Anthropic’s $1.5 Billion AI Copyright Settlement: Claims and Payouts

Anthropic’s copyright settlement will pay a minimum of $1.5 billion, plus interest, to the owners of roughly 482,000 books the company downloaded from pirate repositories to train its Claude chatbot. After attorneys’ fees and administrative costs, base payouts are projected at about $2,932 per work for claimants who are sole copyright owners, based on the roughly 448,000 works claimed as of March 2026. The deal received preliminary approval in September 2025 and went through its final fairness hearing on May 14, 2026; final approval is pending.

What Anthropic Agreed to Pay

The settlement fund is $1.5 billion at a minimum, paid in four installments. Anthropic paid $300 million by October 2, 2025. Another $300 million is due within a week of final approval. A third payment of $450 million is due by September 25, 2026, and a final $450 million by September 25, 2027.¹ Interest accrues on the fund as it sits.

The money is not the only obligation. Anthropic must destroy all original files and derivative copies obtained from Library Genesis (LibGen) and Pirate Library Mirror (PiLiMi) within 30 days of final judgment.² The settlement does not give the company any license to keep using those books for AI training, and it does not release claims that Claude’s outputs might infringe copyrighted works.³

Which Books Are Covered

The settlement applies only to books that appear on a court-finalized Works List of titles Anthropic pulled from LibGen (in June 2021) and PiLiMi (in July 2022). To land on that list, a book had to meet three conditions:

It has an ISBN or Amazon ASIN.
It was registered with the U.S. Copyright Office within five years of publication.
The registration predates Anthropic’s download, or falls within three months of publication.

About 482,000 works met those requirements.⁴² Foreign works without U.S. registration are outside the class, an exclusion raised by objectors at the fairness hearing.⁵

Who Can Claim and How Payments Split

Eligible claimants include individual authors, publishers, academic institutions, estates, and trusts. For trade and university press titles, when both an author and a publisher file claims on the same book, the settlement uses a default 50/50 split. Self-published authors, authors whose rights have reverted, and any other sole copyright owner receive the full per-work amount. If co-claimants disagree, a court-appointed special master resolves the dispute.¹

How Much Each Work Will Get

The fund is divided equally across all works with valid claims, so the per-work figure moves with the claims rate. Roughly $1.18 billion is expected to remain after fees and costs. Early in the claims period the projected payouts looked much higher. In October 2025, with fewer than 59,000 works claimed, sole owners were on track for about $20,000 per work. By December 2025 that had dropped to roughly $12,400 as claims covered about 95,000 works.⁶

By March 2026, with a 93% claims rate and roughly 448,000 works claimed, the Authors Guild estimated a base payout of about $2,932 per work before interest.⁷ Where the default 50/50 split applies, an author sharing with a publisher would receive roughly half that per title. The final figure could shift slightly depending on the court’s ruling on fees and on interest accrued on the fund.

Deadlines and Where to File

The settlement is administered by JND Legal Administration at anthropiccopyrightsettlement.com. Claimants had to search the Works List, confirm ownership, and submit a claim form indicating ownership status and preferred split.⁸ The claims deadline was March 30, 2026.¹

The deadline to opt out or object was January 29, 2026, extended from an original date of January 14. By the fairness hearing, the final count was 350 opt-outs and 53 objections against about 448,000 works claimed, described by lead counsel as a 92.77% opt-in rate.²⁹ Anthropic has asked the court to deny five late opt-out requests on the ground that the objectors did not show excusable neglect.¹⁰

What the Settlement Does Not Cover

Three limits matter for anyone reading this as a rights holder. First, only books on the Works List are in the class; other titles Anthropic may have used through lawful channels are not part of this deal. Second, Anthropic gets no license going forward. Third, if Claude generates output that infringes a copyrighted work, claims about that output are not released by this settlement.³

The settlement also does not resolve the broader question of whether training AI on lawfully acquired copyrighted books is fair use. Judge William Alsup ruled in June 2025 that using purchased books to train Claude was “exceedingly transformative” and qualified as fair use, but denied summary judgment on the piracy claims, holding that there is no “get out of jail free card” for using stolen copies.¹¹¹² The piracy piece is what this settlement pays for.

Where the Case Stands Now

Judge Alsup, who ran the case on a fast track after it was filed in August 2024, retired at the end of 2025. Judge Araceli Martínez-Olguín took over and presided at the May 14, 2026 fairness hearing. Seven objectors argued for 75 minutes, raising notice adequacy, the foreign-works exclusion, treatment of pseudonymous authors, and whether $3,000 per work is fair given statutory damages of up to $150,000. The judge did not rule from the bench and ordered Anthropic to file a supplemental brief on the late opt-out requests by May 21.⁵

Attorneys’ fees are still being litigated in a way that could nudge the per-work number. Class counsel initially sought $300 million, including $75 million for three “coordination counsel” firms. Before retiring, Judge Alsup opposed any award to those firms and raised concerns about potential side dealings with publishers that might have discouraged opt-outs. Judge Martínez-Olguín signaled at a January 2026 hearing that the coordination counsel would likely receive nothing and said she would appoint a special master to investigate.¹³ On March 20, 2026, class counsel filed a revised motion seeking 12.5% of the fund, about $2.8 million in expenses, and an $18.2 million administrative cost reserve.¹⁴

If final approval is granted and no appeal disrupts the schedule, the administrator is expected to calculate individual distributions and begin paying claimants in mid-to-late 2026, with the remaining $900 million flowing in the two installments through September 2027.¹
