New York’s office market is defying early fears of a corporate exodus under Mayor Zohran Mamdani, with the city recording stronger leasing and rising rents in the first quarter even as political debate over taxes and a looming $5.4 billion budget gap has heightened concerns among business leaders.
Commercial real estate firm JLL reported that leasing volume for high-quality Manhattan office space reached 8.5 million square feet in Q1 2026, vacancies fell 2.2 percentage points to 13.5%, and asking rents climbed 3.5% year-over-year. The uptick in demand overlaps with the start of Mamdani’s term and comes despite headlines that private equity giant Apollo Global Management is exploring a second headquarters outside New York — a development that has amplified worries about firms relocating to lower-cost states.
Mamdani, who attended the groundbreaking for Timbale Terrace on Feb. 18, 2026, has remained committed to campaign-era priorities of taxing the wealthy to address fiscal shortfalls, a stance that has prompted a public standoff with Governor Kathy Hochul over whether New York should increase taxes on corporations and high earners. Business groups and executives warn that policy choices now could tip the balance for companies weighing where to locate major operations. “It’s a fragile environment today and we should be careful with this budget,” Steven Fulop, head of the Partnership for New York City, told CNBC, arguing higher levies could accelerate out-migration.
Yet the market evidence is mixed. JLL highlighted major commitments that underscore continuing corporate demand: American Express in February announced plans for a new headquarters in lower Manhattan, and Bank of America in March signed a 20-year lease commitment for its New York office. At the same time, an AI-driven leasing surge is reshaping the high end of the market. AI firms accounted for roughly half of 2025’s leasing volume in the first quarter alone, JLL said, with Nscale Global Holdings’ lease at One Vanderbilt yielding a record-high New York rent of $320 per square foot and legal AI firm Harvey expanding by 92,000 square feet at One Madison Avenue.
The AI frenzy has produced both immediate gains and fresh uncertainties. JLL noted many AI tenants are taking significantly more space than current headcount requires — locking in room for anticipated hires — while demanding flexible lease terms and reconfigurable facilities. “The land grab for talent and space is immediate, but uncertainty is driving how they commit,” JLL vice chairman Evan Margolin said, warning the boom carries echoes of the dot-com era even as it is concentrated in prime Class A buildings.
Broader migration trends nonetheless persist. Finance and tech firms continue to spread operations to lower-cost Sun Belt markets: JPMorgan now has more employees working in Dallas than in New York; ARK Investment Management relocated to St. Petersburg, Florida; Wells Fargo plans to move its wealth-management headquarters to West Palm Beach; and Citadel announced its move to Miami back in 2022. Analysts caution that such shifts, if they accelerate, would erode tax revenues and deepen the city’s budget challenges.
For now, the picture is one of cautious resilience. JLL described overall demand as “stable” and development activity as “measured,” but stakeholders from landlords to civic leaders say policy choices over the coming months — from taxation to incentives — could determine whether Manhattan sustains its rebound or gradually yields ground to cheaper competing markets.
