This market will resolve to "Yes" if the Supreme Court of the United States grants certiorari in a case concerning artificial intelligence and United States copyright law by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A case qualifies if at least one of its claims or defenses, as described in the petition for certiorari or in the lower court's decision under review, concerns any of the following: (1) whether using copyrighted works to train, develop, or fine-tune an artificial intelligence model infringes copyright or is fair use; (2) whether outputs generated by an artificial intelligence model infringe copyright, or who is liable for such infringement; (3) whether works created in whole or in part by an artificial intelligence system are eligible for copyright protection, or who may be their author; or (4) any other claim under Title 17 of the United States Code, including the Digital Millennium Copyright Act, that arises from the training or development of an artificial intelligence model or from its outputs. An artificial intelligence model means any system that learns from data or generates content, including machine-learning and generative AI models such as large language, image, audio, and video models; the petition or decision does not need to use the words "artificial intelligence" or "AI". … (condensed)
