Sony Music Publishing and Warner Chappell Sue Anthropic Over Copyright

On August 28, 2026, Sony Music Publishing and Warner Chappell Music sued Anthropic in the U.S. District Court for the Northern District of California — and this time they didn't just sue the company. They personally named CEO Dario Amodei and co-founder Benjamin Mann as individual defendants.

What the publishers allege

The complaint accuses Anthropic of large-scale scraping, torrenting, and downloading of copyrighted works to train its Claude models. Sony and Warner Chappell claim Anthropic obtained and used "tens of thousands" of musical compositions without authorization, including works tied to well-known songs such as Eye of the Tiger, September, Uptown Funk, Hallelujah, Taylor Swift's Paper Rings, and Mariah Carey's All I Want for Christmas Is You.

The ask: up to $150,000 per work

The publishers are seeking a jury trial and statutory damages of up to $150,000 per infringed composition — a figure that, multiplied across the "tens of thousands" of works cited in the suit, puts the potential financial exposure in a range that could reach billions of dollars. Anthropic responded that it disagrees with the allegations and intends to defend itself "robustly" in court.

Why naming the founders personally changes the calculus

Naming Amodei and Mann as individual defendants — not just the corporation — is a legal strategy meant to add pressure: in theory, it opens the door to personal liability if it's shown that training-data sourcing decisions were knowingly made or authorized at that level. It's a signal of where generative AI litigation is heading: it's no longer enough for the company to absorb the risk as a cost of doing business — plaintiffs are now also targeting whoever sets the data strategy.

What this means for a company adopting generative AI

If your company integrates a generative AI provider's model into a product, the legal risk of "where did the training data come from" isn't just the provider's problem — it can become your own due-diligence problem if the provider ends up with an adverse ruling that affects service continuity or pricing. It's worth reviewing your AI vendor's indemnification terms (what's covered if a third party sues over generated content) rather than assuming that risk stays entirely outside your company.
