Music Publishers Sue Anthropic Alleging Massive Copyright Theft for AI Training
Sony Music Publishing, Warner Chappell Music, and other major music publishers filed a lawsuit against AI company Anthropic on Friday, alleging the firm illegally downloaded and used tens of thousands of copyrighted musical compositions to train its Claude artificial intelligence model. The publishers claim Anthropic used methods including torrenting from piracy sites, web scraping, and mass downloading to obtain songs without permission. They're seeking up to one hundred and fifty thousand dollars in damages per infringed work, potentially totaling billions. This is the latest in a series of copyright suits against Anthropic, following a fifteen hundred billion dollar settlement with authors in twenty twenty five. The case centers on whether acquiring training data through piracy violates copyright law, even if using copyrighted material for AI training might otherwise be permitted. Anthropic says it disagrees with the claims and intends to defend itself in court.

Coverage highlights how Anthropic's valuation has soared to over two trillion dollars while creators receive nothing, and notes the company appears to disregard prior legal warnings and settlement obligations.
