anysphere, Cursor’s parent, began leasing infrastructure from SpaceXAI.

The timing isn’t incidental. On June 12, SpaceX went public on the Nasdaq; four days later, it signed a definitive $60 billion all-stock agreement to acquire Anysphere, with closing expected in Q3. Sand is thus a product being built inside a company mid-acquisition, on the acquirer’s compute, in a category adjacent to but distinct from the one that made Cursor worth $60 billion in the first place.

That original business is doing fine. The Cursor code editor, forked from Microsoft’s Visual Studio Code, went from roughly $2 billion in annualized revenue in February to roughly $4 billion by early June, per TechTimes, and now sits inside nearly two-thirds of the Fortune 500.

Sand pushes into denser territory. Anthropic first shipped Claude Cowork in January and hit general availability in April; on July 7, it extended Cowork from desktop to mobile and web. Two days later, OpenAI launched ChatGPT Work, powered by GPT-5.6. TechTimes reports that across 1.2 million Cowork sessions, usage skews toward business operations and content work rather than coding, which is precisely the surface Sand would contest.

Cursor’s angle, per TNW and TechTimes, is the Model Context Protocol layer. MCP, the open standard Anthropic published in November 2024, now stitches together Vercel, Cloudflare Workers, GitHub, Sentry, Linear, and Slack, and it’s where Cursor thinks it can out-integrate the incumbents.

Whether Sand survives contact with SpaceX’s roadmap is the more interesting question. Jensen Huang’s Nvidia isn’t in this frame, but every other rocket-adjacent player is. Sand is being built on the buyer’s infrastructure before the buyer takes control.
