A group of major music publishers led by Concord Music Group and Universal Music Group has filed a new copyright lawsuit against Anthropic, alleging the company illegally downloaded more than 20,000 copyrighted works to train its AI models. The publishers said the claimed damages could exceed $3 billion, potentially making it one of the largest non-class-action copyright cases in U.S. history.
The suit follows revelations from discovery in the earlier Bartz v. Anthropic case, where a federal court ruled that training AI on copyrighted material can be lawful, but acquiring that material through piracy is not. The new complaint names Anthropic CEO Dario Amodei and co-founder Benjamin Mann as defendants. Anthropic has not commented on the filing.
