Zohran Mamdani is set to be sworn in as mayor as NYC rings in the New Year

Zohran Mamdani will become mayor of New York City as the clock ticks over into 2026 — but the celebrations are set to last through New Year’s Day. The Democrat’s team is planning two separate swearing-in ceremonies Thursday. First, there will be a small ceremony at midnight at the historic, decommissioned old City Hall subway station. Then in the afternoon there's a bigger public event on the steps of City Hall, as well as a block party to commemorate the start of Mamdani's term. His office expects thousands of people to attend the block party and says there will be performances, music and interfaith elements at the public inauguration.
