Overview

• Mark Cuban said Mamdani’s promises to freeze rent on stabilized apartments and open city-owned tax-exempt grocery stores “have no chance” and likened his approach to President Trump’s sweeping but implausible pledges.
• Major figures including JPMorgan’s Jamie Dimon and retailer John Catsimatidis publicly questioned the feasibility of Mamdani’s proposals and one threatened to relocate his supermarket chain if the candidate wins.
• Mamdani convened a 90-minute session with about 100 CEOs via the Partnership for NYC without retracting his plans to raise the corporate tax rate to 11.5% and impose a 2% tax on millionaires.
• Several top CEOs, including Dimon, sent deputies or skipped the briefing altogether, underscoring the persistent unease among New York’s financial and corporate circles.
• Despite sharp elite pushback, Mamdani maintains a polling lead in the general election race as he continues targeted one-on-one outreach to business leaders.
