Payments from Anthropic's $1.5 billion copyright settlement have barely begun, and already authors are pushing back: writers report receiving emails this week informing them that someone else is claiming their payout — publishers, and in some cases even literary agents. At issue is how the largest known AI copyright settlement gets divided.

The dispute stems from Bartz v. Anthropic: a judge ruled that training AI models on copyrighted material falls under fair use, but that pirating that material does not. Anthropic then agreed to pay $1.5 billion; the deal received final approval in July 2026 and payments are now moving.

Under the settlement terms, authors of nearly 500,000 titles receive $3,000 for each pirated work. If a book is still in print with a traditional publisher, the payment is split 50-50 between author and publisher. If the book was self-published, or the publisher reverted the rights by letting it go out of print, the author should receive the full amount.

That is where authors now see problems. Mystery and thriller author April Henry asked publicly: "WTF is HarperCollins playing at? They claimed one of my books on the Anthropic Settlement that reverted back at least 17 years ago AND on the same day I got a credit alert saying they had been added as my employer! (which they never were)." On the popular blog Writers Beware, Victoria Strauss says she is receiving complaints in two broad categories: publishers seeking payment for works they no longer hold rights to, and publishers claiming a full 100% when they are only entitled to 50%.

Strauss is reluctant to attribute the errors to malice — much "can be plausibly explained by poor recordkeeping," she writes, and some publishers have already said the claims were mistakes they asked Anthropic to fix. Authors Guild CEO Mary Rasenberger similarly told The New York Times she does not see "a grab by the publishers," arguing the mess is the predictable result of bad record-keeping and a confusing settlement process. Still, Strauss notes the unusually large number of reports over just two days, with authors describing the exact same errors, points to something "systemic" rather than routine glitches.

Adding surprise: a number of literary agencies are also making claims, even though, as Strauss puts it, "agents are not rightsholders in the books that they sell." Author Courtney Milan (the pen name of former law clerk and law professor Heidi Bond) was blunt on Bluesky: "Apparently some agents are trying to claim percentages on the Anthropic settlement, and I do not REMOTELY think they should do this."

Complicating matters is a technical cutoff: to claim the full 100% for a book, the rights reversion must have happened before August 10, 2022 — the "download date" in the settlement. Milan and the Authors Guild have published guides on how authors can dispute their payment allocations. For the AI industry, the fight is a lesson: even a court-approved, billion-dollar settlement leaves allocation conflicts that could shape the relationship between creators, publishers and platforms for years.
