Sony Music, Warner sue Anthropic, alleging a “brazen campaign” of intellectual property theft

What's happening

Sony Music Publishing and Warner Chappell sued Anthropic, co-founder Benjamin Mann, and CEO Dario Amodei in US District Court for the Northern District of California, alleging Anthropic trained its Claude models on "tens of thousands" of copyrighted songs using mass torrenting, scraping, and downloading. The publishers seek statutory damages of up to $150,000 per work and up to $25,000 for each instance where identifiable copyright data was stripped. The complaint cites internal Anthropic staff chats praising piracy ("Zlibrary my beloved") and frames the conduct as a "brazen campaign" of intellectual property theft; Anthropic disputes the claims and has said it will defend itself.

Why it's trending

Because the suit ties alleged large-scale torrenting and internal praise of piracy to concrete statutory damages, it raises fresh legal and financial stakes for how music gets used to train models now.
