Cursor probed whether employee Grok use exposed client data to SpaceX

An internal investigation at the AI coding platform reportedly began weeks before SpaceX closed its $60 billion acquisition Cursor, the AI coding platform, investigated whether its own employees may have sent confidential client data into SpaceX’s AI systems while testing Grok. The timing is awkward. The probe reportedly started in late July 2026, just weeks before SpaceX finalized its $60 billion acquisition of Cursor on August 14, 2026. The probe began after engineers raised concerns on Slack. They were worried about how confidential client data was being handled during pre-launch testing of the Grok Bot. At the center of those warnings was an internal tool called Sand . Employees flagged the risk that Sand might have inadvertently routed sensitive information to SpaceX’s AI division for use in model training.
