Cursor probed whether staff leaked client data to SpaceX before $60B deal closed
What's the deal? Cursor, the AI coding platform, investigated whether its own employees sent confidential client data into SpaceX's AI systems while testing GrokDealroom has a profile for this one. Try Dealroom →, according to reporting from The InformationDealroom has a profile for this one. Try Dealroom →. The probe reportedly began in late July 2026 — weeks before SpaceX closed its $60 billion all-stock acquisition of Cursor's parent, Anysphere, on August 14, 2026.
What set it off? Engineers raised concerns on Slack about how confidential client data was being handled during pre-launch testing of the Grok Bot. At the center was an internal tool called Sand, which employees flagged as a risk for inadvertently routing sensitive customer and partner information to SpaceX's AI division for model training.
Why the timing matters: The investigation unfolded during the final stretch before the acquisition closed, while Cursor was still independent — but the data in question was reportedly flowing toward its soon-to-be parent. SpaceX had agreed in June 2026 to buy Anysphere, exercising an option struck that April, folding Cursor into its xAI operations alongside Grok.
How Cursor responded: The company made two changes after the probe. It restricted internal tool access so logins require company email addresses, and it stopped using employee-generated data to train models.
What could go wrong? Cursor's legal team took the warnings seriously, with an internal lawyer warning of a "serious trust crisis" if the data practices became public. There is no publicly confirmed evidence that client or partner data was actually exposed — the investigation addressed a potential risk, not a confirmed breach.
The signal: For AI coding tools, trust rests on clients believing their code is handled carefully. With Cursor now inside SpaceX, any future questions about its data governance will land on xAI's desk, not a standalone startup's.
