The winner of the 2025 New York City mayoral Democratic primary is Zohran Mamdani. He secured the nomination with 56% of the ranked-choice vote, decisively defeating former Governor Andrew Cuomo, who received about 44%. Mamdani, a 33-year-old state assemblyman and democratic socialist from Queens, is now the Democratic candidate for the general mayoral election scheduled for November 4, 2025.

Incumbent Mayor Eric Adams did not participate in the Democratic primary, instead running for re-election as an independent. The general election will also include Republican Curtis Sliwa and possibly Cuomo, who is considering running as an independent after losing the primary.

Mamdani's victory was notable for his ability to engage new voters and benefit significantly from the ranked-choice voting system, which allowed him to accumulate a broad base of support beyond first-choice votes. His platform includes proposals such as a rent freeze, free buses, and city-operated grocery stores.

In summary, Zohran Mamdani won the 2025 NYC Democratic mayoral primary and is the front-runner heading into the November general election.
