Summary
Reddit, Inc. sued Anthropic PBC on June 4, 2025 in San Francisco Superior Court, alleging Anthropic scraped Reddit user content without authorization to train its Claude large language models, in violation of Reddit's User Agreement. Reddit asserted California state-law claims including breach of contract, unjust enrichment, trespass to chattels, tortious interference, and unfair competition under Cal. Bus. & Prof. Code section 17200. Anthropic removed the case to federal court, arguing the claims were effectively copyright claims subject to exclusive federal jurisdiction. On March 30, 2026 the court rejected that argument and remanded the case to state court, finding the state-law claims contained extra elements beyond copyright infringement. The case remains pending in California state court.
