Case overview
What this settlement is about
A new lawsuit filed by plaintiff Jon Woodard accuses OpenAI and Mixpanel of failing to prevent a November 2025 data breach in Mixpanel's systems that allegedly exposed personally identifiable information tied to OpenAI's API platform and certain ChatGPT help-center users. The exposed data reportedly included names, email addresses, approximate locations, operating systems and browsers, referring websites, and organization or user IDs. The complaint raises claims of negligence, breach of implied contract, and unjust enrichment, and seeks declaratory and injunctive relief along with damages on behalf of a proposed nationwide class of people whose personal information was allegedly accessed or acquired by an unauthorized party in the breach. No settlement has been reached; the case is an active lawsuit seeking to establish liability and remedies.
