Anthropic AI Settlement: Per-Book Payouts, Schedule, and Deadlines

The Anthropic AI settlement is a $1.5 billion class action deal in Bartz v. Anthropic PBC that resolves claims the company downloaded hundreds of thousands of copyrighted books from pirate sites to train its Claude models. Preliminarily approved on September 25, 2025, by the U.S. District Court for the Northern District of California, it pays roughly $3,000 per eligible work to authors and publishers whose books appear on the settlement list.¹ A final fairness hearing was held on May 14, 2026, and payouts are expected once the court issues final approval.²

It is the largest public copyright settlement in American history.

Who Gets Paid

The certified class covers 482,460 specific works downloaded by Anthropic from Library Genesis (LibGen) and the Pirate Library Mirror (PiLiMi).³ To qualify, a book needs an ISBN or ASIN and had to be registered with the U.S. Copyright Office within five years of publication, either before Anthropic’s download date of August 10, 2022, or within three months of first publication.⁴

Both U.S. and international rightsholders can claim, provided their works meet the registration criteria. Works pulled from a separate dataset called Books3 are not covered because they lacked the metadata needed to identify them. Anthropic employees, federal agency personnel, and district court staff are excluded.⁴

How Much Each Book Pays

The gross payout is approximately $3,000 per eligible work before deductions for administration costs and attorneys’ fees. Some reporting has estimated actual per-work amounts closer to $3,100 depending on the final claim count and interest earned.⁵ If the final works list exceeds 500,000 titles, Anthropic pays an additional $3,000 for each extra title.¹

How that $3,000 is divided depends on who holds the rights:

Self-published authors, or authors whose rights have fully reverted, keep 100% of the award for their title.
For trade and university press titles, the default split is 50/50 between author and publisher, though claimants can indicate a different arrangement based on their contracts.
For educational and textbook titles, there is no default; the split follows the individual contract.
If an author and publisher cannot agree, a special master resolves the dispute.⁶

Payment Schedule

Anthropic is paying the $1.5 billion plus interest in four installments:

$300 million by October 2, 2025
$300 million within a week of final approval
$450 million by September 25, 2026
$450 million by September 25, 2027⁶

Distribution to claimants depends on final approval from the court and resolution of any appeals.⁷

Deadlines Have Passed

Claims were administered by JND Legal Administration through AnthropicCopyrightSettlement.com and by mail. Class members had to file individually; publishers could not submit claims on their authors’ behalf.⁸ All primary deadlines are now closed:

Opt-out and objection deadline: February 9, 2026
Re-inclusion deadline: March 9, 2026
Claim form deadline: March 30, 2026⁹

The opt-in rate reached 92.77%, with 447,576 works claimed out of the eligible pool.¹⁰

Where the Case Stands Now

Judge William Alsup, who handled the case through preliminary approval, took inactive status. The case was randomly reassigned to Judge Araceli Martínez-Olguín.¹¹

Judge Martínez-Olguín held the final fairness hearing on May 14, 2026. The 75-minute proceeding drew only seven objectors and passed without significant challenge. The judge did not rule from the bench. She ordered Anthropic to file a supplemental brief by May 21, 2026, addressing why late opt-outs should not be honored, and indicated she would not require further submissions from objectors.² As of mid-2026, final approval has not yet been granted, though observers expect it.⁷

What the Settlement Does Not Cover

The release runs only to past conduct through August 25, 2025. It does not give Anthropic a license for future AI training, does not cover claims tied to AI model outputs, and does not release claims for books that are not on the settlement works list. Authors keep all legal rights for works outside the list.¹

Anthropic must also destroy all original files and copies of the works it downloaded from LibGen and PiLiMi within 30 days of final judgment and certify the destruction to class counsel.¹

Why Anthropic Paid

On June 23, 2025, Judge Alsup ruled that Anthropic’s downloading and retention of pirated books from LibGen and PiLiMi was not fair use. He wrote that pirated copies were “inherently, irredeemably infringing” and that building a permanent research library from stolen files “was its own use — and not a transformative one.” He added that there is “no carveout from the Copyright Act for AI companies.”¹²

That ruling exposed Anthropic to statutory damages of up to $150,000 per willfully infringed work across hundreds of thousands of titles, with potential liability in the tens of billions.¹³ With trial set for December 2025, the company settled. Separately, Judge Alsup had found that training Claude on copyrighted books was “quintessentially transformative” and protected by fair use, but that ruling applied only to the three named plaintiffs, not to the class.¹²

The ClaimsHero Warning

If you were solicited to opt out of the settlement, be aware of what one court called a fraud. ClaimsHero Holdings LLC, an Arizona firm, ran online ads telling authors they could pursue “up to $150,000 per book” outside the settlement. Its “Start Claim” button actually authorized ClaimsHero to opt the author out entirely.¹⁴

At a November 13, 2025 hearing, Judge Alsup called the scheme “a fraud of immense proportions” and labeled the firm’s strategy of aggregating opt-outs “extortion.” He ordered ClaimsHero to update its website within 48 hours to disclose that it had zero federal or state litigation experience and threatened a referral to the U.S. Attorney.¹⁵ The Authors Guild has noted that firms soliciting opt-outs typically charge 30% to 35% contingency fees plus expenses that “can total a million dollars or more,” and that the statutory maximum of $150,000 per work is “rarely awarded.”¹⁶

One high-profile opt-out was investigative journalist John Carreyrou, who filed a separate copyright lawsuit in December 2025 against Anthropic and several other AI companies seeking $150,000 per work per defendant. As of June 2026, claims against Google, xAI, Perplexity, Apple, and NVIDIA in that action have been dismissed, and only the Anthropic portion remains active before the original judge.¹⁷¹⁸

The Author Groups’ Take

The Authors Guild called the $3,000 per-book figure “paltry in light of the gross theft” but urged authors to participate rather than opt out, describing separate litigation as “risky, lengthy, and burdensome.” The Guild noted that discovery alone could delay a decision until at least 2027 and that it was “highly unlikely” Anthropic would settle individual cases for more than the class amount.¹⁶ In a separate FAQ, the Guild framed the deal as a “powerful signal to the industry that piracy is costly” and a “strong payout” that avoids the unpredictability of trial.¹⁹

What It Means Beyond This Case

The settlement resolves whether Anthropic owes compensation for stealing books; it does not decide whether training AI on copyrighted material is itself infringement. That broader question remains legally unsettled for anyone beyond the three named plaintiffs.¹

Still, the $3,000-per-work figure is four times the statutory minimum of $750 and 15 times the “innocent infringement” floor of $200, and plaintiffs in other AI cases are already citing it as a settlement baseline. Plaintiffs in newer suits, including In Re Mosaic LLM Litigation, have adopted the Bartz strategy of targeting piracy specifically rather than AI training in general.²⁰ Whether that approach produces similar results against companies with different facts remains open. For now, Anthropic’s $1.5 billion payout stands as the clearest price any AI company has paid for pirated training data.
