Direct answer: Election results for NYC mayor in 2025 were announced on the night of Election Day, November 4, 2025, with major outlets projecting the winner shortly after polls closed at 9:00 PM ET. Zohran Mamdani was projected/won the race, becoming the city’s first Muslim mayor and the youngest since 1892. Official certification and any late-count adjustments could extend into the following days, but the primary public call was made within hours of closing, as is typical when margins are clear. If you need exact milestone times from a specific outlet or the election certification date, I can pull those details.
