The Tax Proposal and Immediate Fallout
On April 15, Mayor Zohran Mamdani announced a surcharge on New York City second homes valued over $5 million, filming the video in front of Citadel CEO Ken Griffin’s 24,000-sq-ft townhouse at 220 Central Park South. The mayor framed the levy as an “annual fee on luxury properties … whose owners do not live full-time in the city.” Griffin responded publicly, labeling the announcement a “personal attack” and warning that Citadel might withdraw a $6 billion Midtown development project.
Budget Pressures and Tax Rationale
Governor Kathy Hochul’s office estimates the tax would generate roughly $500 million annually, a contribution toward a projected $2.2 billion budget deficit for 2026 and a $10.4 billion shortfall anticipated in 2027. Hochul’s press release emphasizes the need for additional revenue to fund city services while maintaining fiscal stability.
Key Players and Their Stakes
- Ken Griffin – Founder and CEO of Citadel; his firm plans a $6 billion expansion that could create 6,000 construction jobs and 15,000 permanent positions.
- Zohran Mamdani – New York City mayor, architect of the pied-à-terre surcharge.
- Kathy Hochul – New York governor, co-sponsor of the tax proposal.
- Gerald Beeson – Citadel chief operating officer, author of an internal memo defending the firm’s tax contributions.
- Bruce Blakeman – Nassau County executive and Republican gubernatorial candidate, vocal opponent of the tax.
- Real-estate brokers – Rachel Glazer (Compass), Noble Black (Corcoran), Michael Biryla (Agency), Michelle Griffith (Douglas Elliman) – industry observers assessing market impact.
Numbers at Play
- Tax threshold: $5 million per secondary residence.
- Projected annual revenue: $500 million.
- Citadel’s reported contributions: $2.3 billion in state and local taxes; $650 million in charitable donations to New York.
- Planned development spending: $6 billion, with 6,000 construction jobs and 15,000 permanent jobs.
- State income-tax share: Top 1 % of earners contribute 46.2 % (SmartAsset 2025 data).
Official Statements & Responses
Governor Hochul’s office framed the surcharge as a necessary revenue source, citing the $500 million estimate. Mayor Mamdani described the levy as targeting owners who “store their wealth in New York City, but don’t actually live here.” Griffin, speaking at the Norges Bank Investment Management conference in Oslo, questioned the “demonizing” of business leaders and asked whether New York could “run itself from a position of strong government that’s pro-business.” In an internal memo, Beeson called Mamdani’s invocation of Griffin “shameful,” noting Citadel’s tax and charitable contributions and the projected job creation from the Midtown project. Blakeman, in an interview with the *New York Post*, warned that the tax would “drive businesses and jobs out of the city.” Real-estate brokers expressed concern that the surcharge could depress secondary-home sales, reduce transfer-tax revenue, and alter buyer behavior, though some argued the market would ultimately absorb the cost.
Criticism & Opposition
Blakeman labeled the proposal “the latest left-wing policy that is losing businesses and jobs each and every day,” adding that Hochul’s fiscal approach reflects “spending problems, not revenue problems.” Brokers Glazer and Black called the tax “a horrible idea that’s going to backfire,” citing potential declines in luxury-home transactions. Biryla noted that high-net-worth buyers continue to acquire property but observed a shift toward sub-$5 million deals. Hedge-fund peer Bill Ackman defended Griffin’s investments and warned of an exodus to lower-tax states.
Conflicting Reports & Gaps
- The $500 million revenue projection is insufficient to close the $2.2 billion deficit, yet officials present it as a meaningful contribution.
- Legislative approval of the tax remains pending; details on assessment methods and enforcement are not finalized.
- Griffin’s meeting with Governor Hochul is scheduled but no confirmed date or agenda has been disclosed.
- The impact on the $6 billion development project is uncertain; Citadel has signaled possible cancellation but has not issued a definitive statement.
Verbatim Quotes
- “I think the willingness of a mayor of New York to make this a policy debate a personal attack, just demonstrated a ?profound lack of judgment.” — Ken Griffin, Citadel CEO
- “What upset me was the personal attack,” — Ken Griffin, speaking at the Oslo conference
- “Mamdani vilifies people who work hard, play by the rules and use their brains to create prosperity, not only for themselves but for the community,” — Bruce Blakeman, Nassau County Executive
- “I think it’s a horrible idea that’s going to backfire,” — Rachel Glazer, Compass broker

What’s Next
Griffin is slated to meet Governor Hochul to discuss New York’s “future direction,” while the state legislature reviews the pied-à-terre surcharge. The outcome of that meeting and the legislative vote will determine whether Citadel proceeds with its $6 billion Midtown project and how the proposed tax will affect the city’s fiscal outlook and luxury-real-estate market.
