The Supreme Court’s 6-3 ruling in *Trump v. Barbara* on June 30, 2026, rejected the administration’s executive order limiting birthright citizenship under the Fourteenth Amendment’s Citizenship Clause, with Chief Justice Roberts writing for a majority that included both conservative and liberal justices. No petition for rehearing was filed by the July 27 deadline, and the Court has not granted rehearing in an argued case in over five decades. Subsequent administration efforts, including an August 2026 executive order and related district-court litigation, have focused on narrower categories rather than seeking review of the original decision. Traders therefore assign a 91% implied probability to “No,” reflecting the absence of any procedural vehicle or intervening development that would prompt the Court to revisit the case before year-end.
