Reddit Sues Anthropic Over Use of Its Unauthorized Data, Here's What Happened

On June 4, 2025, Reddit initiated legal action against AI startup Anthropic in California Superior Court, alleging unauthorized use of Reddit’s user-generated content to train Anthropic’s AI chatbot, Claude. The lawsuit claims that Anthropic’s bots accessed Reddit’s servers over 100,000 times since July 2024, despite the company’s assurances that it had ceased such activities.

Reddit asserts that Anthropic violated its user agreement by scraping content without permission. This resulted in infringement on the platform’s terms that prohibit commercial exploitation of user data without a formal agreement. While Reddit has established licensing deals with companies like OpenAI and Google, Anthropic allegedly refused to enter into a similar agreement.

The complaint highlights that Anthropic’s actions not only breach contractual obligations but also undermine user privacy protections. Reddit emphasizes that its licensing agreements with other companies include provisions to remove deleted posts from AI training datasets, a safeguard absent in Anthropic’s approach.

Anthropic, backed by significant investments from Amazon and Google, has denied the allegations and expressed intent to defend itself vigorously. The company maintains that its training practices are lawful and that it has not violated any agreements.

This lawsuit adds to the growing number of legal challenges AI companies face over data usage practices. Such cases raise concerns about the ethical and legal implications of training AI models on publicly available content without explicit consent.
