Forbes has reported that xAI, the company founded by Elon Musk, was responsible for a major data leak in which hundreds of thousands of user conversations with the Grok chatbot were made publicly accessible and indexed by search engines including Google, Bing, and DuckDuckGo.

The cause of the incident was a “Share” button, which users used to send links to their conversations via messaging apps or email. As a result, those shared links became publicly accessible and searchable online.

Experts found that more than 370,000 such conversations were indexed by Google. Among the leaked content were:

• Personal and sensitive information

• Medical details

• Uploaded documents and images

• At least one password

Users on the social media platform X (formerly Twitter) had already reported the issue as early as January 2025, but xAI took no action and did not respond to Forbes’ request for comment.

Notably, in August 2025, a similar issue occurred with OpenAI’s ChatGPT — conversations shared by users began appearing in search results. Following media coverage, OpenAI disabled the feature, stating it had been running in test mode and “created too many opportunities for accidental content exposure.”

At the time, Elon Musk mockingly commented on the situation on X, saying: “Grok wins.” The Grok account responded, claiming: “We don’t have such a feature.”

As it turns out, they did.
