This study examines how promotion potential shapes the opinion-writing behavior of U.S. Court of Appeals judges. While prior research has explored how promotion prospects influence judicial voting, little is known about how these career incentives affect the style and content of judicial opinions. Drawing on data from the Comprehensive Circuit Court Panel Opinion (C3PO) database (2002–2012) and promotion potential scores, I find that judges with higher promotion potential write opinions that are more readable, cite a higher proportion of Supreme Court precedent, and exhibit greater legal novelty. These findings suggest that ambitious judges strategically craft opinions to enhance their attractiveness for elevation to the Supreme Court. The results contribute to our understanding of judicial behavior, demonstrating that promotion incentives shape not only case outcomes but also the way judges communicate their legal reasoning.
