**Trader consensus heavily favors the Supreme Court declining to accept any AI copyright case before 2027, reflected in the 87.5% market-implied odds on “No.”** The primary driver is the current stage of litigation: most prominent cases, including the consolidated OpenAI and Anthropic matters in the Southern District of New York and Northern District of California, remain at the district-court level with ongoing discovery, motions practice, and partial settlements. The sole recent appellate ruling— the Third Circuit’s September 29, 2026 decision in Thomson Reuters v. Ross Intelligence rejecting fair use for training a competing legal-research tool—still faces potential en banc rehearing, which under Supreme Court Rule 13 would push any cert petition into early 2027. Earlier SCOTUS action on AI authorship (Thaler v. Perlmutter, denied March 2026) and the absence of circuit splits or fully developed records on generative-AI training reinforce the view that the Court will wait for further percolation before granting review. Key near-term catalysts include summary-judgment hearings in cases such as Concord Music v. Anthropic and continued MDL proceedings, but these are unlikely to produce a cert-ready petition within the remaining weeks of 2026.
