Filing: Anthropic has agreed to pay $1.5B plus interest to resolve an authors' copyright lawsuit over the company's downloading of millions of pirated books

Anthropic PBC will pay at least $1.5 billion plus interest to resolve an authors' copyright lawsuit over the AI company's downloading …

Bloomberg 2025-09-07

Context & Ripple Effects

The agreement follows an earlier settlement disclosure in the authors’ class action involving works drawn from two pirate databases. It puts the acquisition of training material—not merely the output of AI systems—at the center of the commercial and legal risk.

Later coverage shows the deal moved through judicial review, including preliminary approval of the proposed settlement, underscoring that class-wide resolution remains a process rather than an instant endpoint.

First-order effects

Anthropic takes on a minimum $1.5 billion payment obligation plus interest in exchange for resolving the authors’ lawsuit over the downloaded books.
Affected authors gain a proposed class-wide path to compensation, while the dispute shifts from litigation over the alleged downloading to settlement administration and court review.

Second-order effects

Other AI developers using large, poorly documented text collections will have stronger incentives to audit data provenance and quarantine material obtained from unauthorized sources.
Authors, publishers, and other rightsholders gain a concrete benchmark for negotiating claims tied to the sourcing of AI training data, even though a settlement does not establish a merits ruling.

Third-order effects

If similar disputes continue, provenance controls and rights-cleared data are likely to become a more material operating cost and procurement requirement for frontier-model development.
The case may accelerate a split between companies able to secure and document content rights and those exposed to legacy-data litigation; the eventual legal boundaries remain uncertain without merits decisions.

The trend: This is part of AI content commercialization moving from broad fair-use arguments toward costly, source-specific accountability for training-data acquisition.

The terms of Anthropic's settlement w/book authors just came out. 💰$1.5B to authors in libgen (Books3 corpus)! Interestingly, this is ~$3k per book, close to the terms that HarperCollins allegedly gave to authors for their books ($2.5k). Consensus price forming? [image]

Anthropic class action settlement for using torrented copyrighted downloads for model training $1.5 billion (!) Over double the statutory amount if they had lost the case in jury trial 🤔 < 1% of their valuation which is maybe why they settled 🤷🏾 https://storage.courtlistener.com/…

Lawyers would get 25% cut. A $400 million payday ain't bad. Distribution and opt-outs will be interesting. Apparently, the deal cancels upon a certain (sealed) opt-out threshold.

Quick rundown for non-US academics of whether you're likely to be eligible for the Anthropic payout: — 1. you have works published in or before 2022 — 2. which are registered for US copyright (most likely if you had a US publisher, not otherwise): check here publicrecords.cop…

My understanding is that a separate judge has ruled that training an LLM on legally purchased copyrighted work is transformative enough to be considered fair use. This settlement is exclusively about their use of piracy. www.theverge.com/anthropic/77...

The bad news is that this still turned on a technicality. — These companies can still train on copyrighted work without permission, as long as they get them from a legal source. — So still, little legal protection for creatives whose work is stolen. — apnews.com/article/ant…

Busy yesterday so I missed that Anthropic had settled. Figures. LLMs have violated thousands of copyrights; they *knew* it would kill them if it went to trial. Anyway, the Authors Guild has some useful info here: authorsguild.org/news/what-au...

i basically agree with the transformative use argument (and think the implications of it not being considered transformative use would have disastrous implications for libraries, accessibility programs, etc.) but the last line of this is just so goofy and stupid. — www.nytimes.…

You win some and you lose some. While Anthropic won the copyright case based on training their AI from copies of books they bought, they've just settled a case based on training AI on pirated books. — The settlement is for $1.5B which works out to about $3,000 per book.
@stinasdemons.com @stinasdemons.com on bluesky
$3,000 for each copyrighted work that Anthopic pirated. The class action settlement will apply to approximately 500,000 works. I think the real number is much higher. And don't get me started on all the artists' work “AI” has stolen...

For anyone who thinks that is a lot of money consider that their last round of funding was for 13B, and that normally big copyright infringement costs like 150k per, not the 3k per they are gonna pay. A fine is a price. For 1/10th of their funding they will keep and use this da…

Really interesting decision here ... worth underscoring (as Kate does in the article) that contrary to the rhetoric of the plaintiffs' attorney the decision has to do with piracy, not AI training. [embedded post]
@kalihays Kali Hays on bluesky
Largest settlement in all of copyright litigation, and yet, $3k to each author that had the work stolen for for profit use seems so incredibly small. And the judge sided with Anthropic on fair use, finding that the training itself was transformative. Idk if this even counts as …
