Sony and Warner name Amodei and Mann personally in their lyrics-piracy suit
Sony Music and Warner Chappell want up to $150,000 for each of thousands, maybe tens of thousands, of songs, and they argue in the filing that the $1.5bn Anthropic already paid was too small to deter anyone valued at $2 trillion.
The Investor · Invest desk

What happened
- Sony Music and Warner Chappell Music have sued Anthropic over allegedly torrented and scraped songs, naming chief executive Dario Amodei and co-founder Benjamin Mann as individual defendants.
- The complaint, filed in federal court in Northern California, points to Library Genesis and the Pirate Library Mirror as acquisition channels and alleges scraping of the licensed lyric sites Musixmatch and LyricFind.
- The publishers seek up to $150,000 for each song found willfully infringed, plus as much as $25,000 for every instance of copyright-management information allegedly stripped from a work.
- The filing argues that $1.5 billion was too small to deter a company it describes as carrying a $2-trillion valuation, a figure it ties to Anthropic's IPO target.
- Anthropic rejects the allegations, calls this the third suit from the same lawyers recycling claims already before the courts, and says it will defend itself robustly.
Why it matters
- Who's exposed exposure Two named humans cannot be reserved against or reorganised the way a balance sheet can, so indemnification and personal counsel now sit inside a negotiation that corporate defendants normally keep entirely at the entity level.
- What it costs cost A ceiling near $3.5bn on a 20,000-work reading is not a verdict, but it is the number a finance function has to hold against, and it is bigger than everything the company has paid out so far.
- What doesn't add up contradiction A June 2025 holding that training is transformative fair use, followed by a $1.5bn settlement in September, leaves buyers unable to tell which half of the pipeline the law actually prices.
The publishers put a ratio inside their own complaint: $1.5bn measured against the $2-trillion IPO valuation they attribute to Anthropic comes to 0.075 percent [15], and the filing says the company "clearly considers that to be just the cost of doing business" [12]. That is a pricing argument dressed as a pleading, and it sets up the ask.
Twenty thousand works at the $150,000 willful-infringement maximum comes to $3bn [16], which is precisely what the same firm asked for in the January suit covering more than 20,000 works [8], and if the separate copyright-management-information count lands at 20,000 instances at $25,000 each you add $500m for a headline ceiling near $3.5bn [17]. Or rather, the more useful version of that arithmetic: 10,000 songs at the statutory maximum is $1.5bn [18], the whole Bartz settlement, from a corpus a tenth the size of the one already litigated. From roughly 500 songs in October 2023 to more than 20,000 in January is a fortyfold increase in claimed works from one law firm [19].
The individual defendants are the new term, and this is probably wrong, but I read Amodei and Mann's names as leverage rather than a theory of liability [1]. A company can be reserved against, insured, and eventually reorganised; a named human sits in depositions, signs discovery responses, and has to ask his own board about indemnification while the company's spokesperson says it will "defend ourselves robustly" [6]. Nothing in the complaint's structure requires the individuals to survive a motion to dismiss for the publishers to get what they want, which is a per-work number.
Anthropic's counter is on the record and it is not weak: this is the third action from the same counsel, recycling allegations already before the courts [6], and Judge Alsup held in June 2025 that training LLMs on copyrighted works was "quintessentially transformative" [10]. The awkward pairing is that the same company settled for $1.5bn three months after that holding [11], which tells you the fair use win covered the training and not the acquisition, and this complaint is mostly about acquisition, alleging Library Genesis, the Pirate Library Mirror, and scraped Musixmatch and LyricFind pages [2], with a secondary claim that Claude reproduces lyrics on the way out [5].
That makes closure by cheque unlikely. Five music suits from three sets of counsel [9], plus the Project Panama book-scanning backlash [14], means every settlement Anthropic signs becomes the opening quote in the next negotiation, and the per-work price implied by $1.5bn stays known only to the people in the room. Anyone negotiating an indemnity cap on a model contract needs that figure; the publishers are litigating to keep it high. If the court drops Amodei and Mann early, my read on executive exposure was wrong and it was always just a settlement tactic.
