Campaign promises and governing records are different things. Zohran Mamdani took office in January 2026, and by midsummer there is enough of a record to assess rather than speculate about. Here are twenty things that have actually happened.
1. Mamdani Took Office In January 2026

Mamdani was sworn in at the start of 2026 after winning the mayoralty, making him one of the most closely watched incoming mayors in recent New York history.
2. Mamdani Delivered A Rent Freeze On Regulated Apartments

This was among the earliest concrete deliverables. Rent-stabilised tenants saw no increase, which affects a very large share of the city’s rental housing.
3. Crime Fell During Mamdani’s First Months

Reporting on his first six months noted lower crime rates, though attributing city-wide crime trends to any single administration is notoriously difficult.
4. Mamdani Moved On Free Childcare Within 100 Days

In his first hundred days the administration moved to deliver free childcare, one of the signature commitments of the campaign.
5. Mamdani’s Childcare Plan Carries A $6 Billion Estimate

That figure came from the campaign, and the scale of it explains why the programme’s funding has been contested rather than routine.
6. Mamdani Published A 100-Page Housing Plan

Block by Block was released in late May 2026, setting targets of 200,000 new affordable homes and 200,000 preserved over a decade.
7. Mamdani Announced The SPEED Reform Package

Announced in May 2026, these target pre-development, permitting and lease-up, with the administration projecting an eight-month reduction in affordable housing timelines.
8. Mamdani Appointed A New Economic Team In July

In July 2026 he named Anthony Shorris as president and CEO of the Economic Development Corporation and Lina Khan as chair of its board.
9. Mamdani Named Lina Khan As EDC Board Chair

The former chair of the Federal Trade Commission is among the most prominent antitrust figures in American policy, and her involvement signals the administration’s intended direction.
10. Mamdani Chose Anthony Shorris To Run The EDC

Pairing a veteran city administrator with a progressive antitrust figure appears to be a deliberate balance of institutional knowledge and policy ambition.
11. Mamdani Made City-Run Groceries A Top Priority

The EDC appointments came with an explicit instruction that the planned city-owned grocery stores be treated as a top priority.
12. Mamdani’s Grocery Plan Is Five Stores, $60 Million

That is the proposal as it stands. It is small relative to the housing and childcare commitments, but it has attracted disproportionate political attention.
13. Mamdani Has Not Published A Grocery Rollout Plan

As of mid-2026 there was no detailed public timetable for the stores, which critics have pointed to as evidence of slow delivery.
14. Mamdani Conceded Free Buses Would Slip

In April 2026 Mamdani acknowledged that fare-free buses would not be delivered that year, citing funding obstacles and ongoing negotiations with Albany.
15. Mamdani Restated His Commitment To Free Buses

He said he remained committed to fast and free buses and described conversations with the governor and legislative leaders as encouraging.
16. Mamdani Presented His First Budget In February

His inaugural budget included the tax measures that have defined much of the subsequent conflict with the state.
17. Hochul Gave Mamdani $1.5 Billion Instead Of Taxes

Governor Hochul announced an additional $1.5 billion for the city, including $500 million in recurring funding.
18. Mamdani’s Budget Gap Narrowed But Did Not Close

Reporting indicated the two-year gap moved from around $7 billion to roughly $5.4 billion, though a substantial shortfall remains.
19. Mamdani Marked 100 Days In April 2026

Coverage at that point described a mixture of early delivery and unresolved funding questions, which is broadly where the record still stands.
20. Mamdani’s Biggest Promises Are Still Unfinished

Free buses, the grocery stores and the bulk of the housing target are all incomplete. Six months is early, but the gap between announcement and delivery is the central question.
The bottom line: The record so far is real but partial: a rent freeze and childcare movement delivered, a major housing plan published, and the signature transit promise postponed. Most of the agenda still depends on funding decisions made in Albany rather than City Hall.
