Zohran Kwame Mamdani, a 34-year-old democratic socialist and former state assemblyman, takes office as New York City’s 112th mayor on January 1, 2026. He becomes the city’s first Muslim, South Asian, and African-born mayor, marking a historic shift after defeating Andrew Cuomo and Curtis Sliwa in the 2025 election.
Midnight Swearing-In and Public Ceremony
Mamdani swears in privately just after midnight in the decommissioned City Hall subway station, placing his hand on the Qurana first for an NYC mayor. New York Attorney General Letitia James administers the oath, with his wife Rama Duwaji holding the holy book.
A public ceremony follows on City Hall steps, where Senator Bernie Sanders swears him in again. Thousands attend a block party dubbed “Inauguration of a New Era,” featuring progressive leaders like Representative Alexandria Ocasio-Cortez.
Key Promises from Inaugural Speech
Mamdani declares: “I was elected as a democratic socialist and I will govern as a democratic socialist.” He vows to “govern expansively and audaciously,” focusing on affordability with policies like universal childcare, rent freezes for stabilized units, free buses, and city-run groceries.
He pledges to represent all New Yorkers, saying: “If you are a New Yorker, I am your mayor.” Mamdani positions NYC as a “proving ground” for progressive ideas nationwide, promising no apologies for bold action.
Immediate Actions and Reactions
His first executive orders revoke those issued by predecessor Eric Adams after his indictment and establish tenant protections. Republicans label him a “radical socialist,” while supporters celebrate a “new era” for working-class New Yorkers.
Mamdani’s rise from Queens assemblyman to mayor inspires progressives, signaling potential influence on 2026 midterms.
