Here is a comprehensive summary of the 2025 New York City mayoral election:

On November 4, 2025, Democratic state assemblyman Zohran Mamdani won the New York City mayoral election with 50.78% of the vote, defeating Republican activist Curtis Sliwa and independent candidate Andrew Cuomo. Mamdani's victory was historic, as he became the first Muslim and first South Asian mayor of New York City, as well as the youngest since 1892, when he succeeded Eric Adams on January 1, 2026. The race was marked by a major upset in the June 24, 2025 Democratic primary, where Mamdani defeated frontrunner Cuomo, who then launched an independent campaign after his loss, while incumbent Adams withdrew in September 2025 but remained on the ballot. Mamdani ran on a democratic socialist platform focused on affordability, including a 2% tax on millionaires, while Cuomo ran a centrist campaign focused on crime and antisemitism (declining an endorsement from Donald Trump), and Sliwa advocated tough-on-crime policies from the right. The election saw the highest turnout since 1993, driven by young voter registration, and was the first since 1969 to attract over two million total votes, with Mamdani becoming the first candidate since 1969 to receive more than one million votes. This all took place against the backdrop of Adams's federal indictment, which was dismissed in April 2025, adding to the political turbulence of the race.
