Zohran Mamdani, New York City mayor since January 2026 and a naturalized U.S. citizen since 2018, faces no active denaturalization proceedings as of late 2026. Legal experts emphasize that revocation requires a federal court order proving illegal procurement or willful, material misrepresentation during naturalization, a high evidentiary bar met only in rare cases involving clear fraud tied to eligibility. Calls from some Republican lawmakers in 2025 for DOJ review over affiliations and past statements produced no filed cases, charges, or verified evidence of nondisclosure that would have altered the outcome. With roughly 14 months remaining before 2027 and the process typically involving lengthy litigation and appeals, traders assign near-certain odds to "no" based on these structural and procedural hurdles. A sudden DOJ filing supported by new court-admissible proof could still shift probabilities, though such developments remain unprecedented in similar public-office contexts.
