Zohran Mamdani, born in Uganda and naturalized as a U.S. citizen in 2018 after arriving as a child, holds dual citizenship with no active denaturalization proceedings underway. Trader consensus at 98.7% for "No" before 2027 reflects the high legal threshold for citizenship revocation, which requires documented fraud during naturalization or specific disqualifying acts proven through DOJ processes and court review. Past political calls for investigation, including statements from Republican lawmakers and references by the Trump administration tied to Mamdani's mayoral role and policy positions, produced no verified evidence or successful action. Fact checks have found no basis for claims of misrepresentation on his application. Realistic scenarios that could still shift the outcome include emergence of new primary evidence of naturalization fraud triggering expedited federal litigation, though appeals and due process would likely extend beyond 2027 even if initiated.
