Jamie Dimon Says He Will ‘Judge’ Mayor Mamdani on Results

Business leaders warn that progressive tax proposals risk driving firms and wealthy residents away, threatening New York’s competitiveness.

Overview

  • After a private meeting with Mayor Zohran Mamdani, JPMorgan CEO Jamie Dimon told Bloomberg on Thursday, May 21 that he will judge the mayor by outcomes rather than rhetoric and warned that “people vote with their feet.”
  • Mamdani has pushed higher corporate taxes, a 2% income‑tax surcharge on millionaires, and a proposed pied‑à‑terre levy on second homes worth more than $5 million.
  • Several financial firms and executives have signaled moves or expansions to lower‑tax states such as Florida and Texas and private retention efforts have been launched to try to keep jobs and offices in New York.
  • The pied‑à‑terre proposal cannot take effect without approval from the New York State Legislature in Albany, so implementation depends on state‑level action.
  • Coverage divides along political lines with business outlets highlighting relocation risks and conservative outlets emphasizing Mamdani’s rhetoric, while analysts warn that large departures could reduce tax revenue and slow the city’s recovery.
