In most cases it will likely be illegal to copy copyrighted works to train generative AI without permission, because AI trained on those works can generate countless competing works and thereby dilute the market for the originals — so companies will generally need to pay for training rights.
Not due. US courts remain split. The only appellate ruling, the Third Circuit’s on 29 September 2026, rejected fair use and recognised a licensing market for training text — but for a non-generative system, and it set the generative cases apart without deciding them.
