Thomson Reuters v. ROSS Intelligence, Third Circuit opinion (29 September 2026): the market for AI training data (Thomson Reuters Enter. Ctr. GmbH v. ROSS Intelligence Inc., No. 25-2153 (3d Cir. Sept. 29, 2026), slip op. at 26)
The first federal appeals court to rule on AI training counted a developing market for licensing training data as harm under factor four. A holder whose data is copied without a licence loses the chance to license it.

In the source's own words
“Here, the evidence shows that the market for licensing headnotes as text to train AI is rapidly developing. ... By copying the headnotes for use as training data without Thomson Reuters’s authorization, ROSS usurped Thomson Reuters’s opportunity to enter that derivative market and license its headnotes for that purpose.”
