Sony, Warner Music Sue Anthropic Over AI Training Copyrights
WMG sits 20% above its 52-week low of $23.34.
Summary
Warner Music and Sony Music have filed a joint lawsuit against Anthropic, alleging the AI company illegally used their copyrighted song lyrics and sheet music to train its Claude models. The complaint, filed Friday in California federal court, claims Anthropic obtained the works via torrent downloads and that Claude can reproduce lyrics verbatim. The publishers seek up to $150,000 per infringed work and an injunction. This follows Warner's earlier acquisition of Sureel AI and a separate AFM lawsuit over music licensing, signaling an aggressive legal stance on AI. The case adds to a wave of copyright litigation against AI firms, including Universal Music's ongoing 2023 suit against Anthropic. A ruling or settlement could set precedent for AI training data rights across the music industry.
