Anthropic Records $1.2 Billion Liability to Settle Book Rights Claims in Financial Filing
Key Facts
Anthropic disclosed in its filing with the Securities and Exchange Commission that it paid $300 million during 2025 and recorded $1.2 billion in current liabilities as of June 30, 2026, to settle the authors’ lawsuit. The financial disclosure presents the earlier payment and the remaining liability separately: an amount the company paid during the year ended December 31, 2025, and an outstanding liability balance at the end of June 2026. The settlement was announced in 2025 and then received final court approval on July 20, 2026. The disclosure therefore concerns an existing, approved settlement obligation, not a new agreement the company reached on October 27. The lawsuit concerns the use of books to train the Claude model, and the settlement covers more than 482,000 books.
The authors filed the lawsuit in 2024, alleging that Anthropic used pirated copies of their books without permission to train Claude, according to Reuters. At an earlier stage of the dispute, the judge ruled that training the model on the authors’ works constituted fair use, but found that storing more than 7 million pirated books in a central library infringed their rights. When the settlement was approved, Anthropic said the fair-use ruling on training remained the law. The agreement thus came in a case involving two distinct legal issues: training artificial intelligence on books and retaining pirated copies of them. The court’s ruling on training did not prevent continued liability for storing those copies.
Associated Press reported that claims had been filed for about 91% of the more than 482,000 books covered when it reported on the court’s approval in July 2026. The agency estimated that Anthropic would pay authors about $3,000 for each book covered by the settlement. In a statement cited by Reuters at the time of final approval, Anthropic said that more than 91% of the covered authors and publishers had claimed their shares. The plaintiffs’ lawyer added that distributions would begin as soon as possible. These claims give rights holders a path to receive their shares, while some payments remain subject to identifying the rights holders and distributing the amounts owed.
On May 14, 2026, the court held a hearing on the motions for final approval of the settlement and attorneys’ fees, but did not grant final approval on that date. A group of authors raised objections, saying the settlement amount was inadequate, the plaintiffs’ lawyers’ fees were excessive, or the agreement excluded some rights holders; the judge rejected those objections. In calculating the fees, Bloomberg Law reported that the judge used the “lodestar” method and found that calculating them as a percentage of the settlement proceeds would give the law firms an unjustified windfall given the hours worked and the size of the agreement. Before the settlement, a damages trial had been scheduled to begin in December 2025, with damages potentially reaching hundreds of billions of dollars. The agreement ended the trial path in that lawsuit after the dispute concluded in a settlement that received final court approval in July 2026.
The settlement does not cover all disputes related to the use of copyrighted works. Reuters reported that more than 25 writers opted out of the agreement and filed a new complaint in California in May 2026, and also noted other separate lawsuits that remained pending. This context defines the scope of the disclosure: the recorded amount relates to the authors’ lawsuit settlement and does not by itself establish the legal status of every other case against the company. Nor is mention of separate lawsuits enough to generalize their status to all music or news lawsuits as of October 27. The company’s disclosure of payments and financial liabilities remains tied to this specific settlement, while other disputes proceed through their own separate court processes.
