New York City mayoral election results are usually not fully “announced” at one single moment, but roll out in stages over days or even weeks, especially because the city uses ranked‑choice voting in primaries.

Same‑Night “Results”

On election night (whether primary or general):

  • Polls close at 9 p.m., and unofficial in‑person and early‑vote tallies start posting that night.
  • You can usually see first‑choice vote totals (for races using ranked‑choice) later in the evening, but they are incomplete and not certified.

Ranked‑Choice Delays

Because NYC uses ranked‑choice voting in multi‑candidate primaries:

  • If no candidate tops 50% of first‑choice votes, officials must run elimination rounds and redistribute votes, which takes extra time.
  • Preliminary ranked‑choice tabulations often appear about a week after Election Day and can update weekly until a candidate clearly passes 50%.

When A Winner Is Clear

In practice:

  • A projected or presumed winner often emerges once one candidate’s lead is larger than the number of outstanding ballots, sometimes within days, sometimes closer to a couple of weeks.
  • The final, certified results can take several weeks, since they must include absentee, military, affidavit, and other late‑arriving valid ballots.

What Happened in 2025

For context:

  • The 2025 NYC mayoral election was held November 4, 2025, and Zohran Mamdani ultimately won the race with just over 50% of the vote in the general election.
  • As with prior cycles, media outlets and election trackers provided live, unofficial returns on election night, with formal certification coming later.

How To Check The Latest

To see when this cycle’s results are being posted:

  • Watch the NYC Board of Elections site for the election calendar and reporting schedule.
  • On election night, follow trusted live‑results pages from major outlets (e.g., NPR’s New York election page) to see unofficial updates as soon as they are posted.

TL;DR: Expect partial results on election night after 9 p.m., early ranked‑choice and absentee updates about a week later, and fully certified NYC mayoral election results only after all ballots are counted, often several weeks post‑election.
