Music publishers file lawsuit against Anthropic over alleged copyright infringement in AI training
Sony Music and Warner Chappell have sued Anthropic, alleging it used pirated sources to obtain thousands of copyrighted songs for training its Claude AI. The publishers seek statutory damages that could reach billions of dollars. Anthropic has rejected the claims and vowed to fight the lawsuit.
The lawsuit marks the third music-copyright action against Anthropic from the same law firm, following earlier suits over 500 and 20,000-plus songs. Anthropic has previously cited a June 2025 ruling in *Bartz v. Anthropic* as supporting its fair-use defense, though it later settled that case for $1.5 billion. The new complaint names specific tracks, from Marvin Gaye to Taylor Swift, and alleges violations of lyric-site terms.
Anthropic’s broader legal exposure now spans five music suits, including separate actions from BMG and Round Hill. The company’s “Project Panama” book-scanning controversy last month adds to its copyright scrutiny. Publishers argue that even if training is transformative, reproducing lyrics in outputs remains infringing, a distinction courts have yet to fully resolve.
This case could reshape how AI firms source training data, potentially forcing them to license content or face crippling damages. Songwriters and publishers may gain stronger leverage, while AI developers might see higher costs and slower innovation. Consumers could experience restricted AI features or higher subscription prices. The outcome may also influence other creative industries, setting precedents for fair use in generative AI.
