**Zohran Mamdani, the naturalized U.S. citizen serving as New York City mayor since January 2026, faces no active denaturalization proceedings as of mid-August 2026.** Calls from Republican lawmakers in 2025 for a Justice Department review—citing alleged undisclosed associations or statements before his 2018 naturalization—produced no verified evidence of material fraud on his application and have not advanced to formal action. Denaturalization requires specific statutory grounds, due process through federal courts, and typically years of litigation, creating structural barriers that explain the 97.5% trader consensus against revocation before 2027. Realistic scenarios that could still shift odds include newly surfaced primary evidence prompting a successful DOJ case or an unexpected Supreme Court expansion of denaturalization authority, though both remain low-probability within the short remaining window.