What to watch
- Whether Amodei and Mann survive a motion to dismiss as individual defendants, which is the test of whether the naming was strategy or substance.
- Any consolidation of the five music suits, which would finally expose a per-work settlement price rather than a total.
- Whether Anthropic's reliance on Alsup's transformative-use holding covers the acquisition claims about Library Genesis and scraped lyric sites.

Sony Music and Warner Chappell Music sued Anthropic, naming CEO Dario Amodei and co-founder Benjamin Mann as individual defendants, over what the suit calls illegal downloading, scraping and torrenting of "thousands upon thousands" of copyrighted songs to train its AI models.
- [2]
The lawsuit, filed in federal court in Northern California, alleges Anthropic obtained lyrics and sheet music through pirate sources including Library Genesis and the Pirate Library Mirror, and scraped licensed lyric websites such as Musixmatch and LyricFind.
- [3]
Sony and Warner seek statutory damages of up to $150,000 for each song the court finds Anthropic to have infringed willfully, and as much as $25,000 for each instance in which copyright-management information was allegedly removed.
- [4]
The complaint covers at least "thousands if not tens of thousands" of works, and potential damages could reach into the billions of dollars.
- [5]
The publishers allege the material was incorporated into Claude's training data and that the model can reproduce copyrighted lyrics in its outputs.
- [6]
Anthropic rejected the allegations, said it will "defend ourselves robustly," and a spokesperson told Fortune "this is the third lawsuit from the same lawyers, recycling allegations from cases already before the courts."
- [7]
Oppenheim and Zebrak, which represents Sony and Warner in the new suit, first sued Anthropic in October 2023 alongside Universal Music Publishing Group, Concord Music Group and ABKCO over roughly 500 songs.
- [8]
The same publishers filed a second suit through the same firm in January, covering more than 20,000 works and seeking over $3 billion.
- [9]
BMG and Round Hill Music have also sued Anthropic over music this year with different counsel, putting the total number of music-copyright suits against the company at five.
- [10]
Anthropic cites Bartz v. Anthropic as fair use precedent, where Judge William Alsup wrote in June 2025 that "the purpose and character of using copyrighted works to train LLMs to generate new text was quintessentially transformative."
- [11]
Anthropic settled in September 2025 for $1.5 billion with the owners of the copyrighted works in that case.
- [12]
The new complaint states that Anthropic "clearly considers that to be just the cost of doing business" and that "$1.5 billion is obviously not a large enough settlement to deter infringing conduct by a company that has parlayed such mass infringement into a staggering $2-trillion-dollar valuation," referencing Anthropic's IPO target.
- [13]
Songs named in the complaint include The Beatles' "I Am the Walrus," Leonard Cohen's "Hallelujah," Mariah Carey's "All I Want for Christmas Is You," Survivor's "Eye of the Tiger," and Taylor Swift's "Cruel Summer."
- [14]
Last month Anthropic faced public backlash over "Project Panama," a plan to "destructively scan all the books in the world" to train its Claude models.
- [15]
The $1.5bn September 2025 settlement equals 0.075 percent of the $2-trillion valuation the complaint attributes to Anthropic's IPO target.
- [16]
Twenty thousand works at the $150,000 willful-infringement maximum produces a $3bn ceiling, the same figure sought in the January suit covering more than 20,000 works.
- [17]
Adding 20,000 copyright-management-information removals at $25,000 each contributes $500m, taking a 20,000-work statutory ceiling to roughly $3.5bn.
- [18]
Ten thousand songs at the $150,000 statutory maximum equals $1.5bn, the same total as the September 2025 settlement.
- [19]
Claimed works from the same law firm grew fortyfold, from roughly 500 songs in October 2023 to more than 20,000 in January.
