Anthropic flags copyright law as major risk said that could cripple AI business

Anthropic has been amid the controversy of copyright lawsuits for a while and the matter has come to the limelight from time to time. Now the company warned its investors that its business could face serious legal and financial risks if courts rule that training AI models on copyrighted material without permission is illegal. This could raise a series of challenges for the company, such as forcing the AI firm to pay hefty licensing fees, limit how it develops AI or even retrain its models from scratch. The warning appears in its Form S-1 registration statement, filed with the US Securities and Exchange Commission (SEC) on October 26, 2026.However, in the SEC filing, Anthropic claimed that it did nothing wrong. In fact, the company believes that it has the necessary legal rights for the training data used by its AI models, platform and applications. A key part of that argument is the US copyright law doctrine of fair use, which can allow certain uses of copyrighted material without permission.The company states that it has a “good faith belief” that its use or acquisition of training data “constitutes ‘fair use’ of such training data under copyright law doctrine.”However, Anthropic also acknowledges that the legal position remains unsettled. It says courts in the US and other countries have not authoritatively resolved how certain copyright rules and open-source licence terms apply to modern AI training. The company also notes that fair use is not recognised in the same way in some countries outside the US. This uncertainty could become a major problem if courts rule against the company, or if decisions in lawsuits involving other AI developers establish legal precedents that affect the wider industry.Anthropic could have to pay copyright ownersOne of the biggest risks highlighted in the filing is the potential cost of obtaining permission to use copyrighted material. Anthropic warns that if it cannot rely on fair use to train its models, it may have to pay copyright owners for licences. The company says it “may be required to pay significant fees to obtain a license to such training data”. It also warns that losing access to certain material could affect its ability to develop its models and distribute AI systems trained on that data. The concern is not just hypothetical. Anthropic has already agreed to a reported $1.5 billion settlement in the Bartz v. Anthropic copyright case, which involved allegations that it used authors’ books without permission. The settlement covers claims involving books downloaded by the company and has become a major example of the potential financial consequences of copyright disputes in AI.It could even have to retrain its AI modelsThe financial risks could go beyond paying authors, publishers or other copyright holders. Anthropic warns that an unfavourable court ruling could lead to an injunction restricting its ability to use or distribute models trained on disputed material.In some cases, the company says, it could be forced to start over. The filing warns that a ruling “could require us to retrain affected models from scratch at substantial cost.”Retraining models is a resource-intensive process that can require significant computing power, time and money. If Anthropic had to remove the influence of certain training data or rebuild affected models, it could face additional costs and delays in developing its AI products.The company sums up the stakes plainly, warning that if it cannot manage these risks, its “business, financial condition, and results of operations could be adversely affected.”Copyright lawsuits against Anthropic keep growingThe filing comes as Anthropic faces fresh legal challenges over its use of creative works. On October 23, rights holders associated with Elvis Presley sued the company, alleging that it used 274 of the singer’s songs to train its Claude AI models without permission. The plaintiffs are seeking damages of around $41 million, while Anthropic has said it disagrees with the claims and intends to defend itself fully.Back in January, Anthropic was sued for $3 billion by a coalition of major music publishers led by Universal Music Group. In June, more than 100 authors filed another lawsuit, accusing the AI firm of using their books without permission to train its models. Going further back, the Bartz v. Anthropic case saw the company agree to a $1.5 billion settlement with affected authors.- Ends
