Judge allows most of Reddits lawsuit against Anthropic to proceed
A judge advanced most of Reddit's data-scraping suit against Anthropic, though two claims need amending.
A San Francisco County Superior Court judge has allowed three of five claims in Reddit's lawsuit against Anthropic to proceed. The ruling, made on September 17 and filed the following day, overrules Anthropic's demurrer, which argued that even if Reddit's allegations are true, they do not constitute valid claims. The judge will allow the claims of breach of contract, interference with contract, and violation of California's unfair competition law to move forward.
Two other claims, unjust enrichment and trespass to chattels, were dismissed, but the judge will give Reddit a chance to refile them by October 16. Reddit alleges that Anthropic illegally scraped user comments from its platform to train its Claude chatbot without permission or consent. The case originated from a complaint filed by Reddit in June 2025.
Anthropic had attempted to argue that Reddit's User Agreement was an unenforceable "browsewrap" agreement, but the judge rejected this claim, citing evidence that Anthropic continued to scrape Reddit's site even after Reddit's CEO publicly denounced the behavior.
