Sony Music and Warner Chappell Sue Anthropic Over Claude Training
The suit leaves Anthropic facing litigation from every major music publisher, following earlier cases brought by UMPG, Concord, ABKCO, BMG, and Round Hill.
Reporting from 1 source: GIGAZINE.
Sony Music Publishing and Warner Chappell Music filed suit against Anthropic in California federal court, alleging the company used tens of thousands of copyrighted songs to train its Claude AI and reproduced them in generated output. The publishers seek up to $150,000 per willfully infringed work and up to $25,000 per instance of removed copyright management information, with potential damages in the billions. The complaint also names CEO Dario Amodei and co-founder Benjamin Mann.
The complaint names specific works, including Mariah Carey's "All I Want for Christmas Is You," Survivor's "Eye of the Tiger," and Taylor Swift's "Paper Rings." The publishers also demand destruction of all infringing copies and an accounting of Claude's training data.
The case follows a 2023 suit by UMPG, Concord, and ABKCO over roughly 500 songs, and a 2026 second suit seeking $3 billion over more than 20,000 works. BMG and Round Hill have filed separately, leaving Anthropic in litigation with all major music publishers.
