Sony Music, Warner sue Anthropic over alleged IP theft
On August 29, 2026, music publishers Sony Music Publishing and Warner Chappell Music filed a joint lawsuit in California federal court against AI startup Anthropic and its co-founders, Dario Amodei and Benjamin Mann. The complaint accuses Anthropic of systematically downloading, scraping, and copying tens of thousands of copyrighted music compositions—including tracks like 'All I Want For Christmas Is You'—from illegal torrent networks such as Libgen and Pilimi to train its Claude AI models. The plaintiffs seek statutory damages of up to $150,000 per willful infringement, which could expose Anthropic to billions of dollars in potential liabilities, alongside the destruction of infringing copies and a listing of Claude's training data. Anthropic denies the allegations and plans to defend itself, while the lawsuit references a prior $1.5 billion authors' dispute and earlier litigation by Universal and BMG.
A major lawsuit by large music publishers against an LLM lab could set legal precedents on data acquisition and training practices for generative AI models, affecting compliance, risk and business models across the AI and media ecosystems.

Anthropic's $1.5B Copyright Settlement Approved
Anthropic reached a court-approved $1.5 billion class-action settlement resolving authors’ claims that its Claude models were trained using pirated books. The fund will compensate affected authors and publishers — roughly 500,000 works are estimated eligible, with proposed payments of about $3,000 per eligible work — and cancels a planned jury trial. Judge Araceli Martinez-Olguin gave final approval after earlier proceedings in which Judge William Alsup found Anthropic had used pirated sources (including piracy sites) but also held that training on copyrighted books can, in some circumstances, be fair use. Because Anthropic settled rather than appeal, the case will not create binding nationwide precedent; related lawsuits against Google, Meta, Midjourney and OpenAI remain active. Participating plaintiff firms are slated to receive over $100 million in fees.
Book Publishers Sue Google Over AI Training
A coalition of major publishers and authors — including Hachette Book Group, Cengage, Elsevier, novelist Scott Turow and S.C.R.I.B.E. — filed a class-action lawsuit against Google on July 14, 2026 in the U.S. District Court for the Southern District of New York. The complaint alleges Google trained its Gemini models on copyrighted books sourced from Google Books and titles uploaded to Google Play without permission, and removed or altered copyright information to conceal that use. Plaintiffs cite internal Google estimates of potential liabilities in the tens to hundreds of billions and say the practice displaces sales and undermines licensing markets. The filing is part of a broader wave of litigation over AI training data and follows publisher tactics such as crawler blocks and threats to delist from search.
