Platform accuses chatbot developer of breaching its terms and unfairly profiting from user-generated content.
Reddit has filed a lawsuit against the AI firm Anthropic, accusing it of illegally scraping user comments to train its chatbot, Claude. The case, brought in California Superior Court, opens a new front in the growing legal battle against AI firms accused of harvesting online data without consent.
According to the filing, Anthropic used automated bots to extract Reddit content in breach of the platform’s terms of use. Reddit’s chief legal officer, Ben Lee, said AI developers must be held accountable for how they gather and use data. “AI companies should not be allowed to scrape information and content from people without clear limitations on how they can use that data,” he said.
The lawsuit differs from other recent actions against Anthropic, such as those from music publishers over copyrighted lyrics. Instead, Reddit is arguing breach of contract and unfair competition, claiming that Anthropic benefited commercially by training its models on material it had no right to use.
Reddit has previously signed licensing deals with companies including Google and OpenAI. These agreements come with safeguards that give users some control over how their content is handled and protect them from unsolicited contact. With a public listing on the horizon, Reddit is keen to assert its role not just as a content platform but as a steward of user trust.
Anthropic, founded by former OpenAI executives, says it uses public data in line with legal norms and has described its training methods as statistical rather than extractive. But Reddit claims the company scraped its site more than 100,000 times – even as it claimed to block bots – and that this data collection was systematic and unauthorised.
The case arrives amid wider scrutiny of how AI companies acquire the material that powers their tools. As large language models become more embedded in everyday life, content creators and platforms are pushing back against what they see as unlicensed appropriation of their work. Anthropic is already facing other lawsuits over the use of copyrighted material.
The outcome of Reddit’s action could set important legal precedents, especially as regulators begin to examine the intersection of user rights, intellectual property and artificial intelligence. The stakes are high, not just for Reddit and Anthropic, but for any company that relies on user-generated content or trains models on publicly available data.
