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

Sony Music Publishing and Warner Chappell have joined a multi-billion-dollar lawsuit against Anthropic, accusing the AI company of engaging in a 'brazen campaign' of intellectual property theft. The lawsuit, filed in the U.S. District Court for the Northern District of California, alleges that Anthropic used thousands of copyrighted works to train its AI model Claude through illegal methods such as torrenting, scraping, and downloading. Anthropic has denied the allegations and stated it intends to defend itself vigorously. This follows previous lawsuits against Anthropic, including a landmark case where the company was ordered to pay $1.5 billion for alleged copyright violations. The new suit expands accusations to include 'flagrant piracy' involving millions of copies of books containing lyrics and sheet music.

Late Friday night, several major music publishers launched a high-stakes legal battle against Anthropic, accusing the artificial intelligence firm of "one of the largest and most blatant ongoing thefts of intellectual property in history." The lawsuit, filed in federal court in Northern California, names Anthropic, its CEO Dario Amodei, and co-founder Benjamin Mann as defendants. According to the 48-page complaint, the publishers allege that Anthropic systematically downloaded, scraped, and torrented thousands of copyrighted musical works to fuel the development of its AI models, including the Claude series. The plaintiffs are seeking substantial monetary damages, with claims for hundreds of thousands of dollars per infringed piece of music. The lawsuit marks a pivotal moment in the evolving conflict between the music industry and tech companies utilizing AI to train their systems. It follows a broader trend of legal disputes involving AI firms and content creators, raising questions about how intellectual property rights will be enforced in an age dominated by machine learning and data harvesting. The case has drawn attention due to its potential implications for future AI training practices and the protection of creative works in digital spaces. The suit was filed by units of Sony Music and Warner Music, two of the largest players in the global music industry. These entities argue that Anthropic’s actions constitute widespread copyright infringement, enabling the company to generate significant revenue through its AI models while failing to compensate the original creators. The complaint outlines specific allegations, stating that Anthropic engaged in a “brazen campaign” of unauthorized downloads and data collection to build its AI capabilities. The plaintiffs further assert that this behavior has continued unabated, despite previous legal challenges. This is not the first time Anthropic has faced accusations related to copyright violations. In September 2025, the company reached a landmark settlement worth $1.5 billion with authors and publishers, marking the largest copyright agreement in U.S. history. However, the current lawsuit suggests that such issues persist within the company’s operations, particularly concerning the use of copyrighted music in AI model training. The music industry has long been known for its aggressive stance on copyright enforcement, especially during the rise of file-sharing platforms like Napster and LimeWire in the early 2000s. Anthropic did not immediately respond to requests for comment on the lawsuit. Legal experts suggest that the case could set a precedent for how courts handle similar disputes in the future. Given the complexity of AI training processes and the vast amounts of data required, determining liability and appropriate compensation remains a challenging task for both sides. The outcome of this litigation may influence how other AI developers approach data sourcing and intellectual property compliance. The lawsuit underscores growing tensions between traditional media industries and emerging technologies. As AI continues to advance, so too does the need for clear legal frameworks governing the use of copyrighted material. Industry representatives have called for more robust protections for creators, while tech companies often emphasize the necessity of large-scale data access for innovation. This case could serve as a catalyst for policy discussions aimed at balancing these competing interests. As the legal proceedings unfold, all parties involved are expected to present detailed evidence regarding the scope of alleged copyright violations and the extent of financial harm caused. The case may also draw attention from regulatory bodies and lawmakers considering legislation to address the unique challenges posed by AI and intellectual property law. With the stakes high for both the music industry and Anthropic, the coming months will likely see increased scrutiny and public debate over the intersection of creativity, technology, and legal responsibility.
