Rosenkranz is the son of billionaire investor Robert Rosenkranz and Margaret "Peggy" Hill. His sister, Stephanie Rosenkranz Hessler, is also a legal scholar and a fellow at the Manhattan Institute.
After graduating law school, Rosenkranz clerked for Seventh Circuit Court of Appeals Judge Frank H. Easterbrook and for Supreme Court Justice Anthony Kennedy. Rosenkranz has filed numerous briefs with, and presented oral arguments before, the Supreme Court. In 2013, the National Law Journal featured Rosenkranz's Supreme Court brief that argued that Missouri v. Holland was wrongly decided in Bond v. United States. Eight years prior to Bond v. United States Rosenkranz had written a similar article in the Harvard Law Review, Executing the Treaty Power, arguing that Missouri v. Holland had been wrongly decided.
