Music publishers Sony Music Publishing and Warner Chappell have launched a multibillion‑dollar legal battle against the AI startup Anthropic, accusing it of illegally harvesting tens of thousands of copyrighted songs to train its Claude family of models. The complaint, filed in a California court on 28 August 2026, claims the company scraped lyrics from hits such as Mariah Carey’s All I Want For Christmas Is You, Ain’t No Mountain High Enough and Survivor’s Eye of the Tiger, among many others. The publishers say the conduct amounts to “one of the largest and most blatant ongoing thefts of intellectual property in history”.
The Claims Against Anthropic
The lawsuit alleges that Anthropic’s chief executive Dario Amodei and co‑founder Benjamin Mann orchestrated a systematic effort to download, scrape and reproduce copyrighted lyrics without paying licences. According to the filing, the defendants obtained at least seven million copies of books from pirate sites, extracting lyrics and sheet music for tracks including Bon Jovi’s *Livin’ on a Prayer* and Leonard Cohen’s Hallelujah. The plaintiffs also say Anthropic harvested lyrics from legitimate services such as Musixmatch and LyricFind, and from open archives like Common Crawl, then stripped identifying information to deny creators proper attribution.
Damands and Legal Basis
Sony Music Publishing and Warner Chappell are seeking damages that could run into billions of dollars, basing their claim on a statutory maximum of $150,000 for each infringed work and $25,000 for every removal or alteration of identifying data. The suit references the unlawful copying of “tens of thousands” of musical compositions, implying at least 20,000 songs are involved. The filing notes a parallel settlement in which Anthropic paid $1.5 billion to authors over a similar copyright dispute, using that figure as a benchmark for the current demand.
Industry Reaction and Anthropic’s Stance
Ed Newton‑Rex, a UK‑based composer and copyright advocate, said he was “not surprised” that rights holders were defending themselves against a company with a “history of downloading and training their AI models on huge libraries”. Anthropic has also faced separate claims from Universal Music Group and Concord Music Group. Meanwhile, the music generator Suno lost a copyright infringement case brought by German licensing agency GEMA, which alleged illegal use of tracks such as Boney M’s Daddy Cool to train its technology. Anthropic, which is preparing for a stockmarket listing that could value the company at £2 trillion, told TechCrunch: “We disagree with the publishers’ claims and we intend to defend ourselves robustly in court.”
Why it Matters
This case could set a precedent for how generative technology firms source creative content, potentially reshaping licensing practices across the music, publishing and tech sectors. A ruling in favour of the publishers might force AI developers to negotiate formal licences or face staggering financial penalties, while a decision for Anthropic could encourage broader scraping of copyrighted material under the guise of model training. Either outcome will have far‑reaching implications for artists’ rights, the value of intellectual property, and the future direction of AI‑driven creativity.
