Will Trump's birthright citizenship order come into effect?

probability: 6%

rationale:

Executive Order 14160 has not taken effect since its signing on January 20, 2025, and remains universally blocked by federal injunctions apnews.com. The resolution of this outcome rests almost entirely on the pending Supreme Court merits decision in Trump v. Barbara (Docket 25-365) supremecourt.gov. A ruling is expected by early July 2026, well ahead of the August 1 resolution deadline scotusblog.com.

Evidence strongly suggests the Court is poised to invalidate the order. During oral arguments on April 1, 2026, a clear majority of justices—including several conservatives—expressed deep skepticism about the order's alignment with the Constitution and federal law apnews.com. Vote-pressure analyses and legal commentary project a 7-2 or 6-3 decision against the government scotusblog.comscotusblog.com. Furthermore, even after the Supreme Court's 2025 ruling in Trump v. CASA limited universal injunctions supremecourt.gov, lower appellate courts, including the First and Ninth Circuits, have repeatedly reaffirmed the order's unconstitutionality and maintained comprehensive relief barring its enforcement reuters.comreuters.comreuters.com.

For the order to come 'into effect,' there must be a period completely free of any federal injunction before August 1. The most likely scenario—a merits ruling striking down the EO—triggers an immediate 'No.' A 'Yes' resolution would require a surprise Supreme Court ruling upholding the order's constitutionality, a partial ruling allowing enforcement for specific categories (such as children of temporary visitors), or an unexpected procedural remedy that dissolves all existing federal injunctions simultaneously without a definitive merits rejection.

Given the prevailing weight of precedent, uniform lower-court hostility, and highly unfavorable oral-argument signals, the probability of the order taking effect is extremely low, constrained only by the inherent tail risks of the Supreme Court's potential procedural or remedial maneuvering.
