Zohran Mamdani was sworn in as New York City’s mayor on Thursday, January 1, promising an ambitious agenda focused on making life more affordable for working residents. Speaking on the steps of City Hall, the 34-year-old leader said his administration would pursue universal childcare, rent relief, and free bus services as central goals. Mamdani, a prominent figure in the Democratic Party’s democratic socialist wing, won last November’s election in a decisive victory that could shape the upcoming US midterm elections. While many Democrats view him as a model for the party’s future, Republicans have begun portraying him as a national political target.

Throughout his campaign, Mamdani emphasized cost-of-living concerns and sharply criticized President Donald Trump, whose approval ratings have declined amid economic pressures. His election has generated both optimism and anxiety among New York’s eight million residents, many of whom expect major political change under his leadership. During the ceremony, Mamdani declared that his administration would serve ordinary New Yorkers rather than wealthy elites, stating, “I was elected as a democratic socialist, and I will govern as a democratic socialist.”

The inauguration featured remarks from Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez, who praised Mamdani’s vision and urged higher taxes on the wealthy — prompting the crowd to chant “tax the rich.” Despite freezing temperatures, thousands gathered to watch the event in person or via livestream along Broadway. Mamdani had earlier taken the oath privately at the historic City Hall subway station, using the Quran for his swearing-in — a first for a New York City mayor.

Republicans quickly criticized his leadership, labeling him a “radical socialist,” and warning that his policies could affect Democratic candidates nationwide. Meanwhile, Mamdani’s administration plans to raise taxes on millionaires to fund social programs and stabilize the city’s budget, according to incoming deputy mayor Dean Fuleihan. Governor Kathy Hochul has resisted higher personal income taxes but is considering corporate tax increases amid looming budget challenges. Mamdani has already adjusted one major policy position, abandoning plans to reduce mayoral control of the city’s public school system and appointing veteran educator Kamar Samuels as chancellor.

Born in Uganda, Mamdani received over two million votes in November, winning 50 percent of the total — far ahead of his closest rivals. His inauguration fundraising reached a record US$2.6 million from nearly 30,000 donors. As he begins his term, Mamdani will move from his rent-stabilized apartment in Queens to the official mayoral residence at Gracie Mansion. Though financial leaders initially expressed concern, many are now seeking ways to work with the new administration.
