As of 2026-10-15, 404 Media reported that advertisers can inject personalized ads into ChatGPT sessions based on users' phone numbers or email addresses. According to the report, this practice allows anyone with basic technical skills to upload personal data and target specific ChatGPT users with advertisements. The article highlights concerns about user privacy and transparency, noting that most users are unaware their personal information could be used for targeted advertising within the platform. Additionally, new research confirms that online ads are being exploited by spyware companies to deliver zero-click malware against unsuspecting targets.
This is pretty normal in the advertising world, but I seriously doubt that when most of ChatGPT’s many, many users see an ad, they realize that might be because someone, somewhere, uploaded their phone number into OpenAI’s systems.
OpenAI's ads targeting is pretty creepy
