Ken Griffin responded after his $238 million penthouse appeared in a 'Tax-the-Rich' video featuring Mamdani. The billionaire's pushback signals growing tension between wealthy financiers and progressive tax policies targeting New York's elite.

Citadel's chief operating officer sent a letter to employees hinting at re-evaluating New York City investments. The communication follows increasing scrutiny of ultra-high-value properties and their owners in the ongoing wealth tax debate.

The penthouse's staggering valuation makes it prime ammunition for tax policy advocates. Griffin's response suggests wealthy individuals may consider relocating capital if political rhetoric continues targeting their assets and investments in major financial centers.
