TL;DR
Sony Music Publishing and Warner Chappell have sued Anthropic in California over what they describe as one of the largest ongoing intellectual property thefts in history. The claim covers at least 20,000 compositions and names chief executive Dario Amodei and co-founder Benjamin Mann personally. Damages sought run to $150,000 per work.
What is alleged
Anthropic acquired the lyrics through piracy networks, bulk scraping and direct downloads, the publishers say, and then served them back to users who asked for them. Among the compositions named in the filing are “All I Want for Christmas is You”, “Eye of the Tiger”, “Hallelujah” and “Uptown Funk”. Some were reportedly lifted from licensed lyric services such as Musixmatch and LyricFind, others from web-crawl archives.
A second strand of the claim is arguably more dangerous for Anthropic than the copying itself. The publishers allege identifying information was stripped from the works during processing, denying rights holders attribution. That carries its own tariff — $25,000 per removal — and it is harder to defend as incidental.
The figure of 7m pirated book copies cited in the filing comes from the authors’ case Anthropic settled earlier for $1.5bn. Litigants are now building on findings established in previous actions, which is what turns a series of separate suits into a compounding problem. Universal Music Group and Concord have claims outstanding, and this month the German agency GEMA beat the AI music generator Suno in court.
Why it matters here
Britain still has not resolved whether text and data mining for commercial AI training requires a licence. That question sat unanswered through the Data (Use and Access) Act debates and it remains the live one for UK rights holders — as our recent coverage of performers seeking a legal right to their own voice showed. Every settlement reached in a US court sets a commercial benchmark that UK negotiations will be measured against, whatever Parliament eventually legislates.
The composer and campaigner Ed Newton-Rex, quoted in the Guardian’s report, said he was unsurprised that rights holders were acting against a company with this training history.
Looking forward
Timing is the sharpest detail. Anthropic is preparing a listing that could value it near $2tn, and prospective investors will want the copyright exposure quantified rather than pending. The company says it disagrees with the claims and will defend them robustly. A settlement in the mould of the authors’ case would be the fastest route to a clean prospectus, and the publishers will know it.
