Mayor-elect Mamdani is throwing a massive block party to celebrate his January 2026 inauguration

In case you, strangely, hadn't heard: New York City is getting a new mayor in 2026. Yes, this past November, Zohran Mamdani—a 34-year-old Democratic Socialist and State Assemblymember—won the NYC mayoral general election, defeating independent Andrew Cuomo and Republican Curtis Sliwa with 50.4-percent of the total vote.

On January 1, 2026, the mayor-elect will not only officially succeed the Big Apple's current head honcho, Eric Adams, but he will be doing so with a big street-party inauguration ceremony along Broadway. And you're all invited.

As reported by the New York Times, following a public swearing-in ceremony on the steps of City Hall held at 1pm on the first day of 2026, Mamdani will play host to a massive street party spanning seven blocks of Broadway in lower Manhattan between Murray and Liberty Streets. 

And while capacity for the swearing-in portion of the proceedings will be a bit more limited (there will be 4,000 tickets for the event at City Hall), the outdoor shindig to follow will have space for another 40,000 spectators who will be able to watch the proceedings on large screens. There will also be musical performances and “interfaith elements,” as well as remarks from Mr. Mamdani; the incoming city comptroller, Mark Levine; and New York’s public advocate, Jumaane Williams.

“This inauguration is a celebration of the movement we built, the mandate we won and the city we are prepared to lead,” Mr. Mamdani said in a statement. “Working New Yorkers are at the heart of our agenda and we invite them to join us as we welcome this new era of politics to City Hall.”

While it is still unknown whether Adams himself will be on hand to welcome in NYC's new mayor, several other political big-wigs will be there on January 1 to toast Zohran. State Attorney General Letitia James will officially swear Mamdani in as New York City’s 112th mayor in a private event at midnight, while senator Bernie Sanders will do the same duties during the public ceremony in lower Manhattan later that afternoon. 

“It is an honor to be sworn in by two leaders I have admired for years: Attorney General Tish James and Senator Bernie Sanders,” Mamdani said in a statement.
